YELLOW-BELLIED FLYCATCHER. 427 
cato, and makes more or less pause after each couplet, the Yellow- 
bellied whistles four notes, 22/-léc Rzl-/ic, with but a short pause — 
a mere vest — between each pair, and delivers the notes with a 
trifle less abruptness. 
Other notes of the present species resemble gea and fe-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 ForRK-TAILED FLYCATCHER (Milvulus 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 
(Milvulus forficatus), 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.
