Vocal Behavior and Reproductive 
Strategies in a Tropical Duet-
ting Wren, ~tb~I~ 
.n.i.&r.i.s;R~.i.l.l.l!Jl. 
Abstract: Vocal duetting has been 
reported to occur in over 200 
species of birds. This behavior 
is generally assumed to be the 
result of a cooperative effort, 
serving similar functions for 
males and females. However, ob-
servational data and results of 
playback, removal, and muting ex-
periment s on bay wrens indicate 
that. in this species. duets are 
the result of differing male and 
fem a l e reproductive strategies 
s u c h that female son g s function in 
female-female aggression and males 
sing t o ac ousti c all y g uard their 
mates .
