Readers’ wildlife photos

We have one submission, today from Paul Handford, and I’ll show part 1 of his hummingbird photos. Paul’s captions are indented, and you can enlarge his photos by clicking on them.

While living in south-central British Columbia, I was so fortunate as to have had close encounters with North America’s smallest breeding bird, the Calliope hummingbird, which weighs just short of 3 grams— about 0.1 oz— and is just over 3 inches long.  Its scientific name, Selasphorus calliope, is well merited:  the generic name derives from ‘selas‘ = Gk. ‘a bright flame’ plus ‘phoros‘ = ‘bearing’, ‘carrying’, while the specific epithet references Kalliope, chief of the muses, and goddess of poetry.

First, the female.  Here are four views of her;  in two you can see that the wing-tips reach beyond the short tail;  in others you see the buffy flanks and faintly-spotted throat (the closely similar female Rufous hummer has a tail that extends beyond the wing-tips, and is strongly rufous on flanks and tail).

Then, males.  The brilliant magenta feathers of the male’s gorget are very obvious when the bird faces you.  These feathers can be erected so as to form a ‘sunburst’ ruff, which males will do when engaged in disputes, and in courtship displays (see below):

The magenta of the throat feathers is produced by the phenomenon of interference rather than by pigment and, as mentioned above, this optical effect is striking when directed at the viewer.  But when seen from the side, these feathers lose their brilliance, often not appearing to be coloured at all:

Many hummingbirds are pretty pugnacious, and often engage in quite spectacular combat.  In these next pics, two males try to impress one another, and the ‘sunburst’ erect ruff is visible:
