We would like to present a work of Georgiy Petrovich Dementiev published in 1932 in Ornothologische Monatsberichte:
• G. Dementiew, 1932 – Bemerkungen über die geographische Variation des Schlangenadlers [Comments about the geographic variations of Short-toed Eagles] // Ornothologische Monatsberichte, Bd.40, № 6, S.172-173. (De).
This work was dedicated to geographical variations of Short-toed Eagle. The Circaetus gallicus heptneri subspecies was described in the article. It is more often considered now as a clinal variation, but however the article is still of interest and therefore it has been translated to English and to Russian with help of our friends.
Just a little notice: to make easier communication between Short-toed Eagle watchers and researchers a special contact group has been established under the name of CGCG – Circaetus Gallicus Contact Group. Visit please this page for further information…
