This bird is tiny and jumps around the foliage and treetops in my garden. It constantly sings a melodious, varied and very sweet song. It took me a long time to get any pictures of it, and I thought it was a Weebill but now something about the beak shape makes me second guess that.
Have i come across a lonesome Brown Thornbill??
Geog: western district of victoria
Bill shape is Thornbill.
The yellow colouring of second and third photo suggest Yellow Thornbill as does the musical call.
The first looks like a juvenile striated.
