House finch or not?

[Ann Donoghue]

Hi,

I have in my yard what looks like a male House Finch.  However, its song is driving me nuts.  It starts out with only a few of the warble-y notes of a regular house finch, but then always (ok, 95/100 times) ends with the same exact 4 notes, at an even pace, and they are just the tiniest bit buzzy.

If you know musical notation, the notes are A-F-G-A.  Every time.  I can replicate it on my piano.  

Is this normal?  I couldn't find any recording of any of the finches (Cassin's, Purple, House) that do this same thing.  

Do I just have a musically talented House Finch who sings non-stop?  That's the other thing, it's more incessant than the Eurasian Collared dove.  And it is still singing even though all the other House Finches are mostly quiet.

Any thoughts would be greatly appreciated!
