Possible
About 20% of wildlife watchers report a Pale Sand Martin sighting in Jinhua on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 39th most-seen of the 74 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Pale Sand Martin in Jinhua on a given day, against about 10% in April, June and August–October, the lowest months. That is one of Jinhua's driest months, with about 65 mm of rain against 300 mm in June. January–March and July have too few records to rate.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pale Sand Martin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Pale Sand Martin sightings, Jinhua has the highest daily chance: about 20%. Next come Chongqing (China, about 10%) and Chengdu (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Pale Sand Martin is recorded against all the birds logged in Jinhua (9 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.
