The Crossbills were found at Sullom and at Kergord, with the three birds at Sullom proving to be the usual '4E' vocal type that seems to be the norm up here lately... but the Kergord birds were the scarcer '1B's that I've only found 3 times before in Shetland!
The pic and sound clip are of the '4E' birds...
The sound clip also contains Siskin and Curlew calls;
Now we do get quite a few different species and sub-species of Redpoll up here! but this rather scruffy looking individual seems to be in heavy moult, and even has only two fully grown tail feathers. Does anyone care to comment on race?
