Task The grassland at Victoria Tower is managed with an annual late-season cut, with patches of uncut vegetation left for overwintering invertebrates in different parts of the site from year to year. This task will primarily involve raking up and clearing cuttings, although we may also undertake a small amount of sensitive scrub management and self-seeded sycamore control if time allows. We will work with the National Trust for Jersey.
If you have any questions, or if you wish to be added to the Jersey Conservation Volunteers email list, please contact either Julia Clively (tel: 441600; email@example.com) or Jon Parkes (tel: 483193; firstname.lastname@example.org).

Refreshments We will be treated to Kim’s latest batch of delicious cakes, washed down with a nice cup of tea or coffee.
The UK’s wildlife continues to decline according to the State of Nature 2019 report. The latest findings show that since rigorous scientific monitoring began in the 1970s there has been a 13% decline in average abundance across wildlife studied and that the declines continue unabated.
Following the State of Nature reports in 2013 and 2016, leading professionals from more than 70 wildlife organisations have joined with government agencies for the first time, to present the clearest picture to date of the status of our species across land and sea.
The State of Nature 2019 report also reveals that 41% of UK species studied have declined, 26% have increased and 33% shown little change since 1970, while 133 species assessed have already been lost from our shores since 1500.
Butterflies and moths have been particularly hard hit with numbers of butterflies down by 17% and moths down by 25%. The numbers of species, such as the high brown fritillary and grayling, that require more specialised habitats have declined by more than three quarters.
The UK’s mammals also fare badly with greater than 26% of species at risk of disappearing altogether. The wild cat and greater mouse-eared bat are among those species teetering on the edge of disappearing.
Much is known about the causes of decline and about some of the ways in which we could reduce impacts and help struggling species. The evidence from the last 50 years shows that significant and ongoing changes in the way we manage our land for agriculture, and the ongoing effects of climate change are having the biggest impacts on nature.
Pollution is also a major issue. Whilst emissions of many pollutants have been reduced dramatically in recent decades, pollution continues to have a severe impact on the UK’s sensitive habitats and freshwaters, and new pollutant threats are continuing to emerge.
Daniel Hayhow, lead author on the report, said: “We know more about the UK’s wildlife than any other country on the planet, and what it is telling us should make us sit up and listen. We need to respond more urgently across the board if we are to put nature back where it belongs. Governments, conservation groups and individuals must continue to work together to help restore our land and sea for wildlife and people in a way that is both ambitious and inspiring for future generations”
“In this report we have drawn on the best available data on the UK’s biodiversity, produced by partnerships between conservation NGOs, research institutes, UK and national governments, and thousands of dedicated volunteers. It’s through working together that we can help nature recover but the battle must intensify.”
Whilst the data that the report shows are alarming there is also cause for some cautious hope. The report showcases a wide range of exciting conservation initiatives, with partnerships delivering inspiring results for some of the UK’s nature. Species such as bitterns and large blue butterfly have been saved through the concerted efforts of organisations and individuals.
Reflecting growing concern about the environmental and climate emergencies, public support for conservation also continues to grow, with NGO expenditure up by 26% since 2010/11 and time donated by volunteers having increased by 40% since 2000. However, public sector expenditure on biodiversity in the UK, as a proportion of GDP, has fallen by 42% since a peak in 2008/09.
The report has a foreword by a collective of young conservationists who are passionate about conservation and the future of our wildlife and nature to preserve it for future generations.
Dan Rouse, a young conservationist said, “Nature is something that shaped my childhood, that allowed me to be free to use my sense of wonder, and to gain an insight into the wonderful world of nature! It’s young people that are now picking up the baton to save our nature – we’ve already lost Corn Buntings and Nightingales in Wales – how long until they’re gone from the rest of the UK? Along with the eerie calls of curlew and the gentle purr of the turtle doves.”
Sophie Pavelle, a young conservationist said “What a huge wake-up call 2019 has been! I have felt the loss of nature more acutely this year than any other. A dawn chorus less deafening, hedgerows less frantic, bizarre, worrying weather…it seems that in a more complex world nature is tired, muted and confused. People protect what they love, and if we can find quirky, empowering ways to encourage young people to connect with nature emotionally and see it as something they can truly champion – only then can we dig deep to find real hope for a brighter, sustained future for our natural world.”
Locally, partners in the report include Channel Islands representatives (see the list below) and Guernsey’s Andy McCutcheon, Principal Environment Services Officer, Agriculture, Countryside & Land Management Services (ACLMS) “Guernsey welcomes the opportunity to be part of the State of Nature report. The report paints a picture which should concern everyone. We have had a Biodiversity Strategy in place for nearly four years and this report forces us to face facts. It is only by understanding what we are losing and how we are losing it that we can begin to reverse the serious decline in our species rich habitats such as unimproved grassland.”

