Alarm calls, the vocalisations given during encounters with threats, vary tremendously in acoustic structure across species. Many alarm calls are structurally graded, which can convey information a...

Jane Goodall’s radical ideas that animals have individual personalities, relationships and even emotions reshaped how we understand primates. It also sparked fierce ethical debates that are still play...

An updated phylogeny of bats is presented, based on new genome assemblies and many ancient fossils and including all known bat families.

The reconstruction of ecosystem responses to past climate change has historically focused on large vertebrates. In contrast, small vertebrates with po…

Managing urban environments to foster positive coexistence between people and birds poses substantial challenges, as it requires a broad understanding…

Classic studies and recent advances in avian egg-shape recognition confirm the presence and the plasticity of a threshold-based shape-rejection mechanism across diverse species. Whether and how egg-sh...

Wild Neighbours will help readers understand the habits, personalities, quirks, ingenuity and everyday dramas of the animals and plants that live among us.

Almost all parasitic plants, including more than 3000 species, are angiosperms. The only suggested gymnosperm exception is the New Caledonian conifer, Parasitaxus ustus, which forms a bizarre graft-l....

Synopsis. The word sex can refer to at least seven distinct, evolutionarily related biological phenomena (0–6 below). Bacteria and archaea use mechanisms f

We found that red-winged blackbird parents increased aggression toward potential nest-predators as their broods aged and they adjusted their responses acco

Abstract. Some granivorous songbirds remove the hard husk of seeds before swallowing. This dehusking behaviour is a complex sensorimotor task that requires

Abstract. Parental investment can shape offspring growth, with consequences for sibling–sibling competition and survival. Altricial birds often face severe

Although bird songs are classic models for understanding the evolution of vocal communication, their global diversity has long made the development of a unifying framework challenging. By analyzing th...

Species accounts for all the birds of the world.

The right to be judged by a jury of your peers is a bedrock of American democracy. This principle applies not only to the judicial system but also to how the federal government evaluates and awards bi...

Social evolution made larval honey bees dependent on adult colony members for feeding; they are confined to cells in waxen honeycombs and visited a...

Naked mole-rat (Heterocephalus glaber) queens produce isopropyl myristate, a low-volatility ester that high-ranking animals detect and avoid, which alters prolactin and progesterone in other females t...

The 20th International Society for Behavioral Ecology (ISBE) Congress will take place at the Lingotto Conference Centre in Turin, Italy, from July 20-24, 2026, marking the first time the event is...

Andean leaf-eared mice (Phyllotis vaccarum) live at the highest elevations of any mammal, and they also have the broadest elevational range, from sea level to mountain summits of >6700 meters. Highlan...

By Véronëque Ignace, Sofia Mariyamis & 6 more. FloodNet NYC, a collaborative project, develops real-time urban flood monitoring tools and uses community engagement to make flood data accessible and ac...

Sexual dichromatism is often assumed to increase dependent offspring's depredation risk when conspicuous adults attend the den or the nest, yet empiri…

Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta-analysis, we show urban populations exhibit increased boldnes....
