“…We chose the fragmented Coto Brus region, where the degree of habitat destruction (70% forest loss of the original forest cover (Zahawi, Duran, & Kormann, ) is representative for HMTLs of many Latin American regions with moderately intensive land‐use (Lindquist et al., ). Birds are crucial providers of key ecosystem functions, and their disappearance in tropical systems has been linked to pervasive reductions of ecosystem functions such as pollination, seed dispersal and herbivore control, and rapid evolutionary changes in mutualistic partners (Galetti et al., ; Hadley, Frey, Robinson, John Kress, & Betts, ; Karp et al., ; Kormann et al., ). Further, birds are highly sensitive to disturbance of native forest (Barlow et al., ; Gibson et al., ), with forest specialists and particularly forest‐dependent insectivores being among the most vulnerable organisms to forest modification (Barlow et al., ; Carrara et al., ; Gibson et al., ; Morante‐Filho et al., ; Powell, Cordeiro, & Stratford, ; Powell, Wolfe, et al., ).…”
