Black-necked Stilts

6/28/2016

Mature Black-necked Stilt Shorebird
I added this shorebird to my life list earlier this month while on a birding trip in southern Alberta. The day started out looking less than promising as rain and thunderstorms were forecast for south-eastern Alberta. Despite heading out just after sunrise and covering a lot of territory, my bird encounters were rather few and far between until mid afternoon. I had just entered the Siksika First Nations lands when I spotted a mated pair of Black-necked Stilts, foraging in a small prairie wetland slough located approximately 50 meters off a secondary highway. Surveying the surrounding area I noticed an access road leading through a natural grassland directly adjacent to the water body. A small stand of Willows provided just enough cover to allow me to approach the birds without disturbing them. After waiting a short time the birds began moving towards me as they foraged in the shallow foreshore areas. Needless to say I spent several hours photographing the birds foraging, and even managed a few flight shots when 2 very curious dogs suddenly approached the birds. The entire session lasted about 2 hours during which I also managed to photograph several pairs of Wilson’s Phalaropes and American Avocets that were sharing the habitat.

I was preparing to leave when I noticed a rather large brownish coloured bird fly over and land near a distant bull rush covered foreshore.  Grabbing my binoculars I focused in on the bird and discovered to my utter amazement that it was a White-faced Ibis. These birds have a very narrow range that just barely extends into the lower southern areas of Alberta. Although the Ibis failed to approach my location, I did manage to get several frames of the bird foraging along and amidst the bull rushes. Having added 2 new species to my life list in one day certainly proved to be an exciting and rewarding experience.

White-faced Ibis Wader

Black-necked Stilt:

Order:
Charadriiformes
Family: Recurvirostridae
Species: Himantopus mexicanus
 
This tall, slender, elegant black-and-white shorebird is an unmistakable and familiar sight at ponds and lagoons in the western and southern US as well as the southern Canadian prairies. Stilts hold the avian record for the longest legs relative to body size, and they often cross their trailing feet in flight (see photo). They often share wetland habitats with American Avocets.




Flying Mature Black-necked Stilt
The Black-necked Stilt is a study in contrasts. Bold black and white bodies balanced on incredibly long reddish-pink legs, long black bill and big red eyes; make them unmistakable amongst other shorebirds.

Black-necked Stilt Pair Foraging Shorebirds
Foraging behavior involves wadding gracefully through shallow wetlands and flooded fields, and using their height and excellent vision to scan for small invertebrate prey. Stilts also forage tactically feeling for prey by sweeping their sensitive bills through the water.
Black-necked Stilt Foraging
They breed around marshes, shallow grassy ponds, lake margins and man-made water-bodies. They also use similar habitats during migration and winter. Breeding takes place in small colonies, with several pairs sharing the same site. They tend to be gregarious by nature, and often roost together near shallow water bodies.

Black-necked Stilt Pair
Their vision and alertness enables them to quickly spot and react to predators. When disturbed during the breeding season however, all semblance of grace disappears. Agitated stilts yap incessantly, dive at predators, and feign mortal injuries (see photo). In the presence of predators, stilts quickly flock together as one intimidating black-and-white mass. This defense strategy is so effective that birds of other species often try to join the flock.

Black-necked Stilt Feigning Behavior
 Vocalizations: Flight and alarm calls are loud, continuous poodle-like yip-yip-yip, given in a long series when alarmed.

(Check out an excellent narrated video by clicking on the Bird Note link at the end of the blog)
 
Nesting: Simple scrape lined with grass in soft soil; 4 eggs; 1 brood in April-May.
 
Feeding: As described above.

Black-bellied Plover

4/13/2016

Male Black-bellied Plover Shorebird
A medium-sized shorebird of coastal beaches, the Black-bellied Plover is striking in its black-and-white breeding plumage. It is 10-13 inches in length with a wingspan of 24 inches. It has long legs, a short, pointed black bill, a round head and, a white wing stripe that is visible when it is in flight. It is the only American plover with a hind toe on its foot. Its wings extend beyond its tail when they are folded. It has a brown, black, and gray back; a white rump and belly; and a grayish-brown breast. During breeding season, its breast, face, throat, and belly are black, and it has a white stripe running from its forehead down the back and sides of its neck. Males and females look similar, but the male is more brightly colored.

Female Black-bellied Plover Shorebird
I first encountered this particular shorebird in the fall of 2015 while photographing Black Turnstones and Dunlin at Whiffen Spit near Sooke, BC.  The Plovers were foraging for invertebrates in flotsam deposited along a rocky intertidal shoreline, and didn’t seem to mind intermingling with the other two species.
 
