Avid birder Kelly Asada has reported swarms of hummingbirds at her feeder since temperatures have reached the high 80s. She currently makes nine cups of nectar a day to keep the hummers happy. Hummingbirds appreciate extra fluids in hot weather. Use a 4:1 ratio (4 cups water: 1 cup sugar) when making homemade nectar. It's OK to weaken the sugar solution a bit in hot weather. Never use honey or red dye! Both are known to be bad for the birds.
