Re: [cobirds] Sound ID

Chip, Jeff, Charles, et al,

Thanks for the great info on the backgrounds of BirdNet and Merlin. I know that these will get better in time. 

Is there a way to let the Merlin-ites know of the false/problematic ID of the Pine Warbler (in my case), so that they can use that feedback to tweak things in subsequent releases?

I ran into Andrew Spencer and Nathan Pieplow out on the Pawnee a couple of weeks ago and Andrew basically said (if I understood correctly) that Birdnet and Merlin were different teams of Cornell etc. researchers working on the same question separately. He said Merlin should be more accurate than Birdnet and will also get better with time. It only recognizes a limited number of species currently and I've had it suggest crazy things way out of range. Eventually it will be amazing and I'm already impressed.

Thanks, Jeff.

I used Bird Net too, before Merlin.  I agree about Merlin's interface being a lot more user-friendly.    I wasn't sure how to do the upload, though, so your email was helpful.

BirdNet says Dark-Eyed Junco, with Chipping Sparrow second, and Flammulated Owl third.  I'll go with DEJU!

Interesting, that BirdNet was (is?) associated with Cornell, too . . . and that they'd give such different results!

I've been using the Merlin Bird Sound app since it was first released in beta. I've found that while it's amazing, I've also seen several false IDs, particularly when there is some background noise such as wind. 

You also might try to upload the audio here, which is the API behind Bird NET, which is an app I was using prior to Merlin (which I've now switched over to Merlin because it's a lot more user friendly).

Also, you might upload your sound somewhere that makes it a little easier for others to view, such as an eBird checklist (which as the ID is in question, upload it as Passerine sp. initially).

COBirders,

Yesterday, I participated in David Hallock's Indian Peaks Breeding Bird Count. My "area" was the Woodland Lake Trail (accessed from Hessie Trailhead, near Nederland). I kept hearing a bird that I couldn't quite identify. It didn't sound quite like a Chipping Sparrow or Dark-eyed Junco, so I thought I'd try the new Merlin Bird Sound app (which is amazing, I must say). Without hesitation, or providing any other suggestions, it identified the sound/bird as a Pine Warbler. Since eBird designates that bird as "rare", I don't want to say that that's what it was, solely on the basis of the call.

I have a recording that I'm happy to share, if someone would like to help me (and Merlin) make the right (pardon the pun) "call".

Thanks so much!
