The link between bird conservation and "citizen science" is the focus of Whanganui's next Nature Talks presentation.
The talk will be led by Peter Frost, the regional representative for Birds New Zealand, who has researched birds for over 40 years.
Two years ago a Parliamentary Commissioner for the Environment report showed that four-fifths of the country's bird numbers were in trouble.
Frost said that was based off analysis of bird distribution from two atlases covering 1969 to 1979, and 1999 to 2004, which were created from the input of thousands of citizen scientists.
