Birds range in size from the tiny hummingbirds to the huge Ostrich and Emu. Although most birds are characterised by flight, the ratites are flightless, and several other species, particularly on islands, lost this ability. Flightless birds include the penguins, Ostrich, kiwis, and the extinct Dodo. Flightless species are vulnerable to extinction when humans or the mammals they introduce arrive in their habitat, for example the Great Auk, flightless rails, and the moa of New Zealand. Birds are a very differentiated class, with some feeding on nectar, seeds, insects, rodents, fish, carrion, or other birds. Most birds are diurnal, or active during the day. Some birds, such as the owls and nightjars are nocturnal or crepuscular (active during twilight hours). Many birds migrate long distances to utilize marginal habitats (e.g., Arctic Tern) while others spend almost all their time at sea (e.g. the Wandering Albatross). Common characteristics of birds are the ability to fly using feathered wings, a bony beak with no teeth, the laying of hard-shelled eggs, high metabolic rate, and a light but strong skeleton. Birds are among the most extensively studied animal groups, with hundreds of academic journals devoted to their study.

San Francisco got their ass kicked
Ouch Well, San Francisco got their ass kicked. Hard. Pretty much what I expected, but I didn't think it would be that bad. Oh, well. At least the Raiders won.
Woohoo that's great,
Woohoo indeed. This new initiative (registration required, sorry) for NASA might do a lot of good. But, please, NASA, please don't fuck this one up. And as for the US becoming scarce in engineers, I plan on majoring in aerospace engineering at college (wow, I start that later this year).

Larson's General Tip,
Larson's General Tip,
If the picture down there is too big, and the words go off the edge of your current browser size, tough shit. Maximize it. If your resolution is too low to allow for the entire page to be seen, make it higher. If you can't see anything except at 800x600, well, too bad. I'll take the loss of readership from the almost-blind. I have better things to do than worry about resizing the image and uploading it and altering code. Much easier to write out this yelling at you. Besides, can't lose anything when I don't have anything to lose. san fransisco sightseeing cheap spanish holiday outdoor villa lighting wiley x
