While swallows are definitely cool birbs, I would be very surprised if they had any noticeable effect on mosquito populations. There is even one study proposing that swallows attract more mosquitos!

Well, these are barn swallows. They eat up to 1,000 insects per day, and up to 100 mosquitos per day (link below). We have at least a dozen, so perhaps 1,200 mozzie per evening (I hope). I think barn swallows are the most populous bird species. Again they are pretty cool. We also have lots of bats, but they are harder to track. HTH, RF.
