A keeper's house is occupied by a caretaker; another building may be rented for overnight stays.[3]

Birds

The island is home to the world's largest colony of little penguins.[2] Gabo, with the tiny associated islet of Tullaberga at its southern end, has been identified by BirdLife International as an Important Bird Area because of the numbers of breeding penguins (up to 21,000 pairs) and white-faced storm petrels (up to 20,000 pairs).[5] Concern of predation of native birds and animals led to a successful feral cat eradication program on the island between 1987 and 1991.[6][7]

Literary references

“The wind that blows by Gabo,” is the title of a poem by E.J. Brady.[8]
