If you came to this Derbyshire spot in winter, with all its down-at-heel problems of congested traffic, air pollution, dense housing and largely garden-free conditions, the bottom of Fairfield Road would be about the last place in Buxton you’d imagine to find breeding house martins. Yet it is about the only place in town with a good-sized colony of these exquisite if declining summer migrants, so unpicking why they have persisted here and gone almost everywhere else locally is instructive.
One element may be the height of the terrace housing. The buildings are on three floors and the overhanging eaves, where martins locate their mud-cup nests, are beyond the reach of “tidy-minded” souls worried about droppings below. A more certain factor is that the back of Fairfield is only a house martin’s swoop away from what was once the town tip called Hogshaw. Yet in the last half-century it has been redeemed by nature and smothered in sallow and birch woodland. Those two are among our most insect-friendly tree species, and the resulting abundance of invertebrates which not only accounts for the birds’ presence here, but determines almost everything about house martins.
