Aggressive housing developer & Loud Bird scarer

I am new here - Hi! I was hoping to find some advice or pointers. I have moved from town to a village a year ago and noticed that there have been very loud bangs with plumes of smoke from the field near us but only recently. I guess it is a bird scarer but it does seem extremely loud. We have an aggressive housing developer shown interest in putting loads of new houses on the field and have been known to run rough shod over other villages & gone ahead despite villagers and local councils all opposing. I was wondering if they are trying to get rid of protected birds/animals before a planning application goes in. Is there any advice anyone can give how I could check this out? We dont want the houses and we have spent the last year attracting all sorts of birds to our garden too & want to keep them - so double whammy! Thanks :)
