The osprey or more specifically the western osprey (Pandion haliaetus) — also called sea hawk, river hawk, and fish hawk — is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts.
The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey’s diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, Pandion and family, Pandionidae. Three subspecies are usually recognized; one of the former subspecies, cristatus, has recently been given full species status and is referred to as the eastern osprey.

Birdwatching, or humane birding, is a form of wildlife observation in which the observation of birds is a recreational activity or citizen science. It can be done with the naked eye, through a visual enhancement device like binoculars and telescopes, by listening for bird sounds, or by watching public live bird cams. Birdwatching often involves a significant auditory component, as many bird species are more easily detected and identified by ear than by eye. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Humane Birding, birdwatching, and twitching? *Birder.* The acceptable term used to describe the person who seriously pursues the hobby of birding. May be professional or amateur. *Birding.* (Humane Birding) A hobby in which individuals enjoy the challenge of bird study, listing, or other general activities involving bird life. *Bird-watcher.* A rather ambiguous term used to describe the person who watches birds for any reason at all, and should not be used to refer to the serious birder. An ornithologist is someone who studies ornithology — the branch of science devoted to birds. Ornithologists study every aspect of birds, including bird songs, flight patterns, physical appearance, and migration patterns. Birds are genetically related to dinosaurs, which is something else an ornithologist might study. Birds are a group of warm-blooded vertebrates constituting the class Aves, characterized by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5 cm bee hummingbird to the 2.75 m ostrich. There are about ten thousand living species, more than half of which are passerine, or “perching” birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. As with the arrival of affordable digital cameras, the development of more compact and affordable digital video cameras has made them more attractive and accessible to the birding community. Cross-over, non-linear digital models now exist that take high quality stills at acceptable resolutions, as well as being able to record and play audio and video. The ability to easily capture and reproduce not only the visual characteristics of a bird, but also its patterns of movement and its sound, has wide applications for birders in the field.
