About this place
Explore Gondwanan angiosperm refugia, Casuarius casuarius keystone megafaunal frugivory, casque thermoregulation, and infrasonic booms.
For kids: Step into Earth's oldest rainforest—where dinosaur-like cassowary dads plant giant plum trees and rumble deeper than piano keys!
Daintree Ancient Forest & Cassowaries · 360° Habitat Camp
What to look for
- Circular-frond Licuala fan-palm gallery — 180 Ma Gondwanan angiosperm refugium. Centre the Licuala ramsayi understory amidst basal Gondwanan angiosperms
- Fallen blue-quandong & plum trail — Casuarius casuarius obligate endozoochory. Locate the forest-floor frugivory trail where >70 large-seeded species depend on cassowaries
- Mossy rainforest creek & boom corridor — 23 Hz acoustic transmission & casque radiator. Scan the dense creek corridor carrying 23 Hz booms and cooling humid air
Source: Mack et al. (2003), Auk — Low-frequency ~23 Hz cassowary booms; Eastick et al. (2019), Scientific Reports — Casque thermal window; Bradford & Westcott (2010) — Keystone seed dispersal.
Ask together: Why do giant rainforest fruits in the Daintree grow bright blue and purple coats—and why do they need a bird as big as a grown-up to carry their seeds?
Field quiz
Kids' question: In a southern cassowary family, who sits on the bright green eggs and teaches the striped chicks where to find fruit?
- The devoted dad cassowary—all by himself for nine months!
- Tree kangaroos hired as babysitters
- Nobody—chicks fly away the moment they hatch
Answer
The devoted dad cassowary—all by himself for nine months!
Adults' question: What primary physiological role did thermal thermography (Eastick et al., 2019) reveal for the tall spongy casque atop a cassowary's head?
- A controllable vascular 'thermal window' dumping excess metabolic heat in hot rainforest air and conserving heat in cool weather
- A solid bone battering ram used to knock over mature kauri trees
- A hollow snorkel tube for breathing at the bottom of rivers
- An echolocation dish for catching flying microbats
Answer
A controllable vascular 'thermal window' dumping excess metabolic heat in hot rainforest air and conserving heat in cool weather
