Egg in the nest? Rosie and Bobby switching nest duty – March 15th, 2014

15 mrt. 2014

It appears that there is now, at the very least, one egg in the Washington Square Park Hawk nest.

Bobby and Rosie are now regularly taking turns sitting in their nest. A fellow Hawk-watcher informed me that she saw the nest-switching behavior quite clearly yesterday after I had already left the park for the day.

I took this footage of Bobby and Rosie switching nest duty this morning. Also included in the video is footage of Rosie eating and perching in various spots.

You can hear Rosie calling out starting at the 34 second mark.

I cut the audio in a couple of the clips in order to not distract the viewer from having to hear park noise that was occurring during the action.

From Roger_Paw blog in the USA, about nesting red-tailed hawks in Washington Square Park, New York City:

At least one of Bobby and Rosie’s eggs have hatched – April 18th, 2014

The first hatching was reported by NYU to have happened yesterday morning (April 17th). The egg hatched three days after it was ‘expected’ to which is so in keeping with Rosie and Bobby’s broods.

Their eggs typically hatch two to three days later than the 28-35 days ornithologists have said Red-tailed Hawks eggs usually do. There are many conditions that affect when the eggs hatch (latitude, for example).

Fledging is said to usually occur 42 – 46 days after hatching but interestingly, all of Rosie and Bobby’s offspring in the past fledged at least two days later than ‘expected’.

If all goes well, this first 2014 hatchling should fledge between May 29th – June 2nd.

After the other webcams of birds’ nests in the Netherlands, the peregrine falcon webcam is working as well.

Montagu’s harrier migration, new research

This video is called Montagu’s Harrier – Britain’s Rarest Raptor.

Results of ten years of research into Montagu’s harrier migration were published recently.

Providing harriers with satellite transmitters proved there are three main ways for the birds to cross the Mediterranean sea on their autumn migration from Europe to Africa: through Spain, through Italy and through Greece (a newly discovered flyway, which only east European birds use).

Montagu’s harriers from the Netherlands use only the two western flyways.

Montagu's harriers flyways to Africa

In Africa, they winter in areas where they can feed on locusts.

When, in spring, the harriers fly back north, Morocco is an important stop over area for them. That is also a new discovery.

The new research was published in Proceedings of the Royal Society B.

Snowy owl vs. peregrine falcon

Remarkable footage of two Peregrine Falcons harrying Snowy Owls on a beach in New Jersey, December 2013. Filmed and narrated by Tom Johnson.

The Cornell Lab of Ornithology in the USA writes:

Snowy Owl vs. Peregrine Falcons

Snowy Owls are flooding into the Lower 48 this winter. But what happens when one raptor takes up residence on another raptor’s turf? Cornell alum Tom Johnson (2010) captured this remarkable footage of Peregrine Falcons harrying Snowy Owls on a New Jersey beach. The birds didn’t injure each other, but the aggravation of the falcons and the catlike intensity of the owls are palpable. … (And see more of Tom’s work via Flickr and Vimeo.)

Find Your Snowy: This winter could be your best-ever chance to see “Harry Potter‘s owl.” Our eBird team breaks down causes and patterns of this year’s irruption—and this live sightings map can help you locate them. If you do find an owl, please remember to keep a respectful distance to avoid disturbing these rare visitors.

For many birdwatchers the Peregrine is one of those great ‘start of the year birds’, an added bonus to a New Year outing to coastal marshes or inland wetlands, where this large and powerful falcon may be seen to strike at waders and smaller wildfowl. For others the Peregrine is a bird of the open uplands, breeding where there are suitable rocky outcrops, or a master of our western sea cliffs, where Puffin and Guillemot feature alongside Feral Pigeon as prey. Regardless of the manner in which the Peregrine enters your birdwatching realm, there is no doubting its place as a totemic species: here.

Good American aplomado falcon news

This video from the USA says about itself:

16 March 2009

This is a video of Aplomado Falcons that have been reintroduced in south-eastern New Mexico. This is an educational video to familiarize people with the movements of the falcons and the type of preferred habitat. The recovery project is a group effort involving the US Fish and Wildlife Service, The Peregrine Fund, Turner Endangered Species Fund and other organizations.

From BirdNote in the USA:

Aplomado Falcon

Species Recovery Projects Are Working!

Aplomado Falcons were once widespread residents of the American Southwest, but by the 1950s, they’d disappeared entirely from the region. Loss of habitat, loss of prey, and pesticides all played a role.

But in the 1980s, a group called The Peregrine Fund began breeding captive Aplomado Falcons. Over the next 25 years, 1,500 fledglings were set free in South Texas. At the same time, conservation pacts with private landowners provided more than two million acres of habitat. Learn more in Related Resources below.

Young American kestrels survive bear attack

This video from the USA says about itself:

American Kestrels Feed Their Nestling in Aviary Nest Box 5/14/2009

Kestrels displaying excellent parenting skills in their aviary nestbox. The mated pair (Paco and Margarita) take turns ripping and tearing mouse parts for an eager nestling. The female Kestrel remained in the aviary on a diet of live sparrows (baggies) and “Rodent Pro” mice. She was released into the Baja wild at maturity and the mated pair are in their third breeding year. Six Kestrels raised/released to date.

From the Cornell Lab of Ornitology in the USA today:

It’s a heart-wrenching sight, finding a box on the ground in ruins. But with quick thinking, Alice Droske saved four American Kestrel nestlings that were thrown from their nest in the chaos of a bear attack.

Bear-ly A Scratch

by Alice Droske, a NestWatcher, FeederWatcher, Great Backyard Bird Count participant, and Cornell Lab member for 25 years

June 24, 2013, started out like any other American Kestrel nest box monitoring day. I, along with Joe Palzkill and Judy Schwarzmeier (federally licensed banders), monitor 27 kestrel nest boxes for Beaver Creek Reserve in Fall Creek, Wisconsin. Jill Barland, our silent auction winner, was with us.

It was a beautiful warm day, and upon our arrival at Box 20, we expected to find 4 juvenile kestrels inside the nest box, which we were prepared to band. We had quite a shock! As we drove up, there was no nest box on the 10-foot pole. Our truck went deadly silent inside. We looked at each other and said, “Oh no.”

We jumped out of the truck and began searching the area for the nest box. We found the nest box broken and scattered in pieces on the ground beneath the pole. Just then, the farmer who had given us permission to place the box on his farmland drove past. I ran to the farmer and asked, “Have you seen a bear on your property?” He replied, “Yes. A rather large bear has been seen in the area.” We were fairly certain that a bear had ransacked our kestrel nest box.

We quickly began surveying the area under the nest box. To our surprise, on the ground hidden in the tall grass were the four juvenile kestrels! We assessed they had been on the ground for several days due to the amount of fecal matter and pellets. They remained quiet until Joe pushed the tall grass away from where they were huddled together. Once they were spotted, they became very noisy.

Judy began the process of aging, sexing, and banding the juvenile kestrels with Jill aiding her. Joe and I used the two ladders we carry in the truck and began repairing the nest box. We used multiple bungee cords and used the old screws to reattach the nest box on the pole. We then placed the four juveniles into the nest box, while the adult female kestrel flew overhead. Later that evening, we returned to the nest box to check that our repair work was holding up. The adult pair was flying to the nest box and dropping prey into the entrance hole. The parents continued to feed the young, and the four juvenile kestrels fledged successfully. At the end of the season, the old box was taken down, and a new box was installed. It was a happy ending to an exciting adventure for us all and an important reminder why we monitor our kestrel nest boxes so diligently.
