General Notes

The population of Bald Eagle appears to be increasing significantly, according to a recent analysis of Christmas Bird Count and Breeding Bird Survey records conducted by National Audubon Society scientists. It is possible that the North American population has increased by as much as 780% in the last 40 years. There is sufficient data about this species to have a fairly high level of confidence in this magnitude of growth.  This is indeed good news for a species that was so drastically reduced by the effects of DDT near the middle of the last century.

Although not yet considered common in Timiskaming, the Bald Eagle is nevertheless a reliable nester in the area, with typically 15 to 20 pairs raising young successfully here in recent years.  Because it is a large, conspicuous bird, and as an adult is readily identified by even the most casual bird watcher, observations of this species are reported frequently.  Increases in the local breeding population have been apparent in recent years. Increased numbers are also usually observed in Timiskaming during both spring and fall migration periods, when breeders from farther north are passing through.
