Cerulean Warbler

The cerulean warbler, once a common sight in the forests of the eastern United States, is vanishing at an alarming rate. Over the past four decades, the cerulean’s numbers have declined by seventy percent. Between 1966 and 1999, it declined an average of 4% per year throughout its eastern breeding range. Within the species core range (Midwest and Southeast) the total population decline is closer to eighty percent.
