Should i clean the letterbox?

For the last 2 years our outside letterbox has been the home of two Robins. I hear they breed twice a year (and last fledged in June). So should I clean out the letterbox of their old nest or leave it for them to use again as is this year? 

  • Hi Billy, normally we would clean out nests and boxes after August time. If the Robins have used the box the last two years, they may well use it again, without it being cleaned out, but on saying that, if they have used it two years running, the chances are that they will probably nest again this year, so maybe a nice clean box for them to start with would be nice, ready for them to take in nesting materials.
