After a successful 2016, with a fantastic number of pairs and fledging chicks, 2017 has been ‘challenging’ for the Cornish choughs. An unfortunate combination of some breeding adults lost, young inexperienced pairs and predation, has meant the number of breeding chicks and fledging pairs have been lower than hoped. We have also seen low productivity due to a cool spring when eggs are laid and needing to be kept warm and a very dry period, affecting access to their food supplies.
Choughs also known as ‘digger’ birds, use their long red bills to dig in the ground for invertebrates but would struggle in hard dry ground to do this. Their next source of food would be via the invertebrates found amongst cow pats which proves how important in these times of climate uncertainty, grazing cattle on the coastal fringes is vital for choughs.
Six pairs were successful and most nests have fledged now. 14 chicks in total is still a pretty amazing result, although everyone involved in supporting chough conservation in Cornwall is aware that the population is not at a sustainable level yet and there is work to do to keep them safe and secure. We estimate that there are approximately 30 adult birds currently across Cornwall.
Volunteers from RSPB and National Trust have spent hundreds of hours protecting and monitoring nests, those lucky to see the young fledging have been rewarded by glimpses of parents feeding their chicks and first tentative flights.
This is a great time to see good numbers of choughs in the skies as the family groups are now flocking together and are venturing further as they explore the Cornish coast.
