I have always thought Purple Martins (you know the birds that live in the hollowed out gourds) ate tons of mosquitos! Recently on a trip to Plum Island National Wildlife Refuge I spotted someone carefully cleaning the Purple Martin nests. After asking her multiple questions, I learned a lot about these beautiful birds. They DO eat mosquitoes but that is only about 1-2% of their diet. Purple Martins feed mostly on dragonflies! They feed on the fly, meaning they eat and catch food while flying. Mosquitos typically live close to the ground. The Purple Martins don't fly at night which is when mosquitos are active. I was certainly surprised to learn this fact. They are extremely acrobatic, beautiful birds and I have come to appreciate them much more even though they don't really eat mosquitos.
