Un-American Activities

In case anyone was wondering what was behind the statement on the LROS Bird News page yesterday regarding a reported American Golden Plover at Cossington Meadows, here is a short version of the story.

Basically, the ‘observer’ who reported the plover is known to have claimed a lot of highly unlikely birds in the county recently. I thought Birdguides at least were aware of him, but this one slipped through the net somehow. Unfortunately I didn’t find out who it was until after dark, by which time a lot of people had wasted an afternoon looking for a non-existent bird.

Although I’ve never met him, he has been described to me as a ‘very keen but over-enthusiastic young lad’. I’m not sure how young, but certainly old enough to be able to use a computer and report sightings to Birdguides and LROS. I would also suggest, particularly in view of the fact that he has been warned about reporting fictitious rare birds before, not least by his parents, that he ought to be old enough to realise the possible consequences of his actions.

Before anyone asks, given his previous claims I don't think there is any possibility that he simply ‘made a mistake’ with this bird. It’s not certain that he was even at Cossington Meadows yesterday as about ten later ‘updates’ on the bird in the afternoon all appeared to have been sent from a home computer, along with a later report of a White-billed Diver at the site and a Red-flanked Bluetail & 2 Black-necked Grebes at Priory Water around the same time. And that wasn’t his first Red-flanked Bluetail in the county this autumn.

Over-enthusiasm is one thing, but this seems to be crossing the line into out and out fabrication. All very unfortunate, and sadly symptomatic of our modern rarity-obsessed birding culture. As John Hague pointed out, when we were that age (whatever age he is) we wouldn’t have even heard of birds like Red-flanked Bluetail, let alone thought that we might see one. We can only hope that he will grow out of this and go on to become a proper birder, although I’m afraid it will be a long time before anyone believes anything he reports!

Hoax!

Yet again there’s a thread in progress on Birdforum about an apparent hoax – this time an anonymous Twitter report of an Eyebrowed Thrush in a private garden at Hunstanton last weekend. I have to say that on the evidence available so far this one is looking like a hoax, but some of the arguments regularly trotted out on BF on these threads are somewhat spurious, to say the least. In particular a lot of people seem to have become fixated on ‘EXIF data’ whenever a photo of a contentious bird appears. Look at the EXIF data – that proves it’s a hoax. Someone’s removed the EXIF data – must be a hoax. No, it’s gen – the EXIF data fits with the claimed time of the sighting. Etc, etc.

OK, if the bird was claimed to have been seen at a particular time and the EXIF data is completely at odds with this (weeks or months out), then yes, be suspicious, but it doesn’t prove anything on its own. Many cameras will have incorrect times and dates – I just checked mine for the first time since I first set it up nearly three years ago, and although the date was right, the time was an hour and fifteen minutes ahead! Doesn’t say much for the clock chips Canon use. EXIF data can also easily be edited using various free programs, so even if it does fit with the claimed time and date of a sighting it’s completely irrelevant as evidence to support a claim.

But what about a total lack of EXIF data, as is the case with the Eyebrowed Thrush photo? Anyone who knows even a little bit about web design should be aware that photos should ideally be ‘saved for web’ to minimise browser loading times. This is even more important these days with so many people using mobile devices to browse the Internet. Obviously the majority of people don’t know this, which is why you see so many HUGE photos around that take forever to download on a phone. And many photos saved at low jpeg settings, which consequently look a lot worse than they would if they were properly optimized. But people who do know what they’re doing save everything for web in Photoshop. As well as optimizing the image so you get the best possible quality whilst keeping the file size small, this also completely removes the EXIF data. There is absolutely nothing sinister or suspicious about this – in fact in an ideal world it would be normal practice for anyone uploading photos to the web.

If you look at any photo of mine anywhere on the Internet (flickr, LROS website, this blog etc) you will not see any EXIF data, and the date shown will be the date I saved the file (which could be months later), not when the photo was taken.* Does that mean I’m a hoaxer? Well, I was in Hunstanton on Sunday......

* - a perfect example of this is the first Humming-bird Hawk-moth photo on my flickr page - it says authoritatively: 'This photo was taken on November 6th 2011'. No, it wasn't - it was taken on September 27th 2011, but because there's no EXIF data, flickr gives this completely spurious date, which is just the date the file was created. As far as I know there's no way of turning this off - if I could, I would.

Facebook

This may come as a shock to some people, but I've finally given in and joined Facebook. It seems to be the thing to do these days. So if you know me, you may be getting/have already been sent an invitation to be my friend. This always sounds a bit pathetic and needy to me, but that's what they decided to call it, so who am I to argue. So pleeeease be my friend..... oh, go on....... I'm really not as objectionable as I seem...... I promise I won't keep ringing you up, or emailing you hundreds of amusing pictures of cats, honest......

At some stage, when I get my head round it all, I shall be creating pages on the aforementioned social networking site for my two art websites. I know most of the people who read this crap aren't likely to become customers for artwork, but the point is that friends of friends, or relatives of friends, or friends of relatives might. Sort of like viral, innit. In the modern parlance. I'm dead modern, me. I'm on Twitter as well, you know.

More Shameless Self-promotion

As I may have mentioned a while back, I've been intending for a long time to create a separate website for my pet portraits. After a lot of messing about, it's now live, so in the interests of getting at least one in-coming link to it, here it is:



Feel free to link to it, share it, Tweet it, like it on Facebook etc.

Religious Persecution by Mustelids?

This could easily have been Photoshopped, but I swear this is a genuine screengrab from the BBC's Nature UK page (http://www.bbc.co.uk/nature/uk/) today. No doubt it will have disappeared by Monday.
