The warming effect of climate change is predicted to be most pronounced in
the continent's interior, not at its coasts. In southwestern British
Columbia, one is hard-pressed in winter to find an Anna's Hummingbird that
is not within a few hundred metres of a feeder. I think that there is very
much to be worried about here. What we observe and attribute as
consequences of our actions is not necessarily all that occurs as a result
of them, the actions in this case being the planting of winter-flowering
non-native trees and shrubs and the supplying of sucrose solution at
feeders. And just because there is no apparent competition, hybridization,
or inter-species disease communication now, does it mean that there will
never be? Natural selection is occurring as we speak. And what happens in
1,000 years? Are people going to be feeding and planting for hummingbirds
then? What will be the values and goals of humanity then?
