How to Identify a Singing Starling
The Singing Starling is a medium-sized bird with a length of approximately 24 centimeters. Its plumage is glossy black, exhibiting a striking iridescence that can range from blue to green, depending on the angle of light. Adults possess a slender, slightly curved bill and a long tail, which aids in their distinctive flight patterns. Juveniles are similar in appearance but may exhibit duller plumage with less iridescence and a brownish tinge, particularly around the face and underparts.
While both male and female Singing Starlings display similar plumage, slight differences can be noted during the breeding season. Males may exhibit a slightly more pronounced iridescence and a brighter sheen, likely as a result of increased preening and grooming during courtship displays. In flight, the Singing Starling's silhouette is characterized by its broad wings and long, slightly forked tail, allowing for agile maneuvers through the canopy and open spaces.
The Singing Starling can be confused with other members of the Sturnidae family, particularly the Metallic Starling. However, the latter typically displays a more pronounced green sheen and red eyes. Observing the Singing Starling perched, its upright posture and frequent vocalizations are key identifiers, as the bird often emits a variety of melodic calls while resting in treetops or other elevated perches.

What Does the Singing Starling Eat?
The diet of the Singing Starling is primarily frugivorous, consisting largely of fruits and berries. Common food sources include figs, bananas, and various native fruits, which provide the necessary nutrients for energy and reproduction. During the breeding season, when nutritional demands increase, the bird may consume larger quantities of fruit to sustain itself and its offspring.
In addition to fruits, the Singing Starling also forages for insects and other small invertebrates, particularly during periods when fruit is less abundant. This opportunistic feeding strategy aids in pest control and allows the bird to maintain a balanced diet. Foraging typically occurs in the morning and late afternoon, with the starling either searching through foliage or catching insects in flight.
The bird's feeding technique is characterized by agility and precision, often plucking fruit with its bill or gleaning insects from leaves and branches. The size of prey and fruit varies, but the Singing Starling generally targets items it can easily handle and digest, ensuring efficient energy intake.
Singing Starling Behavior and Social Structure
Social by nature, the Singing Starling often forms loose flocks outside the breeding season, allowing for cooperative foraging and enhanced predator detection. During the breeding season, however, the bird becomes more territorial, with males establishing and defending territories through vocal displays and physical presence.
Courtship displays are a prominent feature of the Singing Starling's behavior. Males sing complex songs, incorporating a range of whistles, trills, and mimicry to attract females and deter rivals. These displays often occur from prominent perches, such as tree tops or utility wires, where the male can be easily seen and heard.
The Singing Starling is diurnal, with peak activity periods in the morning and late afternoon. This scheduling aligns with optimal foraging times, allowing the bird to exploit food resources efficiently.
