New Year, new adventures. That appears to be the motto of the juveniles, in particular the foster chicks who have taken a liking to the bay at Le Pulec, known to locals as “Stinky Bay”. This area is just below Battery Moltke, Les Landes, where we reported the choughs were last month. So not a surprise, but certainly an interesting addition to their home range. The bay has plenty of rotting seaweed, hence the name, harbouring insects attractive to many shorebirds. Are the choughs also exploiting this food resource as Scottish choughs do?

So far our observations suggest not. Trying my best to avoid analogies to a certain president and his wall, there is a current divide between the shore birds foraging below the sea wall defence and the choughs probing the loose soil on the other side.

That may change as January’s freezing temperatures restrict the amount of food available in the coastal grassland forcing the choughs to look for alternative sources. The choughs were definitely more hungry this month than last. Wing-begging at staff is just one way to determine how hungry each individual is. Having the entire group of 35 stalk staff from the public car park along the cliff path to the aviary shows just how little wild food is available. They also had a great desire to cache food in preparation for the cold days that lay ahead. Something I think the magpies have cottoned on to as I observed a pair promptly dig up a stash once the unsuspecting chough had left.

The first time the juveniles were spotted alone at Le Pulec there was concern that they might not have the gumption to make it out of the bay and back to the aviary. Would they find enough food in the bay?

I had spent the first hour of the morning above the bay at Les Landes trying to pinpoint the radio signals.  When I arrived at Le Pulec car park and walked around to look across the bay I could make out six chough shapes on the cliff face, but couldn’t identify them. Until that is, they took to the air calling excitedly and four choughs flew over to land behind me within 5 metres of where I stood.

In a roll-call fashion I ticked off Ubé, Wally, Vicq, and Xaviour, i.e. the four foster chicks, from the list of missing choughs. Once they realised I had no food for them they re-joined the other two juveniles in the bay.  By 10:50 I had to leave so I could put the supplemental feed out at Sorel. On arrival at Sorel twenty minutes later the entire flock greeted me, headed up by none other than Ubé, Wally, Vicq, and Xaviour!

This demonstrates how well the birds have learnt to associate the aviary with food, how they can map out the land, and how they somehow know what time it is!

The older choughs have also been spending more time away from Sorel although they don’t seem to wander as far. Crabbé is still a favourite for them. They like flying around Plémont and have been seen at Les Landes, but in terms of foraging they prefer to stay within sight of Sorel.

Lee and Caûvette are still doing their thing over at Les Landes in the mornings. Inching far too close to peregrine territory for our liking. Especially now the juveniles are following their lead.

There is another pair, Bean and Kevin, who have started playing truant at the morning feed although not as frequent as yet to suspect anything. We may struggle in future weeks to identify individuals as some of the plastic rings are snapping off. Notably breeding males Dingle and Green have lost rings. Once the repair work on the aviary is completed, we should be able to trap birds inside once again allowing rings to be replaced before the breeding season kicks off.

Bird flu precautions

With cases of bird flu being declared in France and the UK we are taking various precautions within the Zoo to minimise the threat to our collection in Jersey. For this reason staff working on the chough project are changing footwear when entering zoo grounds, a disinfection footbath and separate wellies are in use at Sorel aviary, and chough food is being prepared away from the Zoo Bird Kitchen to reduce any potential cross-contamination.

To date bird flu has not been recorded in the Channel Islands. However, the States Vet is asking Islanders to be cautious and follow recommendations including reporting dead birds to the States Veterinary Office. Click here for more information.

Free-falling for choughs!

Simon Inman, our current student placement on the chough project, is loving his time at Durrell so much that he is going to jump 10,000 feet from a plane!

Student Simon Inman is raising funds for the choughs and Durrell through a sponsored skydive.

That sentence might need re-wording, but essentially Simon is going to do a skydive in summer and would like to raise funds for the choughs at the same time. So if you would like to support the choughs, and Simon’s craziness, please click here to visit his JustGiving page and donate.

His fundraising target is £150 which will pay for camera equipment for the nest box in the display aviary at the Zoo. We hope to set up a wireless network to send live footage direct to a PC and our smartphones.

Last year, the pair in that aviary successfully reared two chicks for the first time. A third unfortunately died. We might have been able to save it if we could have observed nest activity in real time and intervened at the first sign of decline.

Any donations will be gratefully received.

Plus, if you all donate money it makes it harder for him to back out at 10, 000 feet in the air!
