hello wonderful network, especially all of you in the #Doñana region - we are looking for someone who could check the island specified in Sandra's thread for a GPS logger and gull-billed tern chick that has died on an island in this area. please share in your networks to multiply our chances

Strong winds resulted in flooding of the last remaining #ruff clutches that were close to hatching at Bothnian Bay. A week earlier and the consequences would have been catastrophic. Flood risk increases with climate change and is a concern for Baltic #waders: www.sciencedirect.com/science/arti...

#NewPaperAlert! This one has a massive author list and has been a LONG time in coming, but is SO COOL! First, check out the first figure to get you interested! Manakins! Fruit! Sexual-selection in action (displays and Z:A chromosomal diversity)! Read on for the back story & link 1/n
above: montage of brightly coloured tropical birds, some in interesting display postures, some eating fruit
below: a phylogeny that includes those same taxa (and others) and a plot of the ratio of genetic diversity on the autosomes relative to the Z chromosomes

This season we introduced thermal drones into our fieldwork to find and monitor #ruff and #dunlin nests at #Liminka Bay. It has been a relevation, so far we found twice the number of #ruff nests in a third of the time! For the privileged drone pilots, fieldwork is now done from a comfortable chair!

#Wader breeding season on Baltic coastal meadows at Liminka Bay 🇫🇮. We have found record numbers of #ruff clutches this year. Many any of them contain again one or more blue eggs. Fortunately, current predation rates are very low 🤞 #ornithology #eggblue

Perfect timing for this picture. Ruff lekking is in full swing with their stunning display garnering a lot of attention (not only from ruff females). Unfortunately, ruffs have gone missing from many places across Europe as their breeding habitat, coastal meadows, are vanishing.

Who benefits from mating with multiple partners? Darwin suspected that in some cases, it may be the females rather than the males. A new long-term study on African coucals shows: when males provide all parental care, females can have more offspring by competing for and mating with multiple partners.
