  2. Tytonidae - Wikipedia

    en.wikipedia.org/wiki/Tytonidae

    The barn owl is relatively common throughout most of its range and not considered globally threatened. If considered as a single global species, the barn owl is the second most widely distributed of all raptors, after only the peregrine falcon. It is wider-ranging than the also somewhat cosmopolitan osprey.

  3. American barn owl - Wikipedia

    en.wikipedia.org/wiki/American_barn_owl

    The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. 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.

    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 ...

  5. List of mammalian gestation durations - Wikipedia

    The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental. For more information on how these estimates were ascertained, see Wikipedia's articles on gestational age.

  6. Tyto robusta - Wikipedia

    en.wikipedia.org/wiki/Tyto_robusta

    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.

    In the latter, the eggs develop in utero for about 28 days, with only about 10 days of external incubation (in contrast to a chicken egg, which spends about one day in tract and 21 days externally). [11] After laying her eggs, the female curls around them. The incubation period is divided into three phases.
