Low flying quintet of House Martins

On the evening of Wednesday 11th September, as the light was fading, a quintet of House Martins were flying low over the garden and even under the eaves of the house. On Thursday 12th September in the morning as I was leaving for work, the same 5 House Martins were still flying low over the house eaves, alas I couldn't take any pictures as I had to leave for work.
