Hawaii Island forest bird phenology and morphometrics from 1994 to 2020
We examined data from multiple studies (1994-2020) conducted across the avian annual cycle, from multiple locations, to evaluate molt patterns and establish criteria for assignment of age and sex based on the WRP (Wolfe-Ryder-Pyle) method, or molt-cycle age classification system designed specifically for tropical species. In addition, we describe the phenologies of molt and breeding and quantify the differences in males and females based on plumage coloration and morphometrics for eight native species.This data release includes two tabular datasets, one containing breeding phenological data and the other containing morphometric data. The phenological data presents information of active breeding condition in birds (presence of an enlarged cloacal protuberance in males, presence of a brood patch in females), and whether birds were actively molting flight feathers. The morphometric data consists of measurements of birds including wing length, bill length, and mass.
