BASICS


BASICS: "Hummingbirds.....where is the person, I ask, who, on observing this glittering fragment of the rainbow, would not pause, admire, and turn his mind with reverence..." (J. J. Audubon).
This is a blog about my summer life at the Baiting Hollow Hummingbird Sanctuary, at my winter garden, Calypso, in the Bahamas, and aspects of life in general.
This private sanctuary is ONLY open certain, very limited, dates/times, starting july 20, and ending sept 15, and ONLY by specific private appointment, at particular, available "slot" times posted at this blog. No visits of any type without a confirmed appointment (paul.adams%stonybrook.edu)

white-throated mountain gem


filmed at Sevegre Lodge, San Gerardo de Dota, Costa Rica, feeding on Salvia leucantha. A male - notice the beautiful pale blue patch on the crown at certain viewing angles. 4X slo-mo
San Gerardo was one of our favorite stays - we actually stayed at Trogon Lodge, which is utterly beautiful - the garden with lots of hummingbirds, the various buildings, the rushing mountain stream in a mountain cleft, the little gas fire warming us at night at 7000 feet altitude, the surrounding cloud forest.  The neighboring mountain the sinisterly-named "Peak of Death", reaches 11,322 feet and the pass we ascended before we going down into the valley is at 10,942, where we were definitely short of breath. A couple of days early we were on the Pacific beaches.
Here's another clip at 2X slo-mo

  1. Hey dad, I think they recently split the White-throated Mountain-gem into two species with the White-throated in Panama and the Gray-tailed in Costa Rica. https://en.m.wikipedia.org/wiki/Grey-tailed_mountaingem

  2. Jamie - thanks for raising this thorny question - just what I needed! The Wiki article is interesting, though it asserts that the male cap is green whereas my video clearly shows it's blue (from the right angle). Maybe cyan/aqua is best?
    I am delving into the "splitting" question and might write a blog post about speciation in general. Basically it seems to me that the gray-tail/white-throated split of closely related mountain-gems (Lampornis genus) is not strongly supported by available genetic evidence.
