THEY’RE clicking and moaning down Bibra Lake way in Western Australia – the frogs, that is.

Clicking and moaning frogs, along with other species including motorbike and western banjo (also known as “pobblebonks”), were highlighted during a recent frog night stalk at the Cockburn Wetlands Education Centre.

Part of the City of Cockburn’s Get Wild About Wetlands program, about 40 nature enthusiasts had the chance to get up close and personal with friendly frogs common to Bibra Lake and other Beeliar wetlands.

City of Cockburn Environment and Education Officer Vicky Hartill said the moaning frog (Heleioporus eyrie), although quite common, was sometime difficult to find because it is a burrowing frog.

“They have almost finished their breeding season now, so we were quite lucky to find one close to the water’s edge,” she said.

“The male frogs burrow into the wetland sediment and call loudly with a ‘whooo… whooo’ or ‘moooaaa’ sound to the females to signal the breeding season.

“The call needs to be loud because the females are waiting upland in the eucalypt-banksia woodlands or melaleuca thickets.

“Upon first winter rains, the females move down into the wetland to join the males. Breeding takes place and the burrows fill with water, bringing the tadpoles to the surface.”

Ms Hartill said if people went down to the wetlands now they were more likely to hear the clicking or pobblebonk frogs.

“It was a highly successful night stalk with many people getting the chance to discover the diversity of frogs we have in the area,” she said.

All proceeds from the event have gone to further wetland conservation.
