The mourning warbler (Geothlypis philadelphia) is a small songbird of the New World warbler family. Mourning warblers are neotropical migrants native to eastern and central North America and wintering in Central and South America. They tend to be found in dense second growth forests. They are very similar to the MacGillivray's warbler in appearance, especially in females and immature birds, but their breeding range does not overlap into the west.
The "mourning" in this bird's name refers to the male's hood, thought to resemble a mourning veil. Mourning warblers are small songbird with yellow underparts, olive-green upperparts, a thin pointed bill and pink legs. Adult males have a gray hood, black lores and a black patch on the throat and breast. In the fall, this pattern becomes less bright and harder to distinguish from similar species; however they never have a broken eye ring. Females and immatures are gray-brown on the head with an incomplete eye-ring. They have a yellow-gray throat with a brown or olive tint to their breast. Both sexes can range from 10 to 15 cm (3.9–5.9 in) in length and 11–13 g (0.4–0.5 oz) in weight. Their wingspan is 18 cm (7.1 in). Other... Wikipedia →

Rare
Under 5% of wildlife watchers report a Mourning Warbler sighting in Henri Pittier National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 333rd most-seen of the 358 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 Mourning Warbler in Henri Pittier National Park on a given day, against under 5% in November to September, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Mourning Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
24th of 39
Of the 39 parks where we can rate Mourning Warbler sightings, Henri Pittier National Park ranks 24th at under 5%. The best odds are in Gros Morne National Park (Canada, about 30%), Riding Mountain National Park (Canada, about 20%) and Cape Breton Highlands National Park (Canada, about 10%).

GBIF citizen-science records
It is estimated from how often the Mourning Warbler is recorded against all the birds logged in Henri Pittier National Park (6 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.
