Little Blue Heron (Egretta caerulea) Science Article 4
On 4 July 1976 William T. Everett, Curtis Stuteville and I discovered an adult Little Blue Heron (Egretta caerulea) near the mouth of the New River at the south end of the Salton Sea, Imperial County. This bird was perching in an area of drowned trees along the shore of the Sea. The Little Blue Heron was similar in size and shape to the several Snowy Egrets (E. tbula) available for comparison nearby, but without any bushiness to the head, so the head appeared smaller and the neck narrower.
