Hey Mike, There is no such CD that you refer to. Would appreciate it you could refer to both authors or simply the Flight Call CD (at least until someone else publishes a flight call cd).
Regarding Harris' Sparrow flight call, I suspect they would be in with your Song Sparrows if you have them. The sample size we had to work with for the CD was small, only a few individuals, so perhaps there is substantial overlap in frequency with Song -- the shape of the call certainly looks similar.
