Probably a Black-chinned Hummingbird, though several less numerous species may show up in the area as well. http://www.allaboutbirds.org/guide/Black-chinned_Hummingbird/lifehistory http://www.allaboutbirds.org/guide/Black-chinned_Hummingbird... > When newly built, the nest is a compact, deep cup constructed of plant down, spider silk and cocoon fibers. As the nestlings grow, the nest stretches into a wider, shallower cup. Nests from cooler areas are thicker-walled than nests from warmer areas. > Most Black-chinned Hummingbird nests have been found an average of 6 feet and at most 12 feet above the ground, but this may be because nests at this height are easier for observers to find. The nest is often on an exposed small horizontal dead branch well below the canopy.
