Starlings.
Noisy and sociable they're a common sight in our gardens. And what with the huge flocks seen in some parts at this time of year, you'd be forgiven for thinking that starlings are doing rather well.
This however masks the truth that the UK population has halved since 1995. Released today, the annual 'State of the UK's Birds' reveals the fortunes of our birds, both in the UK and its overseas territories.
So here's a picture of some starlings in the snow. Despite the loss of half the population, you can help. One of the reasons for decline is lack of nest sites, so helping can be as simple as putting up a starling nest box.
This is one of thousands of wonderful nature images from RSPB images. Take a look and find one that makes you smile this Monday.
