    I’m calling that the same “baleful eye” guy we had recently, albeit an immature one. That’s without consulting my trusty Sibley, which my better half has taken to using for her docent stints at the seal sanctuary, then leaving in random locations upon her return.

    Oooh, nice shot! I know what it is, so I won’t spoil it for the newbies (not that I’d consider myself “advanced”).

    Ooo OOOOO I know this one. Those birds have the greatest necks!

    It looks like a juvenile yellow-crowned night heron…that’s my best guess.

    Two key field marks to distinguish from similar birds: size and extent of white spotting on wings, and shape and color of bill…

    Well, since no one has stepped up since yesterday, I’ll say that it looks like a juvenile Black-crowned Night-Heron. The field marks noted by Set above are indeed pretty definitive.
