Possible
About 30% of wildlife watchers report a Western Striped Albatross sighting in Đà Nẵng on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 9 insects 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.
December
In that month about 50% of wildlife watchers report a Western Striped Albatross in Đà Nẵng on a given day, against under 5% in January–March and June–July, the lowest months.

Of the 32 cities where we can rate Western Striped Albatross sightings, Đà Nẵng ranks 11th at about 30%. The best odds are in Cần Thơ (Vietnam, about 50%), Yogyakarta (Indonesia, about 40%) and Davao City (Philippines, about 30%).
GBIF citizen-science records
It is estimated from how often the Western Striped Albatross is recorded against all the insects logged in Đà Nẵng (5 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.
