Hummer Feeders in hot weather (1 Viewer)

Not the best looking, but when the temperature outside reaches over 100 I either have to move my feeders to shade under the roof eves and have to use lots of precious water (we're on the fourth year of drought) to clean up the bird droppings daily or figure out a way to cover the glass bottles.

For the past five years the best thing I've found is to use a thick foam soda can insulator or a plastic juice container with the bottom cut off to fit over the top of the sugar water jar. Both still aren't perfect but they do help. It takes the hummers and orioles less than 30 seconds to get use to the additions to their feeders.

A good suggestion and most important is to not fill the bottles full of sugar water so you can clean and refill it more often depending on when you're able to do this.

Hummingbird feeders should be placed in the shade, if possible. In the summer I change the nectar every other day, otherwise it will spoil, even with feeders in the shade.
 
Evaporation

If left out too long it will indeed spoil.

In parallel, here in Arizona with our low humidity and high temperatures the nectar liquid will quickly evaporate and soon leave a very sugary goop that will be refused by the birds.

Shade and changing often will result in better nectar for the birds.

I also note that my ant moats/ ant barriers that are filled with water can evaporate in a day or two.
