Yesterday, after persuading my mother, she finally brought me to Sime Forest. We started off at Macritchie Reservoir park. Once I entered the forest, I saw what I thought was a greater goldenback.
It may have been a common goldenback-https://birdsrule.wordpress.com/2007/11/07/common-flameback/

I thought it might be a Greater goldenback because of its eyes. The eye is white with a black dot in it.
