How does rhododendron breed?

Rhododendrons are solitary and solitary. It doesn't nest, it doesn't hatch, and it doesn't hatch. Interestingly, they can also reproduce. It turns out that the female cuckoo is always looking for nests of yellowbird, lark and sparrow. Before laying eggs. Once the old bird leaves the nest, it lays eggs in other people's nests, and then takes away the title of nest owner and lets the nest owner hatch eggs for him.

Rhododendron has formed a set of skills in its long-term survival and evolution. The cuckoo's eggs are exactly the same as those in the nest it occupies in color, size, spots and patterns. Therefore, the little cuckoo's "mom and dad" are always cheated and raised as their own children. Little cuckoos always hatch before the children of righteous relatives. Within 30 hours after birth, it will push other eggs out of the nest. Poor "parents" don't know that their children are suffering, but they still take good care of the "only child" in the nest. When the little cuckoo is full of feathers, it will fly away with its "biological mother" who is active nearby.
