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. Other documentation forms by Jim Sinclair, Stephen Dinsmore, and Jim Fuller were submitted later. Other observers include Rick Trieff and Jane Fuller . | Elimination of similar species: The only species this bird could be confused with is Common Redpoll. Two individua |

| Event Remarks |
Viewing Conditions: I looked out the window to check feeders at approximately 7:30 AM and saw a Common Redpoll on the niger feeder. It was soon joined by another redpoll which was much paler in comparison to the first. The overall effect was that the bird was extremely washed out. The niger feeder is 20 feet from my utility room window. The bird returned to this feeder throughout the day while at other times it could be seen in the snow below the branches of a willow roughly 60 feet from the house. I set the camera on a tripod and was able to get numerous photos of this bird and two distinctly different Common Redpolls. At times the three birds were at the feeder together allowing for great comparisons. |
