"New" California Thrasher sings at Ulistac

We now have 2 Thrashers at Ulistac! For those who know our original Thrasher (who has been with Ulistac for several years now),his song is quite distinct. He imitates the other birds in the area and sounds a lot like a Mockingbird much of the time, even imitating things like car alarms. I have listened to this Thrasher sings several times now and his/her song is nothing like the other Thrasher's. As he sang, the other Thrasher was just across the way in eye shot also singing from a tree top. I believe they are both males, however, so unless there is a female around as well than they are both out of luck. It is possible that there are more than 2 but I can only verify the 2 as of now.
