The mammals you'll see in this quiz are all on the Red List for Britain's Mammals: Red List for Britain’s Mammals – The Mammal Society.

When you click "Start spotting", you will be shown a set of 8 image sequences or videos to classify.  Use the species lists provided to classify the species captured in the images.  At the end, you will be shown your score for agreement with our 'experts', as well as the sequences on which you agreed or disagreed with the experts. 

Remember: sequences devoid of wildlife are an inescapable reality for camera trappers, so don't assume that every image contains a species of interest.  Otherwise, all sequences should contain a wild or domestic mammal found in the UK.  If they don't, please let us know ... even experts are wrong some of the time - so use the "Challenge" button on the Results screen to flag up possible errors!  Note that some sequences might contain more than one species; you will need to identify all species pictured to get the classification correct - even if the other species is a bird!

Scientific name: Corvus albus

Appearance: Large, black crow with white chest and collar.

Natural history: Often occurs in flocks, roosts communally.

Any representative of the many and varied breeds of domestic animal kept principally for production purposes, including cattle, sheep, pigs and goats.

Remember: sequences devoid of wildlife are an inescapable reality for camera trappers, so don't assume that every image contains a species of interest.  Otherwise, all sequences should contain a wildcat, wildcat-domestic hybrid, or domestic cat.  If they don't, please let us know ... even experts are wrong some of the time - so use the "Challenge" button on the Results screen to flag up possible errors!

As you might be aware, wildcats are greatly affected by genetic introgression (i.e., genes introduced from breeding with domestic cats, leading to a loss of those genes that adapted wildcats for life in the wild and gave them their characteristic appearance).  Cats affected by hybridisation are highly variable in their colouration: some that are quite pure wild cats look very unlike wildcats, owing to small numbers of genes that have a big effect on colouration; some cats that carry many domestic cat genes can actually appear very like wildcats.  Consequently, identification based on coat patterns is a very inexact science.  Here, being 'right' or 'wrong' merely indicates how close you got to the cautious designation of the Scottish Wildcat Action team, based on classic indicators of wildcat appearance.
