Looking at the wildlife pics, it seems to me the eyes are very expressive.
Cooper's Hawk is focused on something of concern - food or otherwise.
The Moose is clearly a bit of a "are you sure you are to be standing there" type of look to me.
The northern flicker is like some grand dame "oh young man, if you must" type of look.
The junko seems just bored with the whole effort.

really like the grand dame flicker look.

Just my two pennies.
