The field sparrow (Spizella pusilla) is a small New World sparrow in the family Passerellidae. It is about 140 mm (6 in) long and weighs about 12.5 g (0.4 oz). The head is grey with a rust-coloured crown, white eye-ring and pink bill. The upper parts are brown streaked with black and buff, the breast is buff, the belly is white and the tail is forked. There are two different colour morphs, one being greyer and the other more rufous.
The field sparrow is distributed across eastern Canada and the eastern United States, with northern populations migrating southwards to southern United States and north-eastern Mexico in the fall. The typical habitat of this bird is bushy country with shrubs and grassland. The nest is a cup-shaped construction built on the ground and hidden beneath a bush or clump of grass. The birds forage on the ground or in low vegetation, feeding mainly on seeds and insects. The population is thought to be in slow decline, but it is a common species with a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

Rare
Under 5% of wildlife watchers report a Field Sparrow sighting in Detroit on a given day, based on 117 verified sightings from GBIF citizen-science data. It is the 124th most-seen of the 199 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Field Sparrow in Detroit 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 Field Sparrow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 16
Of the 16 cities where we can rate Field Sparrow sightings, Detroit ranks 12th at under 5%. The best odds are in Philadelphia (United States, about 10%), Baltimore (United States, about 10%) and Chicago (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Field Sparrow is recorded against all the birds logged in Detroit (117 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.
