Comment Re:Farmers will be delighted... (Score 1) 108

Passenger pigeons were not primarily a grain species, although they would eat grain when other preferred foods were in short supply. Part of the reasons the flocks increasingly turned to grain with time is due to the cutting and burning of many of their native forests to make room for farmland (and with an average lifespan in captivity of 15 years, probably half that in the wild, populations don't readjust right away). They were a migratory species, of course, but the habitat destruction was going on all over their range. If you get rid of the oaks and chestnuts in an area and the only other food option is grain, of course they're going to eat that. They also ate insects, mainly when breeding.

When you're talking about reintroducing a species from scratch, obviously the issues of what to do if a billion birds come into the area is totally inapplicable. The forests capable of supporting those numbers are gone. Birds that primarily consume seeds and grains are a much bigger threat to farmers than birds with a primary focus on nuts like the passenger pigeon.

it would take years for the ground plants to recover

Citation needed. Bird manure is one of the best natural fertilizers in existence. Have you seen what people charge for chicken manure? It's outrageous. Now, it's a concentrated enough fertilizer that you have to use it more like a chemical fertilizer than a soil suppliment - so it's possible that the pigeons would "nutrient burn" a location. But that's short term, in the long term that means leaving the area incredibly lush. And not to mention full of seeds in their droppings.

Trees and many smaller plants primarily cater to birds as their seed distributors.

Passenger pigeons mainly ate tree nuts, particularly acorns, for most of the year. So they had a big effect on controlling tree distribution - in particular red oak has taken over from white oak after their demise in their former habitats (white oak is a slightly more valuable timber tree, FYI). During the summer they would also eat berries. They would sometimes steal grain from farmers but it wasn't a main part of their diet. They additionally consumed insects such as caterpillars and snails, so they did some good for farmers as well.

FYI, honeybees aren't native to the US. And colony populations are totally artificial, as people can raise as many colonies as they want, queens are mass-raised (you can mail order them) and the only limiting factor on the number of honeybees is the number of hives raised by beekeepers. Colony losses are a financial hit to beekepers but they're no threat to the species or the usage of honey bees for pollination (only the economics of their usage). And the increase in the rate of colony loss is way overplayed.

There were humans living alongside the passenger pigeon for thousands of years before European settlers arrived.

Anyway, this "readapting" of an ecosystem isn't necessarily a good thing. For example, the extinction of the Carolina Parakeet (the only parrot native to the eastern US) coincided with major spreading cockleburs in the US, as it was a major part of their diet. Are you a fan of cockleburs?

It was on the BBC news this morning, which probably counts as more reliable than 4chan. Most interesting was the claim by one of the women involved that the photos had been deleted. If this is true, then it would be a great example of the fact that just because something is 'deleted' in the cloud doesn't mean that malicious people can't get at it in the future...

If I'm going to report errors in a map, I'd rather do so with a map that releases its data under a license that allows reuse. Since such a map already exists and doesn't have the errors in Google Maps, I don't see much incentive. Google can pull the data from there if they want. This is actually one case where Microsoft has been a bit nicer: they allowed OSM to trace their satellite images to improve maps. Google Maps, in contrast, is very protective over their data.

If it's so reasonable to "transliterate foreign proper names", then why is it that they only seem to do it with countries like Iceland? They don't usually transliterate proper names from other countries - for example, German (Düsseldorf) or France (Équipe FLN), just to pick a few quick examples.

The Met Office's decisions have all been perfectly cogent, it's only the poor reporting that's led to confusion from lay people.

In the first case there were all signs of an eruption under the glacier. They issued an alert. Later there were no signs on the surface, so they removed it. Later on, glacial subsidence proved that an eruption had indeed taken place, but stopped. In both cases, correct behavior on their part.

Then there was the 1st Holuhraun eruption. When an eruption begins, theres no way to know how its going to evolve, but since it was just a lava eruption, it was only restricted on instrument-only flight and only to 5000 feet. When it died down, they removed it. Again, right call by the Met Office.

Then there was the 2nd Holuhraun eruption. Again, 5000 foot instrument-only restriction, and when it steadied out, they removed the restriction (yes, the Slashdot article is wrong, the restriction has long been removed). Again, right call by the Met Office.

People need to stop armchair quarterbacking, they're doing the right thing.

Or for an English example volcano, "Yellowstone" (11 letters).

To an Icelandic speaker who knows the component words, it's obvious where they split. Eyja (of islands) Fjalla (of mountains) Jökull (glacier), easy as pie. Their brain automatically cues into the "a"s as context clues for splits to make it even easier.

But picture a person who doesn't speak English at all who sees yellowstone. So they don't know the word "yellow" and they don't know the word "stone". Nor do they know what letter clusters are common together in English - or example, "st" - and which ones are not - for example, "ws". To them it'd be just the same thing, they don't see where to split it, and thus the word looks like a jumble of letters.

I don't know about rural Japan, but I found the OSM data far better when I visited Tokyo a few months ago. Google didn't know building names and placed a load of things that we were trying to visit a few blocks away from where they actually were. This was very frustrating as the web site that we were using to find vegetarian restaurants used Google maps - we spent half an hour one lunchtime walking in the wrong direction, because we'd come to a junction and, according to the Google map needed to turn left and would then see our destination on the right. It turned out, when we eventually found it, that we should have turned right.

I use OSMAnd on my phone[1], but my girlfriend recently bought a Windows Phone and I've been very impressed with Nokia's mapping app (I actually like a lot of what Microsoft's done with Windows Phone 8, but it's a strange mix of very polished and well-designed UI parts and completely unfinished parts with missing features). It's good to see more competition with Google maps, which is becoming increasingly entrenched in spite of the fact that the UI is pretty poor in many regards and the mapping data is terrible. For example, here they're missing (or have in the wrong places) most of the cycle paths, which ends up with people regularly getting lost if they rely on Google, in spite of the fact that all of this data is in OpenStreetMap.

[1] For me, it's the killer app for Android. Offline maps, offline routing, and open source backed by high-quality mapping data from OpenStreetMap. I use the version from the F-Droid store, which doesn't have the limitations of the free version from Google Play and it's one of the few open source apps that I've donated money to.
