I'm very pleased with the course so far - I've been wondering about a specific bird that has been at my feeder the last week and after downloading the free app recommended I was able to quickly determine that it is a tufted titmouse! I'm in upstate New York and have a pair of cardinals that visit our feeders every day. There's a solo male that shows up while they're there and the males puff their feathers until one gives up and flies away. I think I watched the bird of paradise video three times - so fascinating! Excited to learn more!
