Reddish Egret (Egretta Rufescens) in AZ is a vagrant from the coastal areas of the Sea of Cortez. There have been about 30 records; this is the third one I've seen since 1994. It was discovered in Chandler, AZ, on Saturday, December 27, 2008. I was able to relocate the bird on Dec 28.

There are two color morphs of Reddish Egret. All western birds are dark, while about 2-7% of eastern birds (Gulf coast to Florida) are white.

And now I’ve seen four in AZ with this bird near the Gilbert/Mesa line September 3, 2012.
