As a child, Antonio Segura Donat (Dulk) helped his father to feed the birds they reared at their home. He loved watching the fledglings and seeing them grow, as well as the fish, dogs, and horses that lived on the property. When he wasn't out and about, he copied illustrations of exotic animals that he found in his parents' collection of old enciclopedias. And he took his sketchbook with him everywhere from then on.
