In this photo (taken at 1:06 PM) one has a good view of its top side. I would call attention to some evidence that this is not a fully adult bird: Upon close inspection of this photo one can see (lower half of bird) some residual, very broad white tips (with broad dark markings) on the upperwing coverts, which are characteristic of the wing coverts on immature individuals. Adults have much finer dark/light barring in this area.
Detalles de la observación
Based upon study of my photographs and review of my field notes, this individual exhibited somewhat less than full adult plumage, although it had mainly adult features. Nonetheless, I believe that labeling it (below) as adult might be misleading as to its actual plumage state (indicating age), so I am listing it below as "immature." PLEASE NOTE: In discussing below my photos I will point out specific features indicating that this individual evinced less than full adulthood, fully recognizing, though, that most of its features were like those of adults. I will, using this set of photos, also document this bird's capture and ingestion of a Hispid Cotton Rat and will supplement that by providing some visual observations of this heron obtaining and consuming its New Year's Day feast. This Bare-throated Tiger-Heron initially was found (and reported) on December 21, 2009 by R. Nirschl and R. Snyder. Publicity concerning this first-ever (USA) finding brought many birders to this state park to search for it. The present report concerns my own fifth effort to find and photograph it. A few days before this I had had a very brief sighting of a bird in flight, near day's end, that closer birders had affirmed was this desired species, but from my greater distance, seeing the bird briefly in flight in low-level light was inadequate for definitive personal identification and for photography.
