ALBANY,
N.Y. (AP) — A coffee table book and documentary by a Cornell Lab of Ornithology
scientist and a National Geographic photographer provide a rare glimpse of the
extravagant plumage and bizarre courtship dances of the rainforest birds known
as birds-of-paradise.
Cornell's
Ed Scholes and photographer Tim Laman made 18 expeditions to the remote
rainforests of New Guinea over eight years.
Their
goal was to document for the first time all 39 species of birds-of-paradise in
the wild with photos, audio recordings and video.
"Identification
of species of birds-of-paradise has been going on for a long time because
they're so beautiful," Scholes said.
"There's
a good sampling of them in museums around the world from 19th century
collectors who would go and shoot them or buy them from local people."
Most
of the photographs of the birds were from captive birds in zoos.
Photographing
them in the wild is challenging because of the rugged, hard-to-access areas
where they live, and because many of the courtship displays happen high in the
treetops.
Laman,
an expert tree-climber, built platforms high in the rainforest to photograph
those species.
Food
is abundant and predators virtually non-existent in the New Guinea rainforest
where birds-of-paradise evolved.
So
the main driving force for evolution was sexual selection, said Scholes, whose
primary interest is evolutionary biology.
The
birds evolved with incredible colors and behaviors designed to attract mates.
Some
can change instantly into a flared-skirt dancer or a bouncing blob with
luminous, blinking color patches. Some have long, ribbon-like head feathers, or
waving, wire-like feathers tipped with shiny disks.
"My
favorite would probably be the superb bird-of-paradise," Scholes said.
"I
still look at it and find it too incredible to be true.
“The
male transforms himself from a fairly recognizable black bird into something
completely otherworldly, a black ovoid shape with what looks like two
iridescent eye spots and a mouth — what I call a psychedelic smiley face."
Laman,
who lives in Lexington, Mass., and maintains an academic affiliation with
Harvard, where he got his doctorate in biology, said his favorite is the
greater bird-of-paradise.
The
male is stunning: maroon with a silver iridescent crown, blue bill and a
cascade of brilliant yellow display feathers at its flanks.
But
it's not the bird's beauty as much as its backstory that captivates Laman.
"We
went to a remote place called the Aru Islands, where we were following in the
footsteps of one of my real heroes, Alfred Russel Wallace," Laman said.
"He
was a contemporary of Darwin who in the 1850s was exploring this area of
Indonesia.
“He's
known for discovering the same theory of natural selection as Darwin, and
writing to him about it."
Laman
and Scholes put more than 2,000 video clips and many audio files of
birds-of-paradise in the Lab of Ornithology's Macaulay Library.
The
collection is available online.
A
documentary on the project will air Thursday evening on the National Geographic
Channel.
