Chaco Chachalaca (Ortalis canicollis) is a declining Neotropical bird, for which our current
knowledge about its natural history is very limited. Here, we evaluated for first time the utility …

The lunar cycle is known to affect the behaviour of strictly nocturnal species, but for diurnal
species that are periodically active during the night, this has been less investigated …

Researchers studying the evolution of animal communication often ask what generates and
maintains signal complexity, but they define and measure complexity in different ways. If …

Some diurnal birds vocalize at night but the reason for this has seldom been studied. We
monitored the nocturnal vocal activity of the Undulated Tinamou Crypturellus undulatus from …

Recent studies have shown that nocturnal singing in diurnal birds is a common
phenomenon, however, the understanding of the mechanisms, functions and consequences …

Most bird species sing by day, with two distinct peaks of vocal activity—around sunrise and
sunset. However, even typically diurnal birds also sing during at night what is for them an …

Animal communication is an important aspect of ecology across taxa, and there is a growing
area of research that examines how animals plastically adjust their signals to account for …

The songs of most passerines have been well described; however, songs from some
species are more difficult to record and have yet to be characterised. The Ovenbird (Seiurus …

The study of birdsong helps with conservation strategies, the neuroscience of vocal learning,
and our understanding of communication. Many interactive singing behaviours have been …

Birds use social as well as environmental cues to inform their habitat selection decisions. By
manipulating social cues with song playbacks, biologists can influence where individuals …
