largest on record was in 1945-46 when the "Snowy Owl Committee" of 

 the American Ornithologists' Union received reports of 13,502 birds, 

 of which 4,443 were reported killed. It extended over the entire width 

 of the continent from Washington and British Columbia to the 

 Atlantic coast and south to Nebraska, Illinois, Indiana, Pennsyl- 

 vania, and Maryland. One was taken as far south as South Carolina. 



In the Rocky Mountain region, great flights of the beautiful 

 Bohemian waxwing are occasionally recorded. The greatest invasion 

 in the history of Colorado ornithology occurred in February 1917, 

 when it was estimated that at least 10,000 were within the corporate 

 limits of the city of Denver. The last previous occurrence of the 

 species in large numbers in that section was in 1908. 



Evening grosbeaks likewise are given to more or less wandering 

 journeys, and, curiously enough, in addition to occasional trips south 

 of their regular range, they travel east and west for considerable 

 distances. For example, grosbeaks banded at Sault Ste. Marie, 

 Michigan, have been recaptured on Cape Cod, Massachusetts, and in 

 the following season were back at the banding station. Banding 

 records and museum specimen identifications demonstrate that this 

 east-and-west trip across the northeastern part of the country is 

 sometimes made also by purple finches, red crossbills, and mourning 

 doves.
