This Brandt's Cormorant was in the Oceanside marina recently. It was acting a bit dumpy.
Brandt's Cormorant. Oceanside, California. November 8, 2015. Greg Gillson.
As is the case for many fish-eating birds near such busy fishing harbors, it grabbed a baited hook and now wears it as "jewelry." As you may imagine, such a hook may become infected or otherwise fatally injure a bird.
