While on a local walk several months ago I came across a swallow parent feeding a youngster. The parent hovered and did a mid-air transfer of the morsel to the fledgling on the branch. I got a series of shots of the actual feeding, but the birds' heads were blocking each other, so I thought this was the better shot, taking a nanosecond after the parent made the transfer and began to back off.
