Rare
Under 5% of wildlife watchers report a Black-striped Sparrow sighting in Machalilla National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and November–December
In those months about 10% of wildlife watchers report a Black-striped Sparrow in Machalilla National Park on a given day, against under 5% in January–April and June–October, the lowest months. Those are among Machalilla National Park's driest months, with about 25 mm of rain a month against 140 mm in February.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Black-striped Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 26
Of the 26 parks where we can rate Black-striped Sparrow sightings, Machalilla National Park ranks 18th at under 5%. The best odds are in Piedras Blancas National Park (Costa Rica, about 50%), Arenal Volcano National Park (Costa Rica, about 40%) and Chagres National Park (Panama, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black-striped Sparrow is recorded against all the birds logged in Machalilla National Park (22 verified sightings from 2019 to 2026), 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.
