Interesting sightings from Braided River surveys

Postby andrewcrossland » Sat Nov 03, 2018 10:58 am

Hi folks,

There's a series of braided river surveys being undertaken in Canterbury currently, organised by Environment Canterbury, with with participants from DoC, CCC, BRAID, OSNZ, WMIL and other groups & volunteers.

Some interesting sightings are:

Black-fronted Dotterels on the Waiau, Waimakariri and Selwyn Rivers

a pair of Black Stilts (both reportedly banded) on the Waiau

Increased Wrybill numbers on the Waiau River and good numbers on the lower Waimakariri

At least 6 White-winged Black Terns on the mid Waimakariri including 3 birds in full breeding plumage and 3 others in varying stages of acquiring BP (so all are following a Southern Hemisphere moult cycle - so watch this space!)

Hi Andrew,
Has there been any further news of these WWBTs seen on the Waimakariri since your post?

Thanks to some incredible work by Environment Canterbury and its contractors managing anti-environmental human activities and reducing populations of both mammalian and avian predators there was a sizeable black-billed Gull colony and an impressively large est.150 pair Black-fronted colony in the Weedons-Ross Rd area of the Waimakariri River. Also nesting were at least 8 pairs of White-fronted Tern (28 km upstream of the sea) and possibly 1 pair of Caspian terns. At least 4 of the 6 WW Bl terns we'd found on the Nov census were hanging out in this area, including 1 bird in full breeding plumage and 3 adults either going or, or coming out of breeding plumage. They were under observation mainly by Niall Mugan and myself, and the ECAN ranger team also kept an eye out for them. But, although associated with the B/F Tern colony and acting defensively at times, we couldn't prove they nested, and so far no juvs have been seen. Unfortunately we couldn't really publicise these birds too much because the area was the site of Black-backed Gull control operations and there was a lot of sensitivity around that.

We'll be out in force again next spring, chasing the holy grail!!
