Bats

Unprecedented numbers of bats began dying at wind power facilities around the turn of the millennium. USGS scientists are working to uncover the  underlying reasons for bat susceptibility to wind turbines by closely studying the species most affected, and by studying their behavior near wind turbines. Insights from these studies serves as a foundation for developing and testing bat deterrent technologies and wind facility management practices to reduce bat mortality.

Statistical Tools for Wind and Solar Energy Development and Operations

Solar and wind power development is increasing exponentially in the United States. However, these energy sources may affect wildlife, either directly from collisions with the turbine blades or photovoltaic arrays or indirectly from loss of habitat and migration routes. An important component to understanding the effects of these renewable energy projects on wildlife is accurate and precise...

Bat Research in California

The primary goal of this bat research program is to develop projects that increase our understanding of basic ecology and natural history of western bat species, while simultaneously providing needed data to inform conservation measures and management decisions in the West. Dr. Brian Halstead, together with Gabriel Reyes, studies the habitat and resource selection, movement ecology, demography...

Ecology and Distribution of the Endangered Hawaiian Hoary Bat

The Hawaiian Hoary Bat (Lasiurus cinereus semotus) is the only extant land mammal native to the Hawaiian archipelago. It is listed as endangered due to apparent population declines, and a lack of knowledge concerning its distribution, abundance, and habitat needs. Agencies and landowners in Hawai‘i seek to assist in the creation of sustainable uses for managed lands while also protecting bat...

Monitoring and Researching Bat Activity at Wind Turbines with Videography

The rapid expansion of wind energy nationwide is an important step toward reducing dependence on non-renewable sources of power. However, the magnitude of the wildlife impacts at wind energy facilities is a newly recognized threat, and the cumulative long-term impacts to various bat species are of increasing concern. It is estimated that more than 450,000 bat fatalities now occur each year at wind...

Energy development and the airspace

Today, the alternative energy and telecommunications industries are developing the airspace much the way metropolitan growth and mechanized agriculture develop the landscape. NOROCK scientists and partners are using both historical and traditional technologies in new and innovative ways to observe wildlife behaviors in response to these changing habitats.

North American Bat Monitoring Program (NABat)

North American bats face unprecedented threats including habitat loss and fragmentation, white-nose syndrome, wind energy development, and climate change. However, it is difficult to evaluate the impacts of these threats due to a lack of basic information about the distribution and abundance of bats across the continent. Although bat monitoring has long been conducted in individual areas and for...

Ecology of Insect-eating Bats

Bats are the only flying mammals that are active mostly at night and occur on all continents except Antarctica. Bats are ecologically diverse, with a range of species that specialize in feeding on fruit, nectar, blood, fish, small mammals, and insects. However, of the more than 1,100 known species of bats on Earth, the majority specialize in feeding on insects. In the United States for example, of...

Bat Fatalities at Wind Turbines—Investigating the Causes and Consequences

Wind energy is one of the fastest-growing industries in the world and represents an important step toward reducing dependence on nonrenewable sources of power. However, widespread deployment of industrial wind turbines is having unprecedented adverse effects on certain species of bats that roost in trees and migrate. Bats are beneficial consumers of agricultural insect pests and migratory species...
