Dear colleagues,

I would like to share with you a recently published article in the Journal of Raptor Research describing a rare breeding case of Egyptian Vulture in a nest with three nestlings recorded in Menorca.

In this letter, we document and describe this exceptional reproductive event, which represents a very uncommon outcome for the species, and place it in its appropriate ecological and conservation context.

I would like to sincerely thank all of you who contributed by sharing interesting observations, unpublished information, and personal communications on other cases of Egyptian Vulture nests with three nestlings reported worldwide. These contributions were essential to contextualize the rarity of the Menorca case and to strengthen the manuscript.

You can find the publication here https://www.researchgate.net/publication/399456614_A_Successful_Breeding_Case_of_an_Egyptian_Vulture_Neophron_percnopterus_Nest_with_Three_Nestlings

Many thanks again for your support and for the continuous collaborative spirit within the Egyptian Vulture community.

Best regards,

Pascual

Dear Pascual

Thanks for sharing this interesting case report .

However I wonder why you don’t discuss the potential influence of food resources in such high productivity, a determinant factor as you know.

Many years ago we reported an exceptional case of two fledglings Bearded vultures in Ethiopia in a context not only of high density but also of very abundant food resources in the Balé mountains (Barrau C, Clouet M & Goar J.L. 1996. Alauda 199-201).

Unfortunately we don't have such good results neither for Egyptian nor Bearded vultures in the Northern Basque country.

Best regards.

Dear Michel,

Many thanks for your message and for pointing us to that reference on Bearded Vultures in the Bale Mountains. 

You are absolutely right that food availability is a key determinant of reproductive output, and we fully agree that trophic conditions in Menorca likely play an important role. However, given the format of the paper (a short letter), we were limited in the scope of the discussion and had to focus mainly on documenting the exceptional nature of the case itself.

That said, if food availability alone were the main driver, one would expect to detect many more cases of Egyptian Vulture nests with three chicks in Menorca, considering the long-term monitoring effort and the generally favourable trophic conditions on the island. The fact that such cases remain extremely rare suggests that additional factors (demographic, individual or stochastic) are probably involved.

Thank you again for your thoughtful comment and for sharing your work. 

Best,

Pascual
