Screech owls are typical owls (Strigidae) belonging to the genus Megascops with 23 living species. For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data.

Screech owls are restricted to the Americas. Some species formerly placed with them are nowadays considered more distinct (see below for details).

Description

Similar to other owls, the screech owl females are larger than the males of their species. They have a compact size and shape. They are small and agile, and about 7 to 10 inches tall and have a wingspan around 18 to 24 inches. They have prominent, wide-set feather tufts with bright yellow/green eyes. They have different brownish hues with whitish, patterned underside. This coloration helps them get camouflage against the tree bark.

Ecology and behavior

Screech owls hunt from perches in semiopen landscapes. They prefer areas that contain old trees with hollows; these are home to their prey, which includes insects, reptiles, small mammals such as bats and mice, and small birds. Screech owls have a good sense of hearing, which helps them locate their prey in any habitat. They also possess well-developed raptorial claws and a curved bill, both of which are used for tearing their prey into pieces small enough to swallow easily. They usually carry their prey back to their nests, presumably to guard against the chance of losing their meal to a larger raptor.

Screech owls are primarily solitary. During the late winter breeding season, however, males make nests in cavities, sometimes reusing abandoned nests of other animals, to try to attract females. The females select their mate based on the quality of the cavity and the food located inside. During the incubation period, the male feeds the female. These birds are monogamous, with biparental care. The young of most screech owls are altricial to semialtricial.^[1]

Northern screech owls are found in eastern states, such as New Jersey and New York. The screech owls are named for their piercing calls. Their normal territorial call is not a hoot as with some owls, but a trill consisting of more than four individual calls per second given in rapid succession (although the sound does not resemble screeching or screaming). They also have a kind of "song" used in courtship, and as a duet, between members of a pair. Calls differ widely between species in type and pitch, and in the field are often the first indication of these birds' presence, as well as the most reliable means to distinguish between species. The distinctness of many species of screech owls was first realized when vastly differing calls of externally similar birds from adjacent regions were noted.

Evolution, taxonomy, and systematics

The genus Megascops was introduced by German naturalist Johann Jakob Kaup in 1848.^[2] The type species is the eastern screech owl (Megascops asio).^[3] The evolutionary relationships of the scops and screech owls are not entirely clear. What is certain is that they are very closely related; they may be considered sister lineages which fill essentially the same ecological niche in their allopatric ranges. A screech owl fossil from the Late Pliocene of Kansas^[4] (which is almost identical to eastern and western screech owls) indicates a longstanding presence of these birds in the Americas, while coeval scops owl fossils very similar to the Eurasian scops owl have been found at S'Onix on Majorca.^[5] The scops and screech owl lineage probably evolved at some time during the Miocene (like most other genera of typical owls), and the three (see below) modern lineages separated perhaps roughly 5 million years ago. Note, no reliable estimate of divergence time is known, as Otus and Megascops are osteologically very similar, as is to be expected from a group that has apparently conserved its ecomorphology since before its evolutionary radiation. Like almost all scops and screech owls today, their common ancestor was in all probability already a small owl, with ear tufts and at least the upper tarsus ("leg") feathered.

However that may be, the hypothesis that the group evolved from Old World stock^[6] is tentatively supported by cytochrome b sequence data.^[7][8] The screech owls also have a different placement of the procoracoid (less of an anterior incline) and coracoid bones compared to other New World owls.^[9]

The splitting of Otus sensu lato

While late-19th-century ornithologists knew little of the variation of these birds, which often live in far-off places, with every new taxon described a few differences between the Old and New World "scops" owls became more and more prominent. Namely, the scops owls give a whistling call or a row of high-pitched hoots with fewer than four individual hoots per second. This call is given in social interaction or when the owl tries to scare away other animals. The screech owls, though, are named for their piercing trills of more than four individual notes per second, and as noted above, they also have a kind of song, which is absent in the scops owls. A few other differences are seen, such as brown coloration below being common in scops owls and almost never seen in screech owls, but the difference in vocalizations is most striking.

By the mid-19th century, Otus was becoming identified as encompassing more than one genus. First, in 1848, the screech owls were split off as Megascops. Subsequently, the highly apomorphic white-throated screech owl of the Andes was placed in the monotypic genus Macabra in 1854. Gymnasio was established in the same year for the Puerto Rican owl, and the bare-legged owl (or "Cuban screech owl") was separated in Gymnoglaux the following year; the latter genus was sometimes merged with Gymnasio by later authors.

