With luck
About 10% of wildlife watchers report an Australasian Grebe sighting in Blue Mountains National Park on a given day, based on 470 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 196 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report an Australasian Grebe in Blue Mountains National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Australasian Grebe sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 17
Of the 17 parks where we can rate Australasian Grebe sightings, Blue Mountains National Park ranks 6th at about 10%. The best odds are in Uluru-Kata Tjuta National Park (Australia, about 20%), Hattah-Kulkyne National Park (Australia, about 10%) and Royal National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Australasian Grebe is recorded against all the birds logged in Blue Mountains National Park (470 verified sightings from 2019 to 2026), 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.
