About KOS

KOS LogoKent Ornithological Society was founded in 1952. Our aims are:

To record and monitor the county’s bird life providing both an accurate historical record of Kent’s birds but equally importantly providing data that can be used to help protect valuable habitats from development and other threats.


In doing this, we seek increase knowledge and understanding of birds and their habitats in the county and encourage and support people seeking to take up birdwatching as a hobby.

Membership of the society is open to all and costs £12 a year. Members receive a free copy of the annual Kent Bird Report and regular electronic newsletters.  See details 

The Society runs a bi-annual conference and a programme of field meetings which are open to members and non members and provide an opportunity for both beginners and experienced birdwatchers to meet others and develop their knowledge and birding skills.
