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.

Rare
Under 5% of wildlife watchers report a White-eyed Vireo sighting in Monterrey on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 105th most-seen of the 207 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.
March and December
In those months about 10% of wildlife watchers report a White-eyed Vireo in Monterrey on a given day, against under 5% in January–February and April–November, the lowest months. Those are among Monterrey's driest months, with about 25 mm of rain a month against 200 mm in September.
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.
8th of 20
Of the 20 cities where we can rate White-eyed Vireo sightings, Monterrey ranks 8th at under 5%. The best odds are in Austin (United States, about 30%), San Antonio (United States, about 30%) and Dallas (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the White-eyed Vireo is recorded against all the birds logged in Monterrey (39 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.
