We associate birds with something calm and beautiful: light, independent of the perturbations of earthly life, they have always caused a kind of slight envy in humans. However, do not rush to relax - Mother Nature still has something to surprise us with. Among the huge variety of bird species, there are some that we do not advise anyone to meet.
Goshawk
The goshawk is a very beautiful bird and, like all the other members of the family, selfless. You shouldn't even think about getting close to the nest of this proud man: the hawk will fearlessly rush to attack the "guest", regardless of its size.
Ostrich
Making an ostrich angry is not the smartest decision. These birds zealously guard their territory and rush at every intruder. The speed of an ostrich can reach eighty kilometers per hour, so it will not be possible to escape. To top it all off, the ostrich has sharp claws on its paws, with one blow of which it can tear through the stomach of anyone.

Bicolor pitohuis
These strange little birds live in the forests of New Guinea. It is deadly to hunt them: the skin, feathers and internal organs of Pitohui dichrous contain a huge amount of batrachotoxin - a poison that is one hundred times stronger than strychnine. Scientists still cannot understand the reasons for such a trick of nature, because this bird is far from a hunter.
Griffon vulture
The common diet of vultures is carrion, and this is common knowledge. However, a study published in 2011 in the journal Nature showed that there may be exceptions to the rule. Griffon vultures, living in northern Spain, began to hunt livestock, moving from the category of scavengers to predators. A wounded person may well be the victim of such a bird: last year a young woman fell off a cliff and broke her leg - and the vultures managed to reach her before the rescuers.
Blue jay
Blue jays seem to be quite harmless creatures. They feed on insects and nuts - but do not mind stealing eggs from other birds. Approaching a blue jay's nest means deliberately risking your eyes. This small bird defends territory with the courage of an African lion: bird watchers have known cases of jays attacking hawks, raccoons, cats, squirrels and snakes.
Cassowary
Apart from the ostrich, the cassowary remains the only bird that has killed humans. The middle finger of the cassowary is equipped with a long, sharp claw that can easily release the guts of the victim. Of course, you must be very unlucky to meet a cassowary in its habitat - however, in theory it is quite possible.
Red cardinal
And one more little bird that can become a source of big trouble. Cardinal males are extremely aggressive, especially during the mating season. They are ready to defend their territory to the last drop of their blood - especially from their fellows. Red cardinals often smash to death on the glass of houses, mistaking the reflection in them for a rival.
