Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Breed bats in captivity Eight studies evaluated the effects of breeding bats in captivity on bat populations. Three studies were in the USA, two in the UK, and one in each of Italy, Brazil and New Zealand. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (8 STUDIES) Reproductive success (6 studies): Six studies in the USA, UK, Italy and Brazil found that 6–100% of female bats captured in the wild successfully conceived, gave birth and reared young in captivity. Two studies in the UK and Brazil found that two of five and two of three bats born in captivity successfully gave birth to live young. Survival (8 studies): Seven studies in the USA, UK, Italy and Brazil found that 20–100% of bat pups born in captivity survived from between 10 days to adulthood. One study in New Zealand found that two of five New Zealand lesser short-tailed bat pups born in captivity survived, both of which were hand-reared.

Two studies were in the UK, one was in Italy and one in Brazil. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (4 STUDIES) Survival (4 studies): One study in Brazil found that two hand-reared orphaned greater spear-nosed bats survived for over three months in captivity. Two studies in the UK and Italy found that 70–90% of hand-reared pipistrelle bats survived for at least 4–14 days after release into the wild, and six of 21 bats joined wild bat colonies. One study in the UK found that pipistrelle bats that flew in a large flight cage for long periods before release survived for longer and were more active than bats that flew for short periods or in a small enclosure. One study in the UK found that 13% of ringed hand-reared pipstrelle bats were found alive in bat boxes 38 days to almost four years after release into the wild. Condition (1 study): One study in Brazil found that two orphaned greater spear-nosed bats increased in body weight and size after being hand-reared, and reached a normal size for the species after 60 days.
