Channel Islands bird list updated

Posted on by

Working list of Channel Islands birds to December 2022

Each year we update the list of all the bird species recorded in the (British) Channel Islands of Jersey (including Les Écréhous and Les Minquiers), Guernsey (including Herm, Jethou and Lihou), Alderney (including Burhou and the Casquets) and Sark (including Brecqhou) that have been
accepted by the islands’ respective ornithological committees. We get reminded of what we’ve seen and what we missed. We see what changes are happening in our bird fauna and, of course, we might think, only very briefly of course, on which island has seen the most. 

2022 saw the islands’ first bridled tern, in Jersey, and Blyth’s pipit in Guernsey. Alderney continue to build their Island list up with firsts of Caspian gull, western Bonelli’s warbler and Eurasian treecreeper. Sark saw their first fan-tailed warbler, a species that has bred sporadically across the other islands since the first in 2001. Jersey recorded the islands’ first Iberian wagtail, a distinctive race of the yellow wagtail, the fifth race of this beautiful bird to be recorded across the islands. 

With many of our bird populations in decline it is good to report successes. Roseate tern and European nightjar bred again in Jersey and great spotted woodpecker bred for the second consecutive year in Sark. Cirl bunting records are increasing in Guernsey and Alderney and, with our seabird populations looking so fragile, it is exciting to see that common guillemot is thriving in Sark. 

Some birds we know but can still be surprised by. The first glossy ibis in the islands was likely recorded in Jersey in 2007 (there is a report of one shot on Sark in 1909) but, with a flock of 10 in Guernsey in 2017, the wintering flock of 13 in Jersey in 2022 looks like a sign of things to come. This long-legged waterbird joins that list of other elegant wetland species increasing in numbers across the islands that includes egrets, herons, spoonbills and black-winged stilts. 

Another surprise in 2022 came further out to sea. Jersey had one record of great shearwater, in 1995, with others recorded occasionally from Guernsey and Alderney. “Sizeable flocks” were reported from Guernsey in July 1950 but the 400+ birds seen from Jersey in September and October 2022 was a shock. Will this species be seen, like Balearic shearwater, more often in our waters? 

No summary is complete without noting Alderney’s further visiting great bustard. The bird that visited in May was their fifth visitor from the UK since 2014 (see the Great Bustard Group). Mind you, two of Jersey’s red-billed choughs paid visits to Guernsey and Sark last year. And went home!

And the island totals? Jersey have recorded 341 species, Guernsey 333, Alderney 312 and Sark 226. See and download the full list here. 

 

 

Chough report – May 2023

Brand new hatches

The chough team have been racing against the (breeding) season, trying to repair the aviary. The large holes that were in the tops of the aviary’s netting are now fixed; there are only a few little holes left to sew up. In the meantime, the team has been preparing and replacing the release hatches on the front of the aviary. The aviary itself is always left with two release hatches open, so that the visiting choughs can be identified more quickly and with more ease as they fly in than if 43 choughs flew through all four entry points at the same time! The hatches are also an essential for the team to capture the choughs inside if they need to be health-checked or ringed. As the breeding season was well underway, the team needed to ensure that the front release hatches were fully functional. This would ensure that when the ‘choughlets’ had fledged, left their nests and eventually showed up at the aviary, they could be caught and receive their identifying rings. This is, however, if the choughs don’t outsmart the team – which they can do, very often!

Are there chicks among us?

Over the course of early May, it became clear that the pairs’ females had been sitting tight, incubating in their nests. This became obvious to the keepers by the lack of female presence from the known breeding pairs with only the males turning up for food, typically filling up and quickly flying off. To the end of May, we began to notice the females starting to visit the aviary again. Many of the females were wing-begging at the keepers while awaiting the feed. This, combined with the breeding pairs arriving at the aviary in staggered intervals, suggests to us that chicks had hatched and, therefore, the pairs were co-parenting again, each retrieving enough food to feed themselves as well as their hungry chicks at the nest.

Ronez Quarry visit

The team visited Ronez Quarry to renew their health and safety permission with the site and for our new chough student, Grace, to experience the grand tour of the quarry. While visiting, we had the opportunity to see how some of the chough pairs were getting on at their nests. Red & Dingle had built a very nice nest in their usual spot, but unfortunately, much like last year, they had not laid any eggs, but we remain hopeful that they will do later. Dusty & Chickay looked as though they had at least one chick in their nest this year while Bo & Flieur had two if not three little beaks shouting for food in their nest. Kevin & Wally had three chicks in their nest. Four other nests were occupied by Trevor & Noirmont, Lee & Caûvette, Percy & Icho and Green & Pyrrho: these nests were inaccessible without specialized equipment – but there were plenty of chick-related noises and pair visitations that would suggest that these other nests were very active as well!

Plémont pair update

Minty & Rey had a lot of obstacles to overcome this breeding season; they built a nest in a new location at a local stables, but the nest and the choughs were deterred from the area. The team had been monitoring their usual nesting spot in Plémont in the hope that they would return and produce some wild ‘choughlets’. The pair had both been seen visiting the nest, but we didn’t know if they had already laid in their previous nest. While visiting Plémont, it was clear that Rey was incubating on the nest as she flew out on Minty’s arrival to be fed by him on the cliffs above the nest. At the very end of the month, we celebrated the sounds of tiny chick noises and the pair both returning to the nest to feed their chick(s). The chicks were not visible, and we assumed they were only a few days old.
