Chough report: March 2020

Welcome to Trinity Parish

Trinity residents, be on the lookout for unidentified flying black objects with red bills!

Honeydew, a 2-year old wild Jersey chough, popped by the Zoo on 23rd March. Perched on top of the chough enclosure, she peered down on the residents inside, had a quick preen, a good natter, then left.

Piecing together reports from Zoo staff, she was first spotted shortly before 8 am. Apparently perched outside a student’s bedroom window along Rue des Bouillons near the Zoo.

Note for future applicants – we have not trained the choughs to be your morning wake-up call.

Honeydew then paid a visit to our Finance Team (claiming expenses?). Their office is directly next to the chough aviary in the Zoo, prompting immediate panic that one of the birds had escaped.

This was to be the first of many visits to the Zoo throughout March. It wasn’t possible to identify the individual chough on each visit. Honeydew was identified once. Bee, another 2-year old wild female, was seen twice. One report cited nesting material being carried by a chough flying around the La Fosse end of the site. Could they be nest building in the parish?

Speculation intensified with confirmed sightings of a pair around Les Platons and Egypte. Having walked the dogs there on many occasions, I know that this section of coastline has great potential to support a breeding chough pair. Just imagine how many choughs Trinity could support with effective bracken management!

Latest edition to the chough team

Last summer, Diva Opera raised funds for Durrell yet again through their annual opera festival at Domaine-des-Vaux, Jersey. We were very grateful to hear that the money raised in 2019 was to be split between the chough project, to purchase a vehicle, and the Durrell Academy scholarship programme.

With funding secured, I approached several dealers on the Island to ask the impossible…can you supply a high clearance, 4WD, electric or hybrid vehicle with plenty of boot space for a third of the price you would expect to pay?

Unsurprisingly the answer was no.

Not to be defeated, Falles Motors and their Bagot Road dealership came up with the next best thing! Please welcome Diva the Dacia Duster. Rather aptly, she makes a lot of different noises thanks to her intelligent features.

She isn’t electric or hybrid, but we did select the most eco-friendly option from the range. Plus I can now leave my car at home and cycle to the office since it won’t be required.

Steve Rolland and Phil Valois at Bagot Road provided great service and support throughout. Even to the point of giving us a heads-up that the dealership may go into lockdown so collect the vehicle NOW!  Diva was put to immediate use and has already made several trips to the aviary to top-up the water tanks.

Having our own project vehicle will hopefully solve our lack of student placement uptake. Many students wishing to apply don’t own a vehicle. If they do, the costs incurred in bringing one over are often too great. Bicycles are all well and good until you need to take 20litres of water to Sorel.

Out with the old, in with the new

We replaced the free-standing roost box in the aviary with a brand spanking new one. For the few birds still sleeping at the aviary they need a sturdy, sheltered space to nap in. After seven years, the box we had was in a sorry state.

Mike from the Zoo’s Site Services team cut the wood, numbered all the parts, built it, then immediately dismantled it. Yes, he found this strange too! I had asked him to build it flat-pack to transport along the footpath (no Diva at that point).

I was joined at Sorel by two very good friends (and project partner) who helped me reassemble and hoist it into place. At this point in the pandemic, we were maintaining a social distance of 2 metres. We went into complete lockdown not long afterwards.

Fifty shades of grey

I received an emergency call from Ronez Quarry on 25th March. Staff had spotted a chough on the ground, wet and covered in rock dust. The mix of water and ‘dust’ created a consistency almost like wet cement clogging all the flight feathers. Staff scooped her up so I could take her to the Durrell vet on duty. From the leg rings I knew it was Pyrrho a female nesting in the quarry.

Although lockdown had not kicked-in at this stage, Jersey Zoo had taken precautionary measures against COVID-19. The Vet Department was off-limits to keeping staff. Equipped with mask and gloves, I had to put Pyrrho down on the ground (in a box), step back, and let Andrew pick her up and disappear inside.

Several hours later he emerged. A broken man. A broken, yet victorious man. Andrew had a lot of cleaning to do of both bird and, in the aftermath, building.

Pleased to say, Pyrrho had no injuries other than a loss of dignity. I was able to release her back at Sorel once she had dried-out and had a chance to eat. She flew straight back towards the quarry. Hopefully she can avoid getting in that state again.

Sign of the times – nesting season

Several birds have been busy collecting wool to line nests. Notably Kevin, Lee, and Minty in the second week of March. Lots of ‘peacocking’ by the males and a couple of copulation events witnessed.

We finally had our first evidence of Jersey choughs using horse hair as lining material. Mainland choughs are known to use this and we provide it to the captive pairs. We have just never seen our choughs use it before despite the abundance of stables in the northern parishes.

Of the twelve males in the Jersey population, ten are paired up and show signs of wanting to nest this year. The other two, Minty and Mac, are only 10 months old and yet to be in a confirmed pair. So where was Minty  taking the wool?!

Love Island

Relationships blossoming this month are that of Vicq and Minty and Honeydew and Baie. The latter are both female. Don’t expect any chicks from that pairing. Nevertheless, their friendship means they can look out for each other if they run into the neighbourhood ruffians. They can also get those hard to reach spots when allo-preening.

Vicq and Minty on the other hand are the pair to vote for. Vicq was a newbie to nest-building last year. Osbourne, her partner at the time, is now missing presumed dead. Step forward Minty one of the two males from the 2019 wild-hatched cohort. With an older female to show him the way we could be hearing the pitter patter of tiny chough feet this summer.

We will do our best to follow all their progress over the coming months. Covid restrictions are likely to reduce our chances of that.

Plémont

Plémont is home to our first successful chough family to breed away from the release site. Their ‘celebrity status’ hasn’t lasted long. Neither father nor fledgling have been seen for several months. Presumably dispersing to that great habitat in the sky. Or emigrating to Sark!? (We still haven’t confirmed the report from last Autumn).

Beaker and Beanie baby, who had been scouting out the area, moved in with Xaviour. Very modern. As the breeding season kicked in the trio stopped visiting Sorel for supplemental food. Beaker and one other chough were spotted feeding at Plémont on 7th March. A roost check confirmed choughs were still using the site.

The only sighting of them at Sorel for the month of March was on the 23rd. Slightly more concerned over Xaviour’s absence if she is playing third wheel to the couple. Hopefully just tied up nest-building and egg-laying. It is a very important job after all.

Zoo news

With the various upheavals in the Bird Department brought on by COVID provision we left it a bit late in setting up the breeding pair in the Zoo. Tristan and Penny were still housed with their two girls now 10 months old. At the end of March keepers managed to catch up one of the youngsters and move her to an off-show aviary. The second juvenile cooperated a few days later. By then it was April so you will have to read the next report to find out what happened next.
