Abstract: | To eliminate periodic inspection of automatic live traps (which may forewarn target species and hinder capture), we incorporated 2-way radios with a conventional home-security switch to develop an inexpensive alarm-equipped bow net. We modified the call button of a 2-way radio to receive leads from a mini magnetic-reed contact switch and connected the switch to the hoop of an automatic bow net. Assembled, this system sends a radio signal from 300 to 400 m when the bow net is sprung. For 3 years in Texas, this system was effective in signaling capture of American kestrels (Falco sparverius, n=2), ferruginous pygmy owls (Glaucidium brasilianum, n=16), and loggerhead shrikes (Lanius ludovicianus, n=1) during the day and eastern screech owls (Otus asio, n=3) and ferruginous pygmy owls (n=7) at night. By adapting technology to established field techniques, researchers may increase their efficiency and hence enhance studies that influence species conservation. |
