The Connecticut warbler (Oporornis agilis) is a small songbird of the New World warbler family. These medium-sized warblers measure 13–15 cm (5.1–5.9 in) in length, with a 22–23 cm (8.7–9.1 in) wingspan. Connecticut warblers weigh 10 g (0.35 oz) when they fledge, attaining an average weight of around 15 g (0.53 oz) as adults. However, birds preparing for migration pack on more weight to survive the strenuous journey and can weigh up to 25 g (0.88 oz). This species has light yellow underparts and olive upperparts; they have a light eye-ring, pink legs, a long tail, and a thin pointed bill. Males have a grey hood; females and immatures are more brown and have a whitish throat.
They forage on the ground, picking among dead leaves, or hop along branches. Like most warblers, these birds mainly eat insects and similar small invertebrates. They will also supplement their diet occasionally with seeds and berries. They are "skulking" birds that usually spend their time foraging within dense, low vegetation. Such behavior often renders them difficult to see well.
Despite its name, this bird only rarely visits Connecticut during migration. It was named by Alexander Wilson who... Wikipedia →

Rare
Under 5% of wildlife watchers report a Connecticut Warbler sighting in Miami on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 256th 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 Connecticut Warbler 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 Connecticut Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 cities where we can rate Connecticut Warbler sightings, Miami ranks 8th at under 5%, level with the leaders once rounded. The best odds are in Chicago (United States, under 5%), Baltimore (United States, under 5%) and Toronto (Canada, under 5%).
Same family: Parulidae
The closest relatives of the Connecticut Warbler that you can see in Miami (family Parulidae, New World Warblers) are Palm Warbler (about 50%), Black-and-white Warbler (about 30%) and Northern Parula (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Connecticut Warbler is recorded against all the birds logged in Miami (53 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.
