The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: The more common Forster's Tern has wings all one color or paler on the primaries. One was present at the slough this day. However, young Forsters, I've been told, can have dark primaries. If this is so + they return those feathers in the spring, the possibility of Forster's Tern is not entirely eliminated.

The Commons differed from Forster's terns by having dark primaries (adult) and on eye patch that circled the back of the head (other bird).

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.

Size limits the question to: Kestrel or Merlin? The tail banding + uniformly gray upper parts (the latter seen only briefly) make it a Merlin. I've never seen anything behave like that. | The original documentation form event lasted from 09:30:00/09:35:00.

Or hybrids. Unfortunately, the identification depends on things I do not know. Ruth Green informs me that some Rose-breasted Grosbeaks in early September are so orange on the breast one would think them Black-headeds. Are these young Rose-breasted? What about the call? Do Rose-breasted Grosbeaks make a lower-pitched call, more mellow than the distinctive high-pitched call that is the only one I know for them? If you know, please tell me. These were odd-looking grosbeaks but I can't really identify them. | The original documentation form events occurred around 08:45:00 and in the afternoon.
