The reddish egret (''Egretta rufescens'') is a medium-sized heron. It is a resident breeder in Central America, The Bahamas, the Caribbean, the Gulf Coast of the United States, and Mexico.〔 There is post-breeding dispersal to well north of the nesting range. In the past, this bird was a victim of the plume trade. According to the Texas Parks and Wildlife Department, there are only 1,500 to 2,000 nesting pairs of reddish egrets in the United States — and most of these are in Texas.〔 They are classified as "threatened" in Texas and receive special protection. ==Description==
