As a National Marine Park and situated in the Great Barrier Reef Marine Protected Area, Heron Island is an important habitat for many species. A variety of wildlife visit the island at different times of the year, depending on breeding, foraging and migratory movements.

As a visitor to Heron Island you may experience unforgettable encounters with the amazing wildlife that also shares the island. Our Naturalist Guides encourage you to learn about the flora and fauna of the island and witness activities such as nesting and hatching, during guided tours.

Through all but a few months, Heron Island is a breeding and nesting sanctuary for a huge variety of birds. The biggest populations are the Black Noddy Terns (Anous minutus), Wedgetailed Shearwaters (Puffinus pacificus) and Eastern Reef Egrets. In certain months, up to 100,000 birds flock to the island.

Depending on the time of your visit, you’ll see a variety of adult birds, and potentially witness as young birds emerge from their burrows.

Bird nesting holes are protected with covering boards, as the nests are often found in the middle of a trail or path. If you come across a covered or uncovered nesting hole, please do not tamper with the hole, which can disrupt the hatching process and disturb the nesting birds.

Unlike many destination resorts where you’ll have to travel far from your accommodation in order to explore nature, Heron Island offers a relaxing retreat for both humans and natural wildlife.
