Do great horned owls really have horns?

About Great Horned Owl Feathers
Great Horned Owl feathers are entirely too soft to offer any type of air resistance at all. They serve two primary purposes: one is definitely to protect the bird from cold, and the other is to give it a soft but soundless flight.
Importance of Their Feathers in Flight
Unlike Falcon feathers, Great Horned Owl feathers are not aerodynamic, but they are nonetheless accommodated for soundless flight. That’s right. Their feathers are so created that they do not make any sound even if it gets near their prey.
Molting
Like other species, Great Horned Owls regularly replace their feathers in a process called molting. It generally takes place once a year, beginning after their young have fledged and the need for their resources are lower.
Ear-tufts
Their ear-tufts, also known as plumicorns or feather tufts, are showcase feathers and have nothing to do with hearing. It is used to display the state of mind, such as happiness, anger, and fear. They also support them to protect them from predators.

What is the color of a great horned owl's throat?
A variable-sized white patch is seen on the throat. The white throat may continue as a streak running down the middle of the breast even when the birds are not displaying, which in particularly pale individuals can widen at the belly into a large white area. South American great horned owls typically have a smaller white throat patch, often unseen unless actively displaying, and rarely display the white area on the chest. Individual and regional variations in overall color occur, with birds from the subarctic showing a washed-out, light-buff color, while those from the Pacific Coast of North America, Central America, and much of South America can be a dark brownish color overlaid with blackish blotching. The skin of the feet and legs, though almost entirely obscured by feathers, is black. Even tropical great horned owls have feathered legs and feet. The feathers on the feet of the great horned owl are the second-longest known in any owl (after the snowy owl ). The bill is dark gunmetal-gray, as are the talons.
How long are owl wings?
The wing chord length is 297–400 mm (11.7–15.7 in). The wing loading, the measured wing area compared to weight, is high, meaning the wings are relatively small in surface area for the bird's weight; the species' wing loading has been described as proportionately the highest among raptors. The tail, being relatively short as is typical of most owls, is 175 to 252 mm (6.9 to 9.9 in) long. Like other owl species, the great horned owl is capable of “silent flight”, which is the way owls fly while making almost no discernable noise, despite their large size. This is made possible thanks to three main components of the owl's wing structure. The leading edge of their feathers have serrations that help to disrupt the turbulence generated by wing flapping, then the softer feathers help deaden the sound, and finally the trailing fringe of the feathers that works to finish cutting the sounds made by flight. The structure of the great horned owl wing also allows it to fly at a very low speeds for the size of the species, as slow as 2 miles per hour when they are gliding on breezes.
Why do great horned owls lay eggs early?
In Wisconsin, eggs in rural nests hatched a month earlier (January rather than February) than their counterparts in rural areas, probably due to increased protection from wind and cold. Nesting owls at sites in Winnipeg, Manitoba began nesting five to six weeks earlier than those in rural parts of Manitoba, presumably due to experiencing an extremely warm winter by Winnipeg’s standards, as well as benefitting from the local urban heat island.
How big are owls?
The great horned owl is the heaviest extant owl in Central and South America and is the second-heaviest owl in North America, after the closely related, but very different-looking snowy owl. It is heavily built, with a barrel-shaped body, a large head, and broad wings. Its size can vary considerably across its range, with populations in interior Alaska and Ontario being largest and populations in California and Texas being smallest, though those from the Yucatán Peninsula and Baja California appear to be even smaller. Adult great horned owls range in length from 43 to 64 cm (17 to 25 in), with an average of 55 cm (22 in), and possess a wingspan of 91 to 153 cm (3 ft 0 in to 5 ft 0 in), with an average of 122 cm (48 in). Females are somewhat larger than males. Mean body weight is 1,608 g (3.545 lb) for females and 1,224 g (2.698 lb) for males. Depending on subspecies, maximum weight can reach 2,503 g (5.518 lb).

Why are owls taller in trees?
Additionally, urban nesting individuals utilize trees that are taller/wider in diameter and nest much higher compared to rural nesting Great Horned Owls. The reason behind this increased tree height is due to the fact that urban areas have large trees used for ornamentation, shade and shelter. The higher nesting within the taller trees was attributed to human avoidance. Both rural and urban nesting sites were often within range of paved roads, likely a result of the great horned owl’s tendency to hunt along roadways
How much force does a Great Horned Owl need to open its talons?
When clenched, a Great Horned Owl’s strong talons require a force of 28 pounds to open. The owls use this deadly grip to sever the spine of large prey.

Overview
Description
The great horned owl is generally colored for camouflage.

All subspecies are darkly barred to some extent along the sides, as well.
Taxonomy
The great horned owl is part of the genus Bubo, which may include as many as 25 other extant taxa, predominantly distributed throughout Africa. The great horned owl represents one of the one or two radiations of this genus across the Bering land bridge to the Americas. Whereas the Magellanic horned owl clearly divided once the owl had spread through the Americas, the consensus seems …
Distribution and habitat
The breeding habitat of the great horned owl extends high into the subarctic of North America, where they are found up to the northwestern and southern Mackenzie Mountains, Keewatin, Ontario, northern Manitoba, Fort Chimo in Ungava, Okak, Newfoundland and Labrador, Anticosti Island and Prince Edward Island. They are distributed throughout most of North and very spottily in Cent…
Behavior
In most aspects of their behavior, great horned owls are typical of owls and most birds of prey. From experimentally raising young owls in captivity, Paul L. Errington felt that they were a bird of "essentially low intelligence" who could only hunt when partially wild and instinctually driven by hunger to hunt whatever they first encounter. He showed captive birds that were provided strips of meat fro…
Prey and trophic ecology
Prey can vary greatly based on opportunity. According to one author, "Almost any living creature that walks, crawls, flies, or swims, except the large mammals, is the great horned owl's legitimate prey". In fact, the great horned owl has the most diverse prey profile of any raptor in the Americas. Over 500 species have been identified as great horned owl prey, with dozens more identified only to genus or general type (especially numerous invertebrates) and presumably several more unkn…
Reproduction
Great horned owls are some of the earliest-breeding birds in North America, seemingly in part because of the lengthy nightfall at this time of year and additionally the competitive advantage it gives the owl over other raptors. In most of North America, courtship is from October to December and mates are chosen by December to January. This species was once thought to be strictly …
Mortality and longevity
Great horned owls seem to be the most long-living owl in North America. Among all owls, they may outrank even the larger Eurasian eagle owl in known longevity records from the wild, with almost 29 years being the highest age for an owl recorded in North America. In captivity, the record for the longest lived great horned owl was 50 years. A more typical top lifespan of a great horned owl is approximately 13 years. In general, great horned owls are most vulnerable in the e…
