A variety of research programmes are carried out at Kartong.

Spur-winged Plover

Specific studies presently include leg flagging Spur-winged Plover thus allowing us to identify individuals in the field. This enables us to not only follow individuals dispersal from the site but also the breeding biology of the pairs that nest here.

Hooded Vulture

Hooded Vultures are also being ringed with Yellow alpha numeric colour rings and wing tags which allow us to identify individuals as they move around the area. Vultures are suffering a population decline in many parts of the world and as they play an important role in the environment. Data collected now will help our population monitoring.

Several Bats are caught as incidentals when opening and closing the nets. Yellow Winged  Bat are commonly seen in the morning and a Gambian Epauletted Fruit Bat was caught at Lemonfish.



The Osprey is one of the most spectacular birds at Kartong. Many spend the winter in our recording area and we actively follow birds to identify individuals from their colour rings. We work closely with the Osprey Study Group and pass all our information on to them in the UK.

Cannon netting

KBO has a team of experienced ringers qualified to catch birds with a cannon net. This equipment allows us to catch terns, gulls and waders in good numbers. Our focus is on Sandwich Terns and we have so far caught 10 birds all of which have been colour ringed. We are working closely with the National Trust colour ringing tern chicks on Blakeney Point. We actively search for colour ringed terns in Kartong and some excellent sightings can be seen on the Recoveries and Controls page. The use of the cannon net helps us to sensitise our work to local people.
