Possible
About 30% of wildlife watchers report a South Island Pied Oystercatcher sighting in Auckland on a given day, based on 1,684 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 93 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 40% of wildlife watchers report a South Island Pied Oystercatcher in Auckland on a given day, against about 20% in April and September–October, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most South Island Pied Oystercatcher sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate South Island Pied Oystercatcher sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the South Island Pied Oystercatcher is recorded against all the birds logged in Auckland (1,684 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.
