Ravens

An early breeder, we have ringed Raven nestlings at one site since 2014. To date 21 chicks have been ringed and the average brood size has been three. Nineteen have also been colour-ringed. We've had one recovery so far, a chick from 2014 was found dead in a sheepfield in West Yorkshire, 73 km away.

Cormorant movements

As can be seen from the map below, reproduced from the 2020 report, Cormorant CX4 (5268887 - purple line) is highly mobile, regularly commuting between Merseyside and the south-east coast. It has now been seen again at Havergate Island NR in Suffolk where it seems to like spending the winter.
