osprey with catch at Peel Harvey Estuary. The genus Pandion has several adaptations that suit its piscivorous lifestyle, these include reversible outer toes, sharp spicules on the underside of the toes, [24] closable nostrils to keep out water during dives, and backwards-facing scales on the talons which act as barbs to help hold its catch. The ...
The osprey and owls are the only raptors whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. This is particularly helpful when they grab slippery fish. [26] The osprey is 0.9–2.1 kg (2.0–4.6 lb) in weight and 50–66 cm (20–26 in) in length with a 127–180 cm (50–71 in) wingspan.
Another benefit is that this strategy helps ensure the ongoing processes of evolution and adaptation within their environments. As a last resort, ex situ conservation may be used on some or all of the population, when in situ conservation is too difficult, or impossible. The species gets adjusted to the natural disasters like drought, floods ...

Arts", at the time, referred to the practical application of an industrial, manufacturing, or scientific pursuit, rather than to its current meaning. Additionally, a variety of both agricultural and arts-related agencies were required to report to the commissioner, and to provide statistical information to the bureau.
Extent of adaptation is directly related to intensity of selection, genetic diversity, effective population size and number of generations in captivity. Characteristics selected for in captivity are overwhelmingly disadvantageous in the wild, so such adaptations can lead to reduced fitness following reintroduction.
Over 50 US service members have died in Osprey crashes since the program began
An Osprey crash in Australia that killed three Marines last August was caused by multiple pilot errors during a near mid-air collision, a military investigation has found. Two Marines were killed ...
