Mr. Lusk, who found the sulphur-bellied flycatcher in Arizona, 
states that they frequent streams bordered with large trees. “ The 
width and size of their bills, together with their short necks,” he 
says, “ gives them a peculiar appearance even at a distance.” Mr. 
O. W. Howard found the birds very quiet during the breeding sea¬ 
son, but bold and noisy afterwards. He compares their notes to the 
squeaking of a wheelbarrow.
