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.

The dunlin is a shorebird species with an extensive distribution in the northern hemisphere. Several subspecies are known, and this blog highlights a particular one: the southern dunlin, or in fancy s...

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.

The diversity in plumage and behaviors of #ruffs is stunning and probably an underused asset for their #conservation @simonvandepitte.bsky.social #IWSG2025 #shorebirds #ornithology

Something to look for in #wader nests. Blue eggs are becoming increasingly common in #ruff clutches @jellybb.bsky.social #IWSG2025 #shorebirds #conservation

Interesting talk by @jellybb.bsky.social about the aberrant egg coloration in Ruff clutches. Blue eggs may affect nest survival, but fitness effects may be habitat dependent. @waderstudy.bsky.social IWSG Conference 2025 in Groningen (Netherlands) #IWSG2025 #waders #shorebirds

Belated but wonderful news: Kriszti Kupán has won a 3-year grant from the Bauer-Hollmann Stiftung for monitoring and developing an integrative #conservation management approach for threatened #ruffs and #dunlins at #Liminganlahti! 🥚🎉🐣

The first chapter of my thesis is out now in Journal of Ethology! Check it out if you're interested in taking a deep dive into the vibrational signal of a very cute spider 🕷️〰️

We're not really sure! Could be something from the environment? We noticed fluctuation between years/field sites in the occurrence of these blue/pale eggs which are the most odd ones..

Jelena Belojevic @jellybb.bsky.social · Jun 21

Intraclutch egg color variation in #ruffs is striking. Pale to strongly pigmented, speckled and not speckeled and even blue eggs within a single clutch 💙

Adorable #ruff chicks for your Sunday evening. Or Monday morning.

It's always nice to have back a bird you ringed!

Yesterday, we found the nest of this blonde female. Three of her eggs were also exceptionally pale. #ornithology #waders

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.

Yeah. Lapwings are quite contrasting, even in grass. But I know the struggle with plovers. Here in Finland they nest on former snow dumps and beaches too. Takes some serious pattern recognition to find them

Jelena Belojevic @jellybb.bsky.social · Jun 6

Maybe a posted the one from a rather difficult angle 😁

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 💤

Ruff clutches are expertly hidden, the eggs are camouflaged and very difficult to find. But this year’s field crew with @jellybb.bsky.social @simonvandepitte.bsky.social @koivulakari.bsky.social @vmpakanen.bsky.social is on 🔥 and found already plenty of them.
