Every world region has warmed since the mid-20th Century. The Arctic and Europe seems to be warming more than other regions though.

Pioneering #Oystercatcher!
Up until about 1840, British Oystercatchers were coastal breeders. Inland nests first appeared in Grampian (Scotland), a trend that spread to England by about 1900.
Now, many pairs breed on roof tops.

First sign of autumn?
The BirdTrack graph for Black-tailed Godwit is about to kick upwards, as the first failed breeders return from Iceland, to join flocks of immatures on British & Irish estuaries.

There are huge pressures on UK-breeding Redshank, especially on the coast.

Good luck, also, to everyone protecting beach-nesting Ringed Plovers, Oystercatchers and terns.
With a bank-holiday heatwave, you're going to have lots of people to talk to!

How strong is site fidelity in Black-tailed Godwits?
We know that adults return to the same sites each year but what do their chicks do, when it is their turn to breed?

Wader conservation is not for the faint-hearted. Curlew fieldworkers are required to be many things at once: skilled practitioners, negotiators, communicators, storytellers, problem-solvers and often unofficial psychologists. 🧵

It's important that France renews the ban on hunting Curlew, each year.

Birds tagged when wintering in Brittany return to English and Scottish breeding sites.
Species is 'near-threatened' globally.

When a wader joins a flock of migrating birds, it may be heading in the wrong direction?
Seem odd?

Interesting track of homeward-bound Icelandic Golden Plover (Tómas Gunnarsson posted on Facebook).
Portugal to E England, Netherlands, Orkney & Iceland.
Caught up in flock heading to Europe?
Readjusted to head to Iceland?

Thousands of Black-tailed Godwits will fly back to #Iceland in the next two months. If they encounter strong northerly winds, flocks can turn up anywhere in Scotland.

Perfect weather for the spring Equinox today, a critical trigger for bird breeding, as increasing daylight boosts hormones, initiating migration, territorial singing & nest building. But some started early & today the first cute mallard ducklings were spotted, a huge brood of 18

Portugues rice-fields two weeks ago.
A melting pot of 'limosa' and 'islandica' Black-tailed Godwits.
Most 'limosa' will be heading to the Netherlands:

Some 'islandica' will take the same route to Iceland:

Hoe de sloten in Nederland verdwijnen. De Volkskrant bracht in kaart hoeveel sloten in Nederland verdwijnen. Daarvoor zijn kaarten met watergangen verzameld en vergeleken, duizenden luchtfoto’s bestudeerd en honderden bestemmingsplannen doorgeploegd. Uit het onderzoek blijkt dat er tussen 2017 en 2024 ruim dertigduizend sloten op boerenland zijn verdwenen. 33% van deze sloten – ongeveer tienduizend – ligt in een gebied waar dempen zonder vergunning niet mag. Sloten zijn er niet voor niets. In natte tijden voorkomen ze natte voeten en bij droogte houden ze water vast. linkedin.com/posts/robert-ti…
