Widespread but uncommon throughout a large part of New Guinea, the shovel-billed kookaburra is evaluated as Least Concern on the IUCN Red List of Threatened Species. Shovel-billed kookaburra The shovel-billed kookaburra ("Clytoceyx rex"), also known as the shovel-billed kingfisher, is a large, approximately 33 cm (13 in) long, dark brown tree kingfisher with a heavy, short and broad bill that is unique among the kingfishers.

Carnarvon Gorge humans, due to hand-feeding which is against Park regulations. This situation is of concern to Park rangers as it allows opportunistic species, such as the laughing kookaburra ("Dacelo novaeguineae") and the pied currawong ("Strepera graculina"), to develop population sizes that are abnormally large. When visitation (and therefore hand-feeding) tapers off over the summer low tourism season the abnormal populations place abnormal pressure on the species' natural food sources which can include the young of other bird species. Australian bustards ("Ardeotis australis") are frequently seen in farmland on approach to the Gorge, along with brolgas if the weather has been wet.
