Winter Wren in the hand

These tiny balls of energy are sometimes referred to as mice with the way they scurry around the forest floor. During the breeding season, males will sing one of the more complex songs out of North American bird species. Each song lasts 5-10 seconds and consists of unique bubbly notes which the individual will combine and modify over time.  

Like other wren species, the Winter Wren characteristically holds its tail straight up – except it is incredibly tiny at ~29mm! For reference, while the Winter Wren is twice the weight as a Ruby-throated Hummingbird, the hummingbird can have a tail a similar length!
