Caught In The Act! -- Red Squirrels (Tamiasciurus hudsonicus); Santa Fe NF, NM, Thompson Ridge [Lou Feltz]
These are both fully adult Squirrels, and I was a little surprised to see them "playing," an activity usually restricted to the pups. Turns out that the "play" was really foreplay... for this following action of ensuring the coming generation. I have seldom observed any Squirrel species in copulation... never photographing it prior! It was a fleeting scene, lasting mere seconds.
