This species of parrot exhibits unique locomotion, self-maintenance, agonistic, sexual behavior and has an interesting breeding pattern. Here, we will explore these behaviors and the relevant implications of their behavior patterns on the bird’s populations.

Behavior:

Locomotion:

Black-winged Lories move through their habitat mainly by flying, but they can also climb trees and hop from one branch to another. During flight, their wings make a whistling sound, making it easier to identify them even from a distance.

Self Maintenance:

To maintain healthy plumage, Black-winged Lories preen their feathers regularly, dust their plumage, and take frequent baths. The bird bathes in shallow pools of water, usually in small streams that flow through their habitats.

This self-maintenance helps keep their feathers in top condition, improve their sexual behavior quality, as well as protect against parasite infestation. Agonistic Behavior:

Like many parrot species, the Black-winged Lory exhibits agonistic behaviors such as displaying aggressive vocal behavior, aggressive wing flapping, and forcefully lunging at perceived threats.

These behaviors usually manifest when their territories or chosen nest sites are intruded upon. These behaviors are most common during the breeding season and are essential to protect their young.

Sexual Behavior:

During breeding season, males vocalize and display a number of behaviors, including wing flapping, tail wagging, and extended neck movements to attract females. Both males and females will frequently visit potential nest sites, and both take part in the building of the nest.

The courtship is often marked with frequent and playful flights together. Breeding:

Black-winged Lories breed seasonally, typically between October and February.

During breeding season, the birds display a range of behaviors to attract mates and establish territories. Interestingly, the bird may nest communally whereby multiple birds nest together in the same trees, sometimes even sharing a feeding site.

The birds typically construct a rough and shallow cup-shaped nest in natural tree hollows, using sticks, leaves, and twigs, cemented with either saliva or poorly digested plant material. They lay a clutch of two eggs, which the female incubates over a period of 23-25 days.

Both parents take turns incubating the eggs and feeding the young chicks until they are independent enough to fend for themselves.

Demography and Populations:

The Black-winged Lory has a relatively small population, and the numbers are still decreasing due to habitat loss and other human activities, such as illegal trade.

Despite being protected in some areas, the bird now has a red-listed endangered status. Development of human settlements, overgrazing and felling of trees, climate change, and other factors have diminished the bird’s population in the wild, thereby making it increasingly vulnerable and threatened.
