How much does a Mexican free-tailed bat weight?

It is hard to guess what a Mexican free-tailed bat weights. But we have the answer:

An adult Mexican free-tailed bat (Tadarida brasiliensis) on average weights 12 grams (0.03 lbs).

The Mexican free-tailed bat is from the family Molossidae (genus: Tadarida). It is usually born with about 3 grams (0.01 lbs). They can live for up to 15 years. When reaching adult age, they grow up to 4.1 cm (0′ 2″). On average, Mexican free-tailed bats can have babies 1 times per year with a litter size of 1.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The Mexican free-tailed bat or Brazilian free-tailed bat (Tadarida brasiliensis) is a medium-sized bat native to the Americas, regarded as one of the most abundant mammals in North America. Its proclivity towards roosting in huge numbers at relatively few locations makes it vulnerable to habitat destruction in spite of its abundance. The bat is considered a species of special concern in California as a result of declining populations. It has been claimed to have the fastest horizontal speed (as opposed to stoop diving speed) of any animal, reaching top ground speeds over 100 mph (161 km/h); its actual air speed has not been measured. The Texas Legislature designated the Mexican free-tailed bat the state mammal (flying) in 1995.
