That is interesting- I have several different kinds of feeders out and they use them all.

One thing though, I have 3 first nature feeders hanging from my pc window but one of those has yellow flowers where they others dont. The one with yellow flowers was the least used but it was used just not preferred so I removed the flowers refilled all the feeders with the same amount and all were used equally, you just never know.

The first 2 feeders I have no problem with. The one below is made by First Nature.

No problem with the 2nd one below, but it does have the yellow like the 3rd feeder. Got it at KMart and it is glass. I have no idea who makes this one.

This is the feeder that the hummers will not touch. It is made by Perky Pet. Maybe it's the perch thingy (for lack of a better word).

Is it possible that this third feeder is in a spot where there isn't as much cover to run and hide?

Are you using the same nectar in all three?

I am using the same nectar. I make my own and store it in a plastic container which I keep in the fridge. The first picture with the hummer at the feeder is from last summer. It is in the exact same location where I put the 3rd feeder that they won't touch. I've never had trouble with that location. I've also tried hanging it in my front yard. They just won't touch the 3rd one no matter where I place it or if it's been cleaned and new nectar put in.
