| Occurrence Remarks |
The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: This heron resembles every other White Heron or egret. Albino Heron: this is what I thought it was at first, but it turned out to have color in bill & legs. "Great White Heron" can be eliminated by size and range. Snowy Egret: has black legs and bill. Great Egret: has yellow bill w/out black tip, & dark legs. Cattle Egret: has yellow to orange bill without black tip, has yellow to dark (not green legs) & is sociable, & wouldn't spend over a week in a marsh. Reddish egret: has a similar bill, but with base flesh-colored rather than gray. Has bluish, not green, legs, has a shaggy neck, and is unlikely to be found in Iowa. The white primaries eliminate other white large birds. The only thing left is immature Little Blue Heron. |

| Event Remarks |
Viewing Conditions: Usually seen from half way or farther across the slough, but on August second I waded through the muck on the east side of the slough and got within 30 yards (even less?) of the bird. All the wood Ducks near to flushed, but I got a clear view of legs & bill w/ 8.5x Binoculars. Alternate sun & shade from clouds. Little wind. The bird was north of me at noon. |
