Rare
Under 5% of wildlife watchers report a Fluttering Shearwater sighting in Sydney on a given day, based on 74 verified sightings from GBIF citizen-science data. It is the 163rd 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 Fluttering Shearwater in Sydney on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Fluttering Shearwater 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 2 cities where we can rate Fluttering Shearwater sightings, Sydney ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Auckland (New Zealand, under 5%).
GBIF citizen-science records
It is estimated from how often the Fluttering Shearwater is recorded against all the birds logged in Sydney (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.
