The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Understanding how and why behavioral traits diversify during the course of evolution is a
longstanding goal of organismal biologists. Historically, this topic is examined from an …

Abstract “Diversity” is an apt descriptor of the research career of Jack Pettigrew as it ranged
from the study of trees, to clinical conditions, to sensory neuroscience. Within sensory …

Highlights•Chimpanzees produce low-frequency sounds by drumming on buttress roots of
trees.•Drumming is used across contexts with apparently long-and short-distance functions.• …

Phenotypic characters with a complex physical basis may have a correspondingly complex
evolutionary history. Males in the “bee” hummingbird clade court females with sound from …

Gharials (Gavialis gangeticus) produce a sudden, high amplitude, pulsatile, underwater
sound called a POP. In this study, gharial POPs ranged from 9 to 55 ms, and were clearly …

Motion-induced sound is an intrinsic byproduct of essentially all animal behavior.
Locomotion-induced sounds that have evolved specialization for communication are termed …

Physiology's role in speciation is poorly understood. Motor systems, for example, are widely
thought to shape this process because they can potentiate or constrain the evolution of key …

Acoustic signals that reliably indicate body size, which usually determines competitive
ability, are of particular interest for understanding how animals assess rivals and choose …

Highlights•Harbour seals perform percussive behaviour, ie flipper slap**, on land and in
water.•Rhythmic percussive signalling occurs in agonistic interactions and display …
