Hello Bluesky👋! I am a PhD student working on behavior, ecology, and conservation of Ruffs and one of the most endangered wader - Southern dunlin. This year I worked with an enthusiastic young biologist and photographer Simon. Read more about our small scale dunlin headstarting project on his blog.

Our new paper on Bateman gradients in black coucals and white-browed coucals is out. Females of both species outperform males in mating and reproductive success - confirming the generality of Bateman's principle when sex roles differ.

Sex-role reversal and the Bateman gradient in coucals—females benefit from mating with multiple partners
Abstract. Conventional sex roles imply that males compete more vigorously with each other for fertilizations, whereas females are more selective in choosin

Victoria’s riflebirds are masters of time, accelerating their dance tempo by reducing the durations between movements by just 50 milliseconds, before leveling off at 3 alternations per second and flashing their yellow mouth.

Ruff lekking: The co-display of a pale satellite and a court-defending independent morph increases male attractiveness. Lekking began here (65°N) in the first week of May and continues, even though most females are already incubating and the first chicks are expected to hatch any day now.

A female Ruff enters her nest — a tent-like shelter hiding her precious eggs. She’s unringed for now, but she’ll receive her bands once the chicks hatch. #waders #ornithology

This year we spent long (and cold) nights out to capture #ruffs during peak #lekking. Each one ringed and fitted with a transmitter to help us track their movements and behavior.
Thanks to the team for the effort and stamina it takes to pull this off 💤
