edge habitat an area in which habitats transition such as where a field transitions to a woodland. Many species of birds take advantage of edge habitats such as Gray Catbird, Eastern Kingbird and Eastern Towhee.

fish ladder a man-made series of pools at the side of a stream arranged like ascending steps, enabling migrating fish to swim upstream around a dam or other obstruction
fledglings young birds that have just left the nest, but are still not ready to go off completely on their own
flora and fauna the plants (flora) and animals (fauna) found in a specific area
flotsam and jetsam a general term used to describe anything that is floating in the water or possibly washed up on shore
food chain a community of organisms in which each member is eaten in turn by another member
fry recently hatched or juvenile fish
fungi a kingdom of plantlike organisms that grow without roots, stems, leaves and photosynthesis, such as mushrooms and lichen
glacial lake the result of melted ice from retreating glacier
gneiss igneous or sedimentary rocks that were subjected to metamorphic conditions such as high heat and pressure
gut a narrow passage or channel of water
hacking A process during which young raptors (often abandoned) are raised by human caretakers in a type of nest box, called a hack. Note: Raptors and other migratory birds are protected by law and this type of process can only be done by those who have the proper state and federal licenses.
herbaceous a green plant that is distinguished from woody plants by being leaflike in appearance and texture
hibernaculum zoologically refers to a shelter used by hibernating animals, botanically refers to a protective casing a plant uses to survive changing weather conditions during its dormant period.
host plants plants upon which butterflies lay their eggs and caterpillars feed
hummock a low mound or ridge of earth; a knoll
igneous rocks that are created when molten rock cools and solidifies
Important Bird Areas Sites that provide essential habitat for one or more species of birds and that make a significant contribution to the long-term viability of native avian populations. These may include sites for breeding, wintering, and/or migrating birds.
invasive a species that is non-native and due to rapid reproduction, strangling other species or changing the chemistry of the soil it becomes detrimental to the habitat in which it resides
irruption an unusually large influx of birds to an area; often associated with winter finches and usually caused by a shortage of food elsewhere
