Rare
Under 5% of wildlife watchers report a White-banded Mockingbird sighting in Iberá National Park on a given day, based on 58 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 284 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 to September
In those months about 10% of wildlife watchers report a White-banded Mockingbird in Iberá National Park on a given day, against under 5% in October to April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-banded Mockingbird sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate White-banded Mockingbird sightings, Iberá National Park ranks 3rd at under 5%. The best odds are in El Impenetrable National Park (Argentina, about 20%) and Península Valdés (Argentina, about 10%).
GBIF citizen-science records
It is estimated from how often the White-banded Mockingbird is recorded against all the birds logged in Iberá National Park (58 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.
