Conservation of VT's Common Terns, Part 1

Created for academic purposes as part of the Vermont Institute of Natural Science Environmental Science Research Fellowship, 2008.

The first segment of this film outlines Audubon Vermont's Common Tern Recovery Project, highlighting different conservation techniques used to increase Lake Champlain's population of this state-endangered seabird.

The second part of this film discusses nocturnal surveillance footage captured in the 2008 breeding season, including a predation event in which a Black-Crowned Night Heron (Nycticorax nycticorax)consumes 5 young tern chicks.

NOTE: Due to size limitations, this film's segment breaks do not align with the YouTube files.
