ID tip
The young Sunda frogmouth is covered in down. There are two successive downy plumages, which characterizes more primitive birds. The first down is much shorter than the second down. The second down occurs on the 7th day and the juvenile plumage comes in around 3 to 4 weeks. This plumage is a softer and looser texture with more pointed primary feathers. Within a few weeks of fledging, the first adult plumage comes in. The frogmouth has one moult per year. The Sunda frogmouth has a round tail with a centrifugal moult, meaning it moults from the inside out. Voice: The analysis of sonograms is the best way to identify frogmouth species. The calls make a "gwaa" noise. The females will make the main territorial call. The other main vocalization from frogmouths is hissing during defence behavior.

About the Sunda Frogmouth
The Sunda frogmouth is a medium-sized, old world species of bird within the order Podargiformes. It is also uncommonly referred to as the long-tailed frogmouth or the horned frogmouth. The term "Sunda" is based on the geographical range of the species to regions around the Sunda islands. The genus name, Batrachostomus, is a Greek translation to 'frogmouth', which comes from the wide shape of the bill and slight gape. The species name cornutus is a Latin word translated to "having horns", referring to the tufts of feathers on the head.
