No more than one or two pairs have been seen at one time; they are difficult to find. Period of Occurrence: There are so few records that little is known of the arrival and departure times, but extreme dates are 16 April and 12 September. Breeding: The first nesting attempt at Cheyenne Bottoms in 1974 failed, but an attempt in 1976 was successful. The species has nested there most years since then, but not all nests have been successful. Look for it in breeding areas with Little Blue Herons and other egrets. The nest is a typical heron nest composed of sticks and is usually placed in low shrubs or cattails; some may be on the ground. The eggs are pale greenish blue and usually number three to four, but there may be as many as Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thompson, Max C; Ely, Charles A.
