Meadow Browns are very common on London grasslands and, as the name suggests, could easily be taken for moths.

It is 'world earth day today', so its important to keep reminding ourselves that every little thing we can do to help nature/ and environment is a step forward to improving our own lives too. With the decline of so many creatures like hedgehogs 36.5 million now down to only 1.55 million, 'world earth day' is happening all over the world to make everyone more aware of how we can all make a change, no matter how small.

Great spring walk on Green Dale and through Dog Kennel Hill Wood this morning, led by Daniel Greenwood of the London Wildlife Trust. The good news is that the whitethroats are back from Africa ? and even better news is that we heard a lesser whitethroat too. That's a first for me around here.
goldfinches in my garden eating the seeds from the dandelion clocks that I've been remiss in removing- and may very well let them grow now (however, if the goldfinches eat the seeds there won't be many dandelions ...). The clever birds push the stalk down with their foot and then eat the seeds and the fluffy bit blows away

Yes indeed :-) Just heard their 'scream' near Dulwich Hospital. Here are the return dates as reported here for the last seven years:


2011 ? May 9

2012 ? May 1

2013 ? May 17

2014 ? May 8

2015 ? May 9

2016 ? May 4

2017 - May 6


I checked the weather for 2013 and it turns out there were persistent cold northerlies throughout the end of April and early May, which must have held them back. Not unlike the last couple of weeks this year, but it's great to have them back.

Had an enjoyable dawn chorus walk around Green Dale fields this morning. Many thanks to all who came and listened. We heard and/or saw robin, blackbird, wren, great tit, blue tit, goldfinch, chiffchaff, blackcap, song thrush, mistle thrush, carrion crow, herring gull, greenfinch, wood pigeon, dunnock, ring-necked parakeet, magpie, house sparrow and possibly more, though I'm rather tired...
Listened to BBC R4 Dawn Chorus last night, a lovely idea... I was also delighted to see the swifts were back yesterday, especially reading the article in the Guardian that said London hadn't had them for ten years https://www.theguardian.com/commentisfree/2017/may/05/common-swift-silent-summer-birds-habitat-loss-farming#comment-98011472

That's very interesting BrandNewGuy. Do you see many peregrine falcons in the area?


I meant to say thank you very much for collating the dates of the arrival of the swifts. It astonishes me how punctual they are. I suppose they must be sensitive to day length? Though some of their wintering grounds won't have much yearly variation in hours of daylight. But I believe some migrate from as far as South Africa? Almost unbelievable. I understand it was a great conundrum to Victorian naturalists as to where they went in the winter.


As to what people say about reduced numbers. Yes - I've noticed that too. Let's just hope the decline can be reversed. Is lack of nesting sites the main problem? The loss of the old hospital onion towers probably removed one site.

    • You literally just edited your earlier reply to remove the point you made about it being “politicians”.  Then you call me pathetic.    I’m  not trying to say you approve any of the ugly right wing nonsense.  But I AM Saying your earlier post suggesting  violent rhetoric being “left wing” was one-sided and incorrect 
    • I never said that. Saying I don’t like some of the rhetoric coming from the left doesn’t mean I approve of Farage et al saying that Afghans being brought here to protect their lives and thank them for their service means there is an incalculable threat to women.    Anything to score a cheap point. It’s pretty pathetic. 
    • To be fair we are as hosed as the majority of other countries post-Covid. The problem is Labour promised way too much and leant in on the we need change and we will deliver it and it was clear to anyone with a modicum of sense that no change was going to happen quickly and actually taking the reigns may have been a massive poison- chalice. As Labour are finding to their cost - there are no easy answers.  A wealth tax seems straightforward but look how Labour have U-turned on elements of non-dom - why? Because the super rich started leaving the country in their droves and whilst we all may want them to pay more tax they already pay a big chunk already and the government saw there was a problem.
    • You don’t think there are right-wing politicians fanning this with rhetoric? Really?
