Following a review by the Executive Committee a revision of the Society’s rules is proposed to reflect changing working practices and communications in a digital age.  For example like many organisations, we switched to on-line meetings via zoom during the pandemic but this is not reflected in the rules. The Committee would like to invite comments and observations from members before the new rules are proposed for adoption at the next AGM.

Comments should be made to the The Hon. Secretary Peter Eerdmans   This email address is being protected from spambots. You need JavaScript enabled to view it.  by 30th September.

The revised and existing rules are attached

 Ray O' Reilly, KOS Field Trip Organiser, writes:- "Yesterday, 19th November 2023, we carried out our monthly KOS Field Outing once again to Dungeness and it proved to be a fruitful venue.

For those cooler days that will soon be here - beanie hats are now available from the online store.  

Merchandise Beanie

KOS is delighted to announce that members can now show their support for the society by purchasing and wearing a range of quality clothing displaying our KOS logo. Whether it is cool or warm there will be something suitable from our new partnership with Kent based and family run company ‘Logo That Polo for any birder wishing to show they are a member and KOS supporter.

There is a choice of garments and a range of colours, all with our iconic KOS Sandwich Tern logo designed by the well-known Kent bird artist – and a long time KOS member - Stephen Message. Using a sustainable sales model, every garment is sourced and branded to order so there will be no unsold clothing sitting wasted on shelving. All order processing is carried out by ‘Logo that Polo and a percentage of the income from sales is passed to KOS.

KOS Chair Andre Farrar: “I’m so grateful to our growing membership for all the support you give to KOS. I’ve often been asked if we could show off our logo on some merchandise – and now we can! As well as making KOS more visible across the county, each purchase helps to raise funds for the Society. “

To view the store please visit or follow the link from the website menu.

Please remember that as every item is produced to order it is essential to use the sizing guides available on the store website for each item.
