There are seven types of grosbeaks; the Black-headed Grosbeak, Blue Grosbeak, Crimson-collared Grosbeak, Evening Grosbeak, Pine Grosbeak, Rose-breasted Grosbeak and the Yellow Grosbeak. The names of the birds reflect their colours, from a reddish-purple to bright red, banana-yellow to gold and bluish-black to navy blue. These birds have some of the most beautiful colours of all the birds of North America.
The Crimson-collared Grosbeak and Yellow Grosbeak are found mostly in Mexico, the Blue Grosbeak in the central regions of the United States to Central America and the Black-headed Grosbeak in the western regions of North America as opposed to the Rose-breasted Grosbeak in the eastern regions. The Pine Grosbeak prefers northern Canada and is known to visit central North America when food is scarce. Lastly, the Evening Grosbeak, who prefers the conifer regions of Canada and migrates as far as central North America, when searching for food supplies, especially when the local food is running thin.
Their name comes from the fact that they have large bills. Grosbeaks are birds found most often in conifer and deciduous forests in North America. Their diet consists of seeds and fruit depending on the time of year.
Avibase - the world bird database This site provides the user with a complete list of bird species, broken down per country, or in the example of the US or Canada, per state and province. Here, bird species names are available in other languages, a great asset to be used as a translation of foreign bird names.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
I hope you will take advantage of these suggested websites. I have used each of them, in one way or another, throughout the years in my quest to better identify and understand our fine feathered friends.
