The index of abundance of terrstrial breeding birds is an index which combines information on the numbers of selected species, rather than their spatial coverage. Terrestrial breeding birds in Scotland comprise both resident and migratory species. They include familiar garden species such as blackbird (Turdus merula) and robin (Erithacus rubecula), woodland species such as willow warbler (Phylloscopus trochilus) and goldcrest (Regulus regulus), farmland species such as linnet (Carduelis cannabina) and goldfinch (Carduelis carduelis), and uplands species such as raven (Corvus corax) and black grouse (Tetrao tetrix). This indicator is measured using index numbers, 1994 has been set equal to 100.

Data is mainly provided through the British Trust for Ornithology's volunteer Breeding Birds Survey. More information on the design of this survey and the methodology can be found here: http://www.bto.org/volunteer-surveys/bbs/research-conservation/methodology
SNH produce an Official Statistics bulletin and the accompanying summary data in PDF form.
This National Outcome Indicator describes changes in the numbers of breeding birds in Scotland. Birds can respond relatively quickly to variations in habitat quality, through changes in breeding output, survival or dispersal. Since most bird species are relatively easy to identify and count, geographically widespread, abundant and diurnal, birds are often used as indicators of environmental change. A target has been set to increase the abundance of terrestrial breeding birds.
The index is updated annually (usually in November) - the data are 11 months in arrears.
This slice of multidimensional data is not a Linked Data resource in the database: it's a virtual resource (i.e. you can't query it by SPARQL). But does have a permanent unique URL which can be bookmarked.
