Also the Glaucous Gull today at Spurn Jim. Easington beach. It's been around for a while. The Firecrest in bushes just past the gate near the warren showed really well at times. As Andy R said, Chiffs and Wheatear around, Mipits displaying, it's picking up.
Nice day there today as well, warm and sunny.
As for Alpine Swift, I did a migration watch for a while with exactly that species in mind to no avail. With the influx in Norfolk and the south coast involving at least 12 birds there should be a Yorkshire one pretty soon, especailly with this southerly airflow, with Spurn perhaps favourite to accomodate one!
