BandingPOPd: Software to investigate the USGS bald eagle banding and encounter data in the Northeast United States

Other Titles


Bald eagle populations rebounded in the Northeast United States (NE) in recent decades, but it was unclear whether the rebounding population was due to in-situ reproduction and growth, from asymmetric dispersal, or both? This software was used in conjunction with independently collected encounter and banding data from the USGS Patuxent Bird Banding Laboratory to identify whether dispersal of breeding age bald eagles was asymmetric in the NE between 1990 and 2018. We define the NE as the states of Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, and Vermont.

The data consists of the banding and encounter records for bald eagles in the Northeast United States and Canada, which was originally collected by the United States Geological Survey Patuxent Banding Laboratory for their own purposes, then shared with our study by our request for our analysis. The Raw Data may be attained directly from the Patuxent Wildlife Research Center and Bird Banding Laboratory; see details in the readme documentation.
