观察细节
Well aware of the difficulties of distinguishing ravens in Cochise County, I report these as Chihuahuan because of the presence of a nest that may have been a raven nest and would be likely to be Chihuahuan if so. Also, perhaps the recordings are more likely to be examined if assigned to a species. In truth, they are raven sp. The main reason for this report is to make the recordings available. I had been watching this nest all winter while driving my daughter to school in San Simon. I decided to check it at this time. First 3 and then 4 ravens were overhead. I had the impression 2 were trying to exclude the 3rd. Nest was 12 feet up in catclaw acacia. The ravens did not seem to react to my approaching the nest. I saw no indication of its being in use.
