Martins using 4in drainage pipes in a retaining wall as nest holes.There are about 20 holes above 10ft most of which are in use.One pair are using the steel water pipe shown in the last photo.The birds look brown rather than blue/black when viewed from above.Their colour and the use of the holes makes me want them to be sand martins.
