The Pen Llŷn & Iveragh Chough Count

By Fiach Byrne

Jersey Island’s striking landscape shares many similarities with the Llŷn Peninsula in northwest Wales and the Iveragh Peninsula in southwest Ireland. Each of these regions are popular tourist destinations that are heavily influenced by agriculture and their connection to the sea. Their coastal landscapes are also extremely important to many forms of wildlife, not least our favourite corvid, the red-billed chough. The choughs’ iconic call, coupled with their bright red beaks and legs are a staple of the Llŷn and Iveragh Peninsulas. And these birds are clearly held in high regard on Jersey since their reintroduction in 2013.

On the Llŷn and Iveragh Peninsulas, choughs nest within mines, quarries, farm buildings and along cliff faces. A short distance from these nest sites, choughs have access to a mix of foraging habitats such as beach, sand dune, earth banks, coastal and agricultural grasslands, coastal heath and some well-grazed upland sites. Here, choughs can find their favourite food items such as beetles, ants and spiders, as well as the larvae of beetles, butterflies and moths. The importance of Llŷn and Iveragh for choughs is one of the primary reasons why ‘Special Protection Areas’ (SPAs) have been designated on both peninsulas.

The most recent national chough censuses indicated that chough populations across the UK and Ireland are relatively stable, although there were some concerning declines in certain regions. These national surveys are usually conducted every ten years in the UK. However, there was nearly two decades of a gap between Ireland’s 2002/03 national chough census and the most recent census carried out in 2021. Although these censuses provide invaluable insights into the health of national and regional chough populations, more frequent updates would help us determine how our choughs are faring in the years between censuses.With this in mind, the University College Cork-led LIVE Project, in collaboration with the National Trust in Wales and the Royal Society for the Protection of Birds (RSPB) organised a cross-border ‘Chough Count’ on the Iveragh Peninsula in southwest Ireland and the Llŷn Peninsula in northwest Wales on 12th March 2022. This initiative typifies one of LIVE’s main objectives – the sharing of knowledge and best practice between our two peninsulas.

The Llŷn Peninsula’s second ‘Chough Count’ saw 51 volunteers record 254 choughs as the sun shone in north Wales. Iveragh’s inaugural count saw twenty-six volunteers record 64 choughs in quite challenging weather conditions. By conducting annual counts of Llŷn & Iveragh’s choughs, we can detect trends in these populations in the years between censuses and we can identify important habitats for this protected species. The 2022 chough count also gave our surveyors the opportunity to record some of our other native birds such as skylarks, fulmars, white-tailed sea eagles and a hen harrier in Iveragh, as well as red kites, peregrine falcons and a green woodpecker on Pen Llŷn.

Distribution of records during Pen Llŷn’s second ‘Chough Count’ held on 12th March 2022.

The LIVE Project (ecomuseumlive.eu) has received funding from the European Regional Development Fund through its Ireland Wales cooperation programme. Led by the School of Biological, Earth and Environmental Sciences in University College Cork, LIVE works to enable the coastal communities of Llŷn and Iveragh to promote their natural and cultural assets, with the aim of encouraging more sustainable tourism opportunities in these rural regions of Ireland and Wales.

Chough report: October 2021

Report by Liz Corry

Out of sight but not out of mind

A year ago we had our first-ever confirmed sighting of a chough off-island when a juvenile flew over France. Has it happened again?! 

Rocky, a juvenile male from Ronez Quarry, is missing from the flock. He has bright pink and yellow leg rings making it theoretically easy for the team to pick him out in a crowd.  He has not been at the supplemental feed. That alone doesn’t mean much these days; however, on one occasion he was the only one not to turn up. This suggests he is either dead or has left the Island effectively reducing the population to 31 choughs.

It would be good if we can start raising our profile across the Channel Islands, Brittany, and Normandy to enable the public to report chough sightings if indeed the birds have flown further afield.

Rocky is not the only one to leave Sorel. Aaron spent a busy weekend transporting sheep off-site to another location for livestock management reasons. I’ve no one to talk to now when I’m cleaning the aviary!

Storm damage

The sheep were still out at Sorel when the storms hit this month. We had a couple of weeks where we were strongly reminded that winter is approaching.

The gales managed to break a food stand, break signposts, dislodge a water butt (it was empty to be fair), and pop several rivets. All easily fixed and looking like new. Or, in the case of signage, actually new thanks to the Government Countryside Rangers.

A few small tears have appeared in the netting and fixing points in need of attention. This will require some extra hands and a sturdy ladder.

The sudden downpours turned walking to the aviary into a game of will I or won’t I end up like a drowned rat? Should I leave the dishes out or condense them down to put under cover? The latter confusing the choughs for a split second when they didn’t find a food dish where it normally would be.

New nest boxes for 2022

We have built two new nest boxes with a grant from the Jersey Ecology Trust Fund. These will replace two existing nest boxes which need to come out for different reasons. Percy and Icho’s box currently requires the hiring of a cherry picker to ring their chicks. The new nest design will allow access from inside the building. Plus, the current one became lopsided back in 2019 and is increasingly at risk of falling down. Not ideal for quarry staff least of all the choughs.

Ronez Quarry will be installing the boxes before Christmas ready for the next breeding season.

The grant provided by the Jersey Ecology Trust Fund included several other items such as DNA sexing kits and leg rings. For various reasons, we came in under budget. The Trustees kindly permitted us to use the remainder of the budget to purchase new binoculars. For which I am very grateful – I was beginning to think it was just my eyesight!

Celtic cousins 

Regular readers might remember that the new design of nest box came from the owners of a renovated barn in Ireland. In fact, it was the October 2019 report where we featured the same nest box needs (thanks a lot COVID-19!).

Ireland is home to a population of almost 850 breeding pairs. This is more than Cornwall, Wales, Scotland, and Jersey’s numbers combined. Yet this still makes it a scarce species in Ireland restricted to the western Atlantic coastline.

One conservation initiative involved with Irish choughs is LIVE (Llŷn Iveragh Eco-museums). The overall aim of LIVE  is to enable coastal communities to promote their natural and cultural assets, creating opportunities for sustainable tourism, especially outside of the traditional peak tourist seasons. LIVE uses the Ecomuseum model of co-operative marketing to create a powerful suite of digital and non-digital resources for eco and educational tourism. These resources are underpinned by knowledge of the local environments of the Llŷn Peninsula in Gwynedd and the Iveragh Peninsula in Kerry.

As part of this, Fiach Byrne, University College Cork, has has been investigating winter habitat use of choughs around the Iveragh peninsula, County Kerry. He recently presented his findings online; the YouTube video is below.

To find out more got to www.ecomuseumlive.eu or follow them on social media (@ecomuseumslive).

We hope to be hearing more from Fiach and the LIVE team in the future. There are lessons we can learn from our Celtic cousins to help the Jersey choughs thrive.

And finally…

Reviewing camera-trap footage can often be monotonous especially when it is just a blade of grass that sets off the trigger. Occasionally you come across a real gem. This month we managed to capture a series of images showing the barn owl hunting at the aviary.
