Sampling comments: "We used mist nets of 12.0 × 2.4 m (four shelves, 36 mm mesh) set up in 12 sites, suspended at seven heights... we used a maximum of two VM nets in the same rope system per sampling site... The nets were opened immediately after dawn, sampling daily 8-11 hours... The captures were carried out between July and September 2005, and summed 419 net-hours at each one of the seven sampled levels (total 2931 net-hours)" (i.e., approximately 308.5263 net days)
