Weird Thought for the Day
Even amoebas have downtime.
Harlequin Ladybird (Harmonia axyridis)
I found this today on a rose bush in the garden; the first one I’ve seen; I’m pretty well certain of the ID. Not the best of pictures I’ve ever taken.
The Harlequin Ladybird is a recent arrival in the UK and it is spreading from the SE. It is a pest: it is aggressive, spreads quickly and predates other ladybirds rather than following their example and eating aphid. More information at www.harlequin-survey.org and www.ladybird-survey.org. Yes, I have submitted a report to the survey.
And now one has a dilemma. Do I destroy the beasticle on the basis that it is a pest, or do I let it go free rather than risk damaging my karma?
Berberis in Flower
The Berberis in our garden looking stunning in the Spring sunshine. It’s been in flower like this for at least the last week. It’s bee heaven too. You really need to see this full size on Flickr!
Parakeets under threat?
According to yesterday’s BBC news the UK’s Department for Environment Food and Rural Affairs (Defra) has commissioned a study to look at the problem (what problem?) of increasing numbers of Rose-Ringed Parakeets in Britain. There is now a large population (estimated at 30,000) of these handsome bright-green birds around the southern and western fringes of London and into Surrey with enclaves building elsewhere in the country. No-one is sure exactly how they birds arrived here, about 50-60 years ago; there are a number of competing theories none of which has been substantiated.
It seems Defra and the Royal Society for the Protection of Birds (RSPB) are worried that the parakeets will start out-competing native songbirds for food and nest sites and possibly, as their numbers increase, cause economic damage to fruit crops. However the RSPB website does admit that there is currently not a problem and that the birds have protected status; but it is reported that the RSPB is prepared to consider culling the parakeets, they say only as a very last resort.
These are wonderful, colourful and cheeky birds – albeit they can be a bit noisy and they’re not native to the UK (they come from the Himalayan foothills in India). Although I don’t see them often in my part of west London (not enough really big trees nearby, despite it is quite a green area) they do pass through my garden a handful of times a year. Personally I would be sad to see them disappear or even be culled.

Heron in the Hawthorn
The heron sitting in the top of the hawthorn tree in our garden in North Greenford a couple of days ago. He obviously had his beady eyes on my pond fish, and I can’t blame him as it was a cold winter’s day. I felt rather sorry for him having to probably go hungry tonight when he took fright at me opening the back door, but I don’t think he’d have got any fish as they were all huddled in the deepest middle part of the pond. And it was quite amusing to watch this large, rather ungainly bird, trying to balance on those small twigs whilst not getting its feet stuck with the thorns! It’s not the best photo I’ve ever taken, but the best I got: it was almost dusk and I was taking through the study window.
