There are some things we can do now to help bats.Some are as simple as putting up a bat house.
Bat Houses Buy a bat house or kit. Build it yourself. Find free plans online.
Bat Habitat Bats need more than a roost. They need a place to forage for insects or nectar. They also need fields, forests, marshes and chaparral.They need water. Permanent wet areas are critical for bats. You can find a local group working to save habitat in your area.
Adopt a bat Bat Conservation International has several programs to support bats. They sponsor conservation and save thousands of bats a year.
Don't trim your palm trees At least two species roost under dead palm fronds, the western yellow bat and the big brown bat. Cosmetic trimming is one of the biggest threats to the Western yellow bat. Not only does trimming eliminate potential roosting places, but if done during the months of May through September, it may actually injure the babies. Birds like the orioles also nest in palm fronds. You can put up a predator guard around the tree to protect the bat pups and bird chicks.
Keep cats indoors Domestic cats are not a natural predator in the Western Hemisphere but were brought over by settlers.There are an estimated 60 million cats kept as pets in the US. If each cat kills only one bird a year that would come to 60 million birds every year. That would account for more bird deaths than any oil spill. Scientific studies actually show that cats kill hundreds of millions of migratory songbirds and small mammals, including bats each year.
Prevent Drownings Bats must drink water. They can loose up to 30% of their body weight by evaporation in a night. Often, birds as well as bats, drown in pools and livestock tanks. They could survive if there was a way they could get out of the water. I've often floated a board in my animals' water tanks to keep small animals from drowning.
