Feeding

The Blue-rumped Pitta is mainly an insectivore species, foraging for small invertebrates such as worms, spiders, and insects. They have a highly specialized bill, which helps them to catch and eat insects efficiently.

Invertebrates are not the only option in their diet, and they may also eat small lizards, geckos, and other small vertebrates. In the forest, Blue-rumped Pittas display behavior known as “sit-and-wait,” where they remain stationary to wait for prey to come by.

They then quickly dart forward to secure the prey and retreat back to their original location.

Diet

Their diet differs according to their preferred habitat location. For birds in agroforestry systems, they have been observed eating ants and other small invertebrates encountered in the fields.

In secondary forests, their diet includes worms, beetles, moths and other insects. In lowland primary forests, their diet includes grasshoppers, ants, termites, beetles, moths, and spiders.

Forbs and seeds could occasionally be found in their diet too.

Metabolism and Temperature Regulation

The Blue-rumped Pitta is an endothermic bird, which means that it regulates its body temperature internally. Endothermic animals, also known as homeothermic animals, have to consume more energy than ectothermic animals since they have to maintain their temperature through metabolism.

Birds in general, including Blue-rumped Pittas, have high metabolic rates and consume substantial amounts of food daily. They have complex respiratory and circulatory systems that facilitate their rapid metabolism.

Sounds and Vocal Behavior

Vocalization

The Blue-rumped Pitta is a vocal species, and they use their calls for territorial displays, mating, and identifying themselves to other blue-rumped pittas. Males have a distinctive voice, and they have a larger vocal repertoire than females.

Their calls have been described as loud and brilliant, with piercing whistles and sharp notes. Bird watchers studying Blue-rumped Pittas in the wild have described their calls as “kleeup,” “klew-kliew”, and “poo-ee-ooo.” Calls are often slow and deliberate, followed by rapid and exuberant whistles, which end in a rolling trill.

Their calls are very distinct and sharp, and the pitch varies depending on the situation. Males use their vocalization during territorial disputes to create boundaries separating the territories.

They use their vocalization in a coordinated fashion, with each male taking turns in defending their territory vocally. Females also use their calls during breeding seasons to identify themselves to males.

Females are relatively less vocal than males, but during mating, the females assume a previous vocal behavior, mirroring their male counterpart’s calls. In conclusion, the Blue-rumped Pitta is a fascinating species that feeds on insects and small vertebrates.
