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.
The Horsfield's bronze cuckoo is one of five Australian species in the genus Chalcites (formerly Chrysococcyx) a type of parasitic bird, that parasitizes fairy-wrens primarily to raise their young. The main diet of the Horsfield's bronze cuckoo is insects and they are nomadic, travelling to different regions of Australia to breed and find food. 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.
The Horsfield's bronze cuckoo is known as a brood parasite, this means that they lay their eggs in a host species... Wikipedia →

Rare
Under 5% of wildlife watchers report a Horsfield's Bronze Cuckoo sighting in Sydney on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 176th most-seen of the 243 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 Sydney on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Horsfield's Bronze Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Horsfield's Bronze Cuckoo sightings, Sydney ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Melbourne (Australia, under 5%), Brisbane (Australia, under 5%) and Jakarta (Indonesia, under 5%).
GBIF citizen-science records
It is estimated from how often the Horsfield's Bronze Cuckoo is recorded against all the birds logged in Sydney (40 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.
