Yen island, Quy Nhon province is a wonderful landscape with caves of ten thousands of years and stone blocks in hundreds of meters in high. The bed of cave is large but full of obstacles and difficult of access, it becomes the best places for swallow to make their nests. In Yen Island, there remain 30 small and large caves, mainly located in two villages of Nhon Hai and Nhon Ly. Every year, people may collect from 100 to 300 swallow nest in as small cave. For the large caves, especially, the caves with their gates toward the East or Southeast, with cool and airy spaces and the fresh water remaining in the ceiling, the floating waves in the sea, local people may collect fourteen or fifteen thousand nests per years. There are two main types of swallow in Yen Island, Quy Nhon namely yen co and yen sao.
The body of yến cỏ is larger than that of yến sào, and its nest is made by grass or rubbish taken from the mountains. Yen sao is the precious bird. The body of this bird is small but it can fly strongly. It takes the food by flying over the sea. It can fly for ten hours without any stop. Its nest is not made by grass but by its own slaver. Day by day, it pours a little of slaver, stretching it into cord and rolling it into the nest. For a time, the nest is dry and looks like a helix strongly fixed onto the ceiling or cliff. As the nest is large enough for the body, it starts reproducing.
To take the nests in the cliff and cave ceiling, people often use the bamboo-made scaffolds. People can travel in the scaffold as in a bridge. Some caves are in very high position so that people use up to 300 bamboo trees to make scaffold. The pillars are made of four or five trees to reach the ceiling. The way to take the nest is very meticulous. Any nest is far from the reach, people use a stick with a dog-nail on the top to take the nest. In the dry weather, before taking the nests, the local people use water injecting into the nest for softening to avoid breaking the nest.
The breeding season of swallow is January and February of lunar calendar and one month later is suitable time to take the first crop. The second one is when the birdies become strong enough to fly for seeking their food. People may collect a little quantity in the third crop. This time is a mainly creating favorable condition for sallow developing the quantity. Sallow nests are the export article of high economic value in Bình Dinh Province.
