Red-tails Christo and Amelia continue nest-building and bonding in Tompkins Square

This week, red-tailed hawks Christo and Amelia have been continuing their bonding activities by nest-building and mating. Christo has been giving Amelia food and they've been spending more time in and around the park.

Below, Christo and Amelia keep an eye on things from one of their favorite perches near Avenue B.

I love watching Christo peel bark from trees. He seems to prefer bark from Chinese Scholar trees as well as American Elm.

The hawks use the bark to line their nest. Below, a piece of bark can be see laying across the top right side of the nest.

When they're not nest-building, Christo and Amelia can be seen (and heard!) mating.

This afternoon, Amelia took off from her perch on the cross of St Nicholas of Myra on Avenue A and 10th Street:

She soared past me, on her way to Christo, who was calling her for dinner.

Just after sunset, a kestrel flew over the hawk pair as they watched over the park.

Mating season has begun for Tompkins Square red-tails, Christo and Amelia

Right on schedule, Tompkins Square red-tailed hawks, Christo and Amelia, have begun mating. A fellow hawk-watcher caught them in the act on February 13, and they were seen mating again on Valentine's Day. We can expect to see an increase in mating activity over the next three or four weeks, with egg-laying expected in mid to late March.





In the meantime, the hawks are making progress on their nest.

On Sunday, I caught Amelia chowing down on a pigeon. She's an impressively large hawk, but with a full crop, she appears even bigger.

As she ate, Christo snuck up behind her.

Dinner was gone, but no worries as Christo went off to hunt for himself by lamp light. We've seen him do this numerous times - using the park lights to hunt for rats as they come out at dusk.

On Tuesday, the hawks were plagued by an intruding immature red-tail, so Christo took after it, screaming.

As nesting season progresses, the hawks will be less tolerant of other hawks in their territory, and will chase them out of the area. Today, I saw both Christo and Amelia knock a curious squirrel out of their nest, so no visitors are allowed.

All seems well in East Village hawkland, and I look forward to seeing more activity from this pair.

Hawks fighting in a cemetery and a winter snow squall in Tompkins Square

East Village red-tailed hawks, Christo and Amelia, have been busy working on their nest in Tompkins Square Park. Each day, they spend a few hours on nestorations, and I've been seeing them off to roost at sunset. For the last few days, Christo has been spending his nights inside the park within sight of the nest.

While our local pair have been carrying out domestic duties, I recently visited a few other hawks who have been wintering in the area.

This young red-tail has been hanging around the Lower East Side for the last several weeks and has a distinctive face, making it fairly easy to identify.

In the photo below, there is blood on the hawk's belly feathers, likely from tucking its talon up against its body after handling prey.

On St Mark's Place, I found another young red-tail trying to grab birds that were hiding in the cornices of buildings. The hawk would perch on one side of the street, watching the birds go into cavities, then fly over to the cornice to reach over and try and pull them out with its talon. Although an interesting hunting technique, this hawk didn't have any success while I watched, and Christo eventually ruined the fun by chasing the young hawk away.

Sub-adult red-tail

I've had several sightings of a young Cooper's hawk around the 9th Precinct on 5th Street. I can't be sure it's the same hawk each time, but the resident flock of pigeons on that block has been attracting a lot of raptor attention.

On a visit to Brooklyn the other day, I spotted a young red-tail lurking in a cemetery.

The large trees in the cemetery house a lot of squirrels, and the hawk just happened to nab one right in front of me.

The hawk's lunch was soon interrupted by a second red-tail, and the two young hawks fought talon-to-talon high in a tree.

I'm not really sure who is who, but I think the hawk on the left is the one who caught the squirrel.

After driving the intruder out of the area, the first red-tail returned to its squirrel and seemed to gulp it down so quickly, entrails got wrapped around the hawk's head. In the photo below, you can see the red squirrelgetti stretching from the hawk's throat up the right side of its face and over the top of its head.

The hawk continued eating, but was unable to dislodge the entrails from its face. Below, you can just barely see the red string under the hawk's right eye and over its cere.

In flight, the red thread is clearly visible on the right side of the face, along the edge of the eye.

After the hawk took off and left its half-eaten squirrel behind, a blue jay flew down and nibbled at the remains.

Meanwhile, an adult Cooper's hawk perched nearby.

On the coldest day of the winter so far, I visited Queens and came upon what looked like a young red-tail and squirrel just hanging out together under some bushes.  What?!?

A closer look reveals the remains of another squirrel on the ground in front of the hawk. The bold squirrel was harassing the hawk as it tried to eat its frozen prey.

As if that wasn't annoying enough, this young Cooper's hawk took a dive at the red-tail before perching in a nearby tree and watching the red-tail struggle with the rest of its meal.

The temperature at the time was 13°F with a frigid wind.

Today was a balmy 65°F, which makes it hard to believe this is what Tompkins Square Park looked like just three days ago:
