A good look at our seven-day-old tree swallow chicks this evening. We’re having a hot afternoon here in West Newbury, the chicks are sprawled out trying to cool off.

The cameras are mounted inside the box letting us watch without disturbing the birds. The cameras have their quirks. They record in color when there’s enough light and switch to black and white and turn on infrared emitters in low light. They’re slow to adapt to the change in light as the swallows come and go.
