Population status

Bald Eagle
(Haliaeetus leucocephalus)

Both the Christmas Bird Count (CBC) and the Breeding Bird Survey (BBS) provide good information for this highly detectable species, although the BBS does not provide good coverage of the remote northern portion of the breeding range. Both surveys indicate that the Bald Eagle has undergone a dramatic population increase between about 1970 and 2012. The North American results of both the CBC and the BBS show a similar dramatic increase in the continental population.
