List of bats by population

This is a list of bat species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.

This list is not comprehensive, as not all bats have had their numbers quantified.

Common name Binomial name Population Status Trend Notes Image
Christmas Island Pipistrelle Pipistrellus murrayi 4[1] CR[1] Decrease[1] Common and widespread until the 1980s. Population here was recorded in January 2009. An immediate capturing project was requested to save the species, and efforts for approval included a personal meeting with then-Australian environment minister Peter Garrett. Due to a potential cost of a few hundred thousand dollars, the government decided against quick action and instead undertook a bureaucratic feasibility study. After its eventual assent in August 2009 a team of experts travelled to Christmas Island to capture the remaining individuals but only one was detected, which managed not to be caught. Its subsequent disappearance may be one of very few times extinction has been witnessed first-hand. Reasons for the bat's decline remain unknown.[1][2]
Cuban Greater Funnel-eared Bat Natalus primus 100[3] CR[3] Decrease[3] Maximum estimate. Only found in a single cave.[3]

Giant golden-crowned flying fox Acerodon jubatus 10 000[22] EN[22] Unknown[22] Rough estimate; probably no more than 20 000.[22]
Pemba Flying Fox Pteropus voeltzkowi 19 000[23] VU[23] Increase[23] Increase from a few hundred in the early 1990s.[23]
Mauritian flying fox Pteropus niger 25 000[9] EN[9] Decrease[9] Minimum estimate.[9]
New Zealand lesser short-tailed bat Mystacina tuberculata 30 000[24] VU[24] Decrease[24] Minimum estimate.[24]
Madagascan flying fox Pteropus rufus 300 000[25] VU[25] Decrease[25]
Grey-headed flying fox Pteropus poliocephalus 320 000 - 674 000[26] VU[27] Decrease [27] Estimates are based on incomplete knowledge of camp location and use.[26]
Indiana bat Myotis sodalis 387 300[28] EN[28] Decrease[28] Though numbers are large compared to other bats classified as endangered, this species is listed as such due to a >50% decline over the past decade.[28]

In an attempt to avert it I met Peter Garrett, then the environment minister, and warned him of the impending loss. I had brought offers of assistance and expertise from the Australian Mammal Society to his attention. The society was confident the species could be saved - at a cost of perhaps only a few hundred thousand dollars. But Garrett was convinced by the orthodoxy that ecosystems rather than species should be the focus of the national conservation effort, and I got the message that nothing would be done.
