Productivity and foraging ecology of breeding Rusty Blackbirds on the Copper River Delta, Alaska

October 2009 - December 2012


Participating Agencies

  • USFS Pacific Northwest Research Station
  • Alaska Department of Fish and Game

The Rusty Blackbird (Euphagus carolinus) has been identified as a high priority for conservation because of apparent steep populaton declines observed since the 1960's. Until recently, this species has been poorly studied and much information is lacking regarding basic biology. This study is being conducted on the Gult of Alaska coast (i.e., Copper River Delta) and is part of a multi-site project investigating the basic breeding ecology of this species in Alaska. In addition documenting breeding habitat use and monitoring reproductive success, we are attempting to gain some basic knowledge about the diet of this species while on the breeding ground and how aquatic invertebrate resources in the Delta may impact blackbird productivity.
