Two behavioral notes from Natural Bridges State Park around 11 am this morning. First, the five-minute-long effort of a HUTTON'S VIREO trying to keep up with a pair of excited, vocal, crest-flashing RUBY-CROWNED KINGLET around the eucalyptus near the bed of the creek crossing the loop trail near the park's Delaware Ave entrance. The difference in speed was even more evident than the differences in bill size and wing pattern.
And earlier, in the trees along the entrance road above the creek, a HAIRY WOODPECKER faithfully following an apparently (anthropomorphism alert) mildly irritated DOWNY WOODPECKER from branch to branch -- again, for a good five minutes before both birds flew out of sight. Instructive to see the enormous disparity in size -- I had no idea.
My guess would be an immature in each case following adults on a first migration.
