There was an exceptionally large flight of songbirds down the Hudson River corridor last night. An acoustic station southeast of Albany detected 4000+ flight calls of migrant warblers. This is the fourth year of monitoring fall flight calling from this location atop the Columbia Land Conservancy building in downtown Chatham, NY. During this period there have been 6 nights with 2000+ calls, 3 nights with 3000+ calls, and last night was the first with 4000+. http://oldbird.org/Data/2015/CLC/ColumbiaLC.htm
There is no indication the calling was exacerbated due to disorientation by artificial light -- it appeared to be just one and sometimes two calls per individual passing over. This suggests an unusually large pulse of migrants today in the NYC area, 100 miles to the south.
