Evening Grosbeaks are a puzzle to me, being nearly gone from my area for years. I think I've had them at the feeder only once or twice the last several winters. Back in the mid 70's they were very common at the feeder, especially when we used sunflower seeds. They were gluttons that would swoop in by the gob and devour the mornings offering in about 10 minutes. As for the Hartwick Pines reference, I have to add that the last two times my Bride and I went there(those trails are ready-made for her power chair!) we saw Evenings at the feeders outside the visitor center.
