Wire-Tailed Swallows spotted at the Basai Wetland, Gurgaon

Today when I decided to visit the Basai Wetland in the morning, the lighting was awful. Nevertheless, I managed to capture a couple of wire-tailed swallows having a quiet time together. When I looked at the photographs later on, I was surprised to notice what looked like two strings trailing from one of the birds' tail. Initially, I wondered if this might not have been a thread from one of the nets used for catching fish. On looking closely, I realised that these were in fact long hair growing out of the tails. No wonder they looked strange, but then these were birds that I had seen flitting in the sky but not sitting in one place.
