Tarifa

I’m in Tarifa. Tarifa is the southernmost point in Europe – or at least the point closest to Africa or something – which is why I’m here. Migration. Huge flocks of raptors flying across the straits on their way north. Theoretically. It’s also the kite-surfing capital of Europe, so if I suddenly get the urge to get a tattoo or a pair of baggy shorts, I’m in the right place.

The kite-surfing thing is because of the wind system created by the meeting of the Med and the Atlantic. So I may also end up a bit sand-blasted.

El Rocio

OK, I can’t get to my hotel because there’s a procession in the way, which seems like a good opportunity to blog the first week of my trip. Or to go to a bar and have a beer and a little tapa of something, but blogging it is.

I went to a town on the borders of the Coto Doñana National Park called El Rocio. Next to the town there’s a huge lagoon called Madre de las Marismas (mother of the marshes) where there are lots of birds, and there are some convenient other birding spots nearby, including a mix of habitats: pinewoods, scrub, deciduous trees along the rivers. So it’s a good place for birding on foot. I did pretty well on the bird front, getting most of the things I would have said were target species – Azure-winged Magpie, Great-spotted Cuckoo, Purple Heron – as well as some rather less glamorous lifers like Great Reed Warbler. Oh, and flamingo, spoonbill, stork and so on. So that was good. I hope I’ve got some quite nice birdy photos out of it, but those may have to wait until I get back to my own computer before you see them.

It also had enormous numbers of nightingales. Really a lot. I got quite annoyed with them after a while, because I rather hoped one would be a Penduline Tit or something. Nightingales are famous for the beauty of their song, or course, but actually I think they’re really famous because they’re very loud and completely indefatigable. Not only do they sing at night, they sing all day as well, absolutely belting it out. They do make some quite nice noises, to be fair – including Coleridge’s ‘one low piping sound more sweet than all’ – but they also make some very peculiar squawks, rattles, grunts and so on.

El Roco is quite an interesting place – all one-storey white buildings and sand-covered roads. Very pictureskew. All the guidebooks accuse it of looking like the set of a cowboy film. On the other hand, after a long day on your feet, carrying a telescope, birdbook, water, binoculars, camera, suncream etc, walking on sand really saps the strength out of you. The locals get around on horses, dirtbikes or 4-wheel drive.

El Rocio’s other claim to fame is that it’s the site of Spain’s biggest annual pilgrimage. A million people come, apparently, many on horseback or in oxcarts, and much piety, drinking, eating and generally debauching around the campfire ensues. In flamenco costumes. So there are whole streets of buildings marked with ‘Hermandad de Sevilla’ or whatever – a different brotherhood for every town in Andalucía. There must be hundreds of them and, of course, they’re all empty for the 51 weeks of the year when they’re not hosting pilgrims.

Anyway, I was mostly birding and I won’t bore you with too many details about that. I’ve now been in Seville for a day and a bit, but I think that my Seville thoughts can wait for a moment.

… and annoyingly I haven’t brought out my bit of paper with email addresses on it, so I can’t email my friends and family. Oh well, that too will have to wait.

After 200 million years of abstinence…

An interesting story about darwinulids. As far as anyone could tell, darwinulids (a type of crustacean) had been reproducing exclusively asexually for 200,000,000 years, but now a researcher has found 3 male specimens, which implies that at least one darwinulid species has sex.

Sex is a bit mysterious in evolutionary terms because it’s so much more efficient to reproduce asexually. Quite apart from the time-consuming business of finding a mate, sexual reproduction needs twice as many adults to produce the same number of offspring, and when you do breed, only half your own genes end up in the child anyway. That’s a huge reproductive disadvantage; yet pretty much all animals have sex. So it must offer some kind of dramatic short-term advantage to compensate for that reduced breeding rate. Even animals like aphids, which mainly breed asexually (aphids are born pregnant!) occasionally produce a few males and breed sexually as well.

The most popular theory is apparently that it helps fight disease and parasites – read The Red Queen by Matt Ridley for the details – but certainly its omnipresence implies that sex serves some kind of vital role. Which makes it hard to explain the few groups of animals that seem to have been merrily getting along without for tens of millions of years. If it is confirmed that darwinulids have been secretly shagging away somewhere all along, it removes an anomaly. That still leaves the marvellously named bdelloid rotifers, who have apparently been holding out for 40,000,000 years.

Government ‘harassment’

I came across an animal liberation website which stated that “government harassment of activists has continued to increase this year”. Harassment in this case seemed to mainly consist of people being convicted of arson, criminal damage, blackmail and so on. Describing that as ‘harassment’ just seems so… whiny. Sometimes it’s right to decide that you know better than the law, and that the claims of morality are more important. But if you’re going to knowingly break the law in support of what you believe is a noble cause, you can hardly claim ‘harassment’ when the criminal justice system does its thing.

I also find the focus on animal testing peculiar since, for me, the hundreds of milions of chickens raised intensively every year are a much bigger animal welfare issue than the two or three million animals used in testing.

FWIW: I support suitably regulated animal testing and eat meat, but I do try and only buy organically-raised chicken and pork.

Sparrowhawk

I was absently looking out the window and realised that a bit of a kerfuffle was a sparrowhawk taking one of the pigeons. Female this time, so she’s bigger and browner than the last s/hawk in the garden. By the time I had my scope and camera ready, she dragged the pigeon behind a bush, so she was obcured and the light wasn’t great. But at least the photo is good enough to show she was there.

The cat scared her away before she’d finished, and the pigeon flew away too, so there’s a partially plucked pigeon out there somewhere. A pigeon is quite large prey for a sparrowhawk, which is presumably why she didn’t take it very far.

Atheism again

I said a few posts ago, about my own atheism, “I don’t believe in unicorns either, but I’m not about to go to any meetings about it.” Well, I haven’t been going to any atheist meetings, but I have been reading the comment threads at Pharyngula, which is a pretty good internet equivalent.

My own stance on evolution and religion is hard-line: I think the evidence for evolution is overwhelming, that anyone who doesn’t accept it is just plain wrong, and that standard compromise of evolution being somehow guided by God is just a muddle-headed cop-out. I get as angry as the next atheist at attempts to get creationism/ID taught in biology lessons. And as a social liberal, I don’t have much time for Christian fundamentalism in any circumstance, and I’ve done my fair share of internet Christian-baiting.

And yet, despite my own intellectual intolerance and the fact I share all the biases of the commenters at Pharyngula, I still find the atmosphere there toxic. There’s so much energy being expended on hostility and derision, such a sense of superiority on display. Anyone who rejects evolution – or believes in God, really – must obviously be an idiot or a liar. There’s not even an attempt to empathise with anyone who values faith over reason.

I don’t know. Maybe I’m getting soft. Or maybe I just recognise my own worse qualities in the people there. I should probably say, to be fair, that not everyone there matches the description I’ve just given. Perhaps no-one does, really; but that’s the overall tone of the site. And I should also point out the endless provocation from the anti-evolution people. But still. I’m tempted to say that I think it’s bad strategy, that they’re alienating more people than they’re persuading, but I have no idea. What I do think is that, for want of a less spiritually loaded term, it’s just bad karma.
