Laughing Owl - Sceloglaux albifacies
Also known as Whekau, White-faced Owl
The laughing
Owl was endemic to New Zealand, but is
probably now extinct. European settlers first arrived in New Zealand in 1840,
when the laughing owl was plentiful. Specimens of the laughing
owl were sent to the British Museum where reports on them were published in 1845.
By 1880, they were becoming rare, and the last specimen recorded was found
dead at Blue Cliffs in Canterbury in 1914. There have been unconfirmed reports
of laughing owls since then, but no specimens. In his book "The Wandering Naturalist",
Brian Parkinson describes reports of a laughing owl in the Pakahi near Opotiki in the
1940s.
Laughing Owl egg fragments were apparently found in Canterbury in 1960.
Extinction was caused by
persecution, land use changes and the introduction of predators such as cats
and dogs.

Description: Plumage
was yellowish-brown striped with dark brown. There were white straps on the
scapulars, and occasionally the hind neck. Mantle feathers were edged with
white. The wings and tail had light brown bars. The tarsus had yellowish to
reddish-buff feathers.
Facial disc was white behind and below the eyes, fading to grey with brown
stripes towards the centre. Eyes were dark orange.
Size: Length
35.5-40cm (14-15.7"). Wing Length 26.4cm (10.4")
Voice: Various
descriptions exist for the song of the Laughing Owl:
"A loud cry made up of a series of dismal shrieks frequently repeated"
- this sound gave the Laughing Owl its name.
"A peculiar barking noise... just like the barking of a young dog"
"Precisely the same as two men "cooeying" to each other from a distance"
"A melancholy hooting note"
Others describe the call as a high pitched chattering, only heard when the
birds were on the wing and generally on dark and drizzly nights or immediately
preceding rain.
Various whistling chuckling and mewing notes were observed from a captive
bird.
Hunting & Food:
From studying pellets, it has been determined that these owls ate beetles,
lizards, small birds, rats and mice. Laughing Owls were apparently ground
feeders, chasing prey on foot.
Breeding: Began in September or October.
The nests were lined with dried grass and were on bare ground, in rocky ledges,
fissures or under boulders. Two white, roundish
eggs were laid, measuring 44-51 x 38-43 mm (1.7-2" x 1.5-1.7"). Incubation
took 25 days, with the male feeding the female on the nest.
Habitat: Generally
Rocky, low rainfall areas. Also in forest districts on the North Island.
Distribution: North
Island: Specimens were collected from the forest districts of Mt Egmont (1856)
and Wairarapa (1868). Sighted in Porirua and Te Karaka. According to Maori
tradition, they also occurred in Urewera.
South Island: Low rainfall districts - Nelson, Canterbury and Otago. Also
Central mountains and possibly Fiordland. Specimens were collected from
Stewart Island in 1880.
Status: Extinct
