There have been people over the years that have left their hummingbird
feeders up well into the Fall and have helped straggler Ruby-throated and
even other rarity hummingbirds. Into November, it is occasional for extreme
wandering of species, and hummingbird feeders left up can provide crucial

There are greater forces at play in the mechanisms which trigger migration
than the availability of food at feeders. We understand to some extent
that, on a grand scale, birds which migrate long distances are driven to do
so (or evolved to do so) by the availability and huge disparity
Hi Pete,
Don't worry about either the Hummingbirds or the Orioles. Food
availability is not really a driver in migration timing for any species.
That would be quite maladaptive. Other cues, including but not limited to
day length, sometimes combined with wind direction, atmospheric pressure,
Yes. My concern is that I hear tell keep feeders up for both hummers and
orioles will "trick" them into staying longer than they should.
I've been told this is not a concern for hummers. How about Orioles?
Thanks
Pete

After they've left on migration!
Feeding them isn't going to prevent them from migrating, if that's what you
were worried about.
