Here in the UK, it is 'Big Garden Birdwatch' weekend - an annual event organised by the RSPB (Royal Society for the Protection of Birds).
Gardeners are asked to devote just one hour over the weekend to monitor their 'bird-visitors'; feedback helps to ascertain trends in garden bird population.
We go one better and monitor birds all year round, using a bird-spotting chart I devised about four years ago. Results are quite significant and very weather-dependent. You can see our completed chart for 2008, and a photo of our bird-feeding station in my gardening blog. Click on the link just given; it will take you to my website; all you then need to do is to click on the 'blog' heading. I have included the web address of the RSPB in my website-blog post for today, in case UK followers would like to become involved.
I painted the little Robin watercolours in around 2001; no initial drawing, a paint wash straight on the page. From the look of them, I guess they may have been one of my challenges to myself to paint with my left hand; they are certainly rather wobbly!
