Geographic Range
Madagascar red owls (Tyto soumagnei) are endemic to the island of Madagascar. Previously they were thought to live strictly in the eastern and northeastern parts of the island, however a study in 2002 noted two sightings of Madagascar red owls in Kalambatritra Special Reserve in south central Madagascar. This extends their previously known range by 500 km to the south. (Bruce, 1999; Irwin and Samonds, 2002)
Habitat
Sea level to 2000 m
( to 6561.68 ft)
Madagascar red owls are known to live and hunt along forest edges, rice paddies, and tavies (areas of deforestation due to slash-and-burn farming techniques). They have been documented to inhabit elevations from sea level to 2000 m.
Diurnal roosting has been documented along rock ledges and cave entrances. It has also been noted that during diurnal roosting, Madagascar red owls were spotted with large leaves covering their heads. It has been suggested that weather may play a role in diurnal roost selection, as the area is known to receive substantial rainfall. (Cardiff and Goodman, 2008; Langrand, 1990; Thorstrom, et al., 1997)

Madagascar red owls are small owls, about a third smaller than common barn owls. One individual documented in 1997 weighed 323 g and had a body length of 27.5 cm. They are orange-red in color on the head, back, and stomach, though lighter underneath, and are speckled with black, sooty dots. They also have a short tail and an orangy-white to grey facial disk with blackish eyes. Males and females are similar in appearance, as are the juveniles though young tend to be brighter in color. (Bruce, 1999; Langrand, 1990; Thorstrom, et al., 1997)
Reproduction
There is no known information on mating systems for Madagascar red owls. However, their habits are presumed to be similar to those of barn owls (Tyto alba). They perform chasing courtship flights, in which the male leads the female. The male will show the female nesting sites as well as bring her food. Barn owls form monogamous pairs for life. (Elphick, et al., 2001)
10 weeks
4 months
Very little is known about the reproductive habits of Madagascar red owls, due mainly to their reclusiveness. Only one nest has been described. It was found in a tree cavity 23 m above ground and contained two recently hatched individuals that appeared to stay in the area for four months. These chicks hatched in September and fledged 10 weeks later. In closely related barn owls (Tyto alba), the breeding season and brood size depends on food availability. In years with abundant resources, they have been known to lay two clutches. In lean years, clutch size decreases or some chicks may starve. (Bruce, 1999; Ehrlich, et al., 1988; Elphick, et al., 2001)
No information is known about parental investment for Madagascar red owls. In closely related barn owls (Tyto alba), the female incubates the eggs and the male will forage and feed her during this time. Owlets are born altricial, with downy feathers and eyes closed. Both male and female barn owls tend the young. (Ehrlich, et al., 1988)
Lifespan/Longevity
The lifespan of Madagascar red owls is unknown.
Behavior
Madagascar red owls are nocturnal hunters that engage in diurnal roosting. They are generally found living alone or in pairs. (Thorstrom, et al., 1997)
Home Range
Territory size for Madagascar red owls is unknown.
Communication and Perception
They emit a screech that has been recorded to last 1.5 seconds. This screech is utilized when leaving their roost and in response to other Madagascar red owls. They also have been heard making a 'wok-wok-wok' sound followed by a single, brief, and loud alarm that differs from the previously emitted wok sound. Like all birds, Madagascar red owls perceive their environment through audio, visual, tactile and chemical stimuli. (Langrand, 1990; Thorstrom, et al., 1997)
Food Habits
Madagascar red owls are carnivores. Examination of pellets indicated that their diet consists of native insects, reptiles, and mammals in addition to introduced brown rats (Rattus rattus). 99% of their diet consists of prey ranging in weight from 12.8 g to 102.7 g. (Cardiff and Goodman, 2008; Goodman and Thorstrom, 1998)
Primary Diet
carnivore
(Eats terrestrial vertebrates)
Animal Foods
mammals; amphibians; reptiles; insects
Predation
Predation has not been documented for Madagascar red owls.
Ecosystem Roles
Due to their reclusivity, nothing has been recorded regarding their relationships with other organisms on Madagascar beyond their dietary intake. Many owls play a significant role in population control of prey species.
Economic Importance for Humans: Positive
There are no known positive effects of Madagascar red owls on humans.
Economic Importance for Humans: Negative
There are no known adverse effects of Madagascar red owls on humans.
Conservation Status
IUCN Red List of Threatened Species [Link]
Vulnerable
More Information
CITES [Link]
Appendix I; Appendix II
Madagascar red owls are considered vulnerable by the International Union for Conservation of Nature (IUCN), with a decreasing trend in population. This is due mainly to deforestation that not only destroys their habitat but the habitat of their prey as well. This deforestation is the result of commercial logging and uncontrolled burns associated with farming. ("Tyto soumagnei", 2010)
