I seem to be having trouble posting on my standard email account, so I've subscribed with a new account, a will try to post this.. -------------------------------------------------------------------------------------------------------------------------------------------------------------------- Anderson County, TN7/31/2012 When you're sitting at home recovering from rotator-cuff surgery, you have plenty of time on your hands (hand?) to do silly things and conduct amateurish experiments. So, I did a test, and I learned that male Indigo Buntings will readily respond to (rush in to investigate) Lazuli Buntings' calls. Sitting on my porch, I played Lazuli Bunting songs from the Audubon Bird Guide app, and Sibley app on my Android device, and several of the vocalizations brought a prompt fly-by from a singing Indigo Bunting that was, initially, a few hundred feet away. I repeated this several times with the same response from the bird. I tried the same experiment with Painted Bunting songs, but to no avail; no response. It would be interesting to know if we see this in other inter-species examples. Thanks. Bates EstabrooksAndersonville, TN SDG
