For the second time since I’ve moved to Toowoomba about a decade ago, we’ve heard the quiet wail of a Graceful Treefrog (Litoria gracilenta) in the back-yard. The sound brought back a few memories.
I used to look forward to the calls of these frogs during summer when I lived in Brisbane. As the air grew humid and the sound of distant thunder rolled across a still suburb, the rising wail of a Graceful Tree Frog would be heard coming from high up in the dark-green canopy of the old mango tree that took up most of my small backyard and which had the swing attached that my one-year old son was so fond of. I would imagine the frogs flat against the swinging mango leaves for the cold months, almost sealed to the leaf, everything tucked in to reduce moisture loss, probably dreaming frog dreams of the coming rains.
If the rain persisted, after several days a huge chorus of wailing frogs would drift up from a creek a hundred metres down the road. It was the largest chorus I’d heard of frogs in my suburb, and after the rain ceased the calls would go all night, an eerie but somehow calming background soundtrack to a summer night. I’d sneak down there at night with a torch and a camera, to the vacant block between houses, and see stacks of these stunning emerald amphibians lining the edges of the creek calling. They’d probably been doing this there for many decades or probably centuries.
Sadly, I was there when this summer gathering ceased for good, as the block was developed for houses, the old paper-barks trashed and the creek lined with pipes and concrete. The red-bellied black snakes and the frogs all moved out or were killed. Progress always has its quiet, usually-unnoticed down-sides in a city like Brisbane, where the landscape is gradually changed and the many small creatures vanish as their habitat suffers the death of a thousand cuts. It was a sadder summer season there without the nightly chorus of these graceful frogs.
Really beautiful photographs of these superb frogs. I remember finding an orange tree with little green frogs on every second leaf when I was at primary school. They looked very similar to these. Don't we pay the price for progress?
Thanks, Russell. Yes, they are sublime little critters.
The amphibians always seem to be the first to go. We have some American Toads that live in our yard, and my place of work added a man-made wetland where there are Green Frogs. Is Australia experiencing sharp declines in frog populations like we are in the States?
Hey mate, like your blog! Wisconsin sounds like a great part of the world. Yes, we have experienced frog extinctions and declines, now thought to be due to a fungus introduced with the aquarium trade years ago, very worrying. The most well reported case was the disappearance of the gastric-brooding frog, which swallows its tadpoles and raise them in its stomach (http://www.derm.qld.gov.au/wildlife-ecosystems/wildlife/threatened_plants_and_animals/endangered/southern_gastricbrooding_frog.html).
