(Incidentally, David Snow says that he has seen other sulphur-belly nests which seemed to be attended by 3, 4, or 5 adults).

Yesterday afternoon, I went up above Sevila, to watch some Bay-headed Tanagers.

The local subspecies is T. gyrola viridissinia (=[[green crosshatch]]////[[/green crosshatch]])
It is quite different from the Panama form, in color. Lacking the bright turquoise blue.

The general habits of these birds were quite reminiscent of those of the Bay-heads in Panama. Forest, or forest-edge birds. Not particularly gregarious. But, according to David Snow, they occur in lowland forest as well as mountain forest.

The only interesting reactions I observed yesterday afternoon were CN's, or what appeared to be CN's. "Seet" Notes. Quite reminiscent of the SN's of Plain-colored Tanagers in sound. Sometimes uttered in series; but not accelerated into CN Trll's

The Snows say that they have heard the local Bay-heads utter a call more or less comme ça: "Seeeee tee tee tee." Musical (in a minor key). Is this the "song" of the local birds???
