Sterility of Nectar

How sterile is the nectar hummers get from various flowers versus what they get from our feeders? Has any university ever studied this?

Neither is sterile. I would guess that most flowers are a bit "cleaner" than an average feeder, since most plants that hummingbirds visit only produce nectar for a few days in each flower, whereas a feeder might get a haphazard cleaning every couple of weeks.

When nectar goes bad, hummingbirds won't drink it. That can take a little while: the sheer concentration of sugar makes it a difficult environment for many bacteria/fungi/etc. But sooner or later you'll see and/or smell some changes.
