Observation details

A perplexing bird. Heard at first, and immediately noted different call note quality than pawr (I had seen and recorded another typical pawr 5min prior to finding this bird). The call wasn’t a perfect match for wiwr from my experience with them out east, seeming a little too metallic and not “chimpy” enough. Visually the bird was rather pale in the face and breast, with an extensive pale supercilium. Flanks were intermediately barred, within the range of pawr. Visually I think this bird is within the range of pawr, but sounds a bit off. I took many recordings of the calls, and played both wiwr and pawr. It seemed to respond pretty equally to both, perhaps a bit more strongly to wiwr chatter call. My impression in the field was that it was possibly a funky HY pawr still learning its calls, until it started giving a rattle or chitter call. I cannot recall hearing a pawr give this call before, but I HAVE heard wiwr give a similar call. I got good recordings of this call, as well as full frame photos of the bird from multiple angles. I suspect no definitive consensus will be reached on this bird, and I will need to do some more research when I get back to my computer. This seems to be a weird tweaner bird... I presume hybrids do occur in NE British Columbia, and this could very well be a good candidate for a hybrid (which would be pretty neat!). Very vocal on the ne part of the wildlife area near the river, here (48.0807835, -119.7226568). I have many more photos, email me if you'd like other angles. For reference, here is a comparison of the chitter calls of: pawr: https://macaulaylibrary.org/asset/392340641?_gl=1*1u9i2da*_ga*MTMwODY5ODU3OS4xNjM1ODg3MTIz*_ga_QR4NVXZ8BM*MTYzODU5NTkyMi42LjEuMTYzODU5NjI5My4yNQ..#_ga=2.112048196.1116989677.1638593754-1308698579.1635887123 wiwr: https://macaulaylibrary.org/asset/392969471?_gl=1*fay3cv*_ga*MTMwODY5ODU3OS4xNjM1ODg3MTIz*_ga_QR4NVXZ8BM*MTYzODU5NTkyMi42LjEuMTYzODU5NjI5My4yNQ..#_ga=2.70637392.1116989677.1638593754-1308698579.1635887123 https://macaulaylibrary.org/asset/194963381?_gl=1*a7pujo*_ga*MTMwODY5ODU3OS4xNjM1ODg3MTIz*_ga_QR4NVXZ8BM*MTYzODYwMTU4MC44LjAuMTYzODYwMTU4MC42MA..#_ga=2.74905682.1116989677.1638593754-1308698579.1635887123
