Tufted Titmice. Their eyes are black as coal & large in proportion to their heads. This not only gives them a ‘cute’, expressive look, it is functional as well.

The eyes placement and high degree of range of movement gives Titmice a relatively wide binocular field of vision. They can focus both eyes on one three-dimensional point within this field, which includes the tip of their bill.

This ability makes them very efficient foragers in the tree canopy and, as many birders know, at feeders. This is helping Titmice counter the population loss trends of many of their cousins. At least a little bit. Their populations are up ~1% since the 60s and their range is moving north as the average temperatures rise.
