Congrats Alfredo! So well deserved. Great to hear that you made it back to the Iberian peninsula.

Schade eigentlich. Was sagt denn die jetzige Empfehlung für Kinder (Teenager mit wenig Tageslicht) oder Ältere (>60 J) aus?

Our new study shows that, for the three vastly different examples and 38 other species, the way how survival & reproduction respond to threats is also vastly different! But, overall, populations fluctuate strongly when several climatic variables change in tandem: doi.org/10.1093/pnas...

I really enjoyed this one, a beautifully written natural history account about lekking in birds. And the Darwin-Wallace argument over sexual selection never gets old.

5/5 In addition, a huge effort is made to protect the #critically #endangered southern #dunlin. With expertise of Vroni Rohr-Bender and others, 26 chicks got an advantage be growing up in our aviary, before they got released back in the meadows, hopefully successfully #boosting the #population.

4/5 Most time of the field season was spent searching for nests and to ringing the #chick and #adult ruffs. We found 65 nests in total which is an excellent result. Adult birds also got a radio or #GPStag to investigate #habitat use and behaviour. Aren't the chicks cute?

3/5 Independent males have striking colours and are #aggressive. #Satellite males are mostly white coloured and have more #sneaky behavior. Female-looking faeders are extremely rare.

Here an independent male is pecking a satellite to show its dominance.

2/5: Fieldseason started in early May when the #ruffs arrived in the coastal meadows of the #BothnianBay. Male ruffs are known for their fascinating #lekking #behavior! A true spectacle! The existence of the different male morphs is unique.
