Chough report: July 2019

The choughlets finally made it across to Sorel this month to join the flock at the supplemental feed. Some are flying further afield following their parents to the west coast.  They now face the same challenges life throws at all choughs; finding food, avoiding predators, and putting up with those pesky folk who keep wanting to put leg rings on them.

With nest sites vacated for another year, the adults are spending more time together at Sorel. The addition of hungry mouths to feed has seen attendance records at the supplemental feeds increase. It has allowed us to get a better understanding of total population size. More on that later.

This year sixteen choughs fledged from various nest sites at Sorel and Plémont. Sadly, as reported last month, three died within a week of fledging all injury related. That still leaves thirteen hungry mouths to feed.

It has been quieter this year at Sorel compared to 2018. The broods fledged at different times. Families were arriving at Sorel days, sometimes weeks, apart giving the youngsters time to adjust. Last year they all fledged within a relatively close time frame. I guess it was noisy because the chicks had to compete with each other for attention.

The surprising news came from Skywalker and Pyrrho who casually rocked up to the supplemental feed one afternoon with two chicks in tow. Quarry staff thought this nest had failed. As first time parents, we had also written off the clutch. Wrong! One of the few times you are happy to be proven wrong.

Earl of Plémont  returns triumphant

Rather a grand title yet justified for the next snippet of news. Earl and Xaviour are returning to Sorel for supplemental food. And so is their chick! On 4th July I found 40 choughs waiting for me near the aviary. As I started going through the roll call, I stared down to find two familiar faces (well leg ring combos) staring back.

I had to work my way through the flock to finally discover which, if any, was their chick. It was positioned at the back of the group, silently getting on with life, foraging for food.

We expected the family to make an appearance at some point; the hot dry summer has hardened off the soil making it impossible to extract insects. Their reliance on the supplemental feed naturally increases at this time. We have also learnt that the cows grazing at Les Landes, a chough favourite, have been removed due to the farmer having to make cut backs. These provided another source of food for the birds especially Earl and his family at neighbouring Plémont. 

Falling foul-can

Work with me on this pun as I’m trying to make light of a tragedy. One of Jerseys licensed ringers, Ian Buxton, contacted me this month with regards to a specimen submitted to the Société Jersiaise. Somebody found the remains of a bird whilst out on the cliffs around Sorel Point. On seeing an address stamped on the metal leg ring they thoughtfully bagged the remains and took them to the museum.

This is how Ian became involved and then sent me the following image…

The legs belong(ed) to one of this year’s chicks – PP036 also known as ‘White over Cerise’.

We do like to wind up our vets at Durrell, but I wasn’t about to submit this for a post-mortem. It is quite likely that the youngster fell foul to the resident peregrine falcon.

PP036 had been absent from the feeds since 13th July and discovered on the 17th. We have three more youngsters on our watchlist who haven’t been seen in awhile. They could simply be with their parents over at Les Landes or Crabbé. Although the recovered legs makes me suspicious.

I have contacted the Jersey Climbing Club to ask members to keep an eye out whilst dangling from granite. They are more likely to come across remains than we are.

Big catch up

To ensure each chough has a unique ring combination we had to plan several catches this month. As well as some unplanned, carpe diem moments. Four broods remained unringed and several adults had lost one or more plastic ring.

The parents of the unringed chicks were understandably protective. They were on the alert whenever we called the group over for food in the aviary. Often they would land on top of the netting and just stare at us until we gave in and left. If they did go inside, they would immediately fly out as soon as one of us merely thought about closing the hatches! 

The added complication was trying to time it when enough staff were available to help out. We only needed certain individuals from a group of potentially 48 birds. Trying to hand net and process that many in a confined space is stressful to the birds. You want to be able to minimise time spent inside.

On the odd occasion the youngsters were helpful. I would arrive to find one or two chicks already inside. In their naivety and panic, they would forget how to fly out of the hatches giving me enough time to reach the handles and close them.

 

The big catch-up came on 19th July when I managed to lock in 34 choughs. Three escaped the hatches in an Indiana Jones style – one of which was an unringed chick. We’ll gloss over that. With the help of a volunteer and a licensed ringer, I hand-netted 28 of the birds, we weighed them, and fitted or replaced leg rings as necessary. All birds were released back into the wild once we had processed them. 

Whilst in the hand, we discovered one of this year’s youngsters had a clump of matted feathers around the neck. It was dried blood. There was no obvious wound, no fresh bleeding, but clearly something had happened since it’s first catch up three weeks ago. One to keep an eye on.

In Memoriam

The big catch up and recent numbers at the feeds are evidence to suggest we have lost eleven choughs since January of this year. This is not including the deceased fledged chicks.

We know the reason for one bird was aspergillosis because we had a body to post-mortem. Around two thirds of the lost birds were in pairs. Their partners have re-paired with a younger male or female. Was that before or after the disappearance? Cue the EastEnders theme tune.

Bracken bashing for charity

Whilst the sheep do a grand job of grazing the National Trust land at Le Don Paton they have their limits. They don’t actually eat the bracken, certainly not in any quantities to make a difference. At least once a year the rangers take a tractor up to clear certain areas. Understandably, the slopes of Mourier Valley aren’t practical even for the most skilled of drivers.

The wonderful staff at HSBC rose to the challenge and volunteered their time to bash some bracken. Despite July’s scorching temperatures the team joined the National Trust’s rangers and did a great job and clearing the vegetation.

The sheep can now take over and make sure it stays low. This is how it would have been centuries ago when farmers kept livestock around the coast. Although I assume with less corporate branding. HSBC also helped the rangers at woodland on Mont Fallu and clearing the alien invasive succulent, purple dew plant, from the salt marsh habitat of St Ouen’s Bay coastal strip.

    “In terms of Celtic, I thought they were flawless today. I mentioned some of the stats throughout the game. It’s ridiculous that any side puts this together. “It was quite incredible.

    Until a few years ago 7 Card Stud poker was the most popular poker game in the world. That, of course, all changed in 2003 when Chris Moneymaker won the World Series of Poker Main Event. Because then, the worldwide Texas Hold’em boom began and it’s now the game of choice for most casual poker players. However, there’s still a very committed group who prefer to play 7-card stud poker both live and online. Considered a “purer” game by traditionalists, seven card stud poker does have one big advantage over Hold’em for rookies: It’s easier to see what kind of hand your opponent has or is drawing to. Click below for more information and our ‘how to play’ guide about each of the casino games we offer. The game begins when a player makes their ante wager and receives two cards. The dealer deals three face-down community cards as well. The goal here is to end up with at least a pair of 6’s. If a player has a pair of 6’s through 10’s, they can push and return all bets. If they have a pair of Jacks (or higher), that’s when they can start receiving payouts.
