House Martins have returned over the last couple of days with at least two pairs holding disused nests on our house. I am baffled as to why they are showing such interest in the nests this late. Two pairs returned in late spring but both failed to raise young and had deserted by early July. With the adult birds are many juveniles so we are currently treated to between 20- 30 martins wheeling around the eaves in the morning. Whilst it is highly unlikely that either pair will attempt to breed this late, it is certainly wonderful to have martins around again and perhaps this late prospecting bodes well for us next year.
