Hi! OK that's good to hear. In Portugal it came up with false positive detections of Hawfinch and Little Owl. Both those species were present in the area (saw them!), but if you think about Hawfinch in particular, it has such a nondescript vocalisation (a quiet, short monosyllable) that it is really easy to imagine that it could be spuriously identified by the neural network (after being allowed as an ID by a prior/filter based on the species plausible in that geographic area at that time of year). I don't mean to sound like I know about the details of their neural net and classification algorithms, or like I know how to do better, but I do suspect that it will improve with some tuning to essentially make it demand stronger evidence for a call like Hawfinch. Little Owl is a bit more distinctive, but I don't really think one was calling when it said it was. I think it also spuriously identified Blue Rock Thrush, but maybe it was right and we just failed to hear/see one! The habitat seemed right. I haven't seen as many misidentifications in Eastern US (a couple of days ago I did think it said Kentucky Warbler for an Ovenbird).
- tiagod 4y agoI've had the same issue with little owl in Portugal (just yesterday). I believe it had to do with missing songs and cicada interference in my case.
