A friend of ours has become seriously consumed with learning and studying bird sounds. He began recording them regularly with his iPhone this past fall and then learned how to make sonagrams of the calls to study them further. When we chatted about the question of whether he might have owls inhabiting the extensive woodland behind his house, he began doing some limited recording at night with his phone.
