thank you very much for this reply and appreciate your detail to the Tweeters' post.

This feeder (Nov 14 at 16:46 has 3 portals - the adult male was perched at a regular wire next to the feeder with three hummingbirds nectaring simultaneously at the feeder.

Interesting Tweeters post Re: Anna's Hummers in Fall (Winter?).
Here are some observations down south in the Portland Area
Click on the image to get the idea.
Some follow ups; I'll summarize.
In addition to the feeder shown in the photo, My son had a 2nd feeder 10' away. The one in the photo went empty daily (no surprises) while the one 10' away never went empty. Why? It was guarded by a male who kept the hoards at bay. As an experiment my son moved the guarded feeder 5' closer to 5' away. The guard hummer gave up and now the hoards occupy both. How many hummers can share a feeder at once? There are 7 holes, so 14 hummers. They take turns, like some sort of automaton. Anna's hummer behavior is pretty complex.

PS Sorry to keep harping, but this post was made simple by allowing photo(s) with an OBOL post. This allows the photo to be stored in the OBOL archives, which happens without any effort on the part of the local OBOL administrator..

Hello cj,

An additional thing to consider.
Here on Mercer Island we have found that Anna's are much more tolerant of others at a feeder, especially near dark and last feeding, when temperatures are very low.
What was the approximate temperature when they were all on the feeder?
