CORVID RESEARCH PROJECT
SongBird Survival is funding research by the Game & Wildlife Conservation Trust (GWCT), who have well recognised expertise in this field. The nationwide project aims to deliver the first definitive evaluation of the impact of growing numbers of corvids on the producivity of our farmland songbird population.
THE CROW FAMILY
Corvids are generalist feeders but it is well known that their diets include the eggs and nestlings of many songbirds. Research in this area is sparse and of questionable quality.
CORVID NUMBERS HAVE BEEN
INCREASING OVER 40 YEARS
- Magpie - up 97%
- Carrion Crow - up 89%
- Jackdaw - up 107%
We have lived in a managed environment, a ‘synthetic’ ecosystem, since Neolithic Times. The numbers of farm workers and gamekeepers who hitherto managed our pest species are a mere fraction of what they were 100 years ago.

WHAT EFFECT IS THIS HAVING ON SONGBIRDS?
Predation has already been proved to have a serious effect on ground nesting birds and waders. No experimental research exists on the impact of corvids on songbirds.
Songbird numbers have crashed in one generation:
- Corn Bunting - down 90%
- Yellow Wagtail - down 72%
- Skylark - down 58%
- Yellowhammer - down 55%
- Linnet - down 55%
- Habitat loss and modern farming usually get the blame but both of these have actually been improving in recent years
- Rising levels of uncontrolled predation are ignored - cats, crows, grey squirrels, foxes, badgers & birds of prey are all at record levels
THE STATE OF RESEARCH
- Existing research is out-of-date and flawed
- New high quality research is urgently needed
- No fully experimental study of songbird predation has ever been carried out in the UK
Funding these projects
