The Sloppy AP

Lincoln called me yesterday morning while I was up at the Harlem Meer and told me he photographed a Bald Eagle with a fish in its talons flying over the park. He said it was quite high-up and he used is 400mm lens with a 2x converter. He said he was going to tell an AP reporter at work about it and asked if I would speak to the guy and give him some background.

The reporter, Richard Pile, called in the afternoon and I spoke with him for around 15 minutes. I told him Bald Eagles flying over the park were not that rare and that there was a project up in Inwood to reintroduce Bald Eagles into that park. I also pointed him to my Web site to a photo of a an adult male eagle that had flown 20-30 feet over my head at the Meer last spring.

Ben Cacace was kind enough to correct the misspelling of my last name on e-birds but I was troubled by several other errors in such a short article and wonder if this type of sloppiness is standard operating procedure at the Associated Press. I have not received a reply to my e-mail asking for an explanation.

Other errors of note:

My name is Cal Vornberger. The name of my book is "Birds of Central Park." This and the spelling of my last name could have been easily checked on my Web site. I spelled out the URL for Mr. Pile but he never asked for the spelling of my last name.

Both quotes attributed to me are paraphrases and misrepresent what I said. I said I had photographed Bald Eagles fishing off ice floes in Peekskill and very occasionally they could be seen floating down the river this far south. I also said no Bald Eagle has ever been observed perched in a tree in Central Park. I said nothing about nesting there.

Lincoln has a 400mm lens. Its focal length might be extended to 800mm with the addition of a teleconverter.

Yigal Gelb is the program director at New York City Audubon.

Famed NYC Hawk Sees Bald Eagle Soar By

Filed at 2:15 a.m. ET

NEW YORK (AP) -- Pale Male, the famed red-tailed hawk of Central Park, was perched on the 22nd floor of the swank Beresford apartment building on Wednesday when the national emblem of the United States soared past, carrying a large fish in its talons.

''Pale Male usually sits there sort of relaxed, but he sat up straight when he saw the bald eagle,'' said Lincoln Karim, the man who made Pale Male and his mate Lola famous with his extensive photographic record of the romantic raptors raising fledglings in their high-rise aerie on Manhattan's Fifth Avenue.

Karim, doing his usual morning routine of photographing Pale Male, had the hawk in his viewfinder when the bird suddenly went to attention.

''I looked up when Pale Male did and saw the eagle,'' Karim said. ''They fly over in migration season, but very high. I have never seen one that close.''

At that, the white-headed bird was distant enough that Karim, an Associated Press Television News technician, needed his 800mm lens to freeze it in flight, and all but one of his photos were slightly blurred by movement.

The photo showed the eagle as it appears on the national escutcheon -- wings spread, head cocked in vigilance, but with what looked like a striped bass in its talons, instead of the flowing ribbon reading, ''E Pluribus Unum.''

Bald eagles, once highly endangered and always strictly protected by federal law, have prospered in the New York region in recent years. As fish-eaters, they live in the Hudson River highlands, and several have been reintroduced under a city program to the Inwood section of upper Manhattan. They can be seen in winter, riding ice floes down the river and fishing along the way, said Cal Von Burger, a freelance photographer and author of a book, ''The Birds of Central Park.''

Von Burger said he has spotted eagles over the park numerous times in migrating seasons but none has chosen to live there.

''They like high perches, and the trees aren't big enough, but unlike peregrines and other falcons they don't like buildings either,'' he said.

Yigal Gelb, executive director of New York City Audubon, which protects wild birds and their habitats, said eagles were rare in the park.

''Seeing one,'' he said, ''is a pretty big deal.''

Hooded Mergansers Enjoy Crawfish

I have been photographing the Hooded Mergansers (and other waterfowl) on the Central Park Reservoir lately. What's interesting about the Hooded Mergansers is that they enjoy dining on the abundant crawfish population at the south end of the reservoir near the pumping station.

According to Peter Warney (who is an expert in such matters) these are the same crawfish enjoyed by New Orleaners in their gumbo and jambalaya. Usually crustaceans of the family Astacidae are referred to as crawfish (or crayfish). Crawfish are considered a delicacy in both Europe and America. This smaller, fresh water cousin to the lobster was no doubt introduced into Central Park's waters. A large photo of a Great Blue Heron trying unsuccessfully to eat a crawfish appears in my book, "Birds of Central Park."

The birds don't eat the whole crawfish, however. My photos reveal that they manoeuvre the crustaceans with their beaks until they have are holding their prey by the claws. They then shake their meal rapidly until the claws separate from the body and swallow only the claws. I don't know how they digest the hard outer shell but they clearly enjoy the meal. The females appear to be much more adept at catching the crustaceans than the males.

I have also observed both male and females diving for Turkey Oak acorns. Turkey Oaks surround the reservoir and the ground is littered with acorns. I've got to believe plenty fall into the water and settle on the bottom.

Last winter I observed female Wood Ducks diving for Turkey Oak acorns at the Harlem Meer.

Monk Parakeets Take Manhattan

I have been photographing the Monk Parakeet nest at 103rd and Amsterdam lately. Thanks to Bruce Yolton for telling me about it. Apparently (according to neighborhood residents) the parakeets have been building a nest under the A/C unit for about six weeks now.

Although we had a short cold snap the continuing mild weather makes it much easier for the birds to build and maintain their nest. The parakeets also seem to enjoy the abundant fruits ripening on the trees in the Fredrick Douglass complex.

They also spend a lot of time breaking branches from the neighborhood trees to use in the nest. The photo at right shows one of the parakeets sharpening the end of a stick in preperation for inserting in the nest.

My gallery has quite a few photos of these guys as I find them quite photogenic.

