Rare
Under 5% of wildlife watchers report an Eastern Spinebill sighting in Brisbane on a given day, based on 74 verified sightings from GBIF citizen-science data. It is the 181st most-seen of the 237 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 an Eastern Spinebill in Brisbane on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Eastern Spinebill sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Eastern Spinebill sightings, Brisbane ranks 4th at under 5%. The best odds are in Hobart (Australia, about 20%), Melbourne (Australia, about 10%) and Sydney (Australia, about 10%).
Same family: Meliphagidae
The closest relatives of the Eastern Spinebill that you can see in Brisbane (family Meliphagidae, Honeyeaters) are Noisy Miner (about 90%), Brown Honeyeater (about 50%) and Blue-faced Honeyeater (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Spinebill is recorded against all the birds logged in Brisbane (74 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.
