Hello Fellow Birders,
A Black Grosbeak has been hitting the cup of peanut pieces in my little townhouse yard in west Centennial, near Holly & Arapahoe. I'm guessing it's a first year bird, though I can't tell them apart from adult females.
Also, I started seeing an adult Chipping Sparrow (never saw two) around my yard in early- to mid-June. About 2 weeks ago I observed it several times in my front lawn and each time it was collecting small insects. It would then fly up into a large silver maple tree. About a week ago I watched it collect bits of seed from under the feeders. It then flew into a dense crab-apple tree from which a din of chips then erupted - it was feeding fledgling(s). A few days ago I started seeing Chipping Sparrows with streaky breasts (kids) foraging under the feeders.
As for the flock of crossbills that graced my yard with their presence for a couple of months, they have moved on. I took down the feeders in mid-June because I was seeing sick House Finches, plus I was going to be out of town for a couple of weeks. Haven't seen the crossbills since.
