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?
