Circaetus gallicus information navigator

Dear Circaetus gallicus lovers and researchers! Let us, please, invite you to contribute your photos (info@short-toed-eagle.net) of the Eagles of age and sex known for certain. These photos will be inserted into the special gallery which has been created on initiative of Francesco Petretti. We aim to make something like an online handbook to help to describe differences between sexes and ages of Short-toed Eagle and finally to make their field identification easier. Each contributed photo should be supplied with information, examples of which can already be seen below each inserted image.

A projected model of the plumage changing for Short-toed Eagle has been made by me for discussion and rectification by comments from the practising observers. This aims to make easier field recognizing of different ages of Short-toed Eagles for birdwatchers.

Heartful thanks to Javier Blasco-Zumeta for few fullsized illustrations to his information sheet! They are represented below:

Visit please Javier Blasco-Zumeta’s site to find some information on identification of birds in nature. This information sheet – (En) on two pages with demonstrative photos (moult and age-specific changes) – could be helpful in the field together with article of Guido Premuda and Andrea Corso about the plumage characters. Also we have the fullsized illustrations to view the plumage more particularly.

Please read the text written by Guido Premuda together with Andrea Corso dedicated to determination of Short-toed Eagle’s age and sex by plumage characters: Il piumaggio del Biancone: età, sesso e morfismo (It) which could be used as a hand book for the field work.
Also the photo and a list of full texts of Premuda’s articles dedicated to Short-toed Eagle can be found here (the source is his own website – Sunbird.it):
