Braided river birds: overview
More than 80 species of birds are found along braided rivers from the mountains to the sea. However, only 6 birds have evolved to live in this unique environment, and all are endemic, that is, they live only in New Zealand: black-billed gull | tarāpuka (endemic), black-fronted tern | tarapirohe, banded dotterel | pohowera, black stilt | kakī, South Island pied oystercatcher | tōrea, and wrybill | ngutupare.
The remaining 4 native species: Caspian tern | taranui, red-billed gull | tarāpunga, white-fronted tern | tara, and pied stilt | poaka have been included here because they are often mistaken for the endemic braided river birds, and in the case of pied-stilt | poaka, present a problem for the endemic black stilt | kakī for reasons that are explained on their respective pages.
All of these birds are taonga species for Ngāi tahu and as such, have special cultural, spiritual, historic, and traditional associations.
The populations of all braided river bird species are in decline; some are at risk of extinction.
Important!
If you are monitoring or planning to monitor braided river birds, please first see the Department of Conservation PDF: ‘Protocol for best practice in monitoring braided river birds’.
Which birds are found on what rivers
Go to the Canterbury Maps Braided River Bird Data – Web App, (see images below). This mapping tool gives you access to a wide range of data. Please note that there are gaps in the data. This is in part because some older records are not available to be digitalised; many remote areas have not been surveyed; some species such as black-billed gulls | tarāpuka are visible from the air during the breeding season as they nest in closely-spaced colonies, so aerial surveys can be regarded as reasonably accurate; small cryptic species such as wrybill | ngutupare and dotterels | pohoweraare are much harder and more labour intensive to count.
How to use the database. Due to a technical glitch the image quality is nottideal and the sound quality drops for about 30 seconds during the transition between Miles and Frances speaking before returning to normal. But do take the time to watch as it will save you heaps of time.
