National Nest Box Week runs each year from 14-21 February.
Natural nest sites are disappearing fast, therefore BTO are encouraging people to put up nest boxes in their gardens to help breeding birds.
In my garden we have 12 nest boxes, which recently we took down to clean and maintain before putting them back up again.
This year I have numbered each of the boxes and will hopefully keep a record of what nests in each one, and which areas of my garden are most successful.
While we were cleaning them out we came across a dead House sparrow.
