tufted titmouse

Across North America,  a common choice
At home in a mob
Little gray bird with an echoing voice
flitting through twig ends  in a dive-bomber bob.

Attracted by others calling you out…. 
PETER-PETER-PETER .
Large black eyes, small, round bill, a little stout
peter-peter-pete, an eleven-time repeater
. 
No ascending trill goes unmatched 
 songs  at dawn with no moratorium
From you nest wall’s little hatch,
 used-up notes repeated ad nauseum. 

Flitting through the canopies
Your brushy crest is a noble shroud.
Not to be confused with common Chickadees.
 performing acrobatics in an unruly crowd.
