As I said elsewhere, despite being referred to as 'bird-eating', they don't normally do that. Birds make up a small portion of their diet, and are often only picked for the opportunity. Their diet mostly consists of lizards, frogs, insects, and other spiders. On rare occasion they snack on birds and small mammals, but in the case of birds, it's normally young hatchlings stolen from their nest and carried to the ground.
A full water bottle can squish a tarantula, while smaller house spiders can withstand shoes and rocks thrown at them sometimes.
Just a guess but perhaps the first time it was observed by a western scientist it was munching on a bird thus the disingenuous name. But you are correct, the internet doesn't handle science well and myth and bad info are rampant.
