HI For the last month or so my garden has been infested with flies with long legs that hang below them when they fly, now i have a flock of about 100 birds sitting in the trees attacking them will they kill them off naturally or will i need to do something to kill the flies off

Got any pictures, or a better description of the flies? If the birds are eating them, then you've probably got nothing to worry about.

Almost certainly a description of St Mark's flies...so called because they emerge around the time of St Mark's Day every year ( 25th April ) I wouldn't worry about them....just one more link in the chain of wildlife, giving your local birds something more to eat !
