Wrentit - Extended Trill
The male Wrentit song consists of a few sharp whistled "pit" notes with a descending 3-4 second trill at the end. It is considered the classic sound of the Coastal Sage Scrub community. This week I hiked up Hazard canyon. Wrentits were active and singing. One Wrentit was defending his territory of blooming Hemlock from a persistent Anna's Hummingbird. Every time the hummer hovered over a blossom, the Wrentit chased her off.
The video consists of three segments. The photo of the Wren separates the segments. For comparison, the first and last segment are the usual song with a 2.83 sec. trill. The middle segment has the extended 9.13 sec. trill. When you are watching the video keep in mind that, as he trills, his tail is vigorously vibrating. https://youtu.be/-pBjwCYZUwM
