Miscellaneous Notes:
- On 01 August 2018, Jean-Guy Beaulieu found and photographed a banded 1st summer Black-legged Kittiwake in Les Escoumins, Quebec. After doing a little investigating, I received a reply from a French biologist who claimed the bird - apparently the first banded French kittiwake to be found on mainland America. More here.
