Another example of the repetitive song, and again the singing bird was displaying to another (May, PA).
On other occasions the song shows much more variety. This bird sang continuously for over six minutes, towards the end dropping down into a bush to sing with reduced volume, at which point another bird emerged from the bush, most likely a mate (May, PA).

The Brown Thrasher has thousands of different songs, each of which it often repeats twice (with Chipping Sparrow calls, May, NJ).
Brown Thrasher whisper song.
This newly arrived Brown Thrasher sang high in a tree then dropped down low into a bush and began singing a whisper song, before rising again to sing the primary song after about 15 minutes.
The whisper song is heard in aggressive interactions or close to a female (BNA). There did not appear to be another bird in close proximity, but another male later began singing not far away (heard in the background of the primary song recording below). There is some mimicry including American Robin at 21s, Ruby-crowned Kinglet at 24s and Carolina Wren jeer at 34s. The bird was only about ten feet from the microphone.
(Blue Jay calling first 20s, 2.00pm, mid-April, PA).
Sonagrams from 23s onwards.
