Adult. Remarks: Some images of the Golden-bellied Gerygone host parents to a juvenile Little Bronze Cuckoo. Note a feature that I have not seen described in literature - the symmetrical brown curved lines that come from the base of the neck into the breast but do not meet. This feature can be seen in OBI images especially of the G. s. sulphurea subspecies. Some birds (on-line image search) have it very prominently, others less obvious. I wonder if it is a breeding plumage and waxes-wanes? -Amar. Date added to OBI: December 05, 2018.
