The Banded Kestrel (Falco zoniventris) is a bird of prey belonging to the falcon family Falconidae. It is also referred to as the Madagascar Banded Kestrel or Barred Kestrel.
Its closest relatives are the Grey Kestrel and Dickinson’s Kestrel of mainland Africa, and the three are sometimes placed in the subgenus Dissodectes.
Description
It is 27-30 cm long with a wingspan of 60-68 cm.
The upperparts are grey and the tail is dark. The underparts are whitish with dark grey streaks on the throat and upper breast, and dark grey barring on the lower breast and belly. The feet, eyes, and cere (soft skin surrounding the nostrils) are yellow, and there is bare yellow skin around the eye.
Juvenile birds are browner than adults with darker eyes and less bare skin around the eye.
Habitat and DistributionÂ
The Banded Kestrel, also known as the endemic Kestrel of Madagascar, is unique to Madagascar. It is part of a group of elite birds whose ecological and evolutionary roles are unique to the island landscapes. The Banded Kestrel has a limited global range but is fairly widespread in Madagascar. However, its distribution is not uniform.
It is most common in the southern and western parts of the island, where the habitats are still relatively intact. It is localised more in the north and the east and is absent from the high plateau of the central region. This species is found from the sea level to about 2,000 meters in elevation.
Habitat-wise, the Banded Kestrel has a preference for open wooded areas and forest edges. It also prefers deciduous woodland. It avoids dense, closed canopy rainforests and open, treeless areas. It is a common sight in Transitional Habitats where forest gaps or natural clearings are created by human activity.
Its range overlaps with some of Madagascar’s protected areas, but also includes secondary or degraded forest. This shows a degree of resilience to disturbance. As Madagascar continues to experience rapid habitat conversion and deforestation, the distribution of the kestrel may be fragmented.
Calls / Vocalisations
The species has a shrill, staccato, chattering call and a sharp, screaming call, but is usually silent outside the breeding season.
Feeding Behavior
The Banded Kestrel, unlike some of its aerial relatives, is a perch hunter. It does not hunt or hover on wings, as is more common for kestrels that live in open areas. It prefers to perch inconspicuously and quietly on a branch while scanning the forest floor for any movement. This strategy suits the woodland and forest environments in which it lives. According to iNaturalist, this species is well documented.
Its diet is varied but heavily focused on small prey. This includes reptiles. Its diet is dominated by Chameleons and Day Geckos. Both are abundant and highly developed in Madagascar. They are usually ambushed by a predator and then snatched with force from tree trunks or branches. According to IUCN Red List, this species is well documented.
The Banded Kestrel also feeds on large insects, including grasshoppers, as well as beetles. They are caught in mid-air or are grabbed by leaves and bark. It sometimes preys upon small birds, particularly nestlings and fledglings. However, such cases appear to be rare or an opportunistic feeding behaviour rather than a normal feeding pattern. It’s a low-energy strategy that relies on strategy and ambush rather than prolonged effort. It is a great advantage in hot and dry environments where energy conservation is essential.
Breeding and Nesting
The breeding season of the Banded Kestrel is between September and December. This coincides with Madagascar’s early spring and summer. During this time, the pairs are more vocal and visible, and engage in territorial displays and courtship displays.
The Banded Kestrel’s nest is a simple scrape, unlike many other birds of prey, which build elaborate nests. The nest is usually a scrape and is often found in an abandoned bird nest.
Nests are often found in holes in trees, or clusters of epiphytic plants — those plants that grow without absorbing nutrients from the tree. These nests protect predators as well as provide shelter from the elements. This is especially true in Madagascar’s diverse climate zones.
The typical clutch is 3 yellow eggs that are carefully incubated. There is very little information about the duration of incubation or fledging. The division of parental duties and the role of the parents are also unknown.
Conservation
On the IUCN Red List, the Banded Kestrel has been classified as a species with Low Concern. This classification reflects the large range of the Banded Kestrel within Madagascar, and its apparent toleration of mildly disturbed environments. The designation is not a sign of complacency.
Madagascar’s ecosystems face immense pressure due to slash-and-burn agriculture, logging, and charcoal production. Also, the growing population is putting immense strain on them. The Banded Kestrel, as a woodland and forest species, is particularly vulnerable to fragmentation. It can survive in secondary forest and semi-disturbed regions, but severe degradation of habitat or total clearing leaves it with limited options.
A second concern is the fact that little is known about the Kestrel’s population trend, its reproductive success, or its precise range limits. Conservation planning is speculative without robust data. Madagascar’s protected areas do offer some refuge, but funding and enforcement are often lacking.
The Banded Kestrel is a resilient species due to its adaptability to the environment, wide diet, and opportunistic behaviour when nesting. This resilience is not invulnerability.
Conclusion
The Banded Kestrel is a species that represents the quiet brilliance in Madagascar’s wildlife. It’s not loud or flashy, but elegant and efficient, with finely adapted adaptations to its environment. Its barred feathers and yellow eyes speak of its skill as a predator. However, its quiet presence among the trees reminds us that some birds are just as remarkable.
The fate of the Banded Kestrel is closely tied to that of Madagascar’s forests, as it is with many other species unique to Madagascar. Conservation efforts, habitat protection, and scientific research are key to ensuring this tiny but powerful raptor can continue to dominate the tree-lined clearings on its island.
The Banded Kestrel, in the end, is more than a bird of prey. It is a symbol for Madagascar’s unique evolution. A living thread in a fragile ecosystem, it is also a reminder of the fact that the most compelling nature stories are often whispered and not shouted.
