Cornell great blue heron eggs are hatching


From the Cornell Lab of Ornithology in the USA:

Cornell Herons are hatching!

The first chick hatched out today as thousands watched live.

Bird Cams News Flash: Herons are hatching!

The Great Blue Herons in Sapsucker Woods have hatched their first egg! A small, damp nestling emerged from its egg at 2:05 P.M. while thousands of viewers watched and shared in the excitement. We expect that the next few days will see the other four eggs hatch as well, so don’t miss your chance to watch more new herons enter the world. Watch heron cam now.

The next eight weeks will be a blur of action as the parents try to keep up with the nestlings’ ravenous appetites and the youngsters clamor for attention and space. While you’re waiting for views of the young herons, you can also check out our Red-tailed Hawk cam  as they near their first flight (expected during the first week of June), as well as incubating Ospreys and kestrels thanks to our cam partners. We’ll continue to post updates on the Bird Cams Facebook page and on twitter at @birdcams. Thank you for watching.

Strange birds’ nests contest


The Cornell Lab of Ornithology in the USA writes about the subject of this video:

Funky Nests Contest

Whether you find a robin‘s nest on a park statue or a hummingbird‘s nest on your wind chimes, your picture of a bird nest in a funky place can win big in the Cornell Lab of Ornithology’s Funky Nests in Funky Places contest. With nesting season underway, this contest challenges everyone to get outside and watch nature in even the most unexpected places.

“Just start looking,” says Karen Purcell, who created the contest several years ago as part of the Cornell Lab’s Celebrate Urban Birds citizen-science project. “Past experience has shown us you can find bird nests in the most surprising places. We’ve seen them in helmets, old boots, stoplights, store signs, car tires, clotheslines, mailboxes, potted plants, and even a stuffed moose head!”

The Funky Nests contest began May 1 and lasts until June 15. Entries may be photos, videos, artwork, poems, or stories. You don’t have to be a bird expert or an expert photographer. People of all ages are welcome to participate as individuals or with a class, community center, or afterschool program. Prizes include binoculars, bird feeders, cameras, an iPad, and more.

…  visit www.FunkyNests.org to enter the contest. Entry deadline is June 15.

Birds’ Mother’s Day

Best Maternal Moments Captured Live

In honor of Mother’s Day, we want to celebrate some exceptional bird “moms” that go the extra mile for their chicks. Watch these intimate moments in the lives of three Bird Cams mothers, each revealing the universal struggles and joys of motherhood. Then, tune in to see what’s happening live on Bird Cams.

  • Dinner is Served—Big Red, the fierce Red-tailed Hawk mom, delicately serves up dinner with her powerful beak. When she leaves to get more provisions, the nestlings fall asleep in a warm pile and wait for her to return.
  • Protecting the Nest—The formidable Great Blue Heron mom bravely defends her nest from an owl attack. Her bone-chilling screams scare the owl away and quickly bring the male to her side.
  • Giving Them Wings to Fly—That moment when your kids are grown and have to make their own way in the world is terrifying, but necessary. Iris, the Osprey mom at Hellgate Canyon, Montana, looks on anxiously as her oldest chick leaves the nest for the first time.

Do you have an “aww” moment captured in a photo or on video? Submit your photos and videos to our Flickr group.

American hawk, heron, other nest webcams update


This video from the USA says about itself:

In the early morning hours of Monday April 22, two of the [red-tailed] hawk eggs hatched. Even before the young were out of their shells, Big Red and Ezra started bringing food to the nest. In this video, Big Red delicately feeds their young by tearing the prey into small pieces, giving the hatchlings just a little bit at a time. The hawks appear to be bringing a range of prey for the young; birds, snakes and rodents. In this video the young are just over a day old and are being fed what looks like a small rodent.

To watch the hawks live, go to http://allaboutbirds.org/cornellhawks.

From the Cornell Lab of Ornithology:

Three Fuzzy Chicks in the Hawk Nest

Viewers of the Cornell Hawks cam can tune in to see Big Red and Ezra feeding three bobbly headed, downy-white chicks. The first two hatched early morning on Monday, Earth Day, as thousands of people watched. The third youngster entered the world two days later. Big Red and Ezra have been busily provisioning them with chipmunks, starlings, snakes, and other prey, which they carefully tear into small pieces before giving to the nestlings (watch a video). The first nestling’s official hatch time was 6:06 a.m. on Monday, April 22, and we have contacted the winner in the Guess the Hatch contest.  Watch the nestlings live.

