Species Highlight: Ural Owl – 10,000 Birds


In Germany, the final wild residing Ural Owl was shot in 1926, although there was a reintroduction program in Bavaria that began within the 2000s. The choice is to see a Ural Owl on the Leipzig Zoo – however I normally discover seeing owls in zoos reasonably miserable.

As an alternative of zoos, Ural Owls desire to dwell in areas with mature however not too dense main forests, usually near a gap (supply). That’s reasonably useful to find them when driving by means of the Northern components of Internal Mongolia – within the forests there, the highway might be typically the one opening. As a consequence, I noticed a Ural Owl nearly each day there, typically even two or three on the identical day.

Usually, Ural Owls are likely to happen in distant areas removed from human habitations (supply) – these areas should not arduous to search out in Internal Mongolia.

Partly as a consequence, the Ural Owl is categorized as Least Concern, with a inhabitants estimated between 640,000 and 1,052,000 adults throughout big areas. Many of those areas are comparatively distant and undeveloped, lowering the chance of owls dying from human exercise.

Based on one supply, Ural Owls should not too shy and could also be approached fairly intently, however I discovered this to not be true – there’s excessive variation between people. Some have been very shy certainly, and on common, I might rank this species as shier than each the Nice Gray Owl and the Northern Hawk Owl, each of which have been additionally encountered on this journey in related circumstances.

Thankfully, some Ural Owls are certainly comparatively relaxed when watched from far, as could be seen in this video.

Ural Owls are monogamous, residential, and extremely territorial, sustaining territories for a number of years. Particularly, they aggressively defend their nests.

This safety might even not directly cowl different chicken species – in an experiment, ground-nesting birds have been discovered to be most secure from predators similar to weasels and Corvids when nesting near the nest of the owl.

As regular for owls, the feminine is on common heavier (870 g) than the male (720 g). The common prey measurement – small mammals, primarily rodents – is about 44 g, about 5% of their physique weight.

Feminine owls appear to have the ability to time their egg-laying relying on prey availability –  in one research in Finland, solely 24% of the females laid eggs throughout years with low vole numbers, whereas 76% laid in peak years. 

The breeding success in Finland was additionally pushed by the age of the feminine Ural Owl. 3-5-year-old females have been discovered to be much less productive than these 6 to 9 years previous, and unusually, females greater than 10 years previous tended to put bigger and extra rounded eggs (supply).

For an owl, the Ural Owl has comparatively small eyes, a touch that the owl will not be completely nocturnal but in addition hunts within the daytime (supply).

And whereas owls are typically not thought-about to be very vivid, experiments confirmed that they realized from expertise when selecting their looking grounds.

One curious analysis outcome comes from analyzing the load and intercourse of voles in Finland – evaluating these caught by Ural Owls and people caught by the analysis biologists. Apparently, the Ural Owls caught bigger and reproductively lively voles than the researchers, indicating lively number of the mature voles as prey.

Lastly, a chunk of recommendation for individuals who run web sites on animals symbolizing this or that: Get your species proper!

For instance, spiritandsymbolism.com talks in regards to the Ural Owl African Symbolism, stating that the owl “holds vital symbolism in African tradition”. Unusual to be an emblem on a continent the place there are not any Ural Owls.

Or take tukanmedia.pl, which begins with the wonderful assertion “Ural Owl – Additionally known as tawny owls”. In the event you can’t even get the species proper, why ought to I belief your evaluation that previously, the Ural Owl “was thought-about an emblem of misfortune, an embodiment of the satan, and even a harbinger of dying”?

Then once more, different symbolic meanings of Ural Owls are simple, straightforward to grasp, and really seemingly confirmed by meticulous analysis: “The Ural Owl speaks of imbalances within the urinary facet but in addition steadiness” (supply).
