    Details: While going through the lists for the day, Fritz spotted this bird standing on the dock below the landing at which we had just arrived and mere meters from where we departed the boat a few minutes earlier. I then walked down onto the dock and took several photos before this bird flew to one of the braces for the building above, where it remained for us to take some more photos. I never heard this bird vocalize and it was rather sedate while under observation apart from it sone short flight. Not only was this bird a year older than the other three Yellow-crowned Night-Herons that were at the state park, but after seeing this bird we drove over to the state park marina and saw all three first-winter birds that have been there.
    This was a stocky, medium-sized heron with a rather massive bill, a blocky head, a medium-length neck that was more massive than those of most herons yet slimmer than that of a Black-crowned Night-Heron, short and seemingly rounded wings, a short tail, and medium-length legs that had more mass than those of an egret. I thought the bill was quite deep and that it was about as long as the head was wide, with a culmen that curved subtly yet smoothly downward to the pointed tip of the bill. The forehead was steep but short and the crown was gently rounded back to the more strongly rounded junction of the crown with the nape. When extended, this bird’s neck was both long and slim for a night-heron even though it was both shorter and stouter than that of a egret. The body was plump, full-chested, and with a posture that was more upright than diagonal when the bird was alert. I noted minimal primary projection on short, rounded wings that appeared to fall right at the tip of the short tail, which was obscured by the closed wings.
    This bird’s plumage patterns were clearly those of a subadult bird in that they combined a faint suggestion of the pattern of an adult on the head with the generally grayish or brownish body and wings of a young bird. The head was generally a slate-gray in color, but with the forehead and crown brownish centrally yet with a paler and somewhat yellowish frame that extended through the supraloral region and along either side of the crown. I also noted at least some suggestion of a pale gray stripe extending narrowly below the eye before expanding on the auriculars in a faint suggestion of the adult cheek-stripe. The chin and maybe also the upper throat were pale yellow and thus contrasting conspicuously with the more blackish face. I did not see the neck all that well, but it did not appear to contrast obviously with the body. The back and scapulars was a medium to dark gray and each of the larger scapular feathers at least had a relatively broad band of slate gray running down the center that was bordered on either side by lighter gray to create a striped appearance to the generally dark and grayish upperparts. The wings contrasted as lighter and slightly browner than the back, and at least most of the covert feathers had a small, pale spot where the shaft met the tip. The larger greater coverts, and maybe also some of the lesser coverts also had a paler stripe along the leading edge that gave the lower part of the closed wing a striped appearance that was even more conspicuously given the narrow but well-defined fringes on the tertials. I did not see the underparts as well as I did the upperparts and wings, but what I did see appeared to be quite dusky and seemingly not as conspicuously striped as were the first-winter birds seen shortly later.
    The bill was a dull, blackish in color, and the irides were orangey and contrasting sharply with the black pupils. The legs appeared to be blackish when seen from the front, but greenish or yellowish-green when seen from behind; however, I cannot now remember the color of the toes.
