Hi MassBirders,

I don’t think it has been mentioned here yet that there were apparently *two* separate Mew Gulls photographed on Race Point on Sunday, and they belonged to two different subspecies! According to comments by Amar Ayyash on FaceBook in the MA RBA group, Alan Kneidel and Nathaniel Marchessault's bird was the European subspecies “Common Gull”:

but Will Sweet’s bird was instead the Siberian subspecies “Kamchatka Gull”:

Good birding,
