We are a small, not-for-profit volunteer group making nest boxes for garden birds, raptors, swifts, hedgehogs and bats. We sell our boxes at cost price.


BNBG is a voluntary group established in 2014 to encourage the population of Barn Owl and other declining species in our area, but we now make a big range of different types. We are a Charitable Incorporated Organisation (CIO), Reg No 1166818. We are based near Bisham, Berks. All our boxes are sold at cost.

Group at work

In 2015 we were approached by a new local bird conservation group The Maidenhead Marlow and Cookham Swift Group www.helpourswifts.org.uk/ who started an initiative to provide nest sites for endangered swifts in response to the demolition of a Maidenhead hotel .......


We will be holding an event at Braywick Nature Centre on Sunday 27th January 2019, in partnership with Wild Maidenhead, where you will be able to see and buy our range of boxes for garden birds, barn owls, tawny owls, little owls, kestrels, robins, blue tits and great tits and swifts, hedgehogs and bats.

Get Involved

We sometimes have vacancies on our small team for anyone with some level of DIY skills. We meet weekly on Wednesday mornings, weather permitting, at our building base in Winter Hill Road, Cookham. Please contact us if you are interested.
