Some weeks ago, Quercus<\/a>, a Portuguese NGO, set up a trap to catch adult and young vultures in the vulture feeding station at the Tejo <\/a>International Nature Park, as part of their scientific work. The aim was to identify, ring and extract biological samples to study the birds\u2019 condition. Among a flock of Griffon Vultures (Gyps fulvus<\/a>)<\/em>, they were far from guessing that a Cinereous Vulture (Aegypius monachus<\/a><\/em>) would also fall into the trap\u2026 And what a Cinereous Vulture it was! Today, we bring you an extraordinary story about vultures, zeal and great determination.\u00a0\u00a0<\/p>\n\n\n\n

40 years after extinction, Cinereous Vultures recolonised Portugal in 2010\u00a0<\/h3>\n\n\n\n

At the beginning of the 20th<\/sup> century, Cinereous Vultures were a common sight across the Iberian Peninsula. However, in the 1970s, direct persecution, habitat degradation and poisoning events plummeted the population and led to the extinction of Cinereous Vultures as a breeding species in Portugal. A decade later, understanding the dire situation the species was facing, conservation measures started being implemented in Spain, helping the population to slowly recover.  <\/p>\n\n\n\n

As the population grew in Spain, some individuals started venturing into Portugal. Finally, in 2010, the first two breeding attempts were recorded at the Tejo Internacional Nature Park<\/a>, a cross-border protected area and a haven for several raptor species. Two pairs settled in for the first time in 40 years! Both pairs successfully hatched one chick each; however, as their nest-building skills were still rudimental, the two nests collapsed when the chicks were still too young to fly.\u00a0<\/p>\n\n\n\n

How \u201czeal and great determination\u201d can change the course of a species <\/h3>\n\n\n\n

Carlos Pacheco, a conservation biologist who has been helping us ring Cinereous Vulture chicks<\/a> in the nest in Portugal within the LIFE Aegypius Return Project<\/a>, told us all about the two chicks that were born in 2010. Back then, he was on the team that was following the chicks\u2019 development, and he was the one who sounded the alarm: one of the chicks had fallen from the nest! <\/p>\n\n\n\n

Despite the best efforts, searches to find the chick on the ground were unsuccessful and it was thought that it was probably already dead. But Carlos did not lose hope. With zeal and a great determination, he returned one week later\u2026and found the chick!\u00a0<\/p>\n\n\n\n

Tejo, the Cinereous Vulture chick that survived one week on the ground\u00a0<\/h3>\n\n\n\n

Once a chick falls from the nest, its fate is often doomed: parents cannot bring the chick up, and the chick cannot withstand it alone. Carlos needed help to place Tejo (the name chosen for this survivor vulture) up in the nest as fast as possible \u2013 luckily, its parents were able to feed the chick on the ground during one week, as the area was open enough, but Tejo was exposed to predators. <\/p>\n\n\n\n

Carlos reached out to Paulo Monteiro (currently also working in the LIFE Aegypius Return project, at SPEA<\/a>) and Armando Carvalho (by then the regional director of the Protected Areas Department at the Institute for Nature Conservation<\/a>, ICNB), and gathered a group of about 10 people from various collaborating institutions, including Herdade da Cubeira, ICNB, Quercus\/CERAS. Altogether, they rolled up their sleeves and built an artificial nesting platform, very basic but safe enough to hold the birds\u2019 weight. After ringing the chick, they placed it on the platform… and the parents immediately started feeding Tejo again! \u00a0\u00a0<\/p>\n\n\n\n

Aravil, the second chick who also fell from the nest in 2010\u00a0<\/h3>\n\n\n\n

On the day Carlos and the team returned Tejo to the new nesting platform, they found the chick of the second pair \u2013 it was also on the ground. The chick was in very bad shape and was taken to the rehabilitation centre CERAS,<\/a> run by Quercus. Under the team\u2019s attentive care, led by Samuel Infante, the chick \u2013 named Aravil after the local river \u2013 regained its fitness and was ready to be returned. It was ringed with metal and PVC rings and was fitted a VHF transmitter, thanks to the support of GREFA<\/a>. \u00a0<\/p>\n\n\n\n

Carlos and the team tore down the collapsed nest and built a new one again. They were, however, advised not to put the chick back, as its parents would probably reject it after so long away from the nest. But the team was stubborn: they placed the chick back, and for a long week, they visited the nest daily (with a ladder) to feed the chick. Its parents, suspicious about the happening, were always seen in the chick\u2019s surroundings. Finally, one week later, they started feeding it again. Aravil eventually fledged and was followed for some time, while the VHS transmitter was active. Another happy ending!\u00a0<\/p>\n\n\n\n

Aravil was recaptured this year in Tejo Internacional Nature Park\u00a0<\/h3>\n\n\n\n

Thirteen years later, this very same Cinereous Vulture was caught in Tejo International, in December this year. Thanks to the ornithological ring, the Quercus team could identify the bird. With the support of the LIFE Aegypius Return, the Hawk Mountain Sanctuary<\/a> y ENDESA,<\/a> Aravil was now fitted with a GPS transmitter. We will now be able to follow his movements!\u00a0<\/p>\n\n\n\n

Capturing an adult Cinereous Vulture is always memorable, but this particular encounter was unique. It means that the chick survived thanks to the intervention of the stubborn team, and that he probably makes up one of the 44-46 pairs currently breeding in Tejo International Nature Park!\u00a0<\/p>\n\n\n\n

<\/p>\n\n\n\n

What would have happened to the species in Portugal without these interventions? <\/h3>\n\n\n\n

Cinereous Vultures are philopatric, like many other raptor species, meaning they tend to return to where they\u2019ve fledged once they reach sexual maturity. If it were not for the \u201czeal and determination\u201d of the team back then, the 2010 breeding season would have been unsuccessful and probably delayed the return of the species to Portugal. <\/p>\n\n\n\n

There are currently 78-81 Cinereous Vulture<\/a> pairs breeding in Portugal, which has doubled since the last known data from 2022. Thanks to the collective monitoring efforts of all LIFE Aegypius Return partners and collaborators, we now know the population is growing in all four Portuguese colonies.\u00a0\u00a0<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The project LIFE Aegypius Return has tried to capture adult Cinereous Vultures in Douro and Malcata but were unsuccessful. A trap will also be set in Alentejo, and Samuel Infante from Quercus \/ CERAS will also keep trapping and tagging adult birds, <\/p>\n\n\n\n

\n

\u201cit is essential we continue tagging adult birds with transmitters. This year, for instance, we had a poisoning case close the colony, where Cinereous Vultures forage\u201d.\u00a0\u00a0<\/p>\nSamuel Infante, Quercus – CERAS<\/cite><\/blockquote>\n\n\n\n

Tagging and monitoring adult birds can help us identify these incidents much faster and act effectively to prevent mortality. <\/p>\n\n\n\n
