We enjoy feeding the Hummingbirds and Baltimore Orioles. They both use the same feeder but when the Orioles visit it, the feeder tips slightly allowing the water to drip away. So, I put a post in the ground about a foot deep and nailed a one foot square piece of particle board on top. I then put a small chick waterer on top which holds a one quart jar full of water (upside down).
The next problem was the darned ants coming up the post and invading the the thing.
I tried smearing a three inch wide band of grease around the post but it didn't faze the ants. I tried a little vasoline but that didn't work either.
I then went to the hardware store and got a small container of "Tanglefoot" and smeared a two inch band around the post a few inches below the board. That did the trick. Great stuff and well worth it.
