"Young birds have neither crest nor lengthened plumes on scapulars or breast; upper parts brownish gray, with broad rufous edges to the feathers; crown partly gray; neck rufous, fore neck with black streaks; lower surface a mixture of buff and gray." (Blanford.) This species is the commonest of the large herons and may easily be identified by means of the preceding excellent descriptions. In a fine-plumaged male from Anao, Tarlac Province, Luzon, the upper mandible was dusky; lower mandible yellow, greenish toward base; upper part of legs light yellowish green, lower parts brown.
