The species is often rather less aggressive than some other owls, including related species like the spot-bellied eagle-, great horned and snowy owls, many of the northern Strix species and even some rather smaller owl species, which often fearlessly attack any person found to be nearing their nests. [101] Conversely to numerous threats and declines incurred by Eurasian eagle-owls, areas where human-dependent, non-native prey species such as brown rats (Rattus norvegicus) and rock pigeons (Columba livia) have flourished, have given the eagle-owls a primary food source and allowed them occupy regions where they were once marginalized or absent. The boreal and barn owls, to extend these examples, lack obvious visual cues such as white throat patches (puffed up in displaying eagle-owls), again indicative of primary activity being in darker periods. The iris is most often orange but is fairly variable. They hun different prey species, predominantly small mammals but also birds of varying sizes, reptiles, amphibians, fish, large insects, and other assorted invertebrates. Some, including the RSPB, have claimed that it had disappeared about 10,000–9,000 years ago, after the last ice age, but fossil remains found in Meare Lake Village indicate the eagle-owl occurring as recently as roughly 2,000 years ago in the fossil record. [124] Wind turbine collisions can also be a serious cause of mortality locally. The World Owl Trust stated that they believe some eagle-owls occurring in North England and Scotland are naturally occurring, making the flight of roughly 350 to 400 km (220 to 250 mi) from the west coast of Norway to Shetland and the east coast of Scotland, as well as possibly from the coasts of the Netherlands and Belgium to the south. [132] The largest reintroduction there occurred from the 1970s to the 1990s in the Eifel region, near the border with Belgium and Luxembourg. Similarly, Eurasian eagle-owls living in the Tibetan highlands and Himalayas may in some ancedotal cases vacate their normal territories when winter hits and move south. Barred owl. Mandarin duck. [9], In addition to being one of the largest living species of owl, the Eurasian eagle-owl is also one of the most widely distributed. [6][37] The great horned owls and Eurasian eagle-owls are barely distinct as species, with a similar level of divergence in their plumages as the Eurasian and North American representations of the great grey owl or the long-eared owl. [6][20] The average number of eggs laid varies with latitude in Europe. [6] More outward physical differences exist between the great horned owl and the Eurasian eagle-owl than in those two examples, including a great size difference favoring the Eurasian species, the great horned owl’s horizontal rather than vertical underside barring, yellow rather than orange eyes, and a much stronger black bracket to the facial disc, not to mention a number of differences in their reproductive behaviour and distinctive voices. [4][17] Another is possibly the spot-bellied eagle-owl (B. nipalensis), which is strikingly different looking, with stark brown plumage, rather than the warm hues typical of the Eurasian, bold spotting on a whitish background on the belly, and somewhat askew ear tufts that are bold white with light brown crossbars on the front. The wings and tail are barred. [95] Even those near the northern limits of their range, where winters are harsh and likely to bear little in food, the eagle-owl does not leave its native range. [112], The Eurasian eagle-owl has a very wide range across much of Europe and Asia, estimated to be about 32,000,000 km2 (12,000,000 sq mi). bengalensis). [8] The discrepancy of aggressiveness at the nest between the Eurasian eagle-owl and its Nearctic counterpart may be correlated to variation in the extent of nest predation that the species endured during the evolutionary process. [92] Nearly as important in territorial behaviour as vocalization is the white throat patch. Life Span. [136] From 1994 to 2007, 73 escaped eagle-owls were not registered as returned, while 50 escapees were recaptured. [6] Another offshoot of the northern Bubo group is the snowy owl. There, very few areas are not heavily modified by human civilisation, thus exposing the birds to the risk of collisions with deadly man-made objects (e.g. Bubo group is the largest one in the species in this part of Germany into established.
