Possibly, not one of our best years for chough breeding at Paradise Park. However, the lack of choughs bred in captivity here has been eclipsed by the success of the new population on Jersey, and the wild birds in Cornwall.
Here at Paradise Park, although we had plenty of eggs, four of our five pairs did not produce chicks. The honours were once again taken by nest number one, which produced three chicks – all of which are males. These have now been moved out into the large 30 metre flight \ socialisation aviary, where the youngsters are getting used to life in a flock. The young birds are now very similar in size and colour to the adults, the main difference being the paler bill and legs. (There is, of course, a difference in behaviour – they tend to follow their parents, begging for food. The parents do their best to ignore them).
The news from Jersey is very encouraging, with the population steadily increasing. This year there were 13 pairs building nests. Most of the nests were close to the release site at Sorel, or in the quarry nearby.
However, one pair did raise a chick away from the release site, and with no interaction at all with any feeding stations. This chick could be regarded as the first truly “wild” chough chick produced so far, with no support from the release program. The parent birds have managed to find feeding sites of their own.
The 13 nests produced 13 chicks in total, with most nests reaching egg or chick stage. More news can be found on the Birds on the Edge website.
There were also two parent-reared choughs produced at Jersey Zoo (Durrell Wildlife Conservation Trust), adding to the potential of the captive breeding program.
The ongoing resurgence of the chough in Cornwall continues. This year there were 12 successful breeding nests, which produced 38 fledged choughs in total.
The resident birds are now spreading around the coast, and can now be seen from The Lizard all the way round the coast as far as Newquay. The location of the nests is still subject to a degree of secrecy. Large groups of choughs can now be spotted regularly in West Cornwall. The current population is now close to 100 birds.
This is excellent news for all involved in the monitoring and conservation work. More news can be found at the Cornish Choughs Twitter feed.
