Not actually a bird but interesting none-the-less. See below from Steve Smith:
Not sure if this the right place but I'm sure that you can pass on the information to the relevant people but I
have seen two European Hornets in Stepaside today. About 5pm and at
18.45pm. They were definitely European and not Asian Hornets. Brownish/
yellow about 1" 1/4 maybe 1"1/2 long. So chuffed as they are only the
2nd and 3rd time that I have ever seen them.
