A common raven croaks. What a joy to hear those deep croaks, at first a leisurely burst of four, then two more, then two and three and two, if one is counting, then five, then two, and two more, and I always seem to count. The raven then changes its mind, perhaps based on what another raven says in the distance (0:48), for it then shifts to another call, one distinctly higher and of an entirely different tonal quality. He tends to offer three of them at a time, but ends with just one.
It's just a small sampling of all this raven can do.
A distant raven. Warbling vireo, black-headed grosbeak (at end). What is that jumbled song first heard at 0:05, then again at 0:16, 0:27?? It sounds like a Canada warbler to me, but I didn't think that they occurred this far west.
