Eurilaimo verde

Calyptomena viridis

Uccello verde luminoso con una forma della testa stranamente a ombrello, trovato nelle foreste di pianura. Il maschio ha barre alari nere e una “virgola” scura dietro l'occhio. La femmina è di un verde più pallido e complessivamente più semplice, senza marcature scure. Nel Borneo, si sovrappone agli Eurilaimi di Hose e di Whitehead, entrambi i quali tendono a trovarsi ad altitudini più elevate. Nell'Eurilaimo verde, si noti l'assenza di nero nelle femmine in qualsiasi piumaggio, le barre chiare sulle ali anziché macchie, e le dimensioni complessivamente maggiori. Emette note di richiamo soffici e rimbalzanti, spesso in serie.

Identificazione

The bird is about 17 cm long, plumaged in brilliant green with a black ear patch, widely gaped bill, rounded head, short tail and three black bars on each wing. The beak itself is very weak and almost hidden by the crest above it. Both sexes are similar. The female is duller and has no black markings on its ear patch and wing coverts.

Tassonomia

There are three subspecies recognized:<p>Prior to revisions by the International Ornithological Congress in 2022, the mainland subspecies went by the name caudacuta, while viridis referred to the Greater Sundaic subspecies. Based on several previous studies finding problems with this nomenclature, the International Ornithological Congress replaced caudacuta with viridis, while gloriosa replaced the former viridis.

Resident species

Comportamento

It is often overlooked, as it sits motionless inside the canopy or just below, quickly flying to a new location if disturbed. Its foliage-green color provides excellent camouflage.<p>It feeds largely on soft figs. The broadbill's feeding habits helps to distribute the seeds of the fig around the forest floor. The female usually lays between two and three whitish eggs, and the young fledge after twenty-two to twenty-three days.

Conservazione

Although this species remains common in many parts of its large range, it is considered Near Threatened as it is sensitive to habitat loss and degradation, which are likely to be causing population declines throughout its range.Due to continuing habitat loss, the green broadbill is evaluated as Near Threatened on the IUCN Red List of Threatened Species.
