The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. | Elimination of similar species: The only bird that this duck reminded me of was a Ruddy Duck female, but this bird was difinitely [sic] not this species, and is mentioned because of vague plumage characteristic similarities. | The original documentation form event lasted from 13:20:00/14:45:00.

Records Committee review for a Black-crowned Night-Heron at Cedar Lake in Linn County, IA on January 2, 1998. Includes one record review document with votes and a documentation form.
|
Kent, Thomas H. (Thomas Hugh), 1934-
|
Black-crowned Night Heron
|
Cedar Lake
|
Cedar Lake, Cedar Rapis, Linn Co., IA
|
Large round backwater lake kept open by output from Quaker Oats Plant. The lake was half frozen two days ago, but two warm days made it ice free.
|
The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. | Elimination of similar species: The short legs and large rounded head with thick neck are the main features that distinguish immature Black-crowned from Yellow-crowned Night-Herons. The round white dots on the upper wing are supposed to be more prominent on the Black-crowned, but this is difficult for me to judge. | The original documentation form event lasted from 13:05:00/13:30:00.
