The results don't surprise me. I've had Merlin lie to me on a number of occasions, and fail to pick up a bird close by that I can hear clearly. This seems to be especially true of Brown Thrasher. The same thing happened to me with a Bullocks Oriole last Spring in New Mexico.
Nevertheless, it's still a useful tool.
