Prions wrecked

More than a week of severe storms blowing up from the Antarctic has left thousands of sea birds wrecked across New Zealand, not just along the coast but well inland. A local landowner brought in a bird for me this morning, wanting me to help indentify it. After much measuring of the dead bird and consulting of the identification guides, we determined quite confidently that it was a broad-billed prion, and not an antarctic prion which were being reported as being wrecked in large numbers in and around Wellington. The local bird rescuer, the reverend Robin List, confirmed that all the birds he had coming in from around the Wairarapa were broad-billed. A wreck is when very large numbers of seabirds die and become wrecked around the coast. Sometimes it involves mainly one species, or at other times several species. Some wrecks seem to be caused by storms catching young birds a few days after leaving their nests, others by storms combined with a food shortage. Birds found dead or dying

Spur-winged Plover

Walking along North Street with my dog, always there are spur-winged plovers to be seen in the paddocks. There used to be two or three pairs but this winter I see just the one pair. I hope this is not a trend! Travelling throughout New Zealand, especially through farmland, the one bird that one is most likely to see is the spur–winged plover, very often being harried by and, in turn, harrying a harrier hawk. However, spur-winged plovers did not used to be so widespread, the first pair recorded breeding at Invercargill airport in 1932. In spite of the heavy predation of their chicks by harrier hawks and our national propensity for using birds for target practice, their numbers have now become so great that there is talk of culling them. Not a good reason, I would think. There are two well marked races of this bird; the smaller race, Vanellus miles novaehollandiae , originally just bred in the south–east of Australia but then extended its range to Tasmania and New Zealand.
