5th Avenue

I watched the nest at dusk on Friday and for about half an hour Saturday afternoon. 

On Friday, Pale Male brought prey to Lola.  He stopped twice while taking it up to the nest. Once on a balcony on a building a block south of the nest and once on a ledge on a building north of the nest.  The prey was a bird.  Once he got to the nest, Lola switched off and ate on a terrace a few blocks away.  After about half an hour she returned to the nest and Pale Male exchanged places with her on the eggs.  He then went off to the terrace to see if their were leftovers.

On Saturday, the "boys on the hawk bench", were kind enough to point out a new perch for Pale Male, on top of the building just to the north of nest.  They're doing construction by the water tower which has a large scaffold with a tarp around it.  He likes to sit on the upper right hand corner on days there are no construction workers.

Riverside Hawks

Things seem to be just fine for the Riverside Hawks, although a rat baiting station in a small garden on the south side of Riverside and 79th Street, does have me worried.  Will rat poisons still be a problem this year?  Beyond this garden, it seems that a major source of poisons in city parks is from restaurant concessions, but there is still no legal language in their contracts to monitor/control their extermination plans.

When I arrived in the early afternoon, the male came in.  He landed on one branch, visited another with some old prey (either cached food or leftovers from his mate), and then visited the nest.  He then left and preened on a branch just north of the Boat Basin Café and flew out of sight.

Nest Height Change On Fifth Avenue

Below is a split shot of Lola and Pale Male's nest, the left is from last year and the right is from a few days ago.  Both were taken in March.  It looks like the nest is now an inch or two higher.  Cross your fingers for a positive outcome this year!

Riverside Female Sitting On Nest

The Riverside female Red-tailed Hawk has begun sitting on the nest north of the Boat House Café. She was there when I arrived early this afternoon.  She left briefly to copulate with the male and then returned to the nest mid-afternoon.  The male came to nest soon after the copulation with a rodent for his mate.  She eat it and then settled down into the nest.  She most likely hasn't laid eggs just yet, but she should over the next week.

When both of them are on the nest together, there are some pictures that clearly show the female's broken beak compared to the male's.  Her beak is recovering nicely and shouldn't pose a problem for the pair.  But it's great to have some side by side comparison shots.

Lola and Pale Male

Lola is sitting on eggs, on her 5th Avenue nest.  The nest looks to be about an inch higher than last year.  A great sign the birds are responding to the renovations of the nest in 2008.  Let's wish them well this year!

I was birding in the Ramble, when I saw Pale Male circle the nest with food in his talons.  When I arrived, he had already left it on a nearby terrace and Lola and he had switched off.  He warmed the eggs while she eat.

Here are some pictures of her eating and a short movie of her return to the nest.

Madison Square Peregrine Falcons

Today one of my co-workers, called my office to tell me she could hear two Peregrine Falcons on the west side of my office building.  The falcons had already flown off by the time I got to her office, but from the east side of our office building, I was able to locate and photograph one of them high atop 41 Madison at 26th Street.

Riverside and Broadway

I spent the early afternoon looking at the Riverside Red-tailed Hawk pair on Saturday.  There nest is just off the Hudson River near 8st Street and looks great.  Last year they laid eggs around mid-March, so the female should start sitting on the nest soon.

Other nests in Manhattan are doing well.  Inwood Hill Park, Highbridge Park, St. John the Divine and 5th Avenue nests are doing fine.  The Highbridge nest is back to its old spot.

The Central Park South pair is still there but I don't have any details about their nest.  The Houston female lost her mate last year, and may be nesting on the ConEd plant around 14th Street.  The pair that was around the City College campus remains a mystery.

Sightings of hawks this winter around the north end of Riverside Park and around the Court House buildings on Center Street make these locations possibilities for new nests this year.

When leaving Riverside Park, check out the American Kestrels that have a scrape at 80th and Broadway.  One of them is usually on the building south of Zabar's or on the church at 79th and Broadway.

Saturday at Riverside, Gathering Sticks

Later in the afternoon, nest building resumed.  They both gathered sticks.  Sometimes breaking off tree branches and sometimes picking them up from the ground.  When they picked them up from the ground, they also engaged in a game of cat and mouse with the local squirrels.  They are being very industrious.  Last year, they started nesting mid-March, so they do need to get the nest finished soon.

Back To Familiar Territory At Riverside

It looks like the Riverside Red-tailed Hawk pair may be using their old nest from last summer after all.  They haven't been seen in the 90's this week, but have been building back at their old site a few blocks north of the Boat House Café.

The female was doing remodeling when I arrived late on Friday afternoon.  (Thanks to all of the Riverside birders, who emailed about the updated nest location.)
