There is little information on the behavior of Short-tailed Woodstar. This species forages and perches at all heights, from low to high (Parker et al. 1996), but most frequently is low near the ground (Ridgely and Greenfield 2001b).


There is no information on territoriality or home range size in Short-tailed Woodstar.

Sexual Behavior

Little information. Short-tailed Woodstar presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509). The male performs a U-shaped courtship flight: "From a perch on an exposed twig they shot up obliquely for about 100 feet [30.5 m], swung round and plunged down at an angle to another perch" (Marchant 1960).

Social and interspecific behavior

Short-tailed Woodstar usually is solitary, as is typical of hummingbirds.


No documented reports of predation on Short-tailed Woodstar?
