Red avadavats can be found throughout southern and southeastern Asia, from India to the Malay Peninsula and surrounding islands. These birds have been successfully introduced to the Philippines, Japan, Puerto Rico, and Hawaii. (Goodwin, 1982)
Red avadavats are found in grassy areas, such as jungle clearings, gardens, and meadows. They also frequent sugarcane fields and areas near bodies of water, such as marshes. Red avadavats are accustomed to tropical temperatures and will lose plumage intensity in cooler, dryer environments. ("avadavat", 2009; "Red Avadavat", 2009; Goodwin, 1982)
Males and females molt into breeding plumage each year. During the breeding season males have a deep red crown and back, and there are white streaks under the eyes. The sides of the head, down the breast and the undersides are scarlet. The wings, tail overfeathers, and flanks are dark red with white spots. The tail feathers are black. The beaks of the males are red. When females go into the breeding season they often molt and the chest and underbelly become a brighter yellow-orange. ("Red Avadavat", 2009; Goodwin, 1982; Harrison, 1962)
At the end of the breeding season, males begin to molt to a plumage that resembles the coloration of females. The color of the underbelly ranges from a creamy tan to creamy yellow, and there are black streaks under the eyes. The crown, back, wings and tail are dark brown with fewer white spots than males in breeding season. Juveniles of this species are dull grayish brown all over. This is the first molt from the nestling stage. Nestlings are marked by dark skin and down, and have markings around the mouth. (Goodwin, 1982)
Red avadavats have been introduced into many countries as a cage bird. Under poor conditions, plumage coloring loses its intensity. When they are kept at warm temperatures (40 degrees Celsius), kept in sunlight, and fed appropriately, the plumage will remain bright. (Goodwin, 1982)
Male red avadavats use their bright red plumage in addition to a mating dance to attract females. The dance begins with males, a grass stem or feather in their mouth, deeply bowing with feathers erect. Usually the birds sing and hop between bows. Both males and females display. When the birds have paired, they separate from the larger group to build a nest. Red avadavats are monogamous within a breeding season, but no information could be found on potential life long monogamy. (Harrison, 1962; Langham, 1987; Harrison, 1962; Langham, 1987; Harrison, 1962; Langham, 1987; Goodwin, 1982; Harrison, 1962; Langham, 1987)
In captive birds, males who are paired will mimic a display similar to begging of fledging young followed by an attack if a female or other bird comes too close. Females will display aggression against other females as well as brown males if a male in breeding plumage is present. (Goodwin, 1982)
Red avadavats breed in the second half of the rainy season and into the following dry season. Breeding months vary regionally. Males begin molting into their bright red plumage as the breeding season begins. Out of the breeding season, males often do not entirely lose their red plumage before beginning molting for the breeding season. Breeding pairs have between 4 to 6 eggs in a clutch. The eggs take around 11 days to hatch; hatchlings take around 20 days to fledge. (Goodwin, 1982; Langham, 1987)
The eggs of Bombax) and grass. Parents exhibit aggressive behaviors if another bird of the same or a different species gets too close to the nest. Both parents feed nestlings. If females produce another clutch before the first set of young are able to care for themselves, males will take charge of feeding the young. ("Red Avadavat", 2009; Goodwin, 1982)are incubated by both parents during the day. Females usually take over at night. Before fertilization, both males and females collect grass and sticks to create a nest. The nest is lined with soft feathers, tree cotton (found inside seed pods of trees of genus
No information could be found on lifespan in natural or captive environments. (Goodwin, 1982)
When not in the breeding season, red avadavats stay in large social flocks of up to 100 birds. The term for this gathering is clumping. During this time they engage in social preening (grooming) which may serve to create and maintain bonds. Allopreening is also common among breeding pairs and between non-breeding males and females. However, mated males and females show aggression towards other conspecific males and females. Red avadavats can perch upright between two vertical posts. This is a product of having a large grip and ability to extend the legs in opposite directions. (Goodwin, 1982; Harrison, 1962; Sparks, 1963)
Nestlings often perform a "begging" behavior for food. They may perform a variety of behaviors from simply opening their mouths in a resting posture to wing fluttering. Adults will not usually adopt fledglings in the wild, unless their own fledglings are ready to leave the nest. (Goodwin, 1982)
Little information can be found on the home range of red avadavats in nature. They are not a migratory bird. Red avadavats protect the nest, but when not in the breeding season they live in large groups. They nest and remain close to the ground, generally. (Goodwin, 1982)
Red avadavats have long vocalizations used as location calls. Females have a shorter, softer version of the call, and use it less often. Both males and females of the species use voclizations during mating displays. At the start of the breeding season, males change their plumage from brown to red. When red avadavats are displaying aggressive behaviors they will use a shrill call. A higher pitched call is used when members of the species perceive danger to their young. Young learn songs from their fathers while in the nest. (Goodwin, 1982; Harrison, 1962)
Red avadavats feed on a variety of food sources. In captivity red avadavats prefer seeds from sprouting millet. When feeding young, they prefer ant larvae and pupae, centipedes and caterpillars. They are known mainly as ground feeders. ("Red Avadavat", 2009; Goodwin, 1982)
To protect against predation, red avadavats stay in large groups, especially during the non-breeding season. Also, when they are alarmed, they move their tails from side to side and at a down angle. During the non-breeding season, brightly colored males lose their plumage and become brown, much like the females. This brown plumage may serve as camouflage during the dry season. Both breeding and non-breeding birds use a shrill call if they perceive danger, warning other group members. There is little information on predators of red adavavats. (Goodwin, 1982; Harrison, 1962; Sparks, 1963)
Because red avadavats feed on seeds and small insects, they likely have a role in seed dispersal as well as pest control. They are also prey for larger predators. There is little additional information on the roles red avadavats have on the ecosystem. ("Red Avadavat", 2009)
Red avadavats are popular cage birds. Common names in the pet trade are strawberry finch or strawberry waxbill. The name originates from the scarlet red of the neck, chest, and underbelly, as well as their white spots. (Goodwin, 1982)
There are no known adverse affects ofon humans.
According to the IUCN Red List red avadavats are an animal of least concern because of their large population size and large geographic range.
