I report a predation rate of 24 birds from 3707 total captures of birds caught in mist-nets in fragmented upland forests in Kenya. Predation was highly concentrated in specific forest fragments, with multiple birds simultaneously found killed in more than half of the predation events. Predators were probably attracted to the mist-nets by the noise and activity of the netted birds because the capture rate of predated nets was more than three times the mean for the survey as a whole. The most common victims were Yellow-whiskered Greenbuls (Andropadus latirostris), and the most common predators were blue monkeys (Cercopithecus mitis). Although 20% of all our mist-net captures were in Kakamega, a large forest, not a single bird was taken from our nets there, suggesting that predation rates on mist-netted birds are higher in small forest fragments.
