Andrew Spencer and I got in some decent birding in Park County before the rain started this morning. The highlight was a breeding-plumaged Red-necked Grebe at Antero Reservoir. We also saw a trio of Hooded Mergansers at Eleven Mile Reservoir.
On the way home we headed north from Woodland Park. In Douglas County we found a large flock of dozens of Evening Grosbeaks -- family groups with adults and lots of begging young. It was really interesting to see how the juvenile plumage of males differs from the juvenile plumage of females -- it was quite easy to tell them apart. Neither of us had ever heard or recorded the begging calls of the species before. Most renditions sound like a lower, softer, finer version of the trill call of adults. Happy birding, Nathan Pieplow Boulder -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
