Once a year about 15 million Mexican free-tailed bats (Tadarida brasiliensis) migrate up to 1,500 kilometers from wintering grounds, seamlessly flying over the Mexican border to enter the United States. Their destination is the Bracken Cave in southern Texas, which will be their summer home between the months of March through October. While residing there, these bats emerge every night at dusk from the narrow 100-foot-wide opening of this enormous cave and begin their nightly commute to foraging grounds located up to 50 kilometers away. Upon arrival, they will spend the night hunting for insects in mid-air while providing a valuable service to local farmers by keeping crop pests in check. Close to the break of dawn, as the night of hunting comes to an end, these bats will begin making their trip back to the roost.

Measures of spatial cognition and memory.
A weight-carrying structure for navigation of the air that is supported either by its own buoyancy or by the dynamic action of the air against its surfaces. (Webster, 1973)
A process through which individuals encode information about their environmental CUES to facilitate SPATIAL NAVIGATION.
Process by which organisms use various cues to develop a route to a destination and their ability to travel such a planned route.
Neurons in the ENTORHINAL CORTEX that project to the HIPPOCAMPUS. Grid cells and PLACE CELLS play a role in cognitive representation of spatial memory and navigation.
