“The Iberian Green Frog has been an interesting amphibian to follow. After walking a mile up a drought stricken Alentejean river in May i came across a shallow body of water only an inch or two deep. To my amazement there were at least fifty of these surviving. Lying down in the water I waited for them to come to me so being patient and not flushing your subject is a crucial part of being a wildlife photographer”
