Tree Sparrows at Jayhouse Lane

Les Midgely reports the following. At least three families of Sparrows are around the area. The only definite boxes he saw used were; the one on a telegraph post and one on a gatepost. The birds appear to use both boxes with no problems. He looked again yesterday (28th) and some birds seem to be about to start a second brood in boxes as they are taking in nesting material. Les also asked me to mention that the birds now seem to range over a much larger area along Jayhouse Lane than he remembers in the past, increasing population perhaps ?
