Migration has died down. The birds have arrived at their destinations, and are spending their time and energy raising a new generation. But where were all those birds headed, anyway? Most went north, far north. The Boreal Forest in the Northern U.S. and Canada is essential breeding territory for many species of birds.
One familiar bird impacted by the fate of our forests is the Evening Grosbeak. Evening Grosbeaks are birds of boreal and montane forests and are therefore susceptible to all the incursions into those habitats. Chemical control of spruce budworm and other tree pests lowers this species’ food supply and may also cause secondary poisoning. Competition and the spread of disease among house finches, goldfinches, and other feeder birds may also be playing a role in the decline. Finally, populations are affected by fluctuations in insect populations and the frequency and intensity of forest fires.
Federal and state legislations promoting sustainable forest management will help fight habitat loss from inappropriate logging, mining, and drilling. Become educated about the issues and write those legislators who are most likely to make critical decisions. The informative article in the Sept./Oct.,2008 issue of Aikorns is a good place to start.
