Had a wonderful time at #BOUsci24!

A fantastic two days at #BOUsci24 discussing all things birds and translocations!
A big thank you to all those who presented, attended, and helped to organise the conference.

Captive bred vultures also showed reduced efficiency in their flight mode, spending more time soaring per meter progressed while gliding. Again, this effect was only seen in the first migration year.

Both groups migrated at the same time, followed the same routes to the same destination, but captive-bred vultures took ~40% more time to complete their first migration. The difference disappeared by the second migration.

The final presentation of #BOUsci24 comes from Ron Efrat, who is framing translocations as a pseudo-experimental design to study conservation and ecology.
The effects of captive vs. wild experiences on flight and migratory skills were compared in Egyptian vultures.

Reintroduction, captive breeding and conservation efforts in Nepal were hugely successful. Removal of diclofenac and promotion of safe drug use lead to improved survival rates and the declaration of the world's first safe vulture zone

Supplementary feeding stations are also used to influence movement post release, and to monitor birds behaviour and predator vigilance through cameras. As you can see, they are also used to monitor birds' weight.

Post-release monitoring is key to translocations. Best set of practices are outlined by the IUCN guidelines: portals.iucn.org/lib...
Monitoring is used to learn where birds go, what they eat, who they interact and to handle predator threats.

Birds go through behavioural training before release:
1️⃣ anti-predator training: www.sciencedirect.co...
2️⃣ foraging so they recognise native seeds, fruits and insects, and teaching them to use supplementary feeders
3️⃣ tracking social interactions:

World class veterinarians, nutritionists and avian care specialists work together to breed, raise and release this Hawaiian bird back to the wild. They were declared extinct in the wild since 2002 but it's been kept alive through dedicated conservation breeding

➡️ success definition and evaluation are rare
➡️ socio-political difficulties are common
✔️ A way forward? Pre-introduction local and stakeholder engagement is needed

Filippo Marino is talking at #BOUsci24 about conservation translocations as multidimensional programmes. Through a literature review, interviews and participant observations, the definitions and evaluations of raptor translocation success were evaluated

➡️ knowledge of storks and their status was limited in the wider population
➡️ storks were generally viewed positively, they were perceived as elegant and charismatic
➡️ high levels of public support were found
Reintroductions can help re-establish nature-people connections

CJ7 eventually paired up with translocated male 022 and in 2022 they became the first breeding ospreys in Southern England since 1847. In just three years of breeding they have reared 9 chicks, demonstrating the high availability of food in the local landscape.

One crucial individual to the emerging population has been a female from Rutland Water called CJ7, who was attracted to settle in the area merely by the presence of released young, long before any potential adult mates were resident in the area. Credit: @winspit1881.bsky.social

Seven individuals (and one wild fledged young) have so far returned to the UK, demonstrating the expected pattern of emigration by females bolstering neighbouring populations, and strong philopatry amongst males building the emerging local population.

Translocations have been implemented in many places to speed up range recovery, including in Poole Harbour, UK between 2017-2021 when a total of 38 juveniles sourced from the healthy Scottish population were released by @harbourbirds.bsky.social & Roy Dennis Wildlife Foundation.

A map showing Europe with orange covering North-eastern regions and a few small areas elsewhere, indicating the much reduced range of Ospreys due to persecution.
1/6 #BOUsci24 #SESH6
The Osprey suffered extensive historical declines throughout Western Europe due to human persecution, and has been slow to recolonise following greater protections due to high rates of natal philopatry and conspecific attraction.

Participating in the wonderful #BOUsci24 Conservation Translocation conference.
* Zoom conf really allow worldwide participation. Great to hear about so many works from Australia and NZ. Still missing many countries (Russia?).
* Conservation is a great way to know the world and its cultural diffs.

A happy 039 (a crane) and his love and their children.
Enjoying an absolutely fantastic talk by @RwandaWildlife 🐦 039 (a very special crane) has a new fan club 😍

If proven successful, this methodology could be used to not only to accelerate further range recovery elsewhere but also to reinforce declining populations around the British Isles whilst helping to improve their genetic diversity.

A photo of a grassy coastal slope with strip lynchets on the Purbeck coast where released Chough will hopefully be seen in the future.
5/6 #BOUsci24 #POSTER2
So @harbourbirds.bsky.social supported by the Roy Dennis Wildlife Foundation & Natural England propose a reintroduction to Purbeck using a new ‘wild-take’ translocation methodology, which favours genetic diversity, natural behaviours, and minimises costs & time requirements.

A map showing a modelled expansion of the Cornish Chough population towards Dorset over more than 40 years demonstrating the slow nature of the process.
4/6 #BOUsci24 #POSTER2
However spatial expansion of the Cornish population is slowed by low rates of dispersal and a lack of contiguous high-quality habitat along the South coast. It’s therefore projected to take between 34-80+ years for natural recolonisation to occur.