Since that first encounter I’ve been determined to observe and photograph this bird in its very distinctive black and white breeding plumage. Non-breeding condition plumage is rather dull and includes diffused streaks to the upper breast, whitish under-parts and white-edged dark-centered brownish feathers on the back.
Non-mating Black-bellied Plover Shorebirds
Following several unsuccessful attempts at a number of different locations, I finally located a small group of males & females foraging in the early morning on a fog-shrouded beach. Despite working in less than ideal lighting conditions I managed to capture several acceptable images of the birds displaying typical plover style feeding behavior; i.e. running, pausing and plucking small invertebrates.

Juvenile Black-bellied Plover
I hope you find the images and information included with this post interesting and informative, and please don’t hesitate to leave comments and/or share this blog post.
 
Order: Charadriiformes
Family: Charadriidae
Species: Pluvialis squatarola
 
The Black-bellied Plover is the largest and most common of the three North American plovers. Its preference for open feeding habitats (lower coastal intertidal zones) its bulky structure, and very upright stance make it a fairly conspicuous species. They can generally be observed wadding in shallow water but usually do most of their foraging in exposed muddy substrates within the lower to mid intertidal zones.  
 
Feeding: Primarily forages along coasts in typical plover style: run, pause, and pluck; feeds on insects, worms, bivalves and crustaceans.
 
Occurrence: Breeds in High Arctic habitats from western Russia across the Bearing Sea to Alaska, and east to Baffin Island. Winters primarily in coastal areas from southern Canada and US, south to southern South America. Found inland during migration. Migrates south all the way to South America.

Surfbirds

Surfbirds Shorebirds
My interest in observing and photographing shorebirds is two fold: first living on Vancouver Island I have relatively easy access to both coastal and inland habitats. Secondly many of the locations are located within the Pacific Flyway for migratory birds. Additionally I have always been interested in animal behaviour, and shorebirds provide many unique opportunities to observe and photograph social behaviors under breeding and non-breeding conditions.

Furthermore Shorebirds represent excellent subjects because some species are resident and sedentary year round, while others undertake phenomenal migrations each year. The ecology of many species also includes using several different types of habitats throughout the year, including high mountain areas, swamps, muddy, rocky or sandy seacoasts. This wide geographic and ecological scope also results in a great diversity of social systems and behaviours (see Miller 1984, Communication in Breeding Shorebirds pg 169-241).
Shorelines and edges of lakes, rivers, marshes, beaches, mudflats and coastal rocky intertidal zones can be very productive birding areas fore shorebirds and waders. These birds vary widely in size, shape and color and include species such as plovers, sandpipers, egrets, herons, ibises, cranes, flamingos, bitterns and spoonbills amongst others.

A majority of my encounters with shorebirds have occurred on the pacific west coast of Canada & the US. Generally many shorebirds spend considerable periods of time foraging within 4-10ft (?-2m) of the high-tide line along rocky intertidal shores. As with most ecological transition zones, these areas tend to have higher biodiversity and biomass than either the upland or shallow littoral areas along shorelines. Considering the importance of conserving their energy, particularly on long migrations, it’s not surprising these areas are so often frequented by shorebirds. My observations suggest this also holds true for shorebirds commonly found in freshwater and wetland habitats.

Surfbird Shorebird
Surfbird Behavior
Surfbird
 
Order: Charadiformes
Family: Scolopacidae
Species: Aphriza virgate
 
A bird with a dual lifestyle, the chunky, stubby-billed Surfbird breeds in the high mountain tundra of Alaska and the Yukon, and then migrates to the rocky Pacific coasts of both North and South America. Some individuals have been reported to migrate as far as southern Chile, a round trip of over 19,000 miles (30,500km) each year. This extremely large migratory range is amongst the largest of all North American shorebirds. With the exception of breeding seasons, Surfbirds spend a majority of their lives along rocky intertidal shores.

Surfbird Behavior Shorebirds
VOICE: Flight call is a soft whiff-if-fi; feeding flocks soft, chattering whik; display call is a kree, kree … ki-drr ki-drr, and quoy quoy quoy.
FLIGHT: Flight is swift and direct, with strong, powerful wing beats.
NESTING: Shallow lined depressions on vegetated or bare ground; 4 eggs; 1 brood; MAY-JUNE.
FEEDING: Eat mainly insects, especially beetles; also aquatic mollusks and crustaceans, such as mussels and barnacles.
OCCURRENCE: Except when breeding, Surfbirds spend their lives along rocky intertidal shores. Breeds in low to high-elevation steep, rocky slopes of ridges and mountains; the rest of the year is spent exclusively on rocky Pacific coastlines, typically within 6-1/2ft (2m) of the high tide line. This is the narrowest range of all North American shorebirds.

