	FIGURE 1. The bird is an adult male with a full gorget that is a shade of purple between the colors of male Calliope and Black-chinned.
	FIGURE 2. This is picture of the top of the head and back of the bird. Measurements (in mm): Wing - 40.1 Tail - 24 Culmen - 16.1 Grooving - 0 Gorget Feathers - Full Weight 2.8 grams with 0 fat Molt - none
	FIGURE 3. Picture of extended wing. P-10 has the definite shape of a Black-chinned hummingbird.
	FIGURE 4. R-1s are "semi-spatulate".
	FIGURE 5. Rufous edging on the rects and length (24mm) are right for that cross.
Size, shape, and weight (2.8g) all point to a BCHUxCAHU hybrid. Those two species are also the only ones known to breed at that location. I banded females of both species with eggs.  I also banded a female at that location that is a possible BCHUxCAHU hybrid, but of course the differences are much more subtle. I took a feather sample of that bird for DNA analysis.
