This photo (taken at 12:53 PM) was obtained shortly after my arrival on site, and it provided a nice feeling for this tall bird wading through the tall grass--and it did so without obscuring important, potentially viewable, details of the bird. It is not, though, a side-on shot, so it does not provide the high-quality view of the face of the bird that may be had in a couple of the other photos herewith, especially in the sole digiscoped photo.

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.
