Cook Islands #479 (1977) – Silver Coin

The $5 Cook Islands coin featuring Swiftlets on the reverse side is part of a series of coins issued by the Cook Islands. Swiftlets are small birds known for their aerial acrobatics and their ability to navigate through dark caves using echolocation.

One of the most interesting aspects of swiftlets is their use of saliva to construct their nests. Swiftlet nests are made primarily of strands of saliva, which harden upon exposure to air. These nests are often built in dark, humid environments, such as caves or the interiors of buildings. The nests are small, cup-shaped structures, and they are prized for their culinary and medicinal properties.

Edible bird’s nests, as they are commonly known, have been consumed for centuries, particularly in Chinese cuisine. They are highly valued for their supposed health benefits and unique texture. Edible bird’s nests are believed to promote good health and longevity, and they are often consumed as a delicacy or used in traditional Chinese medicine.

In recent years, the demand for edible bird’s nests has increased, leading to concerns about overharvesting and the sustainability of swiftlet populations. In response, there have been efforts to regulate the harvesting of bird’s nests and promote sustainable practices.
