Physical description Click here for a physical description Pallid Cuckoos are large cuckoos. They have a light-grey front (throat, chest and belly), a vent and undertail coverts barred in shades of grey and the typical heavily barred grey-and-white undertail of many Australian cuckoo species. The frons, crown and back are grey. The eyes are surrounded by a yellow eye-ring, which is located within a black eye stripe. The wings are scalloped grey, with dark-grey flight feathers. Males are always grey, some females can have an hepatic morphology, with a chest scalloped in shades of rufous-brown, and the head and back, including the wings, in shades of brown and dark-brown. Immature Pallid Cuckoos that have moulted into adult plumage almost all over, retain one small light-grey spot on the nape of the neck until they are mature. Juvenile Pallid Cuckoos are heavily scalloped in shades of brown and grey all over the body and their tail is barred like that of adult birds. All Pallid Cuckoos have dark irises, a black bill and grey legs and feet. The wings have the narrow white leading edge on the shoulders typical of many Australian cuckoo species.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Pallid Cuckoo is available HERE . Apart from Australia, Pallid Cuckoos are only found in Timor Leste. Pallid Cuckoos are migratory. During their breeding season they are found primarily in the South-East of Australia (Tasmania, VIC, NSW and south-eastern QLD) and the South-West (the south-western corner of WA, up to about Geraldton, but also inland up to the tropic of Capricorn near the spring of the Fitzroy River). Outside their breeding season they disperse, vacating the south-eastern parts of the continent and populating most of the NT and SA and the Kimberley in WA. They are occasionally found in the rest of the continent as well, except the most arid part (the major sandy deserts of eastern WA). They are also found on numerous offshore islands. Pallid Cuckoos are usually found in forest or more open woodland and on farmland with scattered trees.

Sightings Click here for sighting information Pallid Cuckoos showed up where we lived in 2003-2006, 20 km South of Narrabri, NSW, only occasionally. In general, we see Pallid Cuckoos only infrequently around Narrabri, NSW, although they are common, at least during the winter months, in southern inland QLD. At Eulah Creek, 20 km East of Narrabri, NSW, a Pallid Cuckoo appeared in August 2010. In 2011, again a single Pallid Cuckoo was seen in the third week of August. Migrating only inside Australia, they appear further South again earlier than other migrants that cross the Torres Strait. In 2011 these Australian migrants probably rode the northerly winds of a weather system that brought rain to inland NSW in mid-August. In 2016 the first Pallid Cuckoo of the season was again heard in late August, ahead of a rain event. Pallid Cuckoos are seen by us there semi-regularly since. An immature bird was found in the garden in May 2017, which is very late for this migratory species. Pallid Cuckoos were scarce during the drought of 2018/2019 and the first in a long time was found in March 2020. J. Greaves reports spotting a Pallid Cuckoo at the Granites Gold Mine, inland NT, in June 2015, and at Boolardy Station, Murchison, WA, in August 2016. M. Eaton reports spotting a Pallid Cuckoo at Goondiwindi, QLD, in March 2018, and another at Atkinson Dam, near Lowood, QLD, in October 2019. R. Plumtreereports finding an immature Pallid Cuckoo between Berri and Renmark, SA, in September 2018. Lots of Pallid Cuckoos were found by us in various locations around Outback south-western QLD in June 2019.

Breeding information

As all cuckoos, Pallid Cuckoos host on smaller bird species. One potential host species is the White-plumed Honeyeater.

Behaviour

Food, Diet

Like most other cuckoos, Pallid Cuckoos are insect hunters. They take their prey from foliage and from the ground. This species has a taste for hairy caterpillars, which most other birds dislike.
