Some House Martins started to build a nest on our house on 1st June and finished on 12th June. This was a dry period of weather so I had to top up the puddle, where they collected the mud pellets, on a daily basis. Here is how they did it.The end product on 12th June! The nest was constructed by both birds. Some photographs show the darker mud which is still damp.These bands indicate a day’s work.