The biodiversity crisis has come to our backyards. In less than a single human lifetime, 2.9 billion breeding adult birds have been lost from the United States and Canada, including birds in every ecosystem. Numbers have plummeted even among familiar species: the dark-eyed junco has lost an incredible 175 million individuals from its population. The white-throated sparrow has lost 93 million. To put it another way, we’ve lost more than one in every four birds since 1970.
These findings were reported in the world’s leading scientific journal, Science, by researchers at seven institutions, including American Bird Conservancy. Watch the short video highlighting the main findings and the threats behind the numbers above.

There’s no time to lose
Birds are signalling a broader crisis in the natural world — one that is echoed by global losses in insects, amphibians, and other wildlife. The disappearance of even common bird species indicates a shift in our ecosystems’ ability to support basic birdlife.
Of the nearly three billion birds lost, 90% came from just 12 bird families, including (New World) sparrows, (New World) warblers, finches, and swallows. These common, widespread species play influential roles in ecosystems. If they’re in trouble, the wider web of life, including us, is in trouble, too.
Behind the numbers
This is the first study to undertake an accounting of the net population changes across a total of 529 breeding bird species in the United States and Canada. The researchers analysed birds on a group-by-group basis, allowing them to identify declines among species that use similar habitats. The findings included 48 years of data from multiple independent sources, including the North American Breeding Bird Survey and the Christmas Bird Count. A comprehensive analysis of 11 years of data from 143 NEXRAD radar stations showed a similarly steep decline in the magnitude of migration.
Where the losses are
A number as big as 2.9 billion is hard to fathom. Look at it like a balance sheet. Each year, many birds produce young while many others die. But since 1970, on balance, many more birds have died than have survived, resulting in 2.9 billion fewer breeding birds today.
Some ecosystems show worse losses than others. For example, forests alone have lost one billion birds since 1970. Grassland birds are also hard hit, with a 53% reduction in population — more than 720 million birds. Aerial insectivores — birds like swallows, nighthawks and flycatchers — are down by 32%, or 160 million. Coastal shorebirds, already at dangerously low numbers, lost more than one-third of their population.
The volume of spring migration, measured by radar in the night skies, has dropped by 14% in just the past decade.
Drivers of decline
Although the study did not investigate causes, scientists have identified that habitat loss is the biggest overall driver of bird declines. Habitat loss occurs when land is converted for agriculture, development, resource extraction, and other uses. Habitat degradation is a second cause of losses. In this case, habitat doesn’t disappear outright but becomes less able to support birds, such as when habitat is fragmented, altered by invasive plants, or when water quality is compromised.
Aside from habitat loss and degradation, other major human-caused threats to birds come from cats and other invasive species; collisions with glass and industrial infrastructure such as communications towers and wind turbines; and exposure to pesticides and other toxics.
Climate change is expected to exacerbate these threats, as well as creating new challenges; for example, changing habitat distributions and shifting the timing of peak food supplies for birds.
Fortunately, individuals can take action to reduce many of these threats. Learn more about ways you can help birds through everyday actions.
Help combat the crisis
ABC’s “50-50-5” plan in North America is designed to address the current bird crisis there. It will make a transformational difference for birds, and at the same time, protect millions of additional species of plants and animals, and make a huge contribution to solving our planet’s biodiversity and climate crises.
The plan is to save 50 flagship bird species, protect and conserve 50 million acres, and fight five critical threats. Can we do the same in Europe?

