Research causes of decline in woodland birds
The British Trust for Ornithology (BTO) has initiated a programme to research the decline of UK woodland birds. Volunteers are used at a large number of sites, however identification of woodland species is one of the most difficult aspects of ornithological fieldwork.Dense vegetation means that birds must often be identified by songs or call alone.
To this end Restore Our Planet has supported the BTO’s production of a CD containing the voices of all target species and those they are likely to be confused with. Volunteers will be armed with these in order to help them in the tricky identification process.
