The pied falconet, (Microhierax melanoleucos) is a species of bird of prey in the family Falconidae. It is found in Bangladesh, Bhutan, China, Hong Kong, India, Laos, and Vietnam. Its natural habitat is temperate forests.

These raptors belong to the genus Microhierax, which includes the smallest bird of prey species in the world. The pied falconet, also known as the white-legged falconet, [2] nests in old woodpecker cavities. The species is listed as least concern because of its large home range and stable population size. [1]

Description

The pied falconet is a small black and white raptor, measuring between 7-7 ½ inches and weighing between 55 and 75 g. However it is still larger than the other members of the genus Microhierax. [3] Its face is white with a prominent black patch covering the eyes reaching to the ear coverts with a yellowish beak. The upper parts, including the crown, are completely black. The primaries are black with white wing bars. Its long tail has black upper parts and is black with white bars from below. [3] [4] The pied falconet displays no sexual dimorphism, and the juveniles strongly resemble adult males. [5]

The five species belonging to the genus Microhierax are the smallest members of the order Falconiformes. While they have a very distinct morphology compared to other birds of prey, within the genus Microhierax, they are quite similar. These are allopatric species, except for M. fringillarius and M. latifrons, and mostly likely play very similar ecological roles in each of the habitats as a result of the morphological similarities within the genus. [6] M. melanoleucos is distinguishable from these other members by its white thighs and the lack of chestnut coloration. They are sometimes mistaken for Ashy Woodswallow (Artamus fuscus), however the Pied falconet has blacker upper parts compared to the grey-ash color seen on the Ashy Woodswallow. [5]

Taxonomy

The pied falconet belongs to the family Falconidae of the order Falconiformes. The family Falconidae is split into two subfamilies, the Herpetotherinae and the Falconinae. The subfamily Falconinae is then also split into two tribes. The Caracini include five Neotropical genera: Daptrius, Ibycter, Milvago, Caracara and Phalcoboenus. The Falconini include the genera Polihierax, Falco, Spiziaptteryx and Microhierax . [7] The species belonging to the genera Polihierax and Microhierax are the smallest diurnal raptors in the world. [8] The pied falconet is one of the five species in the genus Microhierax. The four other species of this genus are: [9]

Habitat and Distribution

The pied falconet ranges from north-eastern India to east China and south-east Asia. They are found in deciduous forest edges and clearings in wooded foothills. [10] This species likes clearing such as old cultivation lands with banks and stream. They are usually perched on tree tops while occasionally flying off to catch prey. These are not migratory birds, they are a resident species, staying in the same area for most of the year. [10] [5]

Behavior

Vocalization

This species produces a shrill, high pitched scream and chattering whistle. [3] During the breeding season, the male will produce a rapid sequence of calls to the female as a courtship behavior before mating. The call starts as high-pitched and excited and then slows until the female decides to mate. Afterwards, the male will continue to call for a few more seconds. [11]

Diet

Insects comprise most of the pied falconet's diet, but it also includes small mammals, reptiles and birds. [5] A falconet catches its prey while flying over it and catching it mid-flight or by plucking it out of the foliage of the surrounding trees. [12] Despite being small, pied falconets are quite fast and powerful, allowing them to catch prey as big as themselves or slightly larger. [2]

Reproduction

The pied falconet's breeding season is from March until May. In the early breeding season, the males will initiate interest in mating to a female by presenting leaves to them. The male flies off and returns to a perched female and presents a leaf that he has gathered for the female. Later in the breeding season, usually before copulation, the males will bob up and down very frequently in front of the female while calling frantically. Copulation takes place after this behavior. [11] These small raptors nest in old barbet or woodpecker holes and lay their eggs on a bed of leaves or grass. [4] There have also been recordings of the nesting cavities being filled with insect remains instead of leaves. The females lay three to four eggs which are white in color. [5]

The pied falconet shares many similarities in courtship and mating behavior with the collared falconet (Microhierax caerulescens). The leaf presenting courtship behavior was first observed in the collared falconet. The collared falconet is also known to breed cooperatively. Cooperative breeding is another behavior that is also suspected for the black-thighed falconet (Microhierax fringillarius) and for the other Microhierax species. [6] The pied falconet can be seen in groups of 5 or 6 which suggest that they may also breed cooperatively. [11]

Falcons are birds of prey in the genus Falco, which includes about 40 species. Some small species of falcons with long, narrow wings are called hobbies, and some that hover while hunting are called kestrels. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene.

The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae. The family likely originated in South America during the Paleocene and is divided into three subfamilies: Herpetotherinae, which includes the laughing falcon and forest falcons; Polyborinae, which includes the spot-winged falconet and the caracaras; and Falconinae, the falcons and kestrels (Falco) and falconets (Microhierax).

<span class="mw-page-title-main">Peregrine falcon</span> Fastest known animal and common bird of prey

The peregrine falcon, also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest member of the animal kingdom. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.

It is a small short-billed cormorant usually black above and white below with a yellow bill and small crest, although a mostly black white-throated form predominates in New Zealand. Three subspecies are recognised. Until recently most authorities referred to this species as Phalacrocorax melanoleucos.

<span class="mw-page-title-main">Red-necked falcon</span> Species of bird

The red-necked falcon is a bird of prey in the falcon family with two disjunct populations, one in India and the other in Africa. This medium-sized falcon has bluish grey wings and upper body, a chestnut red cap with short chin straps passing through the eye. The primary feathers of the wing are black and a single black band at the tip of the tail are distinctive. The Indian subspecies Falco chicquera chicquera also known as the red-headed merlin or red-headed falcon is found mainly in the open plains of the India Subcontinent although it is thought to have occurred further west in southeastern Iran. The subspecies Falco chicquera ruficollis found in sub-Saharan Africa is sometimes treated as a full species, the rufous-necked falcon, on the basis of its well-separated geographic range and distinctive pattern. It appears very similar to the Indian form but has dark barring on the upperparts, a rufous breast band, and black moustachial and eye stripes. As in most falcons, the females are larger and falconers in India called the female turumti and the male as chatwa. They hunt in pairs mostly at dawn and dusk, capturing small birds, bats and squirrels.
