Top 9 Most Dangerous Birds

When you think about birds, you probably think of small, cute animals flying through the air, swooping down to reach their nest. Maybe you think of those “pretty” song birds in the morning. I, personally find them annoying. In any case, the image of a bird generally doesn’t produce anything terrifying. However, not all birds are cute, and not all of them are nice, so to speak. There are hundreds of birds that could attack a human, and do a lot of damage. Here is a list of nine most dangerous bird.

1. Cassowaries Cassowaries, an endangered species, are large, flightless birds that live in the rainforests, woodlands and swamps of Australia. Cassowaries are unpredictable, aggressive and are known to kick up their large, clawed feet. Their kicks are capable of breaking bones, and their claws have been likened to daggers.

2. Ostriches:  Ostriches are suspicious, skittish and can be dangerous. They're the largest living bird (they can reach over 9 feet tall and 350 pounds) and they can outrun you (a steady 30 miles an hour for 10 miles straight). Like the cassowary, they have strong legs (their kick can kill a hyena) and sharp claws.

3. Canada Geese: Canada geese are very aggressive and, particularly if you (purposely or inadvertently) come near their nests or young, they may chase you away and even bite you.

4. Seagulls: Seagulls are extremely aggressive and are known to attack and even peck at people's heads to protect their nests and young. In fact, in Britain people have been forced to carry umbrellas to avoid the attacks, at least one woman was taken to an emergency room with deep beak wounds to her head, and a pet dog was killed by the birds.

5. Owls: Owls are raptors, or birds of prey, and they use their talons and beaks to kill and eat their catch. In a closed space, or if the bird was scared or agitated, it could cause serious harm to you. 

Hawk And Falcon
6. Hawks and Falcons: Also birds of prey, the sharp talons and beaks that hawks and falcons use to hunt, along with their quick speed and agility, pose serious dangers to humans, even if the birds are just babies (falcons' beaks are also specially configured to cut through the spinal cords of their prey).

7. Eagles:  Eagles are strong (strong enough to carry away something that weighs four pounds), aggressive birds, and although they don't pose much of a danger to humans in the wild, in a closed space their beak and talons could easily harm a human. (FYI, they can eat about a pound of fish in just four minutes.)

8. Vultures:  If cornered, a vulture (many species of which are now endangered) may hiss or make a low grunting sound at you. They, of course, also have sharp, hooked beaks that can tear meat, along with excellent eyesight.

9. Rheas: The rhea, native to South America, is a large, flightless bird that can grow to be 60-80 pounds. Though smaller than ostriches and not as aggressive as cassowaries, rheas have heavily muscled legs, hard spurs on their feet and their kicks can bring a force of 800 pounds per square inch. Source: Article

Animals have personalities too…..

An individual's personality can have a big effect on their life. Some people are outgoing and gregarious while others find novel situations stressful which can be detrimental to their health and wellbeing. Increasingly, scientists are discovering that animals are no different. A new study led by Dr Kathryn Arnold, of the Environment Department at the University of York has added important experimental evidence showing that animal personalities are reflected in their oxidative stress profiles. The research is published in the Journal of Experimental Biology. Dr Arnold teamed up with graduate student Katherine Herborn, at the Institute of Biodiversity, Animal Health and Comparative Medicine at the University of Glasgow, to classify the personalities of 22 greenfinches. They tested each bird's reactions to a novel situation by adding a brightly coloured cookie-cutter to each greenfinch's food bowl, and timing how long it took for the birds to pluck up courage to approach the  food. The researchers found that the boldes birds took only a few seconds to overcome their fear while more timid birds took up to 30 minutes to approach their meal. Dr Arnold and Katherine Herborn also measured the greenfinches' motivation to explore by attaching an intriguing object to the birds' perches and timing how long it took them to land next to it. However, there was no correlation between the birds' courage and curiosity. The researchers then measured the birds' damaging reactive oxygen metabolite levels and their defences against them. Comparing the bird's blood oxidative profiles with their personalities, the team found that the most timid birds had the highest levels of damaging oxygen toxins and the weakest defences, so they suffered more oxidative stress than braver individuals. Also, the scientists found that the most curious birds (those that approached objects fastest) had better defences against oxidative damage than less curious greenfinches. Dr Arnold wants to extend the work to establish how personality traits affects birds in the wild. She says, ''Neophobic birds – those that are afraid of new things – may suffer high costs of oxidative stress and die early because they paid these physiological costs, but they might also be less likely to be eaten by a predator because they are more wary than bolder birds.'' The research also involved scientists at The Edward Grey Institute, Department of Zoology at Oxford and the WALTHAM Centre for Pet Nutrition at Melton Mowbray, Leicestershire. The research was part-funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Royal Society. Source: Article,
