General   (General discussion, talk about anything.)

Many people are unaware of the legal protection that birds, their nests, eggs and young have and what action they can legally take. However, reckless building work, tree-felling or hedge-cutting at the height of the nesting season can leave people facing prosecution.

Anyone found guilty of an offence could be given a maximum penalty of six months' imprisonment and an unlimited fine, which can be imposed in respect of each bird, nest or egg affected.

Don't carry out any activity that will affect nesting birds in spring or summer when birds are nesting - even if it's just in your garden. Instead, plan work for times of the year when nests aren't in use.
