Silvery kingfisher description

GenusAlcedo (1)

This tiny yet distinctive kingfisher, with largely black and white plumage, is found only near small streams and rivers in the Philippines. There are two subspecies of the silvery kingfisher; Alcedo argentata argentata and Alcedo argentata flumenicola (2). A.a. argentata has a black head with silvery white spots, black wings and a silvery white back. The throat and belly are also a silvery white, and the breast is blackish with a blue sheen. A.a. flumenicola is smaller, with a purplish wash on the underparts, and a creamy-coloured throat (2). The dagger-like bill is black and the legs are a startling bright orange-red (2).

Length: 14 cm (2)

Silvery kingfisher biology

Like other kingfishers, the silvery kingfisher makes spectacular dives into the water to capture its prey. It sits still on a low perch, watching carefully for the movement of a small fish or crab. When spotted, it dives into the water and returns to its perch with its meal (2) (3). Kingfishers often stun their slippery prey by beating it on a hard surface to make it easier to control and swallow (4).

The silvery kingfisher nests in holes in streamside banks. Information regarding its breeding biology is limited to a female with an enlarged ovary collected in May, and juveniles collected in April to May (2), therefore its is assumed that eggs are laid in February and March (5).


Silvery kingfisher range

Endemic to the Philippines. A.a. argentata inhabits the islands of Dinagat, Siarao, Mindanao and Basilan, while A.a. flumenicola can be found on Samar, Leyte and Bohol (2) (3).


Silvery kingfisher habitat

The silvery kingfisher is generally found on rocks and along banks of forest streams and small rivers. It also inhabits pools adjacent to forest, primarily below 1,000 meters (2) (3).


Silvery kingfisher status

Classified as Vulnerable (VU) on the IUCN Red List 2007 (1).

IUCN Red List species status – Vulnerable


Silvery kingfisher threats

The silvery kingfisher was once much more widespread and common, but numbers have reduced rapidly as a result of loss and degradation of lowland forest (2). On Mindanao, only 29 percent of the forest cover remains, whilst on Bohol just six percent is still standing (6). These remnant forest patches continue to be cleared, with most remaining forests being leased to logging concessions or covered by mining applications, the acceptance of which would give companies the right to clear forests (6). Deforestation causes soil erosion, increasing siltation in the streams and rivers; while mining and the increased use of fertilisers, herbicides and pesticides by farmers pollutes the waterways of the Philippines creating a habitat unsuitable for the silvery kingfisher (6) (7). The forest at Bisling, Mindanao, is an important site for the silvery kingfisher, but it is being cleared and replanted with exotic trees for paper production (5). Even protected areas are not safe from these threats; Rajah Sikatuna National Park on Bohol is also being impacted by tree-cutting, agricultural expansion and soil erosion (2)


Silvery kingfisher conservation

The silvery kingfisher occurs in a few protected areas, such as Rajah Sikatuna National Park on Bohol, and Agusan Marsh Protected Area on Mindanao (2). However, as mentioned above, this appears to offer only nominal protection. The establishment of further protected areas has been proposed (7), but these, and existing areas, need to be carefully managed and protection enforced if the beautiful silvery kingfisher is to survive (2)
