Winter Wren

Troglodytes troglodytes - Uncommon; in brush piles or thick undergrowth in moist forests. A very short tail, bobbling action, and a dark brown barring on the belly separate this bird from the larger House Wren. Not the inconspicuous eye stripe. Song is a rapid succession of very high clear notes and trills; it lasts about 5 sec. and is repeated 4-6/min. Low double call note, tick-tick, is distinctive.
