Musophaga rossae Gould, 1852

Scientific Name and Common Name

Musophaga rossae (commonly known as Ross's turaco) shows very little sexual dimorphism: both males and females have the same deep blue plumage, along with red crowns and red flight feathers.

Sexual Dimorphism

Female beaks are often slightly more yellow-green, while male beaks are always bright yellow; both sexes have a forehead shield that flares to a medium orange.

Wing Structure

This species has short, round wings, suited for short bursts of powered flight.

Limb and Toe Adaptations

Their legs are black, with three toes facing forward and a fourth semi-zygodactylous toe, an adaptation that makes them nimble canopy dwellers.

Size and Weight

Adult individuals range from 15 to 18 inches in length and weigh just under one pound.

Lifespan

Ross's turaco are sturdy birds, with reported lifespans ranging from 8 to 20 years across different sources.

Habitat Range

This species is primarily found in woodlands, open forest, and riparian habitats across Angola, Botswana, Burundi, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Gabon, Kenya, Rwanda, South Sudan, Tanzania, Uganda, and Zambia.

Habitat Preferences

They generally avoid densely forested areas.

Movement Patterns

They are non-migratory and rarely travel far from their birthplace, though they will move if food is scarce in their local area.

Conservation Status

Despite threats from agricultural expansion causing habitat destruction, their population remains stable.

Breeding Pair Behavior

Ross's turaco form monogamous breeding pairs that share incubation and feeding responsibilities.

Egg and Incubation Details

Pairs lay 2 to 3 eggs, which hatch after approximately 25 days of incubation.

Nestling Period

Young birds spend another 4 to 7 weeks in the nest with their parents before fledging.

Juvenile Behavior

Unusually, young Ross's turaco become mostly independent before they are able to fly, and instead climb through the forest canopy.

Sexual Maturity and Social Structure

They reach sexual maturity at one year of age, and typically stay near their parents in extended family flocks that can number up to thirty individuals.

Cooperative Breeding

Flock members often help raise other flock members' chicks, particularly when the mother is breeding for the first time.

Territorial Behavior

This species becomes more territorial during the brooding season, especially toward predatory or unfamiliar birds.