The two images below illustrate territorial behavior between a group of Surfbirds and an intruding Black Turnstone.

Wilson's Snipe

3/12/2016

0 Comments

 
I have photographed this bird several times over the last 10 years, occasionally in BC but more often in Alberta. The most recent encounters occurred in several different locations in South-western Alberta.

Picture
Perhaps my most memorable experience resulted in not only getting some fantastic images of a Wilson’s Snipe, but also capturing my first images of a Yellow-bellied Sapsucker. I was intently following and photographing a foraging Snipe when suddenly a Yellow-bellied Sapsucker appeared in my peripheral vision. Amazingly the bird had landed on a fence post not more than a meter and a half from where I was standing, partially hidden by a small stand of willows. Trying very hard to avoid startling the bird, I turned my body and camera very slowly through approximately 110 degrees, and managed to fire off 8-10 frames before the bird flew off. The experience once again reminded me that wildlife photography often involves hours of patience and persistence followed by seconds of mayhem. A little luck can also be helpful at times.

Picture

Wilson’s Snipe:  









Order-Charadriformes;  Family-Scolopacidae;  Species-Gallinago delicate
 
Also known as the Common Snipe, this secretive and well camouflaged member of the sandpiper family has an unsettled taxanomic history; but is now classified individually. On its breeding grounds Wilson’s Snipe have been known to produce rather eerie sounds during their arial, mainly nocturnal, display flights. The birds tend to fly up silently from the ground, and then descend quickly from heights of up to 300 feet (100m) with their tail feathers spread, producing a unique, loud and vibrating sound through the modified tail feathers.


Picture

Voice: Alarm and overhead flight call is a raspy kraitsch; perched and low flying breeding birds also give repetitive, monotonous kup-kuo-kup-kup in alarm or aggression displays; also known to produce distinctive whistling sounds during territorial displays.
Nesting: Elaborate woven nest lined with fine grass usually constructed on the ground, sedge, or moss.
Generally lay 4-eggs and produce only 1 brood in May-June.
Feeding: Forages in mud or shallow water; probes deep into subsoil; diet includes mainly insect larvae, but also crustaceans, earthworms, and mollusks.
Occurrence: Widespread from Alaska to Quebec and Labrador south of the tundra zone. Breeds in a variety of wetlands, including marshes, bogs, and open areas with rich soil. Winters further south, where it prefers damp areas with vegetative cover, such as marshes, wet fields, and other bodies of water.

Shorebird photography can be exciting and rewarding, but it can also be very frustrating. Particularly if your subject matter happens to be a flock of smaller shorebirds like Dunlin or Black Turnstones. The foraging behaviour of these species usually involves  a lot of stop and go type action as they move along the shoreline in small groups probing for food. Other species like the Wilson's snipe tend to be more secretive, and generally forage amongst bull rushes, sedges, and other types of aquatic vegetation, making it more difficult to capture images without a lot of extraneous unwanted elements in the frame. Here are some links to information I've found very helpful in raising my percentage of keeper images.

Wilson's Phalarope

3/11/2016

Wilson’s Phalarope: Order-Chadardriforms; Family-Scolopacidae; Species-Phalaropus tricolor
 
I usually take a photo trip to Alberta during spring and fall migration periods, and was out on an early, somewhat cool, May morning in 2012. Encountering these birds was a bit of luck as I had finished checking out most of my favourite locations, and was ready to head back to Cochrane. This small prairie slough was located directly adjacent to a Trans Canada Highway on ramp and I certainly wasn’t expecting to come across Wilson’s Phalaropes at this location. One of the advantages I find to photographing birds in the spring, is you can usually find mated pairs, at any one location.

A truly American phalarope, Wilson’s is the largest of the three phalarope species. As you can see from the mages below this is one of only a few species in which the females tend to have more colourful plumage than the males. Unlike its two relatives, it does not breed in the Arctic, but in the shallow wetlands of western North America, and winters mainly in continental habitats of Bolivia and Argentina instead of in the ocean. This species can be found employing the feeding technique of spinning in shallow water to churn up adult and larval aquatic insects, or running in various directions on muddy wetland edges with its head held low to the ground while chasing and picking up insects. This bird is quite tolerant of humans on its breeding grounds, but this attitude changes immediately before migration, as it has gained weight and its movement becomes sluggish.

