The dark-eyed junco was formally described by the Swedish naturalist Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Fringilla hyemalis. The description consisted merely of the laconic remark "F[ringilla] nigra, ventre albo. ("A black 'finch' with white belly") and a statement that it came from America. Linnaeus based his description on the "Snow-Bird" that Mark Catesby had described and illustrated in his 1731 The Natural History of Carolina, Florida and the Bahama Islands.
The Bill of this Bird is white: The Breast and Belly white. All the rest of the Body dark grey; but in some places black, inclining to Lead-color. In Virginia and Carolina they appear only in Winter: and in Snow they appear most. In Summer none are seen. Whether they retire and breed in the North (which is most probable) or where they...

Rare
Under 5% of wildlife watchers report a Dark-eyed Junco sighting in Houston on a given day, based on 157 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 302 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dark-eyed Junco in Houston on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Dark-eyed Junco sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
30th of 30
Of the 30 cities where we can rate Dark-eyed Junco sightings, Houston ranks 30th at under 5%. The best odds are in Seattle (United States, about 80%), Portland (United States, about 70%) and Vancouver (Canada, about 50%).
Same family: Passerellidae
The closest relatives of the Dark-eyed Junco that you can see in Houston (family Passerellidae, New World Sparrows) are White-throated Sparrow (about 10%) and Swamp Sparrow (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dark-eyed Junco is recorded against all the birds logged in Houston (157 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.
