Observation details
Audio recordings are of two separate American Crows. Both were perched together in a tree not more than 50 feet from me. I recorded for about 5 minutes. For most of the time one crow called and then the second crow with the higher voice called for about a minute or two before they both flew off. I separated the recording into two files in order to separate the recordings of the two birds. They seemed to be calling to other more distant crows. The more distant crows called back but I'm not sure they can be heard in the recording. One crow had a higher voice than the other. Recordings were made on an iPhone with the RODE Rec App and edited (Normalized and High-Pass Filter) using Audacity.