This info is from the Wikepedia entry on Monk Parakeets. The entry on the last paragraph about Greenwood Cemetery is particularly interesting:

The Monk Parakeet (Myiopsitta monachus), also known as the Quaker Parrot, is aspecies of parrot that originated in the temperate areas of Argentina and Brazil in South America. It is the only member of the genus Myiopsitta.

There are four subspecies:

* M. m. monachus, southeastern Brazil, Uruguay, and northeastern Argentina
* M. m. calita, western and southern Argentina
* M. m. cotorra, southeastern Bolivia, Paraguay, northern Argentina, and southern Brazil
* M. m. luchsi an isolated population in Bolivia which is smaller and may deserve species status.

This parrot is, on average, 29 cm longwith a 48 cm wingspan, and weighs 100 g. Females tend to be 10-20% smaller. It has bright green upperparts. The forehead and breast are pale grey and the rest of the underparts are very-light green to yellow. The flight feathers are dark blue, and the tail is long and tapering. The bill is orange. The call is a loud and throaty graaa or skveet. Domestic breeds have produced colors other than the natural plumage; these include white and blue in place of green.

The Monk Parakeet is the only parrot that builds a stick nest, in a tree or on a man-made structure, rather than using a hole in a tree. This gregarious species often breeds colonially, building a single large nest with separate entrances for each pair. In the wild, the colonies can become quite large, with pairs occupying separate "apartments" in nests that can reach the size of a small automobile. Their 5-12 eggs hatch in about 24 days.

Unusually for a parrot, Monk Parakeet pairs occasionally have helper individuals, often a grown offspring, which assists with feeding the young (see kin selection).

Monk Parakeets are highly intelligent, social birds. Those kept as pets routinely develop large vocabularies.

The Monk Parakeet was brought to the United States in the late 1960s as a pet. Many escaped or were intentionally released, and populations were allowed to proliferate. By the early 1970s, it was established in seven states, and by 1995 it had spread to eight more. There are now thought to be approximately 100,000 in Florida alone.

As one of the few temperate-zone parrots, the Monk Parakeet is more able than most to survive cold climates, and colonies exist as far north as New York City, Chicago and communities in coastal Rhode Island and Connecticut. This hardiness makes this species second only to the Rose-ringed Parakeet amongst parrots as a
successful introduced species.

The lifespan of Monk Parakeets has been quoted to be from 15-20 years, to 25-30 years.

In Argentina and Uruguay, Monk Parakeets are regarded as major agricultural pests (as Charles Darwin noted). In areas where they have been introduced, some fear that they will harm crops and native species. Evidence of the harm of these birds in introduced areas is disputed, and many people oppose killing a charismatic bird, but there have been local bans and eradication programs in some areas of the USA. Because of its invasive species status, a number of states outlaw either importation, sale, release , or mere possession of a monk parakeet.

Self-sustaining feral populations have been recorded in Europe, Israel, Bermuda, Puerto Rico, the Canary Islands and Japan. Outside the USA, introduced populations do not appear to raise similar controversy, presumably because of smaller numbers of birds.

In addition they have found a home within Greenwood Cemetery in Brooklyn, New York after an accidental release decades ago. While the grounds crew initially tried to destroy the unsightly nests at the entrance gate, they no longer do so, because the presence of the parrots has reduced the number of pigeons nesting within it. The management's decision was based on a comparative chemical analysis of pigeon faeces (which destroy brownstone structures) and Monk Parakeet faeces (which have no ill effect). Oddly then, the Monk Parakeets are in effect preserving this historic structure.



I found this info on the "Institute for Biological Invasions" Web site.

First recorded in New York in the late 1960s (Lever 1987, Long 1981), they became widespread in the northeast and New England states in the 1970s (Niedermeyer and Hickey 1977), but their range was dramatically reduced by the USFWS control efforts, according to CBC data from the early 1990s (Van Bael and Pruett-Jones 1996). Although they had been eradicated in New York, Connecticut, and New Jersey (Smith 1988, as cited in Stevenson and Anderson 1994), CBC data from the 1990s reveals large, stable populations of monks in these areas (Van Bael and Pruett-Jones 1996). Monks were first observed to the north in Montreal, Quebec, Canada in 1980, representing the northernmost known population of monks, and may have taken hold (Gauthier and Aubrey 1996, Spreyer and Bucher 1998).

Although monks reached and colonized numerous locations in midwest and middle Atlantic states (Neidermeyer and Hickey 1977, Long 1981), most of these populations did not exist by 1995 (Van Bael and Pruett-Jones 1996). The best studied population occurs in Hyde Park in Chicago, Illinois (Hyman and Pruett-Jones 1995, South and Pruett-Jones 2000). In April 1992, Hyman and Pruett-Jones (1995) counted 64 birds and a total of 26 nests on power poles and one antenna tower in Hyde Park, a suburb west of Chicago. After the nestlings fledged in July, they counted a total of 143 birds, and in the spring of 1993, counted a total of 95 birds in the same area (Hyman and Pruett-Jones 1995). The birds foraged on plant buds, weeds, fruits and berries of ornamental plants when available, but fed exclusively on commercial bird seed at bird feeders during the coldest months. More recently, South and Pruett-Jones (2000) made over 1,400 individual foraging observations from 300 foraging groups in the Hyde Park population. The birds fed mainly on birdseed (over 25 % of their overall diet). The plant families Poaceae and Rosaceae were represented in over 10% of the foraging observations, but monks fed on 11 other families of plants as well. Seasonal differences in diets were dramatic, with flowers and buds comprising over 80% of their diet in spring, fruits comprising over 80% of their diet in summer, and seeds comprising 100% of their diet in winter. They formed feeding groups usually of less than five birds, and the largest flock observed was 31 birds.
