Just received a book published by WWF Greece, which includes a selection of scientific papers regarding the famous Dadia raptor reserve in North-eastern Greece. It is actually a systematic presentation of all studies carried out on this area over the last 20 years. I was privileged to be commisioned to illustrate this book. All of the drawings have been done using a simple BIC ballpoint pen. Attached, few of the illustrations..... Griffon vulture
