White-fronted Falconet

The white-fronted falconet, also called the Bornean falconet, is a species of bird of prey in the family Falconidae. Described by the British ornithologist Richard Bowdler Sharpe in 1879, it is endemic to Borneo, where it is found in Sarawak, Sabah, and extreme northeastern Kalimantan. An extremely small falcon, it is only 14–17 cm (5.5–6.7 in) long and weighs 35–65 g (1.2–2.3 oz), being the smallest species of falconet. It has glossy bluish-black upperparts, black flanks and outer thighs, and a black mask. The belly and vent are pale yellowish-brown, while the throat, cheeks, and breast are white. The species can be told apart from other falconets by the colour of its crown and forehead, which is white in males and reddish-brown in females. It has no subspecies.
