Herald petrel

The bird is in size, with an wingspan. It was formerly considered conspecific with the Trindade petrel and Henderson petrel. This petrel has various colour morphs: dark and light, as well as intermediates between the two. ==Habitat and range ==

The Herald petrel nests on oceanic islands and atolls, on cliff ledges, ridges or rocky slopes. On some islands, nesting birds are threatened by feral cats and rats. Found primarily in the south Pacific, it has been seen in Hawaii. In May 2007, a Herald petrel tagged on Raine Island in 1984 was observed off the coast of Mauritius in the Indian Ocean. This greatly increases the known life span and range of the species. In August 2017, Queensland Parks and Wildlife Services (QPWS) staff confirmed a Herald petrel chick had hatched on Raine Island after sighting an adult Herald petrel taking care of a single egg in a nest in June 2017. The sighted chick was the first time a Herald petrel was seen to breed in 30 years. Raine Island is the only known Herald petrel breeding site in Australia. ==Conservation status==

This species is evaluated as "Least Concern" on the IUCN Red List of Threatened Species. A 2018 study ranked the species ninth in a list of Australian birds most likely to go extinct. ==References==
