American Crows (Corvus brachyrhynchos) are difficult to capture. I used a simple technique(box traps) to capture 151 crows incidental to my eastern coyote (Canis latrans) research at two study sites ineastern Massachusetts. Crows were captured at a higher rate during the spring (winter = 33 captures, spring = 70,summer = 22, and fall = 26). Among months, capture efficiency ranged from 0.7 in August to 8.5 in May,with an overall average of 4.1 crows captured per 100 trap days. Although other capture methods (e.g., net launchersand Australian crow traps) have been used to capture crows in greater numbers, box traps can be an importantcomplement to the other capture techniques because they are transportable, easy to use, relatively cheap, and easyto obtain.
