Distribution: Afrotropical. Southern ETHIOPIA, SOMALIA, northeastern UGANDA and KENYA south to north-central TANZANIA, a small disjunct population in MOZAMBIQUE, and another disjunct population in southern ANGOLA and NAMIBIA. more....

Subspecies: Monotypic. more....

Taxonomy: Kemp and Crowe (1994) found that this species and all five species of Microhierax clustered separately from other falconet and Falco species, based on their analysis of 24 morphometric characters. From her study of syringeal morphology, Griffiths (1994) also found that the Pygmy Falcon forms a clade with Microhierax erythrogenys that is sister to Falco. Based on nucleotide sequences of the mitochondrial cytochrome b gene, Wink and Sauer-Gürth (2000, 2004) provided yet further confirmation of these relationships, also finding that this species and Microhierax (at least one species, the Philippine Falconet, M. erythogenys) represent sibling genera which form a sister group to the larger monophyletic Falco assemblage. The White-rumped Falcon, which had also been included in the genus Polihierax, is not closely related to the Pygmy Falcon and is basal to Falco and the falconets.

Movements: Probably non-migratory.

Habitat and Habits: Prefers open, semi-arid areas with sparse groundcover and scattered trees, particularly Camelthorns (Acacia erioloba) in arid grasslands (Kalahari, Namib, Karoo). The disjunct populations are separated into islands by tropical woodlands. In southern Africa, this species lives and nests in the haystack-like nests of Sociable Weavers (Philetairus socius) and sometimes near the nests of White-browed Sparrow-weavers (Plocepasser mahali). The distributions of these species closely mirror each other. In East Africa and Sudan, it uses the nests of the White-headed Buffalo Weaver (Dinemellia dinemelli), and the small, disjunct population in Mozambique is said to be associated with nests of Red-billed Buffalo Weavers (Bubalornis niger). Found singly, in pairs, or in small family groups, and often perches high in trees or on telephone poles. more....

Food and Feeding Behavior: Feeds shrike-like on insects, lizards, and small snakes, which it snatches from the ground after descending from an exposed perch and takes back to the perch to eat. Also takes small birds, which it captures in flight. Oddly, pygmy falcons sometimes take adults and nestlings of their weaver "hosts," albeit rarely (De Swardt 1990).

Breeding: Pygmy falcon nests are placed in a chamber of a large weaver nest, and the rim of the entrance becomes coated with pinkish-white droppings. Clutch size is 2-3 eggs, which are immaculate white and rather spherical. Both parents incubate, although the female's share is larger. The male provides food to the female and chicks. Two or more broods may be produced in a single year, if the food supply is adequate. more....

Conservation: Apparently common within each of the disjunct portions of its range. In the southern Kalahari region of South Africa, the artificial introduction of water into the region for livestock has dramatically increased numbers of both Sociable Weavers and African Pygmy Falcons (Mendelsohn 1997). Categorized as a species of "Least Concern" by BirdLife International. more....
