AUSTRALIAN STONE CURLEW
Burhinus grallarius
DESCRIPTION
Australian Stone Curlew (Burhinus grallarius) is also known as the Bush Stone-Curlew and Thick-knee. This large, ground-dwelling bird features long legs, a long neck, and a distinctive large eye, which gives it excellent night vision. It is primarily nocturnal, often seen foraging at night and relying on its cryptic plumage for camouflage during the day.
FUN FACTS
- Australian Stone Curlews are known for their unique vocalizations, which can sound quite eerie at night, often described as a haunting call that echoes through the bush
- They have a fascinating behavior of freezing in place when threatened, relying on their camouflage to avoid detection by predators.| These birds are also known for their unusual nesting habits, often laying their eggs directly on the ground without any nest structure, which makes them vulnerable to predation but allows them to blend seamlessly into their environment