Nesting: Simple scrape lined with grass; 4 eggs; 1 brood; May-June.
Feeding: Eats brine shrimp, various insects, and insect larvae.
Occurrence: Breeds in shallow, grassy wetlands of interior North America; during migration and winter, occurs in salty lakes and saline ponds as well as inland water bodies. In winter, tens of thousands can be seen in the middle of Titicaca Lake in Bolivia.

Sooty Grouse

3/10/2016

Sooty Grouse: Order-Galliformes, Family-Phasianidae, Species-Dendragapus fuliginosus
 
Recalling the numerous outings with my father as a youngster, the Sooty Grouse was one of the birds we frequently encountered. I also remember being somewhat amazed at how close I was able to come to these birds, later learning that this is quite characteristic of most grouse species in general. There were also many occasions when we would encounter them on or beside roadways, often almost running the birds over with our vehicle.

And so it was not surprising when I encountered both of the birds pictured below while driving. The first bird (Male in Mating plumage) was observed while traveling a forestry/logging road near the small coastal community of Jordan River, on Vancouver Island. Being early spring and characteristic of these birds, it was performing an elaborate mating behaviour for a female standing at the side of the roadway.


Picture
Picture
The sooty Grouse, like the Dusky Grouse, was recently reclassified as a separate species. Although primarily distinguished by its restriction to coastal mountain ranges, plumage and behavioral displays help differentiate the male Sooty Grouse from the very similar looking Dusky Grouse.
 
During courtship displays, which are most often performed in trees, the male Sooty Grouse show rough yellow air sacs. Female and chicks have a browner overall appearance to their plumage than those of the Dusky Grouse.
 
Voice: Loud six-syllable hooting: also growl hiss, cluck, purr.
Nesting: Shallow depression lined with dead vegetation, usually under small pine trees: 5-8 eggs; 1 brood; March-May.
Feeding: Feeds primarily on evergreen needles, especially Douglas Fir; will take leaves, grasses, fruit and insects when seasonally available.
Occurrence: Found west of the Rocky Mountains in Canada and the US, from sea level to the timberline. Breeds at lower elevations in open areas with grassland, forest clearings and shrubs, and moves up into thicker evergreen forests at higher elevations in winter.

Capturing Beautiful Landscapes

3/3/2016

Learning how to shoot amazing landscape images that give a dramatic sense of place is an essential skill.
Picture
Here are some simple tips to help you develop those skills.
1) Be Prepared:
Be prepared to do a lot of walking to find the perfect viewpoint. Try going out in good light, at dawn or dusk (the latter two are often referred to as the golden hours when the sun is low to the horizon producing warm colored light effects. Think in advance about where the light will be coming from and choose the right time of day to be there.

The Photographers Ephemeris (TPE) is a very useful app that I've been using to plan my landscape photography outings for some time now.  Essentially TPE is a map-centric sun and moon calculator that shows you how the light will fall on the landscape at a specific location for any given date and time for almost anywhere in the world.  TPE's map-based approach means you can search for any place name (eg. Esquimalt Lagoon) or position a map pin exactly where you want it on the planet. The app is available from the iTunes store and runs on iOS and Android mobile devices.

Here are two other clickable links for more information about the app:
  1. Light Stalking
  2. Crookneck Consulting

2) Don't Forget the Tripod: Set your camera on a tripod so that it is nice and steady, to reduce any blur caused by camera movement/shake.

3) Be Creative: Play with your composition. Landscapes often work well with the horizon line positioned either in the top or bottom third of the image, rather than in the center.

4) Neutral Density Graduated Filters: Although I will be blogging on this subject next week, ND Graduated filters are essential for creating dramatic landscapes, because they help reduce the brightness of the sky thereby balancing the exposure to match the foreground. I employed this technique to capture this dramatic image of a prairie storm over Cochrane Alberta.

Neutral Density Filters-What Are They, How & When to Use Them

3/2/2016

0 Comments

 
Have you ever wondered how some photographers produce those shots of clouds that look amazing and water that looks like silk running over rocks? Or perhaps those wonderful hazy looking images, where the movement is really blurred even though the scene was photographed in broad daylight?
 
Well the answer is........they used Neutral Density filters.
 
