So I have the iBird app on my phone and iPad and got a little curious one day. A while back I reorded a Cooper's hawk making a call and realized that's its dead on to the audio sample from the app. So the other day a coopers flew overhead and off toward the woods adjacent to my property. For the hell of it I pulled out my phone and played the sample from the app as loud as I could. I'll be damned if only a minute later the hawk flew right back and perched on a tree right next to my house. I slowly approached it playing the call, only to have it returned right back to me. We went back and forth for about 15 minutes, as I'm snappin away right underneath it. I was shocked as every other encounter I've had with them is very short with them flying off the minute I get close for anything decent. Since this has happened it's worked 3 other times, all of which it let me get right under its perch and didn't care. Just curious if anyone else has tried this with success. My only concern is the call is labeled as an alarm call and if that's true I'm wondering if its stressing the hawk out. Only once has it flown off with me approaching so it doesn't seemed stressed but rather curious. The one day I ended getting 3 to come right over my house, 2 of them flying together. If my neighbors didn't already think I'm a nut, they do now!
