The swamp sparrow (Melospiza georgiana) is a medium-sized New World sparrow related to the song sparrow. Measurements: Length: 4.7–5.9 in (12–15 cm) Weight: 0.5–0.8 oz (15–23 g) Wingspan: 7.1–7.5 in (18–19 cm) Adults have streaked rusty, buff and black upperparts with an unstreaked gray breast, light belly and a white throat. The wings are strikingly rusty. Most males and a few females have rust-colored caps. Their face is gray with a dark line through the eye. They have a short bill and fairly long legs. Immature birds and winter adults usually have two brown crown stripes and much of the gray is replaced with buff.

A small number of morphologically distinct birds inhabit tidal marshes from northern Virginia to the Hudson River Estuary. This subspecies (M. g. nigrescens) winters in coastal marshes of the Carolinas and differs from the two inland swamp sparrow subspecies in having more black in a grayer overall plumage, larger bill, different songs, and a smaller average...

Rare
Under 5% of wildlife watchers report a Swamp Sparrow sighting in Miami on a given day, based on 74 verified sightings from GBIF citizen-science data. It is the 233rd most-seen of the 325 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 Swamp Sparrow in Miami on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Swamp Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
23rd of 28
Of the 28 cities where we can rate Swamp Sparrow sightings, Miami ranks 23rd at under 5%. The best odds are in New York City (United States, about 20%), Baltimore (United States, about 10%) and Chicago (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Swamp Sparrow is recorded against all the birds logged in Miami (74 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.
