This text about nesting Short-toed Eagles in the environs of Marseille as an example of the species adaptation to urbanization is offered by Richard Frèze:
• Richard Frèze, 2008 – Un Circaète aux portes de Marseille [Short-toed Eagle near Marseille] (Fr). Also you have a possibility to open a PDF 
{rough translation} of the article, to view /map//map/ and photos.
New personal site of famous French researcher, Yves Boudoint /map/, has been created. Among the sections there are many different photos of Short-toed Eagles, old and relatively new texts (Fr) and presentations of materials on CD and DVD dedicated to the birds. The site’s content tells its own story.
One of works of the oldest Short-toed Eagles researcher in France – Yves Boudoint /map/ – is represented below. This text describes some interesting details of biology of the species and includes notes on some traditional and untraditional methods of study:
• Yves Boudoint, 1953 – Etude de la biologie du Circaète Jean-le-Blanc [Study of the Short-toed Eagle biology] // Alauda, 21 : 86-112. (Fr).
This is the presentation of two old texts of the first part of the XX century. One of them was written by Viktor Zebe:
• Viktor Zebe, Oktober 1936 – Zur biologie des Schlangenadlers [Biology of the Short-toed Eagle] – Berichte des Vereins Schlesicher Ornithologen /map/. Just read the translation of it (Fr) from German made by one of the greatest adepts in Short-toed Eagles in France – Yves Boudoint.
The second is Nikolay Gavrilenko‘s work, that is mentioned in the first one:
• Гавриленко Н.И., 1929 – Птицы Полтавщины. Змееяд [The birds of the Government of Poltava. Short-toed Eagle] // Полтава: Издание Полтавского союза охотников: 28-30 (Ru) /map/.
