pameladean pointed out this Song Sparrow hopping around in a stand of sumac. Looking at it in the viewfinder, I thought it had a piece of nesting material in its beak. When I zoomed in on one of the photos I'd taken on the camera's LCD screen, the "nesting material" turned out to be a Dusky Clubtail dragonfly, minus wings. I doubt a sparrow could catch a dragonfly out of the air, so it had probably found a recently-emerged one in the grass. Those photos didn't come out very well because the spotted brown dragonfly was hard to make out against the spotted brown sparrow. Luckily, the bird's next catch was a green caterpillar, which shows up much better. I suppose the bugs were destined to be baby food.
