Photos of Short-toed Eagles of certainly known age and sex

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.
