Commas, Commas, Commas.

Garden at Dempsey Towers absolutely rammed with Commas this afternoon on this "Summer in September Saturday".
Usually get one or two in autumn, but five gorging on Michaelmas Daisies with Red Admirals, Small Torts and Large Whites, and more in the Leylandii and Ivy.

Raggedy and wonderful, but I think I might swap one or two for a Yellow Browed Warbler - with the east coast sinking under the weight of them, surely a few must filter through to us any time now.
Eyes to the skies everyone, eyes to the skies...

During the last few decades, the population of House Sparrows has declined by roughly half, causing great alarm amongst both scientists and the general public. However, the latest data from the British Trust for Ornithology’s (BTO) Garden BirdWatch, suggests that the decline is levelling off in our gardens.
The decline of the House Sparrow has been dramatic, falling from around 12 million British pairs in the 1970s to between six and seven million pairs currently, with a greater reduction in population size in urban and rural areas, than in suburban ones. Given that gardens are thought to be a particularly valuable habitat for our House Sparrows, it is encouraging that the latest BTO Garden BirdWatch data indicate that numbers are stabilising, which is also reflected in data from the wider countryside.
The reasons behind the decline very much depend on population location, as House Sparrows are fairly sedentary birds. Populations across Britain were affected by loss of nesting sites and food sources, especially the lack of invertebrates to feed their young. However, in rural areas, changes in farming practices are thought to have had a large effect but in urban and suburban populations causes were more complex and may have included increased competition with other birds and increased pesticide use in gardens.

Lots of Chiffchaffs moving through Coronation Park, Ormskirk this week, there has also been a single Barnacle Goose in with a flock of Canada Geese.
