Aotearoa New Zealand has ten official Great Walks. Te Papa natural history curator Dr Colin Miskelly has walked (or paddled) them all and kept records of the birds that he encountered along the way. In this second blog in the series, he reports on the birds encountered while paddling down the Whanganui River.
An anomalous Great Walk
The Whanganui Journey is the odd one out in the Great Walk network. It is the only one that is traversed by boat rather than by boot. The journey is either 3 or 5 days in duration, depending on whether the starting point is at Whakahoro, or further upstream at Taumaranui.

We started at Whakahoro and followed the river as it meandered through dense forest and below towering cliffs, to the exit point at Pipiriki, 88 km downstream. Apart from two overnight stops close to the river, the only time we left the river was to walk 3 km (and back) to the infamous Bridge to Nowhere.

This bridge is a poignant reminder of a post-World War I attempt at settlement and farming in the Mangapurua catchment. By the time the bridge was completed in 1936, most of the families had departed, penniless.
Birding while paddling
Travelling by canoe or kayak restricts bird-watching opportunities in several ways, and contributes to the Whanganui Journey having the lowest ‘endemic bird score’ of the ten Great Walks (see Birds of the Great Walks of Aotearoa New Zealand for an explanation of the scoring system).

The first restriction is that the route followed can only sample a single habitat type – a river with forested margins. The second is that river noise, and the sounds generated while paddling, mask many of the bird calls that may be emanating from the forest.

The river itself has relatively few wetland bird species on it, and those we saw scored zero or one on the bird endemism score (these included Little Shag | Kawaupaka, Black Shag | Māpunga, Mallard | Rakiraki, and New Zealand Kingfisher | Kōtare).
Whio | Blue Duck is in its own endemic genus (= a score of 3) and breeds on many of the tributaries of the Whanganui River catchment. They are occasionally reported on the main river, but we did not see any during our 3 days of paddling.

A few forest birds were seen flying across the river, with a highlight being the distinctive silhouette of the often-heard but rarely-seen Long-tailed Cuckoo | Koekoeā.
Forest birds
When we were able to venture into the forest, we were able to find several other endemic bird species, including the ‘deep endemic’ Rifleman | Tītitipounamu and Whitehead | Pōpokotea.

North Island Brown Kiwi | Kiwi-nui can be heard at some of the camp sites and huts along the Whanganui River, but we did not hear any.
However, a non-bird nocturnal highlight was several Long-tailed Bats seen at dusk at John Coull hut.
