Cicadas singing
Not a bird this time, but a beetle that makes bush walking painful to the ears in the summer months around Sydney. The piercing noise of cicadas is familiar to most Sydney-siders. In this video, you can hear them all round you, and see one close-up pulsating its abdomen to make the noise.
The insect is quite large – about the length of your thumb – and has transparent, lacy wings:
Their huge eyes make them look super cool, as if they’re wearing sun glasses:
An interesting fact: The adult cicada is the winged insect we see, and it lives for only a few weeks. But the nymphs, which are the form of the creature that hatch from the eggs, live for around seven years, underground.
A while back, I came across these cicada husks. When the nymph is ready to transform into the winged insect, it climbs up from the underground onto a bush or tree trunk and sheds its skin. These are the resulting empty husks:
Water dragon in a tree
Not a bird this time. This is an Australian water dragon – a reasonably large lizard that climbs trees and loves water. This one is about 60 cm long, the length of my arm without my hand.
I first spotted it when walking underneath the branch it was on. See the impressively long tail:
Here’s a side-on view. Apologies for the silhouette. The lighting was difficult:
