Biak Paradise Kingfisher

Tanysiptera riedelii

The Biak paradise kingfisher, with its scientific name Tanysiptera riedelii, is a resplendent avian jewel endemic to the Indonesian island of Biak. This species is distinguished by its striking turquoise-blue upperparts and pristine white underparts. The bird's impressive tail streamers and a vivid reddish beak add to its allure, making it a sight to behold in its natural forest habitat.

Identification Tips

Adults measure approximately 14 inches (36 cm) from beak to tail tip, with the tail accounting for a significant portion of this length. The crown, nape, and sides of the head shimmer in glossy turquoise-blue, while the rump and base of the tail feathers are white. The underwings present a stark contrast in black. Notably, the two central tail feathers are elongated and end in unique racket-like lobes. The bird's bill is long, stout, and a striking red color.


The Biak paradise kingfisher is a forest dweller, favoring the lush and verdant habitats of its island home.


This species is confined to Biak Island in Indonesia, where it has evolved in isolation, leading to its current distinctiveness.


While specific studies on the Biak paradise kingfisher are limited, it is believed that its behavior mirrors that of its close relative, the common paradise kingfisher of mainland New Guinea. It likely perches on low branches, diving down to capture insects and earthworms from the forest floor.


Breeding habits are inferred from its relatives, suggesting that it nests in tree cavities, hollow branches, or even in holes within arboreal termite nests.

Conservation status

The Biak paradise kingfisher is classified as Near Threatened by the IUCN. Although it is relatively common within its small range, its forest home is threatened by logging activities. However, the species shows some adaptability to secondary growth forests, provided that tall trees are available. Conservationists are concerned about a potential decline in population due to habitat loss.

What Our Birders Say
Fantastic app - Love it!
Love this app and have used it almost daily. Lots of species information and easy to use. Love seeing birds spotted by other users in the UK and worldwide.

Sense of Community
A great app, which is continually being improved. What really comes through is the passion of those behind the app. The sense of community is brilliant, so much help and support provided to new and/or in experienced birders.
Just what birding needs
We need more fun in birding, for years it has had a reputation for being up tight and stuffy and only perused by retirees and anoraks. Birda helps change that perception and firmly brings birding into the 21st century! Fun, interactive while still contributing to science and conservation. If you aren’t on it, why not??
Really great app
It’s easy to use and it’s fun to log the birds you notice on a walk or just in your garden. There’s a option to record the birds you see in a session which is really nice. Good excuse to stop for a while and just watch birds. I am also enjoying the information part where you can find out fact about birds from all over the world.
Fantastic App
This is a really lovely app, for everyone interested in birds - from newbies to old hands. There is a very friendly feel to the community and you will genuinely learn a lot as you record your sightings and photos. There are lots of badges and competitions to keep you engaged, and a host of really useful features.

Very wholesome app: I joined this app with a new interest in watching birds to help me find out what I was spotting. The community is very active in helping identify birds which is great and everyone is very kind so it’s just a nice wholesome community. I would definitely recommend this for any bird spotter 😃
Great app for beginner twitchers
I’ve had a passion of photographing birds for a long time now but have only just gotten into proper birdwatching, and this app is brilliant for those just getting started. There is a great sense of community among users and the app is very easy to use and professional. Awesome app altogether
