Last week I emptied my feeder ( for the first time all season ) . I had filled it with commercial nectar , it was red . Directions on the box said that because it contained preservative it did n't need to be changed as often . The birds came to it but not so frequently ( hence the fact that it was n't even empty when I took it down to change it ) .
Question: Why did the birds come to it ?
The answer to the above question:


They were hungry and wanted to eat .
