The unobtrusive little Black Guillemot (Cepphus grylle) is one of my favourite marine birds from the Bay of Fundy area. I first encountered them up close in 1960 when I was doing research on Outer Wood Island off Grand Manan Island, NB, where a good-sized population was nesting in the rocks along the shore.
Guillemots are only about a foot long with a wingspan that approaches 2 feet. They overwinter in the Bay of Fundy when they take on a grey/white plumage. They feed on fish, crustaceans and other marine invertebrates as well as some plant materials.
