Atlas on TV

On Inside Out West this Friday 7.30 Mike Dilger will be shown doing ST47 tetrad G for the Atlas (Gordano valley). Filming was last autumn.

One or two questions have been raised about Breeding status definitions. This mainly concerns the difference between T for teritory and P for pair in nesting habitat. Both these give probable breeder status, and are better than simply S for singing male. Two males singing against each other can also count as T, and N , for visiting probable nest site can be used for Jackdaws investigating Chimneys for instance. D is any sort of courtship or display, and either D or T would cover fighting males. But the object is to get confirmed breeding status for as many species as possible, which will be easier once birds start feeding their young.