As landscape photographers we normally strive for the perfect sharp image and accomplish this by selecting a small aperture, which in turn results in fairly long exposure times.  The problem we often encounter however is our exposures are almost never long enough to blur clouds or water movement, especially during broad daylight.
 
What are Neutral Density filters?
 
In order to achieve exposure times ranging from several seconds to minutes, we need to reduce the amount of light, and this is essentially what a Neutral Density (ND) filter does.  An ND filter is simply a special semi-transparent piece of glass, resin or polyester (plastic) that effectively blocks out light from reaching the digital sensor. As a result our   exposure times are extended by seconds or minutes depending on the strength of the filter.  
 
How to Use ND filters
 
The good news is ND filters don’t radically affect the image that our cameras capture, but merely slow down the amount of time it takes for the sensor to actually record the image.  However if used when elements of our scene are moving (e.g. water, clouds or even people) they open up a world of creative possibilities.

For example the image below was created using a regular shutter speed, and the effect was to freeze the waterfall; as a result it looks static and rather dull.

Picture
Picture
Use a ND filter to capture the water as a blur and it conveys a sense of movement. Place an individual in the foreground ....... and MAGIC!!

As you can see ND filters give you the flexibility to set the aperture and shutter speed you want, rather than what the conditions dictate.  I have also use ND filters  on a sunny day to slow things enough to create a sense of movement, but they’re even more effective around dawn or dusk, when they can turn an already-slow exposure into one several seconds long. This technique was used below to turn a surging tide into a gentle mist.

Picture
When to Use ND Filters
I have found that for waterfalls you don’t necessarily need a very long exposure to capture motion blur. The water is moving so rapidly, so a three-stop ND filter will work fine in the middle of the day.

However, if you want to achieve a similar effect with a seascape you’re looking at an exposure that lasts 30 seconds or more, as the sea and clouds aren’t moving as quickly.

Shooting during the ‘golden hours’ at dawn or dusk will help, as the lower light levels will facilitate longer exposures – and of course the quality of the light will help to produce great images!

ND filters aren’t just for blurring the elements – you can use them to make moving people disappear! You’ll need a really long exposure of several minutes, but people walking through a scene will simply vanish. This technique is often employed by  architecture photographers when shooting crowded tourist hot-spots.

Furthermore it’s not just slower shutter speeds that can be obtained by using ND filters. If you’re shooting portraits on a bright, sunny day, for example, you may find you can’t shoot at wide apertures to obtain a shallow depth of field because it requires a shutter speed that exceeds the fastest available. Adding an ND filter will enable you to select a wider aperture.

Making sense of the numbers on ND filters

Confusingly, different ND filter manufacturers use different scales to denote optical density. You can use the table below, (created by Digital Camera World) to ensure you get the right filter for your needs.

Picture
Well that's about it for this week. Please don't hesitate to contact me if you have any additional questions with respect to selecting and using ND filters. 

In my post next week  I will discuss how and when to use Graduated ND filters.  Thanks for visiting and lets get out there and capture some great images. Till next time "Keep your eyes open and your lenses dry.  Good Shooting Everybody".

Anna's Hummingbird Feeding Young
Earlier this year I had the opportunity to photograph a Anna's Hummingbird brooding and feeding her young. It soon became apparent that my initial attempts were causing the adult to remain away from her nest for extended periods of time. I also discovered that the EOS app. for taking wireless remote control of my cameras functions was not compatible with my  EOS 7D & EOS 1D Mk IV camera bodies. 

Following some research on the internet I discovered a very useful product called WEYE FEYE available from a US company called XSORIES. Click Link XSORIES.  

The Weye Feye is an innovative external device that enables remote and wireless control of a DSLR camera via a smartphone/tablet application. The device generates its own WiFi network and connects to the DSLR via a USB port. It is compatible with most Nikon and Canon DSLR cameras. The App is available as a free download for Android and iOS. 

The high-performance central processing unit and long-life battery ensures its self-sufficient operation.  A LiveView function and the built-in web server allow you to edit the images, transfer them to your mobile device and share them instantly on social networks. The device lists for $149 US, however I purchased mine from a local London Drugs for just under $200 Cdn.

Observations of a Nesting Pair of Pileated Woodpeckers-Weeks 5 & 6

5/20/2015

1 Comment

 
Pileated Woodpecker Nestsite












Week #5 (May 3 – 9) Observations were conducted on the 5th and 8th. Behavior typical of parents brooding nestlings continued and audible sounds are being heard coming from within the nest cavity. Hatchlings would have been born naked and helpless; remains of the yolk sac would still be attached to the abdomen; eyes would be covered with a membrane with no evidence of slits and upper and lower beaks would both be tipped with egg tooths.