Belle-Île, nine miles (15km) off the coast of the Gulf of Morbihan, is Brittany’s largest island and a popular place for visitors. Birds On The Edge correspondent Regis Perdriat took his family over to this beautiful island (pun fully intended) in May but wasn’t content with just relaxing on the island’s many beaches. Belle-Île has red-billed choughs.
At 32 miles² (84 kilometres²), Belle-Île is smaller than Jersey (45.6 miles²) and, with a truly rugged coastline, it has far fewer residents, only 4,920 in the 2009 census. This human population may increase to a whopping 35,000 in summer – Jersey has nearly 107,000 residents. Anyway, plenty of nice chough-friendly coastline and although an important site for Brittany’s choughs there may sadly not be many these days. Maybe there are only around 20 birds; however, as Regis was able to confirm, they are breeding.
August has been a relatively quiet month. The youngsters are showing increasing signs of independence and the flock is spending more time exploring the island.

The results are in
Results came back from the UK lab regarding the DNA sexing samples. From the twelve we sent off, three are male and five are female. And one was Chewbacca (see below). We need to re-sample three birds due to a mix up in the lab and we still have the Plémont chick to catch.
DNA sexing results have shown ‘PB-CS‘ is one of at least five females hatched this year. Photo by Liz Corry.
There is growing concern for four birds as they have not been seen in a long time. We receive reports from Plémont of 2, 3, 5 birds, but it doesn’t necessarily mean Earl, Xaviour, or their chick are present in that group.
Chough travels around the north coast
On the occasions when I have been able to go on a ‘chough hunt’ around Jersey, I fail to see the missing chicks. In fact, quite often I fail to see any choughs!
I did watch Earl and Xaviour at Plémont one evening. Lovely to see them foraging around the cliffs; Earl looked to have been bathing in the intertidal zone. No sign of a third chough on that occasion.

Over at Les Landes, the only choughs I have seen there this month were Beanie Baby and Beaker. A surprise pairing and a delight to see. They kept me on my toes, literally, as I only heard them after completing a lap of the racecourse. They were over by the MP3 tower foraging on the cliffs above a group of rock climbers. As I reached the cliffs they decided to fly over to….the racecourse, so back I went. They waited for me to arrive, perched on the railings so I could see their leg rings, then flew mockingly over to Le Pinacle.

Anyone who knows the area is fully aware of how the footpaths are interwoven into the heather and gorse landscape. The only straight lines belong to the model aircraft runway to the south. Cue WW2 fighter planes ducking and diving overhead as I navigate over to Le Pinacle, a Neolithic site with the ruins of an old temple (200 AD), to find two choughs perched on top of the granite stack.

For the visitor, it is breathtaking scenery. For the chough monitor, it is breath-holding for this area is synonymous with peregrines. The choughs were risking life and limb. I didn’t have to hold my breath for long as they moved on again. This time I lost them as they followed the cliff face obscured from my view.

Of course, just because I have not seen them doesn’t mean the choughs are not around. A tourist spotted two choughs at Les Landes and emailed the few photos she managed to snap before they flew away (bird not tourist). Squinting at the leg rings I think she saw Beaker and guessing the second was Beanie Baby!

We have also had three confirmed sightings from Le Pulec this month. None when I visited of course. The same for Grosnez and at Grantez.

All of the sightings away from Sorel are of pairs or small groups in the single figures. We are only seeing numbers in the 20s or 30s at the supplemental feeds compared to the 30s or 40s last month. This is because the pairs no longer need to find food for their chicks as well as themselves. The independence is allowing them to spend more time away from Sorel which makes it harder for us to monitor.
It is now hard to spot the juveniles in the flock unless you can read their leg rings. Photo by Liz Corry.
Of course they could just be sulking over the fact we have not been able to provide as many live mealworms this month. The UK supplier has had a few problems and a change in delivery policy to the Island has resulted in delays. Delays for live food tend to result in death; the correct temperatures are not maintained and the insects don’t get fresh air. We have had to send most of our monthly order straight to the compost bin.
I will end August’s report as it started with the sexing results. The chicks were not the only ones to be tested. We sent a sample from Chewbacca, a two-year-old, parent-reared bird.
The lab came back with female whereas the first test back in 2017 said male. Judging by size and behaviour this Chewbacca is definitely a girl.
