Horsfield's bronze cuckoo (Chalcites basalis) is a small cuckoo in the family Cuculidae. Its size averages 22 g (0.78 oz) and is distinguished by its green and bronze iridescent colouring on its back and incomplete brown barring from neck to tail. Horsfield's bronze cuckoo can be distinguished from other bronze cuckoos by its white eyebrow and brown eye stripe. The Horsfield's bronze cuckoo is common throughout Australia preferring the drier open woodlands away from forested areas. This species was formerly placed in the genus Chrysococcyx.

Small insects are taken from leaves, branches, caught on the wing and in breeding season, Horsfield's bronze cuckoos feed each other in a courtship ritual.

It is the 132nd most-seen of the 162 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Horsfield's Bronze Cuckoo in Perth on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Horsfield's Bronze Cuckoo is recorded against all the birds logged in Perth (21 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
