This reclaimed gravel pit is now a marsh teaming with wildlife...and mosquitoes. But, along with the mosquitoes come all varieties of birds, fish, and bats who feed on the pests. Even though we may not like mosquitoes, they serve a purpose in the food chain. Unfortunately, our use of pesticides has an effect on the chain because the animals that feed on what we consider pests end up poisoned from eating a bug sprayed with poison. American kestrels, the smallest hawks, are in decline because they feed on smaller prey that have eaten pesticide sprayed bugs or have been directly effected by the pesticides themselves. Bees are inadvertently dying because they are an insect and pesticides don't pick and choose the "good" bugs from the "bad" bugs.
