The boat-tailed grackle (Quiscalus major) is a passerine bird of the family Icteridae found as a permanent resident on the coasts of the Southeastern and Mid-Atlantic United States. The boat-tailed grackle is found in coastal saltwater marshes and across the Florida peninsula. In salt marsh areas, least bitterns will often associate with and make mixed colonies with grackles. Boat-tailed grackles have established significant populations in several United States Gulf Coast cities and towns, using human activity as protection against predation and scavenging through human trash. Urban boat-tailed grackle populations can be found foraging in trash bins, parking lots, and outdoor restaurant patios.
The nest is a well-concealed cup in trees and shrubs near water; the average clutch size is just over three eggs. Male boat-tailed grackles compete to defend and mate with a harem of closely nesting females, although DNA evidence shows that females often successfully mate with other males while away from their colony, with only about a quarter of the young being fathered by the dominant male.
The male boat-tailed grackle is 37–43 cm (15–17 in) long... Wikipedia →

Likely
About 60% of wildlife watchers report a Boat-tailed Grackle sighting in Miami on a given day, based on 25,908 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 325 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Boat-tailed Grackle is recorded against all the birds logged in Miami (25,908 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.
