Huge declines in woodland birds
|
The greatest disappearing act has been that of the nightingale, whose numbers fell by 95% over the study period.
The causes of the varying fates of British woodland birds are many and varied.
changes in habitat outside of the UK are also having a major impact, particularly on migrant woodland species that spend part of the year in Africa
the species that winter further south in the humid tropics of west Africa that were suffering
land use changes leading to habitat degradation
This research will hopefully enable us to identify what the changes happening in Africa are that are causing these declines and ultimately, we hope, to enable us to come up with suggestions for solutions that would benefit not just the birds but also the people who live there
availability of food explains other trends
More than 80% of lesser spotted woodpeckers have gone
data on 49 species between 1967 and 1999
The results of the survey have not been reported before.
