The Swiftlet Condo, known as the "Golden Swallow" of Pak Phanang, originally saw edible-nest swiftlets inhabit a two-story wooden house along the banks of the Pak Phanang River in 1943. Over time, their population spread to a three-story building featuring "Sino-Portuguese" architecture, the first and only of its kind in the Pak Phanang market. They then migrated to the tunnels beneath the Wat Kongkhasuwat temple and today are found throughout the town. This thriving population is attributed to the area's rich environment, which has allowed the swiftlets to increase in number rapidly. An additional 250 high-rise buildings have been constructed to provide nesting sites for these birds, encouraging them to cling to walls and wooden panels. The ideal habitats for these swiftlets include offshore islands, coastal areas, and towns near rivers, particularly those with healthy mangrove forests that serve as a food source rich in small insects. When it's time to lay eggs, the birds begin constructing their nests by extracting materials from their salivary glands—a process that takes about 30 to 35 days. After laying their eggs, the young birds eventually gain strength and learn to fly. Once they leave the nest, these nests are harvested and sold, as they are believed to greatly nourish the body. The price of bird nests varies significantly depending on quality; one kilogram typically contains 80 to 85 complete nests. Furthermore, processed edible bird nests are available for consumption in Pak Phanang and are also exported to various provinces and international markets.
