A New Method for Trapping Chimney Swifts and Other 
Vertical Hollows 
Birds That Nest in 
Hazel E. Wheeler 1 
ABSTRACT.—Previous Chimney Swift ( Chae 
pelagica) trapping efforts relied on chimney-top 
traps at large roost sites, which were disruptive 
tnefftciem when targeting individual birds. I design, 
hoop net , or use a. nest chimneys to trap indivic 
tn CnH g b n Cai A gh ' 13 Swifls " different s 
n Guelph Ontano, Canada over two summers with 
sue abandonment. This trap is superior for trapp 
individuals because it; (|, can be dep)oved ™ 
without scaling the chimney. (2) will work on chimn,

c icient. sale, and relatively simple method of trapping

Historically, Chimney Swifts (Chaetura pelu - 
gii a) were trapped mainly at chimneys where they 
toost dining spring and fall migration using a 
specialized chimney-top trap (Bowman 1952). 
iese (taps were ellective in catching large 
numbers of birds at roosts (e.g.. Peters 1937. 
Calhoun and Dickson 1942. James 1950). but their
