Why are mangrove forest important?
Mangroves provide valuable nursery areas for juvenile fish and crustaceans and are also important source of nutrients for the adjacent marine ecosystem. Mangrove made shelter and food possible for animals living there. Most importantly, Mangroves helps to protect the coastline from serious erosion during tropical cyclones.

Why mangroves are able to protect humans being!?
Mangroves form dense barriers against storms and tsunamis, saving lives and protecting property. They also provide us with many other important benefits—more than many people may realize. For example, mangroves produce seafood, fruits, medicines, fiber, and wood. They stabilize shores by trapping sediments and building land. They improve water quality by filtering runoff and polluted waters. They protect the climate by absorbing carbon dioxide and reducing the amount of greenhouse gas

Cuckoos are birds of the medium size. They can reach 12.6 to 14.1 inches in length and weight up to 2.1 ounces.
Cuckoo has long and pointed wings and long and thin beak. While flying, it resembles to hawk.
Cuckoos are named after onomatopoeic sound which they produce: 'cuck-oo, cuck-oo'. Even thought the whole family is named by this unique sound, only one cuckoo species (Common cuckoo) is able to produce this sound. Other species communicate by producing different types of sounds.
Characteristic 'cuck-oo, cuck-oo' sound is produced only by males. Females produce bubbling sound, which resembles the sound of the water that is running out of the tub after removing the plug.
Cuckoo feeds on insects and its favorite food is hairy caterpillar.
Cuckoo travels to Africa each September to avoid cold periods and lack of food during the winter in temperate areas of Europe and Asia.
Although cuckoo spends almost nine months in Africa, it never sings while there.
Cuckoo does not build its own nests, because it is a brood parasite. That means that female cuckoo uses nests of other birds to lay her own eggs.
More than 120 species of birds can be tricked to raise young cuckoos as their own chicks, but 90% of cuckoo's eggs are laid in the nests of reed warbler, meadow pipit and dunnock birds. Cuckoo chooses nests with eggs that are the most similar to eggs that she is producing.
20% of cuckoo's eggs will be recognized as foreign eggs and eliminated from the nest.
Female cuckoo lays one egg in each nest. She usually lays between 12 and 22 eggs per season (in 12 to 22 different nests).
Timing of the hatching is very important and female cuckoo closely observes routine and behavior of other birds. Cuckoo's eggs need to hatch before other eggs so that the young cuckoos gain advantage over other chicks and ensure enough food for development.
Young cuckoos are very aggressive toward other chicks in the nest and they will often remove them from the nest as soon as they hatch. When they are several weeks old, young cuckoos are ready to fly to Africa along with their parents.
Cuckoos live less than six years in the wild.
Cuckoos have played a role in human culture for thousands of years, appearing in Greek mythology as sacred to the goddess Hera. In Europe, the cuckoo is associated with spring, and with cuckoldry, for example in Shakespeare's Love's Labours Lost. In India, cuckoos are sacred to Kamadeva, the god of desire and longing, whereas in Japan, the cuckoo symbolises unrequited love.
