PINE GROSBEAK 



The northern parts of both hemispheres are inhabited by the Pine Grosbeak. 

 The American birds have been subdivided into five forms, four of which inhabit 

 respectively the Rocky Mountains, the California Mountains, the mountains 

 from Alaska to Washington, and the coast district of Alaska. The other 

 form nests locally in much of Canada east of the Rocky Mountains, south to 

 Maine and the higher mountains of New Hampshire. This form, Pinicola 

 enucleator Iciicura, is the only one that performs long migrations, and the data 

 in the following tables refer exclusively to individuals of this sub-species. 

 During the winter season the Pine Grosbeak irregularly invades the northern 

 United States, and has been recorded as far south as Iowa, Kentucky, and the 

 District of Columbia.
