Skim milk, yogurt, cheese, etc. are listed as sources of the most absorbable percentage of calcium (further down the page in the absorption table).
Mickey... certainly there is evidence on both sides of the subject.
The Dairy Council used to advertise that "Milk builds strong bones". They were sued in court to prove it, and with all the big-money research, they simply couldn't. So the courts ordered the slogan stopped, for false advertising.
Now they keep it vague: "Milk does a body good".
What good? The Dairy Council won't actually say.
After looking at 34 published studies in 16 countries, researchers at Yale University found that countries with the highest rates of osteoporosis “including the United States, Sweden, and Finland” are those in which people consume the most meat, milk, and other animal foods. This study also showed that African Americans, who consume, on average, more than 1,000 mg of calcium per day, are nine times more likely to experience hip fractures than are South African blacks, whose daily calcium intake is only 196 mg. Says McDougall, “[O]n a nation-by-nation basis, people who consume the most calcium have the weakest bones and the highest rates of osteoporosis. ... Only in those places where calcium and protein are eaten in relatively high quantities does a deficiency of bone calcium exist, due to an excess of animal protein.”

"It turns out that the relationship between the proteins in dairy products and the calcium in bones is a rocky one. First of all, calcium appears to be ultimately pulled from bones to escort digested animal protein from any source -- not just dairy products -- on its trek through the body. Since the average American's diet is protein-heavy to begin with, some experts say that eating lots of dairy foods may actually cause people to lose calcium. "When you eat a protein food, such as milk, you may be swallowing calcium, but you turn around and excrete calcium in your urine," says Donna Herlock, MD, spokeswoman for the Physicians Committee for Responsible Medicine, a nonprofit advocacy group opposed to milk consumption.
To buttress her point, Herlock points to a portion of the Harvard Nurses' Health study published in the June 1997 issue of the American Journal of Public Health. The study found that women who ate lots of dairy products had higher rates of bone fractures than women who rarely touched the stuff. It suggested that drinking more milk didn't provide any substantial protection against hip or forearm fractures in middle-aged and older women, writes Diane Feskanich, ScD, a professor at Harvard Medical School in Cambridge, Mass., and the study's lead author. "We considered the possibility that dairy protein was responsible for the increase in risk of hip fractures," she says."
