We mapped out the migrations of over 10K ind ⚫-tailed godwits (!) to characterize connectivity between sites in Europe and Africa.
We compiled tracking data, ring recoveries and resightings: >400K records in total! (1/5)

Latest WaderTales blog focuses on the newly red-listed Broad-billed Sandpiper.
It lists all 16 waders/shorebirds that had their conservation status revised in the wrong direction:

How volcanic eruptions help waders Areas of Iceland that have experienced high volcanic ash deposition can accommodate up to three times as many breeding waders. When Tómas Gunarsson began his PhD at the University of East Anglia on…

We were recently asked how volcanic eruptions affect Iceland's birds.
Long-term gain. Short-term pain.
