The bird family Tytonidae, which includes the barn owls Tyto and the bay owls Phodilus, is one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the ...
The owl's remains date back to the Miocene-Pliocene boundary 5.5 to 5 million years ago. The fossil bones are about 60% as long again as a modern barn owl, [1] giving a total length of about 50–65 cm for T. robusta. This owl provides an interesting case study of evolution and insular gigantism.
Three species that are sometimes considered to be a single species known as barn owl or common barn owl: Western barn owl Tyto alba, from Europe, Africa, and the Middle East; American barn owl Tyto furcata, from the Americas; Eastern barn owl Tyto javanica, from southeast Asia and Australasia; Andaman masked owl Tyto deroepstorffi endemic to ...
The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. [3] However, the largest-bodied race of barn owl, T. f. furcata from Cuba and Jamaica, is also an island race, albeit being found on more sizeable islands with larger prey and few larger owls competing for dietary resources. [4]
The species was sympatric with the American barn owl (Tyto furcata), which was much more common on the Bahamas at the time than it is today, and also had a radically different diet than today, having shifted from a diet of primarily brown anoles (Anolis sagrei) to primarily rats and house mice today. The New Providence site contained only two ...
Noel's barn owl (Tyto noeli) found in Cuba; Rivero's barn owl (Tyto riveroi) found in Cuba; Cuban barn owl (Tyto sp.) found in Cuba; Hispaniolan barn owl (Tyto ostologa) found in Hispaniola; Bahaman barn owl (Tyto pollens) found in Little Exuma, New Providence, and maybe Andros Island, the Bahamas - may have survived into the 16th century
The population of the Australian masked owl on the mainland is declining and several states have placed this owl on the Species Conservation Status list. In Victoria (Australia) , the masked owl is a listed threatened bird, [ 10 ] and an Action Statement has been prepared under the Flora and Fauna Guarantee Act 1988 .
Barn owl on Lithuanian silver coin of 5 litas (2002) The Western Barn owl is relatively common throughout most of its range and is not considered globally threatened. However, locally severe declines from organochlorine (e.g., DDT) poisoning in the mid-20th century and rodenticides in the late 20th century have affected some populations.
