Owl release a pueo is a hawaiian owl
The pueo (Asio flammeus sandwichensis) is a subspecies of the short-eared owl that is endemic to Hawaii. The pueo is one of more famous of the various physical forms assumed by ʻaumākua (ancestor spirits) in Hawaiian culture.

Pueo inhabit forests and grasslands throughout the islands of Hawaiʻi, although their numbers seem to be declining, particularly in the last two decades, and especially on the island of Oʻahu, upon which they were at one time numerous. Pueo is listed by the state of Hawaiʻi as an endangered species on the island of Oʻahu.

Taxonomy
This taxon was first named by Andrew Bloxam (as the species Strix sandwichensis). He saw it, although did not collect a specimen, while in the Hawaiian Islands in 1825 as the naturalist on board HMS Blonde. It is now considered to be a subspecies of the short-eared owl, Asio flammeus, although Storrs Olson does not consider it to be distinct from Asio flammeus flammeus.
Threats to survival
Pueo nest on the ground, which makes their eggs and young susceptible to predation by the introduced small Asian mongoose and other predators, as well as by bulldozers.
Pueo are strongly affected by light pollution. They are often killed in vehicular accidents in which they dive toward the headlights of cars, possibly in an attempt to hunt. Many such collisions have been reported on Interstate H-3 and other newly built roadways in areas which once held high populations of pueo.
Pueo appear to be somewhat resistant to the avian malaria that has devastated many other endemic bird populations in Hawaii; however, they have recently become victim to a mysterious "sick owl syndrome", or SOS, in which large numbers of pueo have been found walking dazedly on roads, leading to death by collision. The cause of sick owl syndrome is unknown; it is suspected that pesticide toxicity may be responsible, particularly through secondary rodenticide poisoning. However, it has also been hypothesized that the cause may be an infectious agent, seizure-like confusion due to light pollution, or a variety of other causes.
