Measuring 20 cm (7.9 in) long, this highly social species is entirely black, save for the namesake brown-orange patch at the shoulder. The patch may not be visible when the wings are folded.[2]

- A. h. humeralis – (Vigors, 1827): nominate, found in Cuba and Hispaniola
- A. h. scopulus – Garrido, 1970: found on Cayo Cantiles (east of Isla de la Juventud off southwestern Cuba)
Breeding
They breed from April to August, laying 3–4 greenish-white eggs spotted with brown in a cup-shaped nest that is lined with soft materials and placed in a tree.[2]
Diet and habitat
Tawny-shouldered blackbirds eat insects, seeds, nectar, fruit, and small lizards.[2] Its natural habitats are subtropical or tropical dry shrubland, pastureland, and heavily degraded former forest.
