Just three years ago rufous hummingbirds were plentiful in spring in my
neighborhood. Every 150' or so, they'd occupy the prominent treetop. Three
years ago was also when we started seeing Anna's H-birds in winter, and
subsequently in spring. The Anna's population is so great now that this
bird that was non-existent a few short years ago is now the most common
neighborhood bird besides chickadess. Now I notice just one rufous h-bird
keeping a territory. Just wondering if anyone else has had a similar
experience. I was under the impression that Anna's would lose out in any
territory squabble to the uber-aggressive rufous. Maybe that is still true
but perhaps there are other factors in play?
