Chesapeake Bay Bald Eagle Nesting Survey

Metadata Updated: December 11, 2017

The Chesapeake Bay population of breeding bald eagles increased dramatically in 1981 in not only the number of breeding pairs but in the number of nests hatching young and in the number of young hatched. The accompanying Table compares figures for this year with previous years. The 1936 data was collected by Bryant Tyrrell for the National Audubon Society. The data he obtained in that pre-DDT year is considered to represent the base line or norm: he recorded a hatch rate of 1.36 eaglets per active nest found. The first year of our current annual survey was 1962 in which we recorded a hatch rate of only 0.16 young per active nest found. This rate has slowly improved to 0.37 in 1970, in 1973, 0.91 in 1977 and now, in 1981, we have a near normal rate of 1.03 young per active nest.
