Interesting track of a homeward-bound Icelandic Golden Plover (@tomasgunnarsson.bsky.social on Facebook).
Portugal to east England, then Netherlands & Orkney.
Caught up in flock heading to Europe and readjusted to head to Iceland?

Dunlin now VULNERABLE on Iceland's RED LIST.
One of the waders most impacted by new forestry plantations:
wadertales.wordpress.com/2022/06/18/i...
Over 50% of Europe's Dunlin nest in Iceland so recent declines are of concern to whole East Atlantic Flyway.

Putting this in context:
About 75% of Europe's Whimbrel breed in Iceland.
Over 50% of Europe's Dunlin.
About 50% of Europe's Golden Plover.
About 20% of Europe's Redshank.
SCARY!

At the end of every new road/track in Iceland is a new summer cottage, a tourist development, a newly planted forest or energy infrastructure.
All these developments impact breeding waders but the birds' problems start with the road.

We saw a colour-ringed Oystercatcher on West Sands, St Andrews, yesterday. @jengill.bsky.social
She nests on the 9th green at Selfoss Golf Club (Iceland).
St Andrews seems an appropriate winter home!

1.5 million pairs of wader return to #Iceland each spring.
Where do they nest and how vulnerable are they to habitat changes, many of which are linked to 'development' proposals?

Why track waders?
This blog has two aims – to share important scientific and conservation stories revealed through shorebird tracking work and to encourage scientists to make their data available via the Global Wader platform.
