Swainson's warbler (Limnothlypis swainsonii) is a small species of New World warbler. It is monotypic, the only member of the genus Limnothlypis. Swainson's warbler was named after William Swainson, an English ornithologist.
Swainson's warblers are a small and rather undistinguished songbird, though they are fairly large for a New World warbler. Adults grow to 12.5–16 cm (4.9–6.3 in) in length and 11–20.5 g (0.39–0.72 oz) in weight. The wingspan averages 23 cm (9.1 in). They are a plain olive-brown above and pale yellow-white below. They have a whitish eyebrow stripe that runs above their eye, and the top of their head is a rusty brown. Unlike most other New World warblers that are mostly dimorphic, there is no difference in appearance between a male or female Swainson's warbler.
Swainson's warblers are uncommon, mostly found in flooded swamplands and canebrakes of the south-eastern United States. More rarely, they will also occur in rhododendron thickets in the southern Appalachian Mountains. They are a migratory species, with part of the population migrating southeastwards to the Greater Antilles (where it overwinters in the Blue Mountains... Wikipedia →

Rare
Under 5% of wildlife watchers report a Swainson's Warbler sighting in Tikal National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 224th most-seen of the 300 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.
October
In that month about 10% of wildlife watchers report a Swainson's Warbler in Tikal National Park on a given day, against under 5% in November to September, the lowest months. That is one of Tikal National Park's wettest months, with about 190 mm of rain against 30 mm in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Swainson's Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 11
Of the 11 parks where we can rate Swainson's Warbler sightings, Tikal National Park ranks 6th at under 5%. The best odds are in Arrecifes de Cozumel National Park (Mexico, about 10%), Great Smoky Mountains National Park (United States, about 10%) and Blue and John Crow Mountains National Park (Jamaica, about 10%).
Same family: Parulidae
The closest relatives of the Swainson's Warbler that you can see in Tikal National Park (family Parulidae, New World Warblers) are Magnolia Warbler (about 60%), Black-and-white Warbler (about 50%) and Kentucky Warbler (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swainson's Warbler is recorded against all the birds logged in Tikal National Park (27 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.
