When our good neighbor Mike came down the driveway hill for a chat the other afternoon, I noticed a dusting of yellow powder on the front of his tee-shirt, in his beard, and on the side of his cap.
"Been doing yard work, eh?" I said, and grinned at Mike's puzzled look. I pointed at the yellow sprinkle. "Pollen. Hummingbirds visiting my bergamot have it on their heads. Y'all been poking around the same bloom patches."
I'm not sure which neighborhood flowers accounted for the golden-yellow pollen, but my first guess would be lilies. Lilies are a good candidate since the blooms have deep throats and long, protruding anther-tipped stamens holding yellow pollen. A feeding hummer has to shove it's head smack past this pollen dispensary in order to sip nectar—thus becoming an inadvertent pollinator, while ending up wearing a gold crown.
I've been making a lot of hummingbird photos recently. Many of the tiny birds I'm currently seeing have pollen on their topknots. The shot above is an enlarged crop taken from another image, which itself was a slight crop from the original full frame. Quality is a bit on the "noisy" side. But otherwise, a decent portrait of a golden-capped ruby-throat hummer…or maybe just of a bird needing a bath.
