This is bar-tailed #godwit SEDTSYS.
We saw it at Striep, Terschelling, Dutch Wadden Sea on Friday 23 May, and a day later she was cruising the Gulf of Finland on her way to the Taimyr tundra! The exodus of barwits from #WaddenSea is almost complete. See: www.globalflywaynetwork.org/tracks/speci...
POSTDOC VACANCY: We have a 3 year position available studying variation in population size and habitat use of red knots in the #WaddenSea. We the aim to understand bottom-up and top-down processies. More info here: workingat.nioz.nl/o/postdoc-po... #WATLAS #SIBES #ornithology #movementecology

Our milestone #SIBES publication is out! We describe methods and share data of this huge sampling effort. We hope it will stimulate research, forge collaborations, and allow evidence-based management of the UNESCO #waddensea. Read the paper here: www.nature.com/articles/s41... #macrozoobenthos
4/4 The bills of Crab Plovers and Beach Thick-knees are strikingly similar. Both are endemic to the Indo-West Pacific (IWP) and crab specialists, yet not closely related. We suggest these bills exemplify convergent evolution, shaped by the ‘escalated’ environment of the IWP. ©J vd Kam.
3/4 Only when swimming crab densities are very low, Crab Plovers will switch to forage on burrowing crabs by playing the ‘Battle of Waits’. Study conducted at Barr Al Hikman in the Sultanate of Oman.
2/4 Handling swimming crabs can be time consuming. Nevertheless, from an energy-maximization perspective we could explain why in most cases Crab Plovers prefer swimming crabs with 'vast and powerfull claws' over burrowing crabs.
WAIT A MINUTE? No way. New paper out on prey choice in the fascinating Crab Plover! We found that Crab Plovers strongly prefer feisty swimming crabs over burrow-hiding sentinel crabs. Their specialized bill enables them handle those feisty swimmers! doi.org/10.1111/eth.... @globalflyway.bsky.social
Rumex, tagged in 2022 at Schiermonnikoog (NL), decided to winter in the Tagus Estuary. As he spends most of his time at the intertidal around Sitio das Hortas, also my go-to birding spot, I've encountered him on multiple occasions in the past few weeks.
