Leaving the birds of the river from my last post behind, continuing along a bike trail in Canterbury New Zealand still revealed many new birds to be seen. The bike trail didn’t quite land us at the beach as we’d expected, but instead at the Ashley River estuary. The tide was quite low and there were shorebirds aplenty to be seen.
In one of the main channels of the river outlet were quite a few birds enjoying the calm flow of the inter-tidal estuary. A few familiars we’d already seen, including the Paradise Shelduck (a pair of course) and the Spur-winged Plover were among some new species. Sacred Kingfishers zipped by overhead, calling loudly, moving so fast they were impossible to photograph, must like the Belted Kingfisher I am familiar with in BC.
Pied Stilts roved along the sandy shore in search of critters to eat, their long pink legs and black-and-white colouring conspicuous among other birds, though the South Island Pied Oystercatcher has equally beautiful black-and-white colouring. They strongly reminded me of our own Black Oystercatchers with red eyes and pink legs.
But no birds were as familiar as the Mallards that floated in the deeper water of the channel among a flock of Southern Black-backed Gulls. The mallard was introduced to New Zealand as early as 1870 and within 100 years populations really took off. Sadly, they have out-competed the native Grey Duck or parera in most areas of New Zealand, who can mainly only be seen in wilder regions.
Further along toward the sea was a pair of cormorants perched on a brush pile: a Little Shag and a Pied Shag. Further away and a lot more shy, I spotted a Bar-tailed Godwit and a Banded Dotterel. The Banded Dotterel, or Double-banded Plover, is endemic to New Zealand, frequenting estuaries and rivers. Northern populations winter in Australia while southern birds move north. They are unfortunately very vulnerable to the predators introduced to New Zealand, including cats, stoats, rats and weasels. This is yet another sad example of the dangers of introducing non-native species.
The Bar-tailed Godwit is also known as the Eastern Bar-tailed Godwit, especially in North American where they breeds in Alaska. They tend to leave New Zealand in March and return in September. A female bird tracked by scientists was found to have made the longest ever nonstop flight by a bird – a whopping 11,500km in just nine days! Incredible. Meanwhile, humans spend thousands of dollars and tons of jet fuel to make the New Zealand Birds Onlinesame journey. If that doesn’t make you think nature is cleverer than humans, I don’t know what will.
