Oh how I love those little birds! I have 5 feeders hanging outside the basement window. DH made a contraption that keeps the ants from getting to the feeders, but we have not found anything to keep the wasps and yellow jackets away. I make a half gallon of sugar water every day and fill the feeders daily. I never need to pour any out, those little guys drink every bit of it! I have countered as many as 30 at a time at the feeders, but 2 years ago I was feeding a gallon of sugar water a day so not as many this year. Needless to say, I stock up when sugar goes on sale for less than $2 per 4 pound bag.
