Sad to report two dead swallow nestlings on the floor underneath the ridge beam of my machine shed at Torrisholme. They were 3/4 grown and very vocal yesterday. The first brood fledged successfully. These two looked plump and healthy with well grown feathers, just very dead. There has been a fair bit of activity around the shed recently with about 5 adults and a lot of chattering and males vigorously chasing each other. Interestingly two birds were bringing in fresh material for a nest as I was leaving today. I was wondering if there is a lot of competition for nest sites and a stronger bird had destroyed the existing nest. Any thoughts anyone?
