Ecology and Behaviour

Discover how birds interact with their environment and each other. This section explores habitat use, feeding strategies, social structures, breeding systems, migration patterns, and vocal communication. From territorial disputes to cooperative parenting, Ecology and Behaviour reveal the intricate ways birds adapt, survive, and thrive in a changing world. Photo by Dave Katz @tenacityinpursuit

Sound-based surveys uncover fine-scale habitat selection in the declining Crested Tit

New research from Finland suggests that Crested Tits respond more to fine-scale forest structure than to forest age in early spring, challenging assumptions about how habitat quality is defined in managed boreal forests.

Choosing Survival: Habitat Shifts in Wintering Taiga Bean Geese
Winter landscapes can appear rich in food, yet a few degrees below zero can render familiar feeding grounds unusable. For Taiga Bean Geese, survival depends on recognising when to abandon frozen pastures and seek alternative refuges. © Lars Petersson

Choosing Survival: Habitat Shifts in Wintering Taiga Bean Geese

When frost locks grasslands out of reach, Taiga Bean Geese turn to winter cereal fields to survive. New research shows how these fields become lifelines during the coldest days of winter.

The Sanctuary in the Sidewalk: Trees Rescue Birds in Mexico’s Cities

Even in the heart of a city, a tree can be a sanctuary for birds. A new study from Mexico reveals that urban trees do far more than provide shade – they offer critical nesting and foraging habitats for native species under pressure from habitat loss elsewhere.

From Movement to Meaning: A New Era in Bird Tracking
Black-tailed Godwits (Limosa limosa limosa) are among Europe’s most intensively tracked migratory shorebirds. Long-term monitoring has provided critical insights into their migration strategies, site fidelity, and survival – making them emblematic of longitudinal studies in avian ecology. © Attila Szilágyi

From Movement to Meaning: A New Era in Bird Tracking

For decades, tracking devices have told us where birds go. Now, researchers are asking an even more intriguing question: what happens to the birds we track along the way?
