Instinct vs. Experience: Steppe Eagles Learn to Migrate Safely

A new study shows that young Steppe Eagles are drawn to human-altered landscapes during migration, while adults avoid them – revealing how instinct, experience, and learning shape survival strategies in an endangered raptor.

Six Years After First Breeding, Alpine Swifts Are Colonising Hungary
The Alpine Swift was considered a rare visitor to Hungary until breeding was first confirmed in 2020. Six years later, it is breeding in several Hungarian cities, and its numbers continue to grow. / El vencejo real se consideraba un visitante raro en Hungría hasta que se confirmó por primera vez su reproducción en 2020.

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?

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.
