Introduction

Familiar to virtually every Cuban, who know it as the Totí, the Cuban Blackbird is found throughout the main island of Cuba, where it is virtually universally common, but is absent from the Isle of Youth and any of the many offshore cays. The Cuban Blackbird is entirely black, albeit with a violaceous metallic sheen to the upperparts, and females are marginally duller than males. It is most likely to be confused with the almost equally ubiquitous resident Greater Antillean Grackle (Quiscalus niger), but the latter species has yellow irides, a longer and narrower bill, and a keel-shaped tail, which is especially obvious in flight or on the ground. The Cuban Blackbird is found in virtually any type of wooded habitat, including gardens in cities, and like most resident species on the island nests in March to July.

Field Identification

25–28 cm; male 85–94 g, female 72–80 g. Medium-sized icterid with square-shaped tail and relatively short bill. Plumage is black overall, with strong blue and purple iridescence on body, and greenish-blue gloss on wing (plumage reflects ultraviolet in several patches); iris dark brown; bill and legs black. Distinguished from similar male Molothrus bona­riensis mainly by much larger size. Sexes similar, female slightly duller than male. Juvenile is like adult but much duller, brownish-black without gloss.

Systematics History

Curiously absent from I of Pines (old reports erroneous) suggesting poor dispersal capabilities. Monotypic.

Subspecies

Monotypic.

Distribution

Cuba.

Habitat

Open woodlands, agricultural land, parks, gardens, urban parks, villages. Lowlands to medium elevations.

Movement

Resident.

Diet and Foraging

Almost omnivorous; feeds on arthropods, small vertebrates, seeds, fruits and nectar. Forages mostly on ground; sometimes follows grazing cattle. Found in pairs and in small flocks; sometimes joins other icterids, such as Quiscalus niger or Agelaius humeralis, particularly at roosts.

Sounds and Vocal Behavior

Song varied, probably by both sexes, a mix of musical notes and some nasal sounds. Musical “twee-o” and “twee-te-to” calls.

Breeding

Season Apr–Jul; fledglings reported May–Aug. Probably monogamous, but no details available. Solitary nester. Nest built by both sexes, cup-shaped, made variously from fig (Ficus) rootlets, hair and feathers, lined with finer material (e.g. fibres from a species of Araceae), one had external diameter 17·5 cm and internal diameter 8·5 cm, depth 3 cm, placed in enclosed space such as base of palm frond, often of Cuban royal palm (Roystonea regia), sometimes in coconut (Cocos nucifera) or other unidentified palm, or in clump of epiphytic bromeliads, or in open cavity in dead tree; sometimes in building, e.g. three nests built on beam below roof of a sentry box, and one nest found 2·8 m up inside building near Havana. Clutch 3–4 eggs, greyish-white with dark brown spots, mostly at large end, mean dimensions c. 29 × 19 mm; estimated incubation period 12 days; chicks fed by both parents, no information on duration of nestling period.
Not globally threatened. Common, and widespread. A rather abundant species that tolerates habitat modification, living and breeding even in towns and cities. Confined to mainland Cuba, and absent from cays and outlying islands; reports of this species from I of Pines erroneous, apparently referable to misidentified Quiscalus niger. No known threats, and not reported as a Molothrus bonariensis host.

Abundance

Relative abundance is depicted for each season along a color gradient from a light color indicating lower relative abundance to a dark color indicating a higher relative abundance. Relative abundance is the estimated average count of individuals detected by an eBirder during a 1 hour, 1 kilometer traveling checklist at the optimal time of day for each species.   Learn more about this data
