Which bird of the family "Pardalotidae" is in the picture?

The spotted pardalote ("Pardalotus punctatus") is a small passerine bird native to eastern and southern Australia, at elevations of up to 2,000 metres (6,600 ft). It is part of the pardalote family, "Pardalotidae".

One of the smallest of all Australian birds at 8 to 10 centimetres (3.1 to 3.9 in) in length, and one of the most colourful; it is sometimes known as the diamondbird. Although moderately common in all of the reasonably fertile parts of Australia (the east coast, the south-east, and the south-west corner) it is seldom seen closely enough to enable identification.

Spotted pardalotes breed between August or September to December or January—generally earlier in the year in northern parts of their range and later in southern areas. The nest is an underground horizontal oval chamber lined with shredded bark, linked by a tunnel 0.5 to 1.5 metres (1 ft 8 in to 4 ft 11 in) long to a hole in the side of a riverbank or slope in a shaded location.

The chamber is generally higher than the entrance tunnel, presumably to avoid flooding. Birds have used carpet rolls and garage roll-a-doors to nest in on occasion. Pairs breed once a year, producing a clutch of 3 to 4 round shiny white eggs 16 mm (0.63 in) long by 13 mm (0.51 in) wide. The eggs are incubated for 19 days until they hatch, with nestlings spending another 21 days in the nest.
