A question was posed at Moreau Lake this past weekend that piqued my curiosity and inspired me to pull out a spreadsheet I made this past spring. It began out of my need to have a list of all birds I might see in all seasons in the three counties I regularly visited in upstate New York, those being Washington, Warren, and Saratoga counties. The list was first created using the DEC's Breeding Bird Atlas, then organized in taxonomic order based on the AOU list. I arbitrarily decided whether the species had a big, medium, or small population and whether it was increasing, decreasing, or staying about the same by comparing the distribution maps (1980-1985 map with 2000-2005 map). I then determined what season one would see each species by comparing range maps in 4 or 5 different field guides, including Peterson's and Sibley.
What you are about to see is the list of birds one potentially might see in Warren, Saratoga, and Washington counties in upstate NY in the winter (yes, this includes both those that are here year-round and those that migrate here in the winter months), organized by those arbitrary population sizes. The list under each population size runs by taxonomic order.
At the end you will find a heading "Not in BBA." For whatever reason, the species has inconclusive data in the DEC's Breeding Bird Atlas, thus I was unable to determine an arbitrary population size, but field guides show that the bird has a winter or year-round range in those counties of NY. Notes on the population size that I have included come from Peterson's and/or Sibley field guides.
