[Tweeters] Thoughts on Winter Feeding of Hummingbirds

My second edition Peterson's Western Birds (1961) mentions that Anna's had nested in BC and that some birds were noted north of California so they were moving north in the 50s.

> Most important, to believe that the survival of our regional Anna's hummingbirds (or any bird species) in the winter is dependent upon humans offering/maintaining feeders is very flawed. Where is the evidence to support that belief? As was mentioned in a response posted today, many birds, including hummers, glean small inverts from seemingly bare trees and plants. If you just watch your kinglets and creepers, they expend a lot of energy working the branches and trunks of trees in search of food. They wouldn't do that if they weren't finding inverts. Us humans can't see those inverts, but birds have pretty good search images.

And, I routinely recapture birds that I banded at my house years ago. And, my feeders go dry on a regular basis when I travel.

My answer: if you can't answer that question with 100% certainty, DON'T OFFER probiotics or Gerber supplements in the nectar. I can say with 100% certainty that if you don't offer them, the birds won't be harmed.
