Hahn, Tim Dwyer, Calvin Knight, Bernadine Knight, Garnita Seward, Ramona Sommerlet, Phyllis Harris, John Robinson, John Hoogerkeide, Maggie Hoogerkeide, Nancy Slife, and Mark Proescholdt. | Elimination of similar species: Similar species, Common Redpoll. The first Common Redpoll appeared at our feeders January 13, 1982. The flock of common Redpolls has grown to approximately 40-50 as of February 9, 1982. Within this flock of Common Redpolls there are many females which appear quite light in coloration. I have been able to observe many times a side-by-side comparison with the Hoary Redpoll and light, female Common Redpolls. The Hoary Redpoll appears much lighter and silvery in coloration. This contrast is quite obvious. The Common Redpolls back and nape have an overall brownish cast with buff and black stripes on the back compared to the soft gray cast of the Hoary Redpolls back with silver + black stripes - no buff coloration. Also the very fine, pencil-thin lines along the flank of the Hoary Redpoll differs from that the heavy flank-lines of the Common Redpoll. The Hoary Redpoll's rump and undertail coverts area without any flecks or stripes, but the Common Redpolls rump and undertail coverts have flecks and streaks. | The original documentation form event began around 11:45:00.

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 Mary Jo Hartogh is the only one submitted and forms the basis of this record. Other observers include Annjean Hartogh. | Elimination of similar species: The Petersen guide on p. 170 gives the shape from below and we matched that of an accipiter, not a buteo, and especially not a gyrfalcon. Cooper's and sharp-shinned would be smaller and should show darker tail bands and possibly reddish striations horizontally on the upper abdomen. Also, sharpie usually looks brown-colored. | The original documentation form event lasted from 10:30:00/10:31:00.
