[cobirds] Rufous Hummer behavior, NW Custer County

COBirders— Yesterday two male FOY Rufous Hummingbirds showed up at my feeders more or less on migration time. They followed the usual behavioral pattern of vanguards in that, rather than exhibiting their species’ normal activity (i.e. bellicose copper-colored buzz-bombs), they fed amicably alongside the broad-tails.  Soon they will move on, to be replaced by more typical male Rufous hummers.

   As an aside, we had a pair (m., f.) of Calliopes three weeks ago—for one day only—unusually early for our location. The Broad-Tailed hummers are present in about their regular numbers, about 30+. We are seeing a few fledglings now. In case you are wondering, we buy sugar in 25-pound bags.

  Our cabin feeders are at 9,200 ft. in the Sangre de Cristo range.

Leon (and Treva) Bright, Westcliffe / Pueblo—not so much
