Five Red-tailed Hawk Saturday

On Saturday, I had a slow start.  I started in the Ramble trying to chase down the White-crowned Sparrow without much luck.  I then walked to Turtle Pond and found a cute group of Buffleheads among some Mallards and Northern Shovelers. 

Then I saw a hawk flying south of the Beresford.  It was Lola, the Fifth Avenue female.
She landed on a water tower on south side of West 77th Street.  The building is just west of the New York Historical Society.  After about 15 minutes, she flew due east.
I thought she had gone to the Model Boat Pond, so I walked there.  When I arrived I saw that Pale Male was on a building two blocks south of the nest location.  (Lola may have stopped in the Ramble for a late lunch.)
Pale Male posed for pictures and then flew off towards the Met.
It was such a nice day, I thought I would look to see what the Central Park South hawks were up to.  Charlotte was on the Essex House sign.
The nest still looks to be in good shape.
The Essex House boiler could use an overhaul.
Soon Charlotte went NW and circled around and then above the Trump International Hotel and Tower.
Then she landed on the top of a construction crane on a new building being built on Central Park West between 61st and 62nd.
Junior soon joined her.  If I got it right, she’s on the top and he’s below her.

Having seen four of the six building-breeding Manhattan Red-tailed Hawks, I went up to the Cathedral Church of St. John the Divine.  My luck ran out, as I was only able to see the male of the Cathedral pair.  However, five out of six isn’t that bad!
The Cathedral nest looked to be in good condition as well.

Friday in the Park

I made it to the park on Friday!  Finally, a sunny day where I didn’t have to work. I spent a few hours trying to photograph a White-crowned Sparrow without success.  I did see it a few times, but just as I tried to take a picture it would be scared off by a passing tourist.

Lola spent at least an hour in the afternoon on the NE tower of the Beresford.

Mute swans arrived on The Lake a few weeks ago.  They are very good at getting food from tourists.  I wonder if they spend the summer on an urban lake in Canada?

Fall Owls

On Saturday, the first owl of the fall season was spotted in Central Park, a Long-eared Owl (LEOW).   (I was working, so I didn’t get to photograph LEO.)

I did make it the park around dusk to look for Eastern Screech Owls (ESOW).  Unfortunately, I suspect that there may no longer be any surviving ESOs in the park. These owls were reintroduced to the park in 1998 and 2001-2002 and have not been fairing well.  Screech Owls fly at low heights and easily run into cars.  (The original decline in Eastern Screech Owls occurred about the same time as the carriage paths in the park were turned into roadways.)

I suspect the fall owl season will consist of viewing migrating Long-eared and Northern Saw-whet Owls, and confirming the disappearance of the Eastern Screech Owl from Central Park.

December Update: At least two Eastern Screech Owls are in the North Woods!  I’m happy to be wrong!

Marathon Sunday

On Marathon Sunday, I came into a park full of runners.  The marathon route goes right through Pale Male and Lola’s territory.

I walked around the Great Lawn and saw a hawk skim just above ground level from the center of the lawn to the eastern edge.  The hawk grabbed a small bird and then jumped into a low branch of a small tree between two baseball diamonds.  The bird was the immature hawk that Lola has been tolerating and to some observers, has even been playing with.

Note the immature’s stripped tail rather than a mature’s solid red tail.
The immature also has a very light eye color, which will darken over time.
Just after the immature Red-tailed Hawk finished eating, Pale Male came in to chase it away.
Pale Male landed in a tree on the west side of the Great Lawn and the immature hawk went northwest out of sight.

After looking for the immature hawks perch without success, I returned to the Great Lawn to discover Pale Male had moved to the East Pinetum.
Were he settled into a tree that was to be his roost for the evening.

Late Saturday Afternoon with Pale Male and Lola

There’s no doubt fall has arrived in New York.  It was in the low 40’s, the leaves have turned to wonderful fall colors.  Another sign of fall has arrived is the return of Buffleheads to the Reservoir.

After visiting the Reservoir, I walked south and ran into Pale Male on the Northwest corner of the Met.  Is he trying to avoid being seem on the surveillance cameras?
After about twenty minutes he moved about 20 feet, so he would have a good view of an area alongside the transverse, where there are rodents.  The cold weather had him fluffed up to stay warm.
After about twenty minutes, he flew off the Met and caught a mouse.  He flew 200 feet to catch his prey.  He must have incredible vision.
After eating, he went back to the Met.
Lola went up 5th Avenue…
…landing on a building around 88th Street and 5th Avenue.
Pale Male left the Met and looked to settling in for the night.
Lola moved to a building two blocks south of where she was…
…and then she flew east.
Pale Male followed.  We lost her, but found his roost for the evening in the East Pinetum.
As I let the park, there was a full moon in a clear, crisp fall sky.

Introduction

After all of the problems with the West Side Screech-Owls in the Spring of 2006, I wasn’t optimistic that there were any surviving Screech-Owls in the park.  Around Thanksgiving, after the leaves had fallen from the trees, I searched all of the known Screech-Owl cavities near the Rambles and in the North Woods.

I had no luck finding any owls, and even wrote in my blog, that I though 2006 might be the last year Screech-Owls were seen in Central Park.

In December, I received a note from Christine (Chris), who walks her wonderful dog Fig, in the Northwest of the park every evening that she had seen Screech-Owls.   I spent a few evenings looking for them without any luck.

In early March, I received emails detailing two different rescues of Screech-Owl babies up north.  Again, I went up to look and found nothing.

In late March, Chris wrote us again saying she had found the owls. What was wonderful, was that she had not only found the parents, but also a fledgling.  Luckily, the next day, I got to see and begun studying the Screech-Owls.

What follows is my account of the adventures and discoveries watching these three Eastern-Screech Owls in the Spring of 2007.

These photographs were all taken with natural light.  Advances in
digital photography make it possible to take pictures in very low
light.  The photographs were taken with a 500mm lens at
distances of 25-200 feet. 

The long exposures also brighten up the dark sky, so that it appears to
be daylight.  However, most of these pictures were taken after dusk.

As the nights darkened, natural light sometimes was replaced by
orange street lamps and green and red traffic signals.  You’ll notice some color shifts in the
photographs or blurry images.  To have avoided this completely, I would have needed to
use flash.  I decided that I would rather have the color shifts than
risk disturbing the owls with repeated flashes. 

I don’t think limited use of flash has any effect on the owls, but since this was part of a long term study, I wanted to be extra careful.  It’s also important to say how much flash photography disturbs the ambiance and those watching with you.  When I go birding, if I see a someone or a group watching a bird, I slowly join them before taking pictures.  Nature photographers in Central Park should take the same approach, and ask their fellow birders if they mind them taking flash pictures.  These birds don’t deserve an aggressive "paparazzi" style photo shoot.

For background on the Eastern Screech-Owl, there is basic information on The Owl Pages or the University of Michigan Museum of Zoology’s Animal Diversity Web.
