Possible
About 20% of wildlife watchers report a Variable Seedeater sighting in Guayaquil on a given day, based on 209 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 167 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.
April
In that month about 40% of wildlife watchers report a Variable Seedeater in Guayaquil on a given day, against about 10% in October, the lowest month. That is one of Guayaquil's wettest months, with about 130 mm of rain against almost none in September.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Variable Seedeater sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 4
Of the 4 cities where we can rate Variable Seedeater sightings, Guayaquil ranks 2nd at about 20%. The best odds are in Panama City (Panama, about 30%).
GBIF citizen-science records
It is estimated from how often the Variable Seedeater is recorded against all the birds logged in Guayaquil (209 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.
