I put out Oriole and Hummingbird feeders last week.  I still have not seen either, so I guess I will make wash the feeders and put out new nectar.

Oriole nectar is 1/4 cup sugar with 3/4 cups boiled water.  I mix mine in a mason jar for easy measuring, cool before putting in the feeder.

Hummingbird nectar is 6 to one, so 1 cup sugar to 5 cups boiled water.  You can keep it in the fridge if you have extra.  Lasts about a week.

Disinfect all feeders with bleach and rinse well between new fill ups.
