What Do Shearwaters Eat? Uncovering a Mediterranean Food Web

DNA metabarcoding and stable isotope analysis reveal how two Mediterranean shearwaters share the same prey — and what that overlap tells us about life in a changing marine ecosystem.

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

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.

When Can a Bird Afford to Moult?
Common Bulbuls can breed year-round, yet their moult remains strongly seasonal and responsive to body condition and diet. / Los bulbules naranjeros pueden reproducirse durante todo el año, pero su muda sigue siendo marcadamente estacional y responde a la condición corporal y a la dieta. © Jeff Maw

When Can a Bird Afford to Moult?

In Common Bulbuls, the conditions associated with starting moult differ from those associated with completing it quickly. An experiment in Nigeria shows how body condition and diet shape different stages of feather replacement.

Do GPS Tags Affect Small Shorebirds?

Do GPS Tags Affect Small Shorebirds?

Solar-powered GPS tags are opening new possibilities in shorebird research — but how close are we to the limits of what small birds can carry without consequence?

The Art of Recognition: Firefinch Reframes the Path to Becoming an Ornithologist
Unlike photography, illustration allows repeated field impressions to be compressed into a single scene — combining posture, behaviour, habitat, and the way a species is most often remembered by observers in the field.

The Art of Recognition: Firefinch Reframes the Path to Becoming an Ornithologist

Birding apps usually promise speed, certainty, and instant answers. Firefinch moves in another direction entirely – towards attention, illustration, and the slower process of learning how to truly recognise birds.

World Curlew Day: The Long Decline of Curlews, Now Fully Understood

Curlews are not disappearing unnoticed. The causes of their decline are now well understood, yet across flyways and landscapes, recovery remains limited and uneven — raising a harder question about the scale and persistence of our response.
