Spotted this while on a trip in Yosemite.
Sheesh, there is just NO privacy from tourists.
"Mmmm, love is in the air -- gotta love breeding season."
"Hey guys come check out these mushrooms!"
Apologies for the leaf-obscured photos but perhaps you can look at each for a mental composite view. It would not leave the large tree trunk on the left of each photo, on which it was feeding. It is facing left on each of these photos. It had a small red patch on the back of its head, a white, unbarred belly, barred black-and-white wing edges, and possibly a yellowish/pinkish patch between its eye and beak.
Possibly the same species as my previous observation; this mule deer thought they were very tasty.
Common! Saw a dozen large clumps like this one.
