For anyone local: the @ifv-whv.bsky.social will have a stand at the Long Night of Science celebrated at the Botanical Garden tonight, and we’ll give two talks too. Come find us, we’ll be happy to see you!

Current status of @gullbilledterns-de.bsky.social's birds we deployed with a GPS logger : 7 birds are out of range, and 25 scattered across Germany, the Netherlands, France, Spain and Portugal.

Question: do I know anyone near Nantes who would be willing to pick up a dead gull-billed tern and its logger? L49 has sadly been killed near a road. I’d be very grateful for a picture and the logger and would of course reimburse postage.

Meanwhile in Noord-Holland. One of our gull-billed tern chicks doing some playful flight training in between feedings and naps. With slootjes (ditches) full of frogs and a parent nearby bringing them on life can be easy. Thanks to Fred Visscher for the lovely footage.

Last year I posted the photo on the left, showing how our Banter See terns are perhaps not so scared of the neighbour's scarecrow. This year I can add the photo on the right, showing how the scarecrows have lots of company. Bird shit all around showing how well everyone is fed. It's a good season. ❤️

Lachstern jong T86 had geluk. Hij slikte de kikker die hij van z’n ouder kreeg op tijd in. De kokmeeuw was te laat. Gull-billed tern chick T86 is lucky. He swallowed the frog he got from his parent quickly enough. The gull was too late.

A Review in Nature Reviews Biodiversity discusses population trends of migratory birds, dominant threats in different regions and existing conservation initiatives. It also recommends integrative conservation approaches for the future. go.nature.com/4z0KWae 🌎🧪

We branched out a little and contributed mercury measurements to this study on Arctic barnacle geese by Matteo Schiavinato et al, published in Environmental Pollution: doi.org/10.1016/j.en...

The Banter See season is slowly drawing to a close. The first day of August ended with 717 birds being registered. Last year this time that number was 477.

Listen up to what L04 has to say! Lachstern - Gull-billed tern

It looks like the first logger bird of the project we share with @gullbilledterns-de.bsky.social has left the continent. L38, after short stopovers in the Netherlands and France, was last recorded in Andalusia on the 25th of July. No more data points until next spring, I suppose.

A very strong El Niño is under way, strengthening through 2026 and into 2027. This presents a unique opportunity to observe and document how seabirds are responding to a warming ocean. Researchers, monitoring programmes and citizen scientists worldwide are warmly invited. Register: bit.ly/45hEsWz

Although the GPS loggers are teaching us lots of really cool things about the members of Central Europe's last gull-billed tern colony, sometimes the news is just the saddest:

The good news just keeps coming and coming today. Look at these sensational data provided by the tracking project we have with @gullbilledterns-de.bsky.social!

Two photos that make us very happy this morning – story below. :-)

See that cute gull-billed tern chick thinking of leaving the safety of the frog- and electric fence that allowed it to grow up behind? Well, it did, and with a logger, so that you can also see its first trip away from the colony on the right. ❤️

📖 Published📖 Between-species contagion drives HPAI transmission and mass mortality in seabirds 🦠 'This study demonstrates that carcass data can provide epidemiological insights but also act as an early warning system for continent-wide patterns of spread'🕊️ 👇️ buff.ly/Zo6d8WH

Highly pathogenic avian influenza H5 detected in a greater crested tern at Robe, Limestone Coast, South Australia. All previous detections in Australia were in migratory birds that had likely brought the disease from the subantarctic, but the greater crested tern is a resident seabird in Australia.

Deadly H5 bird flu found in local Australian seabird for first time

Out now & open access in Avian Pathology - a collaborative paper showing how highly pathogenic avian influenza (clade 2.3.4.4b euBB) was introduced, and led to high mortality, in breeding colonies of black-headed gulls and common terns in Germany in 2023: doi.org/10.1080/0307...

Some happiness for your feeds: Kamala with the two fledglings she reared with Bismarck this season. ❤️

This graph is getting funkier and funkier every day: 39% of the ringed population is now made up by 2-yr-olds! And the current cohort is also still doing really well.

Until Friday, Australia was the only continent free from HPAI H5N1. Sadly, this is not the case - a 2344b confirmation in a Brown Skua, and a suspected case in a Northern Giant Petrel which turned up in WA. 👉 www.abc.net.au/news/2026-06... (1/x)

After last year’s successful pilot study, GPS-tracking @gullbilledterns-de.bsky.social's birds, we’re back at it this year. The lovely bird @harrykuipers.bsky.social photographed is L39, a 5-yr old female, breeding with 4-yr old R75 on nest 8. She laid two eggs that both hatched successfully.
