I live at 7700 ft between Conifer and Evergreen, and, atypically for the eight years I've lived here, this year I've had PISI regularly throughout the winter. What has surprised me even more is that I anticipated that they would move on to higher elevations (or lower elevations, as Dave suggests) once we were getting into more springlike weather. However, in the past two weeks, the opposite has happened. Currently, I regularly have 25-30 PISI on a daily basis, and following our one somewhat significant snow event in early May there were about 50 around for a couple of days. They tend to be feeding voraciously, and seem to be relying on my feeders as a significant resource. I take my feeders in every night, and they and the BTHU are always waiting for me to emerge at the crack of dawn. I get intermittent visits from 6-12 RECR, but they are not the daily swarm that the PISI are.

COBirders-- As I reported several days ago, Red Crossbills are visiting my back yard regularly, ranging from four to seven birds at a time. It's odd that they would stick around after not having been here before during the 47 years we have lived here. Also, the flock of 12 to 15 Pine Siskins have been snarfing Niger (aka nijer, thistle) seed continuously for about six weeks, much longer than this species has stayed before. Why would these irruptive species stick around this year? Soon I will be off to the mountains to check on the cone crop, related to the crossbills. Could the drought be the cause of the siskins' extended visit?
