Summer 2012: Bird Banding

This summer’s bird breeding study included bird banding.     A total of 116 Wilson’s Plover chicks and 57 Least Tern chicks were banded.    Color bands were organized to create an individual banding combination for each chick.  Wilson’s Plover (WIPL) were only banded with color Darvic bands and Least Tern (LETE) were banded with both color Darvic bands and metal bands.
