A typewritten journal compiled by Walter Rosene detailing his bird study at Ledges State Park as well as additional field work. The journal covers the years 1918-1941 and contains details from several of Rosene's bird watching interests, including the following: observations and photographs from Ledges State Park, multiple poems, bird observations in Boone County (1918-1929) and within 30 miles of Ogden, IA (1930-1939), a life list of birds, nesting records of Barred Owls and Great Horned Owls, Christmas bird census counts (1922-1936), a survey of Martin colonies in Ogden, a list of Rosene's publications, and timeline of his participation in the McGregor Wild Life School.

The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Jim Fuller, and Brian Blevins were submitted later. Other observers include Ross Silcock, Peter Petersen, Kelly McKay, Corey Blevins, Jim Scheib, Jim Sinclair, John Daniel, Tim Schantz, Cal Knight, Bernie Knight, Chuck Fuller, David Youngblut, Beth Brown, Sherry Dragula, Bill Overland, Jane Overland, John Miller, Eugene Armstrong, Eloise Armstrong, and unidentified other observers. | Elimination of similar species: The date of observation is historically good for a vagrant western flycatcher species, so this was in the back of my mind in assessing the characteristics observed. The presence of both eye ring and wing bars, in addition to size and shape, indicate that the bird fits the Empidonax complex. The combination of green back, yellow throat and pure orange lower mandible with no markings would eliminate Least, Hammond's, Dusky, Gray, Buff-breasted, Alder, and Willow Flycatchers. A juvenile Acadian can be eliminated by the short primary extension, color of the wings, size and shape of the eye ring, and active behavior. Only three species are indicated by the green upper parts and yellow under parts. Two are separable only by voice. The choices were between Yellow-bellied Flycatcher and Western (Cordilleran and Pacific-slope) Flycatcher. Back color is greener in Yellow-bellied and more olive in Western. Although the back looked olive, this was rather subjective. According to the Audubon Master Guide, behavior would be more indicative of a Yellow-bellied in that the bird was not flicking both tail and wings. According to Kaufman, however, behavior is quite variable. Three characteristics made me lean more toward Western complex. They were peaked appearance to the head (usually smooth and rounded in Yellow-bellied); almond-shaped eye ring (round, narrow, and more even in Yellow-bellied); and browner wings than eastern Empidonax. The color of the wings is again subjective, but the contrast between wing color and wing bars was less than the black/white (or even black/buff in fall birds) of eastern birds. Even with the variability that may occur in any Empidonax, it is unlikely that these three characteristics, which are common to the Western Flycatcher, would appear simultaneously in a Yellow-bellied Flycatcher. Further support is found in the Audubon Master Guide to Birding where it states in the description of Western Flycatcher, "...olive wash on the breast, flanks, and especially the sides tends to highlight a midventral yellow stripe" - one of the more obvious characteristics when viewed at close range from the front. IF the call notes heard belonged to this bird, it would indicate a Cordilleran Flycatacher, the most likely vagrant. None of us were able, however, to get the bird to call as we were observing it. Cal Knight played a tape and the bird became very agitated but did not call. | The original documentation form event lasted from 11:00:00/14:00:00 on November 14, 1992 and 11:30:00/13:45:00 on November 15, 1992.

The documentation form by Ann Johnson is the earliest and thels, one an adult male and the other a probable adult female, were present on the same day. Oftentimes all three birds were on the feeder concurrently which allowed for a number of comparisons. Characteristics which differentiated this bird from the Common Redpolls and identified it as a Hoary Redpoll: underlying color was lighter than the warmer, darker brown of the Commons, More extensive white feather edgings to the secondaries, tertials, and scapulars than shown on Commons, Broad white edge to the greater coverts, Buffy face and strong white supercilliary, Smaller red cap, Broken and shorter flank streaking, Short, triangular bill with resulting pushed in face, Nearly white undertail covers (Although brightly colored adult male Common Redpolls may have diminished markings on their undertail coverts, this bird had no red except for the cap.) | The original documentation form event lasted from 07:30:00 and periodically throughout the day. one that forms the basis of this record.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: The body and bill structure eliminated all but hooded gulls and the brown plumage indicated a first year bird. Size close to Ring-billed, in addition to plumage already described, eliminated some of the smaller hooded gulls. The most likely candidate for confusion would be the Franklin's Gull. Juvenile Franklin's shows a hooded pattern early in development rather than a brown wash on the head. Franklin's tail band would also be incomplete with white feathers showing on the outer edge. It would also show fewer dark primaries, with the inner flight feathers more approximating the mantle and inner wing color. No other small gull has this characteristic. | The original documentation form event lasted from 11:45:00/12:10:00 and 15:30:00/14:00:00 [sic].

And Gull in question is same size as Herring Gulls; Greater black-backed would be much larger. (B) Lesser black backed - Gull in question has pink legs and feet, and has much more white on primaries. (C) Western - Gull in question has considerable white on primaries, and does not show dusky trailing edge to underwing. Also has broader white trailing edge to upperwing than would the Western. (D) Herring Gull - dark race - no experience with this, but those shown in Harrison do not show as dark a saddle as Gull in question, nor as much white on primaries. | The original documentation form event lasted from 15:00:00/15:30:00 on February 12, 1989, 12:15:00/12:45:00 and 16:00:00/17:30:00 on February 14, 1989.
