We quantified eye size using two sources. For 80% of the species (N = 192) we passively captured birds using mist nets at sites located within cloud forest tracts and regenerating second growth. One observer (IJA) used calipers to measure lateral eye width to the nearest 1.1mm. We compared our field measurements to published measurements of traverse eye diameter from preserved specimens for a subset of species (N =78; Ritland 1982) and found the two metrics to be highly correlated (r = 0.92, P
