I've found, before, that younger children can't manage anything like this long but enjoy joining in for a few minutes. We've tended to do the Birdwatch from inside to prevent little people scaring away birds and animals.
Last year, the questions weren't just about birds but other wildlife too.
The Birdwatch, this year, is from 25th-26th January. We are hoping to watch on 25th. Our results this year might be a bit skewed by these little creatures who don't believe in protecting birds.
Despite this, we saw a Greater Spotted Woodpecker just a few days ago, in our garden. Somehow, I doubt that will happen on the day of the survey.
Have a happy time looking for birds in the garden.
