Success at Plémont!
For a second year in a row the chough pair at Plémont have successfully hatched three chicks. We discovered the happy news at the end of the month. Using a very, very, very, long lens we were able to get photos of the chicks’ heads whilst begging for food.
It is hard to give a precise age without seeing the rest of their body, but best guess is a week-old give or take a day. This would also match up with nest observations we made over April; our estimated hatch date was the 22nd. Returning the following week further confirmed our age estimate as their little heads were still relatively bald.
Both Plémont parents are now out and about in search of food for their young. Concerns were raised when we started seeing both parents at the Sorel supplemental feed desperate for food. Choughs nesting at Plémont do not normally return to Sorel until their chicks fledge or the nest fails. This was the first time in five years. Chough chicks devour a lot of insects whilst in the nest, so chough parents tend to forage close-by to conserve their energy.
There has been a big increase in footfall at Plémont this month which could deter the choughs from foraging close-by. It has also been relatively dry so the soils around Plémont are not as favourable to soil-dwelling invertebrates. There are many other reasons why the parents might be visiting Sorel, the good news is that the chicks are still alive and begging well.
All being well the chicks should fledge at the end of May, start of June. We will be monitoring more closely this year around the fledging period. Last year we knew that two of the three chicks fledged, but don’t know what happened to the third. Then one disappeared within the first week of being out. If that happens again this year, it would be good to try and understand why.
Potential success at Ronez once again
We believe at least five of the eight nests in the quarry have chicks. This is based on behaviour of the pairs at the feeds and in the quarry. The females had been suspiciously absent. Then when they did turn up, they were very noisy. Pyrrho and Icho in particular would fly in vocalising, then follow their partner like a noisy shadow demanding food and being fed instantly. It’s quite an interesting sound they make trying to beg and swallow the food at the same time!
At the end of the month, we were then seeing the male and female in a pair making repeat trips between aviary and nest site. This tends to be when they are feeding chicks although we have no definitive proof yet. We are trying to arrange a quarry visit for May.
Our Jersey Zoo pair also had success this month with their first chick hatching on the 28th followed by number two the next day and number three shortly after.
There was a fourth egg…spoiler alert…it failed to hatch. The nest camera shows the parents still holding out hope until May 2nd. Mum took the executive decision to remove the egg from the nest around lunchtime. You can see this in the video below around 40 seconds in.
We may send the chicks over to the UK shortly after they fledge so they can become part of the release project in Kent. This is very much dependent on the Jersey and UK Government’s rulings over exports and imports of birds from a bird flu protection zone. Restrictions for indoor housing of poultry will be lifted in Jersey on May 9th.
No success in the new territories
The Trinity pair appear to have abandoned their nest and are spending more time at Sorel. They still visit the stables but the nest is now being used by doves. We had hoped that the choughs had found a more favourable site in the Parish yet their casual behaviour at the aviary suggests they’ve given up.
An article will be published in the summer edition of the Trinity Tattler magazine asking residents to report any sightings. This might shed some retrospective light on the situation. I’m not holding out hope that there will be a surprise nest discovered.
In similar circumstances, we are now seeing the ‘Corbière pair’ back at Sorel. Their suspected nest was last seen being used by pigeons. We are used to seeing choughs fail at establishing territories in the south west. Food supply, or lack thereof, may play a role in this. The cliff tops are choked with invasive sour fig (or Hottentot fig) (Carpobrotus edulis) and the exposed ground isn’t very accommodating to soil invertebrates.
Return visit to Guernsey
We have seen another report of chough posted on the Guernsey Birdwatching Facebook group. Dated 16th April, it is clear that the bird is one of ours from the red and white striped ring, but that is all we know unfortunately. They were foraging at Pleinmont again. Clearly a popular site.
It just so happens that Portelet and Archirondel were missing from the Sorel feed that day. Coincidence? This is very exciting news if they have made a second round trip between islands to forage.
Boring but necessary aviary stuff. April has brought sea fog, hail, downpours of rain, but mainly sunny days perfect for grass growing which means we do lots of grass mowing; weekly almost daily depending on how much time we have spare and how long the strimmer battery lasts.
The holes in the netting we had repaired earlier in the year have reopened with extra wear and tear. Nothing to do with rodents just weathering and strain on the netting. We need to get the henchman ladder back up to Sorel to carry out the repairs.
We have replaced a couple of rotting hatches, rusted door bolts, replaced food stands and repaired benches for accessing hatches.

This will be my last chough report for Birds On The Edge and Durrell. I’ve been with Durrell for eighteen years and worked with the choughs since they arrived in the Zoo in 2010. It was a hard decision to make as I’m leaving both my job and the island I’ve called home for the last sixteen years.
I’m not quite leaving the choughs though as I will be taking up a new role as chough release supervisor in Kent for The Wildwood Trust. No doubt I will keep popping up from time to time on Birds On The Edge or at the Inter-Island Environment meetings. Like Where’s Wally minus the red and white striped top.
I’m extremely proud of what the team has achieved over the years, and I often forget letting the day to day stresses of running the project take over. Plémont is the perfect place to remind me. When I first visited the bay in 2006, I didn’t know the Channel Islands were once home to choughs. Eight years later I remember visiting Plémont café with friends and musing over the idea of one day seeing the then recently released choughs utilise the cliff tops and caves. And now, well why don’t you find out for yourself. Head to the café (I recommend the waffles), sit outside, soak up the rays, and listen…
