One species that attracts a lot of birders to this area in South Australia is the elusive Slender-billed Thornbill. I love this bird, not only because it is a gorgeous little feather ball but also because it can be a bugger to photograph! They like hiding in the marsh and often remain concealed even when calling. I think the main secret in getting good views of these little bundles is patience. If at first you don't succeed, try, try again - and WAIT! Stay there, eat your lunch there, stay still and quiet and LISTEN for them!
I spent a few hours enjoying Port Gawler and Port Wakefield and came home with a few shots for my efforts.