Concerned about the nestlings? Over the next few days you may see the nestlings pecking at each other. Don’t be alarmed—as long as there is a steady supply of food this behavior usually dissipates without harming the chicks in about 7–10 days.

Heron chicks on the way! Not to be overlooked, the Great Blue Herons outside our office laid their fifth egg this week. Keep an eye out

Osprey and Kestrel Cams Return

If herons and hawks aren’t enough to sate your cams appetite, we’re happy to announce the return of two Osprey cams from Project Osprey (in Hellgate Canyon and at the Dunrovin Guest Ranch, in western Montana) and an American Kestrel cam from The Peregrine Fund in Idaho. The Dunrovin Ospreys and the kestrels are sitting on eggs. A female at the Hellgate Osprey nest is still waiting for a male to join her.

This is a video chronicle of a Red-Tailed Hawk chick from one to six weeks, after hatching in its nest high in a Saguaro cactus. It has all been condensed into an sub eleven minute video with other wildlife scenes mixed in. I do very little talking during this video and try to let the pictures speak for themselves.

From the Cornell Lab of Ornithology in the USA:

Bird Cams News Flash: Hawk hatch has begun!

We’re excited to share the news with you that the first egg in the CornellHawks nest has begun pipping! Earlier today a small hole was seen forming and there is a high likelihood of seeing a new downy nestling enter the world over the next 24 hours. “Pipping” refers to the process of the chick initially breaking through the shell, using a hard projection on its bill called the egg tooth. The resulting hole is the “pip” that the chick then enlarges to finish hatching. The hatch follows 38 days of stalwart incubation by Big Red and Ezra in often windy and rainy conditions (check out some highlights on YouTube).

Don’t miss your chance to see the young hawk emerge and share your excitement with the cams community at http://allaboutbirds.org/cornellhawks. As if hatching hawks aren’t enough to keep you busy, be sure to also check out the Great Blue Heron cam (http://allaboutbirds.org/cornellherons) where last night a fourth egg was laid during the darkness of night.

We’ll continue to post updates on the Bird Cams Facebook page (facebook.com/birdcams) and on twitter at @birdcams. Thank you for watching!

Great blue heron nest update


This video from the USA says about itself:

Female heron lays first egg.

Apr 14, 2013

Cornell Lab Great Blue Herons Nest 4-14-2013

Video is edited for lengthy time between contractions and finally letting viewers see egg.

And this video says:

On Tuesday April 16th at about 16:43, the female heron laid her second egg of the 2013 season. The first two minutes of this video show her restless, getting up and down, with the male standing by her side. As soon as he takes off, the second egg arrives. When he comes back a moment later with a branch for the nest, vocalizations are heard and he walks over to investigate the new egg.

Watch all the heron activity live at allaboutbirds.org/cornellherons

The Cornell Lab of Ornithology in the USA writes about this today:

Days of courting and mating by the herons have produced two pale blue eggs, now nestled in among the sticks of the nest. On average, herons lay 2-6 eggs before completing their clutch, laying each egg 2-3 days after the last; this means if you’re hoping to catch it live, be sure to tune in on Thursday to see what happens!

Heron courtship begins in Sapsucker Woods

Courtship begins between the Great Blue Herons in Sapsucker Woods

From the Cornell Lab of Ornithology in the USA:

Bird Cams News Flash: The Herons Are Back!

We’re excited to share the news with you that the Great Blue Herons of Sapsucker Woods have returned! The male from past years (known by the missing rear toe on his right foot) was first spotted on April 4, and just yesterday (April 8) a female joined him on the nest. For more than two hours, the herons perched near one another, taking time to preen, joust with their bills, and tug at the sticks in the nest, as the spring peepers chorused and the light grew dim.

