Pallid bat with transmitter
A Pallid bat (Antrozous pallidus) is outfitted with a radio transmitter to help lead us to its roost. The transmitter is attached with a temporary adhesive that will wear off within around 2 weeks, about as long as the battery life of the transmitter lasts.

Adult Female Northern Harrier (Circus cyaneus)
An adult, female northern harrier (Circus cyaneus) flies overhead in Suisun Marsh, CA. Before habitat loss drove declines in the bird's populations, Suisun Marsh hosted the state's largest population of northern harriers.

Tree cores ready for dendrological analysis
These tree cores, taken from living trees with an increment borer, show the rings of the tree and allow scientists to learn about the tree's growth.

Scientist shows off a tree core fresh out of the tree
Scientists use a tool called an increment borer to remove cyllindrical tree cores from living trees. The cores show the tree's rings and help scientists learn about its growth.

ID Bands for Suisun Waterfowl
USGS scientists attach small metal bands, each with its own ID, to the ankles of adult waterfowl to identify where the animal was caught. When it is re-captured later in its migration, researchers can use that information to determine how far the animal traveled.
