The bobolink (Dolichonyx oryzivorus) is a small New World blackbird and the only member of the genus Dolichonyx. An old name for this species is the "rice bird", from its tendency to feed on cultivated grains during winter and migration. The bobolink breeds in the summer in the United States and Canada, with most of the summer range in the northern U.S. Bobolinks winter in southern South America, primarily Paraguay, Argentina, and Bolivia. Bobolink numbers are rapidly declining due to factors such as agricultural intensification and habitat loss; they are considered threatened in Canada, and are at risk throughout their range.
The bobolink was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with the finches in the genus Fringilla and coined the binomial name Fringilla oryzivora. Linnaeus mainly based his account on "The Rice-Bird" that had been described and illustrated in 1729 by the English naturalist Mark Catesby in his book The Natural History of Carolina, Florida and the Bahama Islands. Linnaeus specified the type locality as "Cuba... in Carolinam" but this was restricted to the state of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bobolink sighting in Celestún Biosphere Reserve on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 211th most-seen of the 297 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Bobolink in Celestún Biosphere Reserve on a given day, against under 5% in June to April, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Bobolink 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 16
Of the 16 parks where we can rate Bobolink sightings, Celestún Biosphere Reserve ranks 8th at under 5%. The best odds are in Isla del Coco National Park (Costa Rica, about 30%), Badlands National Park (United States, about 10%) and Point Pelee National Park (Canada, under 5%).
Same family: Icteridae
The closest relatives of the Bobolink that you can see in Celestún Biosphere Reserve (family Icteridae, New World Blackbirds and Orioles) are Great-tailed Grackle (about 60%), Hooded Oriole (about 40%) and Altamira Oriole (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bobolink is recorded against all the birds logged in Celestún Biosphere Reserve (30 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.
