Phenology which is derived from the Greek word phaino meaning to show or appear, is the study of periodic plant and animal life cycle events that are influenced by environmental changes, especially seasonal variations in temperature and precipitation driven by weather and climate. The USA National Phenology Network (USA-NPN) collects phenological data from across the United States. Also track the progress of The Ruby-throated Hummingbirds as they migrate north.
