LOXIA CURVIROSTRA BENTI Griscom 



Bent's Crossbill 



Habits 



Ludlow Griscom (1937) gave the above name to a crossbill which 

 occupies part of the range formerly assigned to bendirei, and which 

 he diagnosed as follows: "A relatively large crossbill, with a long and 

 relatively slender bUl; wing (male) 93.0-98; culmen 17.0-19.0; depth 

 of bUl at base 10.0-10.5. Coloration of adult male chiefly in fresh 

 fall and winter plumage strikingly rosy red, with paler and whiter 

 belly, less brownish gray; in worn breeding plumage always bright 

 scarlet. Adult female in fresh fall and winter plumage a lighter and 

 brighter yellowish below, the throat whiter and less flecked with gray, 

 more sharply contrasted with the yellowish breast; beUy whiter and 

 grayer, less brownish gray; worn breeding birds often inseparable 

 from bendirei in coloration." The type, an adult male now in the 

 Museum of Zoology of the University of Michigan, was collected at 

 Grafton, N. Dak., Oct. 8, 1931. 



Griscom assigns to it the following range: "Normal breeding area, 

 the pine hills of southeastern Montana, eastern Wyoming (Weston 

 and Crook counties), western North and South Dakota, and the 

 Rocky Mountain region of Colorado. Wandering northward to the
