媒体文件注释
calls from a group of five birds (which included the pair from ML33236491) perched on the tops of tall spruces in fairly open Black Spruce muskeg. These calls were given apparently in alarm to my presence, and there were two female Pine Grosbeaks giving alarm calls at close range to me at the same time. In this cut there are several whistled 'seer' calls from a female bird, in addition to the normal long trill from several of the birds, and a few of the shorter, higher-pitched, quieter trills from several birds.