By the early 20th century, the lumping together of taxa had come to be preferred. The third edition of the American Ornithologists' Union (AOU) checklist in 1910, placed the screech owls back in Otus. Although this move was never unequivocally accepted, it was the dominant throughout most of the 20th century. In 1988, attempts to resolve this were made by re-establishing all those genera split some 140 years earlier at subgenus rank inside Otus.^[10] Still, the diversity and distinctness of the group failed to come together in a good evolutionary and phylogenetic picture, and until the availability of DNA sequence data,t this could not be resolved. In the mid- to late 1990s, preliminary studies of mtDNA cytochrome b across a wide range of owls found that even the treatment as subgenera was probably unsustainable and suggested that most of the genera proposed around 1850 should be accepted.^[7][8] Though some debate arose about the reliability of these findings at first,^[11] they have been confirmed by subsequent studies. In 2003, the AOU formally accepted the genus Megascops again.^[12]

The bare-legged owl was also confirmed as distinct enough to warrant separation in its own genus. Furthermore, the white-throated screech owl was recognized as part of an ancient lineage of Megascops – including also the whiskered screech owl and the tropical screech owl, which previously were considered to be of unclear relationships – and indeed its call structure is not too dissimilar from the latter. Its distinct coloration, approximated in the southern whiskered screech owl (Megascops trichopsis mesamericanus), is thus likely the result of strong genetic drift.

Additionally, a population of the tropical screech owl from northern Colombia has recently been proposed as the Santa Marta screech owl (Megascops gilesi) to the IOC.^[13][14]

Systematikk Rike: Animalia Rekkje: Chordata Klasse: Aves Orden: Strigiformes Familie: Strigidae Slekt: Megascops Vitskapleg namn Megascops

Megascops er ei biologisk slekt av små ugler som samlar 21 nolevande kjente artar. Dei er farga i ulike brunaktige fargetonar. Nokre er polymorfe, og finst i ein grå og ein raudbrun morf.

Slekta har utbreiing avgrensa til Amerika og desse uglene er nærskylde Otus-uglene i «den gamle verda». Megascops blei skilt ut frå Otus siste gongen etter år 2000. Ulikskapen i lætet er ein påfallande skilnad mellom Megascops og Otus.

Nemninga på engelsk for Megascops-ugler er 'Screech owls'.

Skilding

Megascops-uglene er 16-25 centimeter i høgd, 45-61 cm i vengespenn og mange har godt synlege fjørtoppar som gjev øyrelignande utsjånad. Dei er farga i ulike brunaktige fargetonar, nokre gonger med ei lysare undersida og eller andlet, noko som bidreg til å kamuflere dei mot borken av tre. Nokre er polymorfe, og finst i ein grå og ein raudbrun morf. Megascops-uglene jaktar frå utkikkspostar i halvopne landskap. Dei føretrekker område som inneheld gamle hòle tre, der dei kan finne bytte som inkluderer insekt, reptil, små pattedyr som flaggermus og mus og andre småfuglar.

Megascops-uglene lever primært som einslege fuglar. Hannfuglen byggjer reiret i eit holrom, nokre gonger opphavleg laga av eit anna dyr. Under rugetida vil hannen mate hoa som rugar. Desse fuglane er monogame, begge foreldra tar omsut for avkommet.^{[treng kjelde]}

Dei normale territoriale ropa er ikkje er typiske uglelæte, men ei trille som består av meir enn 4 raske, individuelle tonar per sekund. I tillegg til dette har dei ein slags song som brukast under kurtise, og i duett mellom medlemmer av eit par.^{[treng kjelde]}

Skrikuvar (Megascops) är ett stort släkte i familjen ugglor som enbart förekommer i Nord- och Sydamerika.^[1] Tidigare placerades de i samma släkte som dvärguvar i Otus, men genetiska studier visar att de inte är närbesläktade. Ponderosaugglan (Psiloscops flammeolus) står nära skrikuvarna men urskiljs numera oftast i ett eget monotypiskt släkte.

Släktet skrikuvar består av 22-26 arter:

• Västlig skrikuv (M. kennicottii)
• Östlig skrikuv (M. asio)
• Balsasskrikuv (M. seductus)
• Kustskrikuv (M. cooperi)
• Mexikansk skrikuv (M. trichopsis)
• Chólibaskrikuv (M. choliba)
• Västperuansk skrikuv (M. roboratus)
• Köpckeskrikuv (M. koepckeae)
• Chiapasskrikuv (M. barbarus)
• Colombiaskrikuv (M. colombianus)
• Rostskrikuv (M. ingens)
• Kastanjeskrikuv (M. petersoni)
• Molnskogsskrikuv (M. marshalli)
• Gulbröstad skrikuv (M. watsonii)
• Svartkronad skrikuv (M. atricapilla)
• Höyskrikuv (M. hoyi)
• Långtofsad skrikuv (M. sanctaecatarinae)
• Guatemalaskrikuv (M. guatemalae)
  • Vattrad skrikuv (M. [g.] vermiculatus) – urskiljs som egen art av IOC och Birdlife
  • Roraimaskrikuv (M. [g.] roraimae) – urskiljs som egen art av IOC
  • Chocóskrikuv (M. [g.] centralis) – urskiljs som egen art av IOC
  • Naposkrikuv (M. [g.] napensis) – urskiljs som egen art av IOC
• Barbent skrikuv (M. clarkii)
• Puertoricoskrikuv (M. nudipes) – är möjligen mer avlägstet släkt med övriga, närmare ponderosauggla
• Vitstrupig skrikuv (M. albogularis)
