The season when the kingfisher nests along Tri An Lake.

For about a month now, a series of oarfish nests have appeared, hanging precariously from trees along the banks of Tri An Lake, in the section passing through Tri An commune, Dong Nai province, creating a unique scene that attracts everyone's attention.

At this time of year, the small, graceful-flying dragonfly is entering its breeding season. They choose tall trees along the lake's edge or amidst clumps of wild grass and reeds to build their nests.

Unlike other birds that build just one nest, the dragonfly meticulously constructs two nests close together. One nest serves as a courtship site to attract a mate, while the other is used for laying eggs, incubating, and raising its young.

Each male bird meticulously cares for its nest, a process that takes about 20 days. They use blades of grass and leaves, separating them into thin strands and stacking them perfectly to form a thick nest.

The common rail typically builds its nest high up, with the entrance facing upwards, to avoid rain and protect the eggs and chicks from predators such as snakes, lizards, and rats. This nest-building method is crucial for their reproduction.

These dragonfly nests are not simply places for breeding, but also unique structures in terms of scientific design, functionality, and artistic value, showcasing the ingenuity of this skillful bird species.

The Oriental stork is a wild bird with unique breeding habits and nest-building techniques, contributing to the richness of the ecosystem around Tri An Lake. Therefore, locals and tourists visiting Tri An Lake must absolutely refrain from hunting, destroying nests, and disturbing their natural habitat.
