Just out of interest, why is it 'serious'? Because it is according to the stats and certainly in my part of south london we are noticing serious declines in sparrows, five, ten years ago there were hundreds I'm sure, now we are lucky to see a handful each day, as for thrush, blackbird etc none for ages. I see many birds now that I never saw as a kid, including (perhaps not coincidentally) many species of raptors and numerous magpies. If a part of the decline is due to that, and another part due to us not having sparrows living in our house roofs, and a further part due to farmers not feeding them by scattering grain all over the fields when harvesting, then you could reasonably argue that the sparrow pop of (say) 1900-1950 was artificially boosted over what it would be in an environment with no human interference, since there would be far fewer artificial (i.e. houses) nesting sites , much less food, and many more predators, in such an environment. Maybe the 'natural' sparrow pop is closer to what it is now, than it was 50 years ago? You make a very good point. This is why it would be nice to see some of our RSPB funding spent on serious research so that we may have a definitive answer. I feel this is a bit more than the natural yoyo cycle of populations. |

Tim Lamb writes
Improved hygiene requirements for the storage of food on farms both for animal and human consumption has eliminated this food source. Remember the seriously improved hygiene AND TIDINESS is imposed on farms by supermarket diktat. Obviously the less grain lying about the fewer birds and the fewer small rodents. -- Oz This post is worth absolutely nothing and is probably fallacious. DEMON address no longer in use. |

Faecal samples taken and analysed, both from the chicks and from droppings of the adults, scraped from my windowsills. Vegetation in gardens regularly examined for invertebrates, samples taken from hedges, trees, bushes and plants. Newsletters produced and distributed to participants and regular phone and email contact for matters of interest relating to sparrows and all this over three years. And more I don't know about, no doubt. I would suggest that this would take plenty of funding and I say well done all who funded it. RSPB/BTO etc. And well done to Kate who cares about sparrow's decline. Tina You would appear to be missing the point. Yes, kate is doing a grand job, no one claimed otherwise. The RSPB however are offering lip service to a very serious problem, this should be a national, scientific, peer reviewed study on a grand scale, we've certainly paid for it an without it the results are meaningless. this SHOULD have been done five, ten years ago. Lets hope it's not too late, certainly if we waited for the RSPB to dip into their pockets it will be. The RSPB have managed to raise over £5 million pounds to fund a ruddy duck cull that no body wants except a few twitchers obsessed with their own self importance. Surely they could put as much effort into raising the same kind of over funding for the decline in sparrows etc? Regardless it comes from RSPB coffers or tax payer, the RSPB can do it and yet have done nothing! In the meantime whilst we all wait around for them to do something, because we expect them to do something and that's what they are there for, the declines are looking pretty serious and some are talking of extinctions! You might be gullible enough to consider kate is the savior of the sparrow and nothing else needs doing. I'm not. |

After a month of two of arriving in a beat up car, she came in an RSPB van, with a helper for the hardest summer work from the RSPB. Dr Peach from RSPB came and clambered into my loft via the bathroom door the first year to see the sparrows under the eaves, and advise Kate how to go about studying them. So, yes, the RSPB are spending money on this.. And as I mentioned just a few days ago, see the house sparrows here studied for 3 years by Kate, filmed by the RSPB. (soon) Get the video (or it might be on TV, .not sure yet.) Have you even read the page at that url? It's now 2004 you know! |

(One year we got 26 inches of snow and it stayed for weeks). There were always coveys of hill grey partridges pecking around where the cattle were fed on oats on the sheaf (unthreshed) over winter. Then my neighbours gradually put up buildings and kept their cattle inside over winter and they hired a combine rather than using a binder to harvest the oats. Result? The partridges disappeared and the grouse declined. Most of these farms, and the lower parts of the grouse moors, have now been planted up for forestry to grow trees nobody wants. I have too many sparrows here (40 miles north of Inverness), but then my buildings are dilapidated and the free range hens are on a self feeder. Derry |
