in Iowa. The species is listed by J. A. Allen (White's Geol. of 

 Iowa, ii, 426). Keyes and Williams report it as "very rare. Has 

 been taken at Des Moines and in Floyd county in August" (Bds. 

 of Iowa, 1889, 120). 



County records: Blackhawk — "an uncertain late summer and 

 fall migrant from the south; young birds wander northward prob- 

 ably as soon as fledged. Sometimes appears in considerable num- 

 bers in Blackhawk county. One spring visitor, probably acci- 

 dental, recorded "(Peck). Lee — "rare; mounted specimens with- 

 out dates often seen. A flock on August 29th is my only date — 

 Keokuk district" (Praeger); "rare summer visitant. I think 

 both the Snowy Heron and L,ittle Blue Heron were present around 

 Keokuk in August, 1891 . I positively identified two young birds, 

 male, shot" (Berry.)

The Little Blue Heron is also a casual visitor or straggler in 

 Iowa. This species is remarkable for exhibiting dichromatism, 

 adult being slaty- or grayish-blue, and immature birds pure white, 

 or nearly so, sometimes mixed with bluish. 



The species was listed by J. A. Allen (White's Geol. of Iowa, 

 ii, 426), and Keyes and Williams (Bds. of Iowa, 1889, 120) report 

 it as "rare; observed during the summer in the eastern part of 

 the state." It was "observed by Trostler near Omaha June 15, 

 1897, and August 15, 1903. Bruner records a specimen from near 

 Omaha years ago, brought to F. J. Breeze to be mounted, but 

 whether killed in Iowa or Nebraska is not known. It has been 

 reported as breeding north of Omaha on the Iowa side of the 

 river, but this is probably an error. Possibly some of the records 

 of the preceding species may have referred to the young of this 

 species, since at that age it is white" (Rev. Bds. Neb., 33). 



County records: Jackson — "common summer resident" (Gid- 

 dings). Lee — "I think both Snowy Herons and Little Blue Her- 

 ons were present around Keokuk in August, 1901. Although I 

 did not shoot any Little Blue Herons, still I saw several birds 

 that were in a mixed plumage and I could not place them any- 

 where else" (Berry). Linn — "last fall (1903) a white Heron was 

 shot about five miles from Cedar Rapids, and from what I could
