Storm Petrel 2674680 has been exploring the Welsh coast! Ringed by Teifi Ringing Group at #Mwnt in 2017, it was at Porth Iago in 2018 then this year was caught by Pembs RG at Wooltack Point on 11th July, then just 9 days later was retrapped on Bardsey Island

...it's good if you have a breeding colony

where you can put on GPS tags AND get them off again.
Work undertaken in Spain (Benidorm) with Mediterranean Storm-Petrels has tracked 22 complete foraging trips of individuals from the colony (and back again). Foraging trips lasted 1-4.5 days taking in an impressive 303-1726km - much further than previously thought.

Birds were foraging over deep sea areas of the Alboran Sea and the Cartagena Canyons. If we took these figures and looked at sea depth I wonder how far, and for how long, European Storm Petrels from Nan Ron would forage.
