Tracked for the First Time: How Juvenile Egrets Disperse Across Australia – and Beyond

A pioneering study uses GPS telemetry to map the early dispersal of great and plumed egrets from the Macquarie Marshes, revealing striking differences in their movement strategies and vital clues for wetland conservation.

Same Species, Different Clocks: Migration That Shapes Reproductive Timing in Birds

Why do some birds get ready to breed while others are still preparing to migrate—despite living in the same place? The answer lies in how they sense time.

The Extreme Breeding Ecology of Cliff-nesting Swifts

Cliff-nesting swifts defy gravity – and ecological convention. This article explores how these aerial specialists adapted to breed in some of the planet’s most inhospitable vertical landscapes.

Born in Isolation: The Australian Origin of Songbirds

Oscines – true songbirds – make up nearly half of all bird species alive today. A new study confirms that their evolutionary roots trace back to Australia, offering powerful new insight into one of the greatest radiations in avian history.

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?
