I was thinking some kind of goose when I saw this, but not so sure now.
ID help - I think it was a warbling vireo... very small light grey with a lighter eyebrow stripe
Rummaging through the undergrowth, picking at a dead fern. Orange bands on both legs. Held a nut under one foot and pecked it really hard repeatedly. Very curious about me but put a little distance between us
Saw one sitting at the top of a bare tree, and saw another go into a hole in the dead tree pictured.
Not sure if it is a mallard. Can anyone else comment?
