[cobirds] note on Ruby-Crowned Kinglet and Lesser Goldfinch, Ken Caryl and Littleton

I have encountered more Ruby-crowned Kinglets in the southern Metro Area so far this winter (my 4th in CO) than in the previous three, with most time spent in the same general areas each winter. In the past two week I've had 5 in Littleton, Arapahoe Co, and 9+ in the Ken Caryl Valley, JeffCo. One visits my yard most days lately, and there were two in the yard this afternoon. In my prior winters I found them to be fewer and much farther between.

Lesser Goldfinches were sporadic and in 1s and 2s on my efforts in Ken Caryl Valley in November and early December (others maybe had them more frequently at that time), but with the cold and storm on 12/17 they became regular, daily, and in numbers of at least 9 at a time. They are pretty much continual around my home right now. Today I had at least 7 there, plus 5 together in a near by open space corridor and 2 others elsewhere. About 85% are females, but the smaller percentage are brighter and some show flecks of black on the crown.
