The Yellow WatchList species was Wood Thrush, which was observed 21 times at 17 point counts. Both of these species are believed to be declining, although theirpopulations are in the millions in North America. Wilson's Snipe is legally hunted in New York State....
In this paper we explore relationships between bird species richness and environmental factors in New York State, focusing particularly on how spatial scale, autocorrelation and nonstationarity affect these relationships. We used spatial statistics, Getis-Ord Gi*(d), to investigate how spatial scale aff...
Males did not mimic the most common species in their general environment, but neither did they mimic rare species. Instead, males imitated the mobbing-alarm calls of heterospecific birds that foraged on or near the forest floor. Indeed, males primarily mimicked the alarm calls of heterospecific...
The majority of bird species in the U.S. face a grim future in coming decades if environmental efforts are not implemented on a larger scale.

The steep decline in the number of species from Tropic to Pole may possibly be explained by 'the weather', that is, the latitudinal decline in the input of solar energy. This explanation, often obvious to the lay person, is dismissed or even ignored by m
Birdsong serves to attract mates and to deter territorial rivals. Even though song is not restricted to males, this dual function has almost exclusively be
