How will this affect birds and other creatures that eat mosquitoes? More info , please.

Our bay lands are among the nations' great sites for marshland bird watching. Eco systems are complex and delicately balanced. What does this mean for the marshland ecosystem?

To answer to the "how will it affect our birds" question, It will benefit them.
The mosquito population is being treated because of West Nile virus, which also infects humans and birds. It has been known to infect birds and cause death. I repeat.. death and infections in birds.

As if that is not bad enough, the West Nile can cause serious illness in humans. Extremely serious effects of West Nile include meningitis and meningoencephalitis. So before you assume decreasing mosquito population is terrible in a preserve, realize this would not be done unless absolutely required.

So treating mosquitos so all birds and humans can enjoy the beautiful preserve is a great thing. PSA: get rid of your standing water in your yards - it breeds mosquitos as well.
