I spent a very pleasant hour by the sea in Peru with binoculars trying to sort out various species of coastal birds.
The most common were Franklin’s Gulls which, in summer, are losing their grey heads.






In this photo, a Kelp Gull (juvenile) is on the left and a Dolphin Gull (red legs and bill) is on the right.
