While the average height of a human is between 5.5 to 5.9 feet. However, when we compare the two species, we see that humans are much larger than these tiny birds.įor instance, osprey birds have an average overall length of 52 to 60 cm, while with their wings wide open the wingspan ranges between 127–180 cm (4.1-5.9 ft). Ospreys are extremely tolerant of humans, often nesting right next to busy highways and in densely populated cities. However, we can look at their overall lengths. We cannot really comment on the wingspan of humans, for obvious reasons that we don’t really have wings. Ospreys often come into conflict with humans, and so it raises a question in my mind who would win between the two? Ospreys live in close proximity to humans, so these two species have regular interactions. On average juvenile Osprey has a wingspan of about 120-160cm (47-62 in). Juvenile ospreys have a shorter wingspan than adult ospreys. However, if you are identifying or comparing on the basis of their wings, then you can easily tell apart the two by the length of their wings, that is their wingspan. Adults have yellow eyes, whereas juveniles have darker orange eyes. The first thing you would notice while identifying is its overall appearance, so to help you, the Juvenile ospreys have distinct white spots on the back of their body and also have a buffy shading on their breast.Īnother way to tell if it is an adult osprey or a juvenile is to look at their eyes. It’s not that complicated, as the young ones of birds look quite different in both appearance and size than the adult ones. Have you ever wondered that even if you do identify an Osprey, how would you tell if it is an adult osprey or a juvenile just by looking at its wings? They frequently hover briefly before diving feet first to catch a fish. These birds hunt for fish by circling high in the sky over relatively shallow water with steady wingbeats and bowed wings. Additionally, the female ospreys are much larger than the male ospreys, with a size difference of about 20%. On average Osprey has a wingspan of 152 – 167 cm (60 – 66 inches) or 5 – 5.9 feet. The Osprey is one of North America’s largest birds of prey, with a wingspan of more than 5 feet. Ospreys fly with shallow wing flapping and soar with their wings fully extended. Ospreys have arched wings and drooping ‘hands’ in flight, giving them a gull-like appearance. Ospreys are unique among hawks as they have a reversible outer toe, allowing them to grasp with two toes in front and two behind them. Ospreys are large, distinct-looking hawks. On the head, the facial skin is mostly grey.Ospreys can be found on all continents except Antarctica, though they are only seen as a non-breeding migrant in South America. The underparts appear pale, mainly white, with conspicuous spots, streaks and bars. Flight and tail feathers are dark brown, the latter with broad, paler grey-brown bars. Back and wings are “scaled” due to the white feather tips. The juvenile is brown above with spotted head and neck. The adult female is slightly larger than male and has less (or no) black spots on wing-coverts. Long, thin, bare legs and small feet are yellow. The bare, yellow facial skin becomes pink and red as the breeding season is in progress. Head, chin, throat and upper breast are grey. On the underparts, lower breast and underwing coverts are white and finely barred black, narrower than P. The long tail is black with broad white bar at mid-length and narrow white tip. The flight feathers are black with narrow white tips. We can see some black spots on scapulars and greater wing-coverts. typus, and with brown wash on the upperparts. The Madagascar Harrier-Hawk adult has grey plumage overall but paler than P. Related article: Harrier-hawks - Harriers - Crane Hawk Raptors of the World Par James Ferguson-Lees,David A.
