The tawny-shouldered blackbird (Agelaius humeralis) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Cuba and Haiti and possibly the Dominican Republic. It is also a vagrant to the Florida Keys in the United States.
The tawny-shouldered blackbird was formally described in 1827 with the binomial Leistes humeralis. It and the yellow-shouldered blackbird (A. xanthomus) are sister species and form a superspecies. It is known in Cuba as "mayito" and in Haiti as "ti kawouj".
The tawny-shouldered blackbird is 19 to 22 cm (7.5 to 8.7 in) long. Males weigh an average of 38.3 g (1.4 oz) and females an average of 34.5 g (1.2 oz). Adult males of the nominate subspecies are mostly black with a slight bluish gloss. Their lesser and median upperwing coverts are tawny and the median coverts have yellowish cream tips. Adult females are duskier than males and lack the bluish gloss. They have a smaller amount of tawny on the coverts and the median coverts... Wikipedia →

Possible
About 20% of wildlife watchers report a Tawny-shouldered Blackbird sighting in Havana on a given day, based on 344 verified sightings from GBIF citizen-science data. It is the 37th most-seen of the 183 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Tawny-shouldered Blackbird in Havana on a given day, against under 5% in January, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Tawny-shouldered Blackbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Havana, in our data
Havana is the only city on Wallace's Line with enough records to rate Tawny-shouldered Blackbird sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Icteridae
The closest relatives of the Tawny-shouldered Blackbird that you can see in Havana (family Icteridae, New World Blackbirds and Orioles) are Cuban Blackbird (about 70%), Greater Antillean Grackle (about 50%) and Eastern Meadowlark (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tawny-shouldered Blackbird is recorded against all the birds logged in Havana (344 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.
