Number: 10

In the past week, more calliopes have arrived at this location. I'm providing one picture of a "drinkathon" of some 6 birds at a 10-hole feeder at dusk (taken through a window), although this picture under-represents the actual numbers. As best as I can observing flying, darting and hovering birds getting their last energy before sleep (picture taken around 8 pm PDT), I am estimating there are about 6 female calliopes, 4 males, two rufous females, and one male rufous (the first hummer arrival this year on 8 April, all by himself for about a week) visiting my feeder throughout daylight. At dusk, they all are frantic for sugar around the feeder, and the calliope males also take opportunities to court females with paired twirling - purple neck feathers extended - and diving displays which at the nadir of the dive end with the characteristic "zing" to attract the female.
