Population Regulation of Black-throated Blue Warblers
January 1, 2003 by Gregory Gough
Intensive and long-term studies of black-throated blue warblers at the Hubbard Brook Experimental Forest in New Hampshire reveal a fairly stable population . What keeps them from becoming too numerous or helping them become numerous after a lean year, is of interest to scientists studying how populations regulate themselves and has long-term implications with regard to climate change and habitat destruction.
The study was begun in 1969 and continues to the present. Such long-term data studies on birds are rare but useful for understanding population changes.
