In a few days it will be spring and the birds will be in full song.
But in some parts of the country it will be an extremely muted song.
In fact there are now areas known as ‘bird deserts’ where there are virtually no native birds.
We know these regions exist because birdwatchers have just spent five years in the field finding out how many birds there are, and where they live – information for the latest edition of the New Zealand Bird Atlas.
Richard Langston with a story on the plight of our birds. link
Scientific knowledge about New Zealand birdlife took a great leap forward today as the Ornithological Society of New Zealand published the Atlas of Bird Distribution in New Zealand 1999-2004.
The atlas was launched today at Government House in Wellington by the Administrator of the Government, Rt. Hon. Dame Sian Elias. Birds are some of the best natural indicators of the health of our environment – an environment we like to promote as clean and green.
President of the Ornithological Society, Professor Richard Holdaway said that the bird distribution atlas has demonstrated dramatic and rapid changes in bird distribution in all parts of the country since the 1970s. As land use has changed, so have the communities of bird species in those areas.
Examples of this included areas that have changed from exotic forest to dairying, and areas that have reverted from cleared land to native scrub. Species that did well in the first habitat have been pushed out as the land was converted. Atlas project Convenor, Christopher Robertson notes that “Green in colour we may be, but these atlas surveys continue to demonstrate that some of that greenness is both increasingly monocultural, and the battleground of territorial invaders among the avifauna. New Zealand endemics are retreating to enclaves where introduced mammalian predators increasingly threaten the food supply, productivity, and individuals of remnant species.” more
Outward bound: North Island robins the first birds to be transferred out of Karori Sanctuary
Until now wildlife has arrived at Karori Sanctuary on a one-way ticket. But seven years after the first birds were released at the Sanctuary, bird numbers are booming and the Sanctuary is about to make its first outbound transfer – taking ten of its North Island robins to supplement the small population on Matiu/Somes Island. more
