Bird Buddy notifies you of feathered visitors, captures their photos and organizes them in a beautiful collection!
Just seen this, massively supported, Kickstarter. A simple concept, camera on bird feeder but with auto id and linked to an app. Good for surveying what visits your feeder. A video doorbell for the birds. Wandering round Tescos and your phone goes ping, "oh there's a nuthatch on the feeder".
