Photos of different aged Short-toed Eagle chicks are made by Jean-Pierre Malafosse and are published now by courtesy of the author.
They can be helpful to researchers for estimated determination of the chicks’ age.

In 2002 Jean-Pierre Malafosse /map/ and Bernard Joubert /map/ managed to unionize French Short-toed Eagle lovers. We would like to point to in a sense the composite work that is known by the name of La Plume du Circaète – (Fr) {rough translation} and was realized in 2003 by the agency of the Ligue pour la Protection des Oiseaux (source – LPO Mission Rapaces page). Now the second pdf-file – La Plume du Circaète #4 – (Fr) {rough translation} is available too.
This is one more general information on the species:
• MALAFOSSE J.-P. et JOUBERT B., 2004 – Circaète Jean-le-Blanc Circaetus gallicus (Gmelin) 1788 // in Thiollay J.-M. et Bretagnolle V. (coord.), Rapaces nicheurs de France, Distribution, effectifs et conservation, Delachaux et Niestlé, Paris: pp. 60-65. (Fr).
…but, Jean-Pierre Malafosse with group of researchers had traced more than 400 cases of Short-toed Eagles breeding just till 2000 in the so-called Massif Central /map/. And their researches are continuing. Just think about it…
Bernard Joubert /map/ is an author of the “Le Circaète Jean-le-Blanc” book; see an extract from it (Fr) about the youngs’ behaviour after leaving the nests.
