Walka Lake is situated on the edge of the rural city of Maitland. A reservoir surrounded by parks and bushland, it is a haven for waterfowl and native birdlife, and this recording takes us through a day by its shoreline.
Throughout the night, a community of tiny Crinia froglets have been chorusing from reedbeds surrounding the lake. As the first light of dawn enters the sky, a pair of Black Swans bugle gently as they float on the still waters, the wings of waterfowl whistle overhead, and the calls of ducks echo off the treeline.
From surrounding bushland, the dawn chorus begins with kookaburras, magpies, honeyeaters, whistlers, robins and spinebills. As the morning warms up, flocks of silvereyes and yellow thornbills move through the tree canopy, while fantails flutter acrobatically and fairy-wrens trill from the undergrowth.
Meanwhile, coots dabbling near the shore occasionally erupt in an agitation of splashing and explosive calls. Ravens, lorikeets, galahs and black cockatoos can be heard occasionally as they wing over the lake, and a grey shrike thrush gives a virtuosic display of subsong nearby.
By late morning, a breeze has sprung up, stirring the foliage of the casuarinas lining the shore. At this point, we take a midday break, and listen instead to the life under the waters of the lake itself, a secret soundscape of tiny aquatic insects.
We return in the late afternoon, as birds give their last calls of the day. A white-faced heron calls wheezily as it flaps past, and as the light fades, the crinia froglets begin their nocturnal chorus. With dusk, everything settles down, except the coots, which indulge in a last flurry of commotion out on the still waters.
