Best Crest

27 November 2020:

Hooded mergansers (Lophodytes cucullatus) are twice named for their crests which they raise and lower at will. “Hooded” refers to the crest, of course. So does the Greek Lophodytes: lophos = crest + dutes = diver.

Females do the crest thing, too.

And in slow motion …

… it’s the best crest.
