[Tweeters] chestnut sided warbler

[Faye McAdams Hands]

My experience is similar to what has already been mentioned.
I did want to add though that it (Merlin) does learn by "experience", so it is important for us to add comments, especially when we disagree with an ID given.
It takes a village.....

Definitely, visual confirmation is needed on any hit on chip notes or contact calls. Lots of misses there. On Kevin’s question, it depends on what it thought it heard with respect to the “chestnut-sided”. Did it pick up a song or subsong segment? If it was just a contact call or chip, then I bet there’s not much you’d be able to do with it even after analyzing the sonagram. That’s been my experience.

I've also experienced Merlin misses, but what do folk suppose was the purported Chestnut-sided Warbler in this case?

Merlin has told me several times about the chipping sparrows in my yard when I know it's hearing juncos. I wouldn't trust it on an out of area bird without a visual confirmation. It's impressive technology that it works as well as it does, but perfection would be too much to ask!

I ditto Penny’s experience. I’ve been using Merlin quite a bit since my hearing is poor, but I always check it by simply replaying the recording, sticking my phone’s speaker in my ear if necessary. Or by analyzing the spectrograms/sonograms at home if it picked up something really odd - yet possible (it’s tricky learning how to export the recordings off your phone at first).

But, yes, even after you make sure the App is location-aware (you’ll know since it will display your location when it’s recording), there is still something in their algorithm that has it try to match sounds to birds not documented for our continent and the “hits” are frequently European birds. Quite strange. There might be a bird pack filter option I’m not aware of or they need to fine tune their logic a bit.

Merlin isn't always 100%.  I had it come up with a Yellowhammer in New Mexico a few months ago!

Today I was birding at Twin Ponds Park in Shoreline, using Merlin.  Merlin picked up a chestnut-sided warbler.  I neither saw nor heard it myself.  Has anyone else encountered this bird?
