As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Water bird numbers reveal long-term decline of Menindee Lakes' health

21 January 2019 — 11:50pm
Water bird numbers at the world famous Menindee Lakes, near the site of this year's massive fish kill, are in long-term decline, amid an ongoing failure to manage water levels to match weather fluctuations, leading ecologist Richard Kingsford says.
Bird numbers at the lakes in far-western NSW peaked at about 140,000 in 1985, according to surveys taken annually since 1983. For each good wet year since that record, the bird count has been falling.
Water populations "are a bit like a tennis ball...but the bounce is just getting lower and lower" during good years, said Professor Kingsford, who is director of the Centre for Ecosystem Science at the University of NSW.
The lakes "are one of the hotspots for water bird in eastern Australia, and they've been declining for some time".
