The white-eyed vireo (Vireo griseus) is a small songbird of the family Vireonidae. It breeds in the eastern United States from New England west to northern Missouri and south to Texas and Florida, and also in eastern Mexico, northern Central America, Cuba and the Bahamas. Populations on the US Gulf Coast and further south are resident, but most North American birds migrate south in winter. This vireo frequents bushes and shrubs in abandoned cultivation or overgrown pastures.
They nest near the ground in tangled thickets. Nests are made of weeds, leaves, grass, bark or bits of trash. The grass-lined nest is a neat cup shape, attached to a fork in a tree branch by spider webs. It lays 3–5 dark-spotted white eggs. Both the male and female incubate the eggs for 12–16 days. The young leave the nest 9–11 days after hatching.

With luck
About 10% of wildlife watchers report a White-eyed Vireo sighting in Merritt Island National Wildlife Refuge on a given day, based on 1,283 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 84th most-seen of the 279 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a White-eyed Vireo in Merritt Island National Wildlife Refuge on a given day, against under 5% in July, the lowest month. That is one of Merritt Island National Wildlife Refuge's wettest months, with about 210 mm of rain against 50 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-eyed Vireo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 26
Of the 26 parks where we can rate White-eyed Vireo sightings, Merritt Island National Wildlife Refuge ranks 13th at about 10%. The best odds are in Congaree National Park (United States, about 50%), Everglades National Park (United States, about 50%) and Calakmul Biosphere Reserve (Mexico, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the White-eyed Vireo is recorded against all the birds logged in Merritt Island National Wildlife Refuge (1,283 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.
