Mountain Plover

Colo Bogs Wildlife Management Area
|
3 miles east of Colo, County Road E-41, 1/2 mile north, section 1 T83N R21W, Story County.
|
General: Recently plowed field with several pothole ponds Specific: The bird stayed in the waterways that led to the ponds. These areas were wet and contained no vegetation.
|
The documentation form by Hank Zalatel is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Dinsmore, Mark Proescholdt, Thomas H. Kent, Jim Fuller, Robert K. Myers, Francis L. Moore, Tom Staudt, and Paul Martsching were submitted later. Other observers include Cal Knight, Bernie Knight, Eugene Armstrong, Eloise Armstrong, Steve Dinsmore, and unidentified other observers. | Elimination of similar species: Golden and Black-bellied plovershave [sic] gray-white and brown-gold scaly backs, this bird's back was brown and was unmarked. These two plovers have streaked throats which this bird did not have. These two plovers have streaked breasts which this bird did not have. The white above the eye of this bird was clear and contained no streaking as does the Black-bellied Plover. The bird associated with Golden Plovers in breeding plumage and one that was not so that comparison could be made on the spot for the two plumages. | The original documentation form event lasted from 18:30:00/18:55:00 July 9, 1986 and 18:45:00 - 19:15:00 on July 10, 1986.

But when we saw a female or immature ruby-throat later in the day, we remarked that it looked smaller, slimmer and greener than the rufous. [...] The distinct, rusty color, especially on the back, fits no other species. | The original documentation form event lasted from 18:30:00/21:00:00.

The larger size, extent of reddish underparts, leg color, white rump, and wing stripe confined to the secondaries eliminates Sanderling. | The original documentation form event lasted from 07:31:00/07:57:00 and 08:17:00/08:26:00.

The documentation form by Robert Cecil forms the basis of this record. Another documentation form by Jim Fuller was submitted. Other observers include Chris Pilliod, Jim Sandrock, Cal Knight, Jane Fuller, Charles Fuller, and James Huntington. | Elimination of similar species: The only species I could not eliminate on the basis of field marks observed was Yellow-footed, which according to Tom Kent (telephone conversation) is not a known vagrant. More objectively, the Yellow-footed is supposed to be larger than a Herring Gull. As stated above, this bird was about the size of a Herring Gull, or perhaps a little smaller. I don't feel it was larger than a Herring Gull. Seabirds (Harrison) warns of possible confusion with dark race Herring Gull. I have not heard of this race occuring [sic] in Iowa. In any event, the foot coloring was incorrect for Herring Gull, which has pink legs in contrast to this bird's yellow legs. | The original documentation form event occurred at various times.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record.
