“… like underwater blood hounds, sea turtles that feed on seagrass can lead researchers to the meadows far more reliably than satellite images, a team of marine ecologists has found.”

One American White Pelican had the fish, and the rest arrived like they had been personally invited to help “supervise” the swallow.

Green grass, scattered rain, and a Bald Eagle making use of every last piece. Survival can look surprisingly efficient.

"Sunny wings"
I came across a mob of Cedar Waxwings who seemed to be eating flower petals from this apple tree. Anyone know if this is a known behavior?
