I almost forgot another site MDOsprey birders may find interesting - The Washington DC Birdscape Project at http://www.mbr.nbs.gov/geotech/dcbirds/all2.html. I'm not sure if the maps at this site are for breeding birds. The Blackpoll Warbler page has one bird marked in the western corner of the city. -- David Gersten gerstens@erols.com Herndon, VA
