It was breeding season when I visited Iceland in early June. I passed by the southernmost town, Vik and learned from the local guide that the island of Dyrhólaey was closed until late June during nesting season. I took a walk on the black beach and saw a few puffins flying over the nearby Reynisdrangar cliffs. They looked a bit clumsy and quite funny when flying. According to the guide, the puffin population is in sharp decline because rising temperatures of surrounding waters are driving away their food sources. Additionally, humans remain the biggest threat to these puffins. They are hunted for food and eaten, fresh or smoked. Raw puffin heart is eaten as a delicacy in Iceland.
