    "Broken car alarm"

    Never mind, that's an hour plus it's been going this time, car alarm theory beginning to hold more water.

    "Broken car alarm"

    https://youtu.be/f5LJlPiDb_M In Derbyshire, this morning and this afternoon, I'm beginning to think the unthinkable...

    Black-winged Cuckooshrike? Hebei

    Pretty sure on this one, just confirmation really. Found recently in a city park, Shijiazhuang, Hebei.

    Red Grouse in Peak District

    Other side of the Peaks from Glossop but Stanage Edge, particularly around Stanage Pole, is a location I've regularly had very close views of Red Grouse, it's so accessible they perhaps see more people there, are less wary than in the 'wilder' parts. Next week might be a little early for Ring...

    Derbyshire County Birding

    Black-necked Grebe at Pleasley Pit, at crack of dawn this morning. Bit different to the girl on the lilo who was swimming around the other evening!

    10 bags of dead pheasants found in Norfolk

    Well, it doesn't get more captive than being a bag. Seriously though, the figures are remarkable. Even by the reckoning of the Game and "Wildlife" Conservation Trust, 35 million pheasant are released each year, with the reported total bag being only 15 million. It'd be interesting to know what...

    Derbyshire County Birding

    Popped up for the GGS at Beeley this afternoon. Viewed from about 100yds from the triangle along on the north side of Harewood Road, fairly distant.

    Kestrels and near UV vision

    Interesting, thank you for the further reading. Looking for a consensus among the studies, it seems it is wrong to imagine kestrels accurately locate individual prey items via this visual cue, but still possible they learn to use it to identity higher densities of prey over a given area. But...

    Kestrels and near UV vision

    Apologies if this has already been covered, but I didn't see a recent post on the topic... I'm curious about the link between kestrels and the ability to see in 'near UV', that was established in a study published in Nature back in the 90's, and which was further supported by Zampiga et al in...

    Lesser Grey Shrike

    A belated and unconfirmed report of a LGS along the trail near Teversal on the 26th. Anyone know anymore?

    Should the RSPB start scanning RSPB membership cards at RSPB reserves?

    Now it's very interesting you say that because I'm able to fill you in a wee bit on how scanning at NT properties work. Each time a member is scanned in that property gains something called a 'member visit credit', which is currently worth £3.65 to that property. This comes from central funds...

    Sherwood Forest and a consortium led by the RSPB

    Yes, I've heard the rangers up there a couple of times complaining about what Natural England have asked them to do, silly things like remove rotting wood to make it look more tidy. Hopefully the RSPB with its expertise can argue a case against that sort of thing. Also, considering the <a...

    Don't Feed The Birds

    There was a study a couple of years ago which found reduced clutch sizes in woodland territories containing or nearby feeding stations, I think the species was the great tit. Certainly, more research needed. So far as the UK goes, I could supply plenty of anecdotal evidence to suggest species...

    Crow catches Large Fish

    Hi Brian, glad you enjoyed the action. In the wildlife centre we watched for the rest of the afternoon, by the end the two crows had only gotten through about half the fish. It looked like a pair to me, they closely associated, weren't territorial, but typically for crows wouldn't actually...
