Oscar writes: While in the Doñana National Park we spent some time around the marshes by the visitor centre looking for some of the birds the area is known for, such as the White-headed Duck. One bird we saw many of was the Purple Herons, which were everywhere! This one flew past at close range, allowing for some photos.
