Incidental captures of birds in small‐mammal traps: a cautionary note for interdisciplinary studies

摘要: Abstract Although benefits of interdisciplinary studies are numerous, potential exists for data acquisition some aspects such to impact other aspects. This may be particularly true in involving both trapping small mammals and assessment bird populations. We summarize the incidence birds captured during 8 research projects Massachusetts, Oregon, Washington that used 5 types small-mammal traps, discuss possible impacts on surveys mitigation measures. In these studies, 867 representing 17 species were 703,138 total trap-nights (TN). The song sparrow (Melospiza melodia), spotted towhee (Pipilo maculatus), Steller’s jay (Cyanocitta stelleri), gray (Perisoreus canadensis) accounted 86% all captures; ground-foraging 54% captures. Relatively high capture rates observed Sherman (H. B. Traps, Inc., Tallahassee, Flor.) an...
