Population and longevity

Hi all- Just found some interesting facts about white-fronted terns on the Birding west coast site.

http://www.birdingwestcoast.co.nz/birding/Birdingdetail/index.cfm/species/71/

The site reports a population estimate of 15-20 000 pairs in 1997. The species is recorded as being in gradual decline, with Northland populations showing a dramatic reported decline.

Longevity record of 26 years reported ( presumably from a banded bird).

Also interesting comments about the sacred element of white-fronted terns , Tara, in Maori culture.
