Sampling comments: "Two times before the hurricanes and four times after- ward, understory forest birds were captured using mist nets (12 m in length, 2 m height, and 32 mm mesh size) in six sites (>500 m apart) within the area covered by semi-deciduous tropical forest... In each site, mist nets were placed along three parallel 72m long transects (3 x 72 m); distance between adjacent lines at each site varied between 13 and 29 m... During each of the six sampling periods, each site was sampled over 4 consecutive days. The first half of the three transects (3 x 36 m) were sampled simultaneously using a total of nine nets, during 2 days. Then, the nine nets were moved to the second half of the three transects for 2 more days of sampling. Nets were opened at sunrise and remained open for 6 hours... Sampling effort per site was 216 net hours in each sampling period"
sampling was during northern summer 2004, winter 2005, winter 2006, summer 2006, winter 2007, and summer 2007
