R & E (1992): Nesting commences in May. At time of R & E there were two known breeding sites in the southeastern corner. The Caruthersville and Miner sites (southeast Missouri) were estimated to have ca. 100 and 150 nests, respectively, in late May 1985. (Jim Wilson, BB 52[3]:11). Only 50-60 nests were located at each of these locations in 1989. (BB 56[4]:146).

R & E (1992): Breeding status outside of the Mississippi Lowlands is less clear, but has been recorded nesting, at least very sparingly, statewide.

Summer 1937 - Nesting outside of southeastern MO
(500+ nests); Marais Temps Clair CA, St. Charles Co.; Wayne Short; R & E, BB 4[7]:84.

June 29, 2008 - Nesting outside of southeastern MO
(2 or more nests); Squaw Creek NWR, Holt Co.; Tommie Rogers, Brian Lomas, Frank Durbian; 22nd Annual MBRC Report, 2008-95. A bird heard at the location of nesting Cattle Egrets (2008-94). The observer asked refuge personnel, Frank Durbian and Brian Lomas to check for nesting. They did, in July, and found two or more nests near the Cattle Egret nests.

R & E (1992): Apparently it was much more common and more widespread as a breeder prior to the early 1900's; both Widmann (1907) and Harris (1919b) mention that it was formerly more numerous.



R & E (1992): Postbreeding concentrations are composed of significantly fewer birds than that of most other heron species. Relatively large numbers are seen through Sept., with small sized groups observed mid-Sept. through Oct. All of the Nov. records at time of R & E are of single birds and the greater majority are of immatures.
