Re: [Marxism] Red-tail hawk sighting



Does anyone know whether the presence of red-tail ("chicken") hawks
in cities is new?

Not really -- they like cities, especially dirty cities, because people's garbage attracts rats, mice and other prey. (See the Times article pasted below -- the Bronx Birding Club spotted 14 of them on a day in 1934.)

A lot of factors come into play, though. Falcon, eagle, and hawk populations were all in severe decline until the DDT ban came into effect in 1972. Now raptors are making a comeback nationwide. This is something to be kept in mind as Big Agriculture increases pressure to bring back DDT -- using yuppie hysteria over bedbugs as the thin edge of the wedge. (I guess that qualifies as relevance to Marxism.)

Just about everything I know about urban birds is due to Bob DeCandido, and extraordinarily knowledgable, personable, and entertaining naturalist who leads weekly bird walks in Central Park. It's only $5 and it's well worth it. His insights turned my 10-year-old son into a dedicated birder and fervent environmentalist.

You can find out more about him at his Web site, http://www.birdingbob.com/

I believe he's about to go on a research trip to Malaysia, so I'm not sure how many more walks are scheduled before he goes. But catch one of you can.

Bronx Club Members' Census reveals one more kind than last year

From early morning until after dusk last Sunday, twenty-nine members of the
Bronx County Bird Club, in their eleventh annual bird census, toured a roughly circular district, between the Palisades, Van Cortlandt Park, Rye and White Plains, in search of birds. Dr. Ernst Mayr, associate curator of birds at the American Museum of Natural History, compared the reports of the members and announced yesterday that ninety-seven species had been recorded, one more than last year.

Three birds were seen, he said, that had not been found on any previous census - the pigeon hawk, the clapper rail and the purple sandpiper. A purple sandpiper was seen by a party led by William Vogt of the Jones Beach Bird Sanctuary. His party had hired a boat to take a census of marine birds, fearing, as happened last year, they would miss several birds owing to fog.

In the last eleven years, Dr. Mayr said, the club has recorded in its censuses, always taken on the Sunday before Christmas, 139 species. He believed that in the next 25 years, the club might find 160 species, depending on climactic conditions.

All over the country, Dr. Mayr said, similar censuses are taken from Dec. 22 to 27. The results are sent to Dr. Frank Chapman, editor of Bird-Lore, which is published by the National Association of Audubon Societies, and the tabulations are used as an index of climatic conditions and the migration of birds. Dr. Chapman originated the first bird census in this country in 1899.
