Red grouse showing well at Hobbister and Burgar Hill RSPB reserves in the early month, with great views of a male peregrine on 10/5.
The best bird however arrived on our “hide list” on 10/5, when 8 fully adult beautiful white snow geese flew low up the fields and over the house…quite extraordinary!
Cetaceans and sharks all arrived during mid month, with a solitary Risso’s dolphin off Grimness Head (11/5); 5 Minke whales showing really well at Noup Head on Westray (14/5); and a basking shark in Echnaloch Bay on 16/5.
Fantastic drake garganeys at Graemeshall Loch on 12/5 & 29/5, and whimbrels overhead regularly throughout the county.

Migrants such as blackcap, whitethroat and spotted flycatcher heading through on 24/5, but the best bird of the month was a singing male rustic bunting in the village of St. Margaret’s Hope on 24/5.
