YELLOW-BELLIED FLYCATCHER. 427 



cato, and makes more or less pause after each couplet, the Yellow- 

 bellied whistles four notes, kil-lic kil-lic, with but a short pause — 

 a mere rest — between each pair, and delivers the notes with a 

 trifle less abruptness. 



Other notes of the present species resemble ^tvz ?in6. pe-we-yea. 

 These are heard when a pair are in close companionship. They 

 are soft, sweet, cooing-notes, delivered in a plaintive tone that 

 suggests the tender pathos of the Pewee's. 



Note. — The Fork-tailed Flycatcher {Mtlvulns tyrannus), 

 a bird of Central and South America, has occasionally wandered 

 north, and been taken in Mississippi, Kentucky, and New Jersey. 



Also a few examples of the Scissor-tailed Flycatcher 

 (^Milvtilus forficattis), which rarely appears north or east of Texas, 

 have been seen in Virginia, New Jersey, Connecticut, Ontario, and 

 Manitoba, and one wandered to the shores of Hudson Bay.
