House sparrow explosion

House sparrows have been fairly regular visitors to our garden. We see them all year round, with an average number of 3 per observation day. But in the last few weeks the sparrow population in our garden seems to have exploded. Before September this year, the most we’ve seen at one time was 9. Now there are more than I can count (they keep moving!).

They’ve been hanging around our garden quite a bit, and getting through the bird seed faster than I’ve ever seen before. I’ve no idea why we have had the sudden increase. In previous years there hasn’t been a large increase in numbers around this time of year.  Perhaps they’ve had a particularly good breeding year?

They’re not the most spectacular of birds, but it’s great to see so many of them, as their numbers have plummeted in recent years. In the 1970s there were around 12 million pairs in the UK. Now there are between 6-7 million pairs. The good news is, data from the British Trust for Ornithology suggests that the decline has stabilised. Now we just need to work out how to help them recover.

Earlier this year we installed a sparrow terrace (to try and tempt them away from our gutters as a nest site). The boxes weren’t used this year, but hopefully some of our new visitors will decide they’re a good nest spot for next year. I’ll let you know!

Have you noticed anything similar in your garden?
