FAQs

Does banding hurt birds?

No, banding does not hurt birds. When proper techniques and equipment are carefully employed, it’s a safe procedure for birds. Trained banders, who apply their expertise and thoughtfulness towards the health and well-being of the birds, follow strict procedures based on the Bander’s ethic code.

Are there invasive reptiles other than Burmese pythons in the United States that people should be concerned about?

Free-ranging reptiles representing dozens of species from around the world are detected in the United States in any given year, usually as a result of escape or illegal release. Fortunately, many of these individuals fail to establish reproductive populations, but all non-native species can potentially pose risks when introduced. Florida is a major transportation hub and has a climate that’s...

Principal Aquifers

An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to wells and springs. This site explains the geology of aquifers and provides a general overview and maps of the principal aquifers of the United states.
