Be careful when playing the bird songs. A few days ago I clicked on the cardinal song that was in my identification list and the male cardinal nesting in my hedge went NUTS and I’ve not seen either of them since, and used to see them daily. They’re very territorial.

I’m afraid that I scared them away from an active nest by accident just playing around with the app. :(

I have "butt Merlined" a few times...

Each time, I think to myself ... That bird is CLOSE! Let me take my phone out of my pocket and see if Merlin knows what it is ... DAMMNIT!

"Calling back" is a term I heard after getting into birding. I don't think they warn the user in the app enough about "Please don't use this to call to birds, only listen for your own reference".

If I were a bird, and another mysterious bird sound came that was speaking a certain feeling or phrase I could understand, and I come to see it's a giant monkey man playing the sounds from himself, I would probably move my family, too.

Yes, Cardinals are pretty territorial and chase each other out. Esp during nesting.

Whether it's whistling close to their tones, "Pishing" to get their attention, or playing sounds from phones, all of it interrupts their normal behavior. Cars, trucks, lawnmowers, motorcycles all mess with them too.

>When song is played in a bird’s territory, that bird’s response to the “intruder” is watched attentively by neighboring males and by females. In one study (Mennill et al 2002) high-ranking male Black-capped Chickadees exposed to aggressive playback lost status as their mates and neighbors apparently perceived them as losers, unable to drive away the phantom intruder.

It's clear we're capable of mimicking their language with our devices and playing it back to them has potential consequences to breaking up a family of birds.
