Northwest to the town of Eyrarbakki is a wetland area, rich in birdlife. The reserve has walking paths and a bird hide, an ideal spot for bird watching.

The Flói Bird Reserve is listed in the Bird Life international Association. The Reserve is characterized by its flood meadows and numerous small ponds. Approximately 70 species of birds have been recorded in the Reserve.

During spring and autumn migration Greylag Geese and White-fronted Geese can be found as well as Wigeon and Tufted Duck and various waders such as Snipe and passerines like Wheatear. During winter, birds, chiefly gulls and sometimes Long-tailed Duck and Common Eider, are concentrated in the estuary of the river Ölfusá.

Whooper Swan, Teal, Mallard and Goosander are attracted to open water in winter.
