Bird Oddities and Wonders

From this long list, we have chosen for you the strangest birds and some information about them:

The ostrich egg is the largest egg in the world of birds and weighs 2 kilograms and its shell is 1.5 mm thick and can carry a weight of 125 kg. The smallest egg is that of the hummingbird, which is no more than 4 cm long and weighs only one gram. It is the only bird that can fly backwards but cannot walk, and the same applies to kingfishers, grebes and divers.
The penguin can swim but cannot fly at all, as it can glide underwater easily and maneuver for a full hour.
One of the strange things about birds is their hollow bones. The weight of the bones is less than the weight of their feathers, which helps them fly and reduces their weight.
The chickadee is an intelligent bird, and it is those singing birds smaller than the sparrow, and it is characterized by joy and innocence, however, these small birds must be reconsidered because they are not as we think, as it has been observed that the chickadee bird enters hollow trees and beats bats to death and then drags them to eat, and this happens specifically during the height of winter when there is a shortage of food, so the chickadee birds enter the caves used by bats during hibernation periods, and kills them by attacking their exposed heads, and from this behavior it is clear that in difficult times, birds will do what they have to to survive, and also this predatory behavior of this delicate bird proves that many strange secrets can be hidden behind an innocent appearance.
