We had some brief visits by a pair of martins yesterday. They clung on the wall at the site of one of last year’s nests which fell down in the winter on a night when the temperature dropped to -15 celsius. At the time the nest was full of roosting Wrens. They may well build another nest here but I have provided six artificial martin nest boxes to compensate especially as mud is very hard to find in this exceptionally dry spring. These martins arrived just two days earlier than the first last year.
