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 →

Likely
About 50% of wildlife watchers report a Tawny-shouldered Blackbird sighting in Ciénaga de Zapata on a given day, based on 853 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 177 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.
July
In that month about 70% of wildlife watchers report a Tawny-shouldered Blackbird in Ciénaga de Zapata on a given day, against about 30% in October, the lowest month. September has too few records to rate.

Only Ciénaga de Zapata, in our data
Ciénaga de Zapata is the only park on Wallace's Line with enough records to rate Tawny-shouldered Blackbird sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Tawny-shouldered Blackbird is recorded against all the birds logged in Ciénaga de Zapata (853 verified sightings from 2019 to 2026), 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.
