Field Frame Friday: A whole new meaning to being called a “bird-brain.”
While the idiom, “bird brain” may mean a silly or stupid person, we may want to reconsider it as a compliment.

Whatever its true…
Field Frame Friday: Mistletoe Munching
Mistletoe does not only serve to incite smooches on Christmas, but it’s also a tasty snack for Diademed Sifakas (Propithecus diadema) in Madagascar.
