The blue-gray gnatcatcher (Polioptila caerulea) is a very small gnatcatcher native to North America.

With luck
About 10% of wildlife watchers report a Blue-gray Gnatcatcher sighting in Saguaro National Park on a given day, based on 418 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 67th most-seen of the 220 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
August–September and November–March
In those months about 10% of wildlife watchers report a Blue-gray Gnatcatcher in Saguaro National Park on a given day, against under 5% in April–July and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blue-gray Gnatcatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
29th of 40
Of the 40 parks where we can rate Blue-gray Gnatcatcher sightings, Saguaro National Park ranks 29th at about 10%. The best odds are in Arrecifes de Cozumel National Park (Mexico, about 70%), Big Cypress National Preserve (United States, about 60%) and Point Pelee National Park (Canada, about 60%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Blue-gray Gnatcatcher is recorded against all the birds logged in Saguaro National Park (418 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.
