Meet an Australian supermodel for the ages: six toes tall with a sculptured visage, limitless legs and piercing orange eyes.
“They’re the glamour animal for the rainforest, right here in North Queensland,” mentioned Justin McMahon, a land supervisor for Rainforest Rescue, an environmental nonprofit that protects and restores the Australian rainforest.
However the southern cassowary, a secretive, emu-like chook famed for its killer kick and razor-sharp, throat-slitting talons on every foot, isn’t only a fairly face.
Because the draft of a authorities restoration plan for the species launched this week describes, the birds are what is called a “keystone species,” indicating that they play an vital position within the ecosystem.
From an environmental perspective, maybe their most vital attribute is their position as seed dispersers. Cassowaries use their large gape to gulp down complete fruits directly, and their highly effective legs to move these seeds (secure inside their bellies) far and large. And, weighing in at 130 kilos, they’ve spectacular appetites, permitting them to devour giant portions of fruit, in addition to the rest they’ll scrounge.
(Additionally they have a softer aspect: Cassowary males make doting dads, sitting on the clutch of eggs for nearly two months, then taking the first parental position for the primary 9 months of their chicks’ lives.)
Southern cassowary populations have been noticed to be declining for nearly 80 years, and the species was formally listed as endangered in 2000.
On the time of that itemizing, the birds had been notably in danger from their habitat being cleared. 1 / 4-century later, they face different threats: street visitors; canine and dingoes; “habitat fragmentation,” the place their pure rainforest is damaged up they usually can not simply transfer between areas; and local weather change.
It’s onerous to determine fairly how threatened they’re, and even what number of there are, although estimates run from about 4,000 to 10,000 throughout northwest Queensland, the one a part of the nation that they stay in, Mr. McMahon mentioned. “Nobody will ever know a great quantity, sadly.”
That’s as a result of the southern cassowary, for all its fearsome fame, is powerfully shy, and remarkably good at making itself scarce. Regardless of standing six toes tall, the birds have been recognized to face inside spitting distance from vacationers with out being noticed — partially as a result of they’re so completed at conserving very nonetheless.
Mr. McMahon describes them as being extra “emo” than “emu.” “They stay of their darkish abyss of the rainforest, they usually don’t like being regarded on the mistaken manner or talked in regards to the mistaken manner,” he mentioned.
Makes an attempt to trace them with geolocation trackers are inclined to fail — they’ll merely peck off something hooked up to their physique — and their solitary methods could make their behaviors onerous to check.
However it’s clear that human beings are taking their toll on the animals. Because the variety of vehicles within the area has risen, partially the product of extra self-driving tourism, some birds have been the victims of hit-and-runs.
Local weather change has additionally had an impact — increased temperatures can result in springs and puddles drying up, creating stress for the chicks.
In hotter years, the animals’ breeding seasons are longer, permitting “homewrecker” females the chance to lure single dads away from their brood and onto a brand new clutch of eggs. The chicks, stranded and orphaned, generally method people as substitute dad and mom.
However whereas cassowary infants are undoubtedly cute, with hanging stripes and fuzzy our bodies, they may not be the form of creature you need to have in your house for the lengthy haul (as a Florida cassowary proprietor found in 2019, at a horrible price).
Now for the week’s tales.
