If you live south of the 40th parallel, Evening Grosbeak is something of a mythical bird.  In 36 years living in Stillwater, OK, we've had a flock of these northern birds exactly one time.  They are irruptive, appearing out of nowhere, lingering for a short while, then vanishing again. 
   But at our New Mexico cabin, high in the mountains at 8000', Evening Grosbeak seems more at home.  In early April 2010, we had two, then four males at the feeder.  On the day we left (too later for a photo!), the pines were alive with the twittering of both males and females.  They use ponderosa pine for nesting and foraging, so perhaps there we'll have a few of these handsome birds year round.
