2019 July Breeding Report & Round-up

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.

Paradise Park
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).

Jersey
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.

Cornwall
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.

Chough watching trip to Jersey

We (Ali and myself, plus sister Elaine), were a bit late with our Jersey migration this year – but have just returned from a splendid few days catching up with the choughs, sheep, and release team on the island.

The six birds sent from Paradise Park had just completed their quarantine, and were eager to get out on the cliffs with the rest of the flock. They were released on Monday 3rd October – we got there on the evening of the 4th.

We were very lucky with the weather, and although we stayed dry, the wind was showing signs of impending winter. We soon got to the cliffs and met up with Liz Corry and team – and, of course, the choughs. The birds are being closely monitored, and all the newly released ones have been fitted with radio transmitters. The aerials could be seen through binoculars and it was clear that all the birds were mixing together well.

The chough is renowned for its incredible flying ability, and the Jersey flock is no exception. The older birds have truly mastered their environment, and the youngsters are picking up the same skills at a phenomenal rate – in fact the new and established birds could only be told apart by their transmitters (or lack of). The birds like nothing more than to dance on the updrafts, and ride the thermals. “Like black handkerchiefs blown by the wind” as Elaine said.

 

The flock of birds can relocate themselves remarkably quickly – one moment they are all feeding close to the aviary – and the next they are several hundred feet up in the air…

We didn’t actually get to see all thirty-five choughs at the same time, although we are sure we encountered them all during our stay. We found out that the “teenagers” (as Liz calls the year-old birds) have decided to go exploring – much the same as last year.

They have been seen several kilometres away on Jersey’s racecourse on the north-west tip of the island. They may be scouting for possible nest sites, or they may have found a new food supply. (There is a small herd of cows in a field in the centre of the course – ideal for trampled grass and cow-pats).

The Bracken Bashers

One of the aims of the Birds on the Edge project is to restore the coastal habitat around the island of Jersey, and as such they use a variety of methods. These include volunteer teams cutting gorse down, and bashing down encroaching bracken with tractors.

There is another dedicated team who are out in all weathers doing their bit for conservation. These are the Manx Loaghtan sheep (Manx Longhorns), and they are doing an impressive job. They have increased their flock even quicker than the choughs, there are now in the region of 200 sheep.

I was lucky enough to have a close encounter with one of the ladies on the cliffs while chough watching – it’s almost like she’s guarding them.

Keep up the good work Sharon – and everyone else!

The usual thorough monthly report from the Birds on the Edge team for September is here.

Six choughs ready for their longest flight so far

Six More to Jersey

Six young choughs bred at Paradise Park this year have gone to Jersey to be released.

Lee Durrell and Colin Stevenson collected them by plane on August 31st, arriving at Perranporth airfield, near Truro, as they have done in previous years. Lee and Colin were accompanied by Durrell staff Bea Detnon and Jessica Maxwell.

Going by plane saves many hours travelling by ferry, and we are very grateful for Lee and Colin’s help with this. The flight takes just over an hour and means the young choughs will be in the release aviary by the afternoon, after veterinary checks.

Chough Re-introduction Field Manager at the Durrell Wildlife Conservation Trust, Liz Corry, was waiting for the birds to arrive. She has planned for the arrival in advance.

The six choughs bred at Durrell Wildlife Park were released a few weeks ago. These birds are to be mentors for the new arrivals. They have been lured back into the release aviary and the Paradise Park birds will join them.

After a short period of quarantine, the whole group of twelve will be let out together to mix with the larger flock. The six local birds will share invaluable knowledge with the new birds, improving their chances of survival.

It is incredibly gratifying to see at first hand the young birds we have raised heading off to be released. Just four months ago we were feeding and weighing these youngsters, and now they are off to Big School…

Birds on the Edge Summer Update

It’s been a busy couple of months here at Paradise Park – however over on Jersey things have been even more hectic.

July Headlines

July saw four chicks being fostered by the “Italian” chough Gianna, before being moved to the release aviary for training and orientation. They were joined by two parent-reared chicks, giving a total of six young birds to join the wild flock.

The wild birds were also producing chicks. Three nests were successfully built, and four wild chicks fledged in all. Last years’ wild male chough Dusty showed signs of maturing early, and was seen making amorous advances.

August Headlines

All the new arrivals were given time to acclimatise to their surroundings, and their new flock-mates.The youngsters were given some training to respond to the supplementary feeding signals. In August, they were good to go.

The new birds quickly adapted, and are now part of the flock. So far, all are doing well, and have been seen taking lots of prey items from larvae to butterflies.

The official launch was back in 1987 – not a good time for chough-lovers as the species had died out in Cornwall. But things were about to change…

The natural recolonisation by three birds in 2001 gave us great opportunities to observe the behaviour of wild birds right on our doorstep.

In the 1980s we had had some success in breeding choughs here at Paradise Park, but it was just one or two chicks a year, as we learned what they needed. Now we have become somewhat expert and our captive pairs produce around ten chicks each year.

This has enabled us to fulfil our objective on Jersey and with the help of our hard-working partners at the Durrell Wildlife Conservation Trust, thirty – yes THIRTY – choughs are now living free on the island after an absence of 100 years. The method used for the Jersey release is a template for further re-establishment to help join up the scattered populations and spread genetic diversity.

I am off on holiday to watch the start of Le Tour at Mont St Michel. The overnight ferry passes Jersey, so if I’m very lucky I might just see some black specks in the distance…

 

Frosty morning for the released birds.

Birds on the Edge January Update

The new year brings stormy weather and winter frosts, making life tougher for the Jersey choughs.

The choughs are now foraging in different locations, possibly due to less insects being available in their regular haunts.

The report features some more video footage showing the birds feeding in the release aviary. There is also footage of the birds enjoying a clear winter sky, with males showing a keen interest in the females in the group.

So far all the released choughs have done well over the winter months, and survival rates have exceeded expectations. However, the report does end with the news that Blue has gone missing. Blue is one of the first wild choughs to breed on Jersey – raising her son Dusty last summer.

The winter weather is now setting in, causing more difficulties for the monitoring team than for the choughs themselves.

There are some great videos, showing how the birds cope with the changing weather conditions – some even decide to find shelter “indoors”.
