The female on the left is a Wurdemann's Heron. A lot of discussion as to how they should be listed & how they came about. They are very rare and mainly found in the Florida Keys. However, they do wonder up to South Florida from time to time. Probably the most practical explanation is a cross between a Blue Heron & a White Heron (Blue Heron/white morph). She is mated to a Blue Heron.
