Northern Mockingbird - the Ultimate Mimic

I'm sitting here watching a male Northern Mockingbird "singing" in the pine tree under which my car is parked. The hilarious thing is and this is why I put "singing" in quotes....one of the "songs" he is doing is a surprisingly clear and accurate imitation of the cell phone ringer on my neighbors cell phone! I didn't pay attention to him at first until it dawned on me that the frequency of the cell phone ring was way too slow for a normal phone.

I remember once in July 1983, in a friend's backyard in Laurel Maryland, we listened to a Northern Mockingbird as it sang the songs of 34 different species including a Western Kingbird. However this is a first listening to one mimic a cell phone.
