John and fellow friends of birds- have you found the app “Merlin Bird ID by Cornell Lab”? The app guides you to download the calls of birds most often found in your area, then while sitting out on the deck or taking a walk, you tap on the app microphone and it starts recording calls, then pops up bars with photos of who you are hearing, you can then tap the bar for further info. Over several walks, I’ve come upon 17 different ones!! You also have the choice to relay the info to Cornell Lab of Ornithology, which uses the data for their ongoing studies. It’s fun!
