TUCSON, AZ (Tucson News Now) - Twenty thousand Mexicanfree-tailed bats filled the sky over the Rillito River Thursday night justafter sunset. The bats, mostly female, will be in Tucson through Augustand perhaps into September. Each will have one or two young. Rightnow, the young will stay under the Campbell Avenue bridge as the mothers go andsearch for insects for food throughout the night.
"They go to theagricultural fields and feed on huge numbers of insects. So, this is whythey're very important here because they are bug-eating machines," saidCarole DeAngeli, a docent with the Arizona-Sonora Desert Museum.
"I've never seenthem before, so, just to come down here and see that we live so close tosomething that's really cool, it's pretty fun to see something that unique inTucson," said Andrea Cambron, who was watching the bats at the CampbellAvenue bridge over the Rillito.
The bats can also beseen taking to the skies from the Pantano River Park at Pantano and 22ndStreet.
