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.
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 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.
Over the past two weeks, I’ve been unable to make it into the park after work before it gets dark, and certainly won’t be able to now that we’re on standard time. So, I wanted everyone to know that this blog is only going to have weekend updates until late winter.
Other than it getting dark so early, late fall is an interesting time in the park. The fall migration is ending, but there are still plenty of things to discover including interesting waterfowl and raptors.
A pair of swans are on the Lake, lots of uncommon Central Park birds are on the Reservoir including a Pied-billed Grebe, Wood Duck, Ring-necked Duck and Hooded Mergansers. Raptors continue to migrate south over the park with sightings of Osprey, Cooper’s Hawks, Eagles and Turkey Vultures.
The leaves have turned to wonderful colors over the past few weeks. If you have a chance, take a walk in the park before it’s too late.
Below are pictures of a Pied-billed Grebe from Saturday on the Reservoir.
I’m out in California for a family wedding. These hummingbirds are from the garden of my hotel.
Lola and Pale Male were both in a tree on the east side of the Great Lawn when I arrived in the afternoon.
