BLUE GROSBEAK 



The line dividing their summer ranges agrees approximately with the 

 eastern border of the Great Plains. The following migration rates refer to the 

 Eastern Blue Grosbeak, as well as to the Western Blue Grosbeak. Both 

 forms pass the winter in Central America. In migrating northward, most of 

 the birds that are to summer in the eastern United States avoid the West 

 Indies and southern Florida, and fly across the Gulf of Mexico to its northern 

 shore.
