Not Quite

Cactus wrens are huge wrens but this fellow's mouth isn't quite wide enough to pick up the inviting peanut.  They usually knock them off of the wall and peck the heck out of them; their bills acting like tiny jack-hammers until the unencumbered nut pops out.   This fellow must have a 'big bird personality complex'.   {I got that from the DSM-5}   :-)
