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 Jakarta on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 111th most-seen of the 138 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Horsfield's Bronze Cuckoo in Jakarta on a given day, against under 5% in July to May, the lowest months. That is one of Jakarta's driest months, with about 90 mm of rain against 370 mm in February.
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, Jakarta ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Melbourne (Australia, under 5%) and Brisbane (Australia, under 5%).
Same family: Cuculidae
The closest relatives of the Horsfield's Bronze Cuckoo that you can see in Jakarta (family Cuculidae, Cuckoos) are Plaintive Cuckoo (about 20%), Cuculus nisicolor (about 10%) and Lesser Coucal (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Horsfield's Bronze Cuckoo is recorded against all the birds logged in Jakarta (17 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.