In past years, these days of courtship have rapidly led to the beginning of egg-laying and incubation, and this nest has a four-year history of successfully fledging young. Don’t miss the incredible courtship of these beautiful birds, viewed live from 40 feet above Sapsucker Woods Pond at http://allaboutbirds.org/cornellherons

We’ll continue to post updates on the Bird Cams Facebook page (facebook.com/birdcams) and on twitter at @birdcams. Thanks for joining us as we share the beauty and excitement of another breeding season unfolding in Sapsucker Woods!

North American birds, forests and houses


This video from the USA says about itself:

From the Raquette Lake Inlet and the Boquet River to the Blue Ridge area and Lake Placid, NY experience some of the great birds of the Adirondacks including Great Blue Herons, Bald Eagles and Mallards.

From Wildlife Extra:

Houses impact on birds for up to 200 metres into surrounding forest

Some species keeping their distance, while others cosy up to human neighbours

February 2013. According to a study by the Wildlife Conservation Society (WCS), impacts to bird communities from a single rural, “exurban” residence can extend up to 200 metres into the surrounding forest. The study also determined that sensitive bird species such as the hermit thrush and scarlet tanager prefer unbroken forests with no houses. Others, like the blue jay and black-capped chickadee, seem to like having, and often thrive with, human neighbours.

20 species studied

As part of the study, scientists sampled the presence of 20 species of birds both near and far from 30 rural residences in the Adirondack Park. Calculating their occurrence at increasing distances from the residences, they determined that “human-adapted” species are 36 percent more likely to occur near the homes than in the surrounding mixed hardwood-conifer forests, and that “human-sensitive” species were 26 percent less likely. Beyond 200 metres, occupancy rates were similar to the surrounding forest.

Exurban

Rural exurban development is residential development existing outside of cities and towns, and is generally characterized by larger lot sizes (5-40 acres or more) and lower density than suburban development. Exurban residences exist within an otherwise unaltered ecosystem.

Exurban homes change the environment by bringing vehicles, noise, lights, pets, people, and food sources into the forest, as well as by physically altering and fragmenting habitat. These changes can have myriad impacts, including altered species behaviour and composition, increased human wildlife conflicts, new predator-prey dynamics, and decreased biotic integrity (a measure of how pristine a wildlife community is).

Ecological footprint of development can be much larger than its physical footprint

“Adirondackers take great pride in their surroundings and try not to unduly disturb the natural setting in which they live,” said WCS Adirondack Program Science Director Michale Glennon. “A key finding of the study is that the ecological footprint of development can be much larger than its physical footprint. We found that even a small home and lawn can change bird communities some 200 metres away, which means more than 30 acres of the surrounding landscape, depending on what types of activities are occurring on the residential property. It is important that we learn how birds and other wildlife react to particular kinds of human activities, and find ways to minimize the negative impacts for wildlife in exurban areas.”

Sensitive birds

The study found that species sensitive to human impacts include the black-throated blue warbler, black-throated green warbler, hairy woodpecker, hermit thrush, ovenbird, scarlet tanager and the winter wren. The presence of some species, like the scarlet tanager, are a good indicator of undisturbed forest health.

WCS Livelihoods and Conservation Coordinator Heidi Kretser said, “Some wildlife species are sensitive to exurban development and are less likely to be found near those residences than adapted species. More sensitive and less common species could ultimately be displaced from the area as a result of this kind of development.”

The study was modelled after one conducted in a shrub-oak ecosystem in Colorado where scientists calculated a 180-metre ecological effect zone based on their results. Glennon and Kretser believe that the similar results in two different ecosystem types may indicate that human behaviours associated with exurban homes play a larger role in shaping avian community characteristics nearby than do habitat alterations created by construction and clearing.

While breeding bird communities were used to measure the impacts of exurban development in the study, the authors note that birds can serve as valuable indicators of overall biodiversity.

Adirondack Park

WCS Adirondack Program Director Zoe Smith said, “The Adirondack Park is one of the last large, intact, wild ecosystems in the north-eastern United States, and it is becoming increasingly important as we face global threats like climate change. As we strive to find a healthy balance between conservation and the needs of humans within the park, we need to fully understand the impacts of different development patterns. This research is another step toward that understanding and can help inform decisions on development and land-use in this rural landscape.”

The report appears in the current online edition of the Journal of Landscape and Urban Planning. Authors of the study are Drs. Michale Glennon and Heidi Kretser of the Wildlife Conservation Society.
