Dear All;
After a quick Google of "Color preference of hummingbirds" it
is inconclusive if they actually prefer red or not and if there are
too many variables to make a determination:
Apparently Hummers may give preference based on season,
quality of food source, color, species of hummer and more. At least
one species seems to prefer green while others seem to favor any in
the red/orange/yellow range.
One researcher says about half the literature says they
prefer red and the other half say 'not so'.
With over 150,000 hits on this topic, I can't say with any
generality except that in my experience I see hummers (and we only
have a single species here) favoring the bright, red, small-flowered
cannas. Apparently other hummers in other situations don't. Duh.
Best Jim W.
