|Laser-bright mouth, "Put food here!" it says. But Ma and Pa Swallow are taking a short break.|
I noticed that, although the youngsters seemed to be yelling, and I was only a few feet away, I couldn't hear anything. It may be that while the parents were resting, the chicks were only practicing their gape, or that their cry was beyond the range of my aging ears. Audubon has a recording of the chicks' begging cry, here. (I can hear this fine, even at the lowest volume.)
|Two chicks, two parents.|
|Chin feathers like one of those rubberized hairbrushes.|
They grow quickly; by now, they'll be trying out their wings.
