Nearly 200 seabirds have been found dead along Waikato's west coast beaches.
A total of 184 short-tailed shearwater, a migratory bird that typically breeds on the islands between Tasmania and Victoria, have been washed ashore between Waikorea beach and Taharoa, south of Kawhia.
It is not known when the birds died and were washed ashore,
but numbers are said to be "unusually large" by one expert.Hugh Clifford, who organised the beach patrol on behalf of the Waikato branch of the Ornithological Society, said the number of short-tailed shearwater found this year was much higher than normal.
"There would be millions of them passing down through the Tasman Sea on the southern migration.
"Some of them were pushed closer to New Zealand and the food conditions may have been unfavourable, causing them to perish."
Each year during the southern hemisphere winter, the short-tailed shearwater migrate about 15,000 km to the Northern Pacific, before making their way back towards southern Australia to breed around October.
