Updates from the @ifv-whv.bsky.social's long-term individual-based study on common terns breeding at the Banter See in Wilhelmshaven; provided by me - Sandra. With a side of gull-billed terns from @gullbilledterns-de.bsky.social's conservation project.
I was also lucky enough to be given the chance to talk about the Banter See common terns. Although they are protected against two major threats that many birds breeding in the Wadden Sea region face – predation and flooding – other cumulative pressures still affect them too.

Out @animalecology.bsky.social today - a paper with David Ewing in which we explore the #HPAI outbreak in the terns. We find bird-to-bird transmission to be the main driver of infection and estimate the probability of mortality to drop from 0.26 to 0.14 from 2022 to 2023: doi.org/10.1111/1365...

When we hypothesised female terns to have lower mercury levels than males due to egg laying, @matteobeccardi.bsky.social et al designed an elegant experiment to prove the effectiveness of this pathway. That proof just got published & the open access paper can be found here: doi.org/10.1016/j.en...

And to add some more beauty to the internet: here's a close-up of Dr Schnelle, with her gorgeous hat crafted skillfully by various members of the @ifv-whv.bsky.social, fired on by @robertrollins1892.bsky.social. 🥰

Look at that! @genmig.bsky.social, @gullbilledterns-de.bsky.social and I fledged this supercool chick at the @ifv-whv.bsky.social on Wednesday. Let us proudly present to you: Dr Anna Schnelle.

Out now in Environmental Research – Anna’s new paper in which she assesses the levels of 118 contaminants in unhatched eggs and dead chicks found in the last and endangered population of gull-billed terns in Central Europe, breeding at Neufelderkoog: doi.org/10.1016/j.en...

Ooooh, one of our beautiful terns made it to the cover of the issue of Ethology that contains Melina's study on individual behavioral responses to novel stimuli: onlinelibrary.wiley.com/doi/10.1111/...

And here it is - Justine's last thesis chapter got accepted too and can now be read as an open access paper in Environmental Research: doi.org/10.1016/j.en...

Our neighbours at the Banter See are no fan of the terns. Luckily the terns don't give a shit. Oh, or maybe sometimes they do. :-)

Hatching is hard work. ❤️

Arrival was earlier, but it does not look like we are going to end up with many more birds this year than last. I guess the 'silent reservoir' was used up, such that we now wait for new recruits from last year's cohort to start making up for the severe losses HPAI induced in 2022 and 2023.

Three weeks ago, the little one on the picture on the left was found cold and almost dead. But yesterday, it was the first chick from 'island A' to get its transponder. Happy fledging, little survivor. May you recruit to produce many little survivors yourself. ❤️

The facial expression of a parent with teenagers. I can relate. 😂

Weekend loveliness: retrapping a gull-billed tern carrying a GPS and getting to know a few of the newest colony members.

The tracking of the gull-billed terns of @gullbilledterns-de.bsky.social is going really well and we're seeing lots of interesting variation in space use. Here's two examples of tracks collected across the last 8 days:

Here’s a video of a fun pilot study on tern personality aspects, in which Melina tested how the birds respond to a novel object placed at their nest. Linea from nest 431 did not care much about an orange cone making an appearance. :-)

Fresh siblings and lots of chick ringing during today’s check of the colony. Even the rain held off to let us do our job. 🐣

The Banter See season in numbers so far: we have registered 372 birds, 189 nests have been initiated, 42 blood samples have been collected and 28 birds have been caught to attach or remove a geolocator. Next up: chick ringing. Hatching should start any day now. ❤️

From one field site to the next. Back at the Banter See, Kator & Anea from nest 11 on island C have turned into the managers of the entire island, bloodsampling any scientist that dares to come close. :-)

Last weekend was exciting! Together with @gullbilledterns-de.bsky.social, and thanks to the amazing teams at Druid & Interrex, we deployed the first gull-billed tern with a GPS. It returned to the nest after a quick preening session and for the last 3 days has shared its foraging sites with us.