Rapid growth in body length and wing chord would be occurring, and has been reported to slow in the second week as feathers begin to erupt. Traces of lines across the eyelid would have occurred on day 3-4 and the eyes would have opened by day 9-10. The newly hatched young have been reported being able to raise their heads and open their beaks by the end of the first week, and would be able to raise themselves on their legs and flex their toes. As the nestlings began molting into juveniles most body feathers would have erupted by day 7 and the red cheek stripe of a male bird would become visible by day 14. The young will be able to control their body temperatures after about day 10 at which time brooding behavior will stop.

Both parents appear to be foraging and feeding the young nestlings equally at intervals of between 35-60 minutes. On May 3rd I was hearing occasional rasping begging sounds coming from within the nest cavity, and stronger rasping sounding like a beehive were heard on May 9th. All feeding activity appears to be occurring within the nest, with parents arriving silently (no prior vocalizations) and briefly remaining perched outside the nest cavity entrance.
They are then entering with only their tail feathers remaining visible outside the entrance and then disappear completely into the cavity.
This type of behavior has been reported to occur when nestlings are 7-15 days old. After a minute or so the adult reappears at the entrance with a fecal sac and flies off. The fact that young are actually producing these is an important adaptation for the purpose of maintaining nest sanitation.


The image below is of the female about to leave the nest with a fecal sac in its bill.

Pileated Woodpecker

Later in the week I  observed the adults feeding the young either partially in the cavity with lower body sticking out or with the entire body remaining outside of the cavity (see image above).  

Additional observation during the week included the following:
  • adult birds have been vocalizing at a distance, presumably as they are foraging for food items;
  • upon arriving for a feeding event they are perching on a tree near the nest tree for periods of up to 5-10 minutes, preening and bobbing their heads as if inspecting the tree for additional food items.
  • Occasional drumming on a near by tree has also been occurring before a silent arrival is completed.

Week #6 (May10-16)
Three juveniles are now appearing at the entrance begging for food. Feeding intervals have increased to between 40 & 80 minutes.
Pileated Woodpecker Feeding Young
Young are being fed by adults regurgitating food and the food items are reported to consist of primarily invertebrates. They are now being feed while peering out the cavity entrance, giving repetitive yuk calls with raised crest, and rasping loudly while jabbing at the parents bill. The young beg to be fed and vocalize throughout the entire feeding interval. They then generally remain at the entrance for up to 2 minutes before disappearing back into the nest cavity.  They are also giving a churring sound and a new adult-type vocalization sounding like a-nah. I have also begun hearing an occasional cuk sounding, suggesting the young are approaching 16-19 days old. 

The image below is of the adult male regurgitating food prior to feeding the young juvenile. Notice the extremely long tongue.
Pileated Woodpecker Nestsite
Pileated Woodpecker Fledglings
As illustrated in the image below the parents are feeding 3 healthy juveniles, and it appears there are 2 males and 1 female.

Their Their appearance at the entrance confirms they can now climb up the sides of the cavity. According to other researchers this behavior has been observed as early as days 11–13 and is well established by days 16–19. Towards the end of the week the young were being fed about every 60 – 90 minutes, and all feeding activity is occurring at the cavity entrance. Feeding intervals will apparently increase to every 2 hours next week. Young are being fed by adults regurgitating food items and then inserting their bills into the throat of the young. Food items are reported to consist mostly of invertebrates (grubs beetles insects). Adults are also vocalizing from a distance prior to arriving and again after leaving the nest tree.

I've included the two images above to illustrate how quickly the juveniles are developing. The first image was taken on May 15th. The 2nd image was taken on Wednesday May 20; i.e. Week #7 
Week #7 (May 17-23) In addition to taking more still images I also plan to shoot some video of the juveniles being feed. 

Anticipate observing the following behaviors this week:
  • Parents will cease removing fecal sacs 2-5 days before the young fledge;
  • Juveniles vocalizing, flexing their wings, and teetering on the rim of the nest cavity prior to actually leaving the nest.
  • The young fledging and leaving the nest tree.
It will be sad to see them go but I've had a great time watching, documenting and photographing this whole process. I still find it amazing that they chose to nest within 2 meters of the hiking trail. However the remnants of three older nest cavities suggests the birds are quite at ease with the human activities (including barking dogs) occurring below them. Check back next week for a complete summary of Week#7, and hopefully some interesting video.
