Friends:
Walt's puzzle about phrases from a Mockingbird (what is it imitating?)
is a context to let me mention one of my out of the way projects which
is to record birds singing songs that they shouldn't. A NoMo supposed to
sing other bird's songs.
But a Towhee that sounds like a Blue Jay or (in the example below) a
House Finch that sounds like a Northern Cardinal is doing something
unusual. I suspect that this sort of thing is caused by a young bird
learning its song from the wrong adult. This sort of thing could happen,
for example, if nests of 2 birds are nearby and the male from one nest
removed from the area (eg dead).
The HoFi/NoCa example is at=20=20

I'd be interested in hearing or hearing about any similar examples
you've encountered.
Cheers!
Steve P
