[ About Us and Our Swiftlets ] Swiflets Characteristics Figure 2: Corner-shaped Bird Nest Figure 3: Cup-shaped Bird Nest Figure 4: Natural White Bird Nests In early morning, the swiftlets will leave their nests to find food and return in the evening. Since house nest habitat conditions are better than in harsh natural caves, their nests contain less feathers, less impurities, generally cleaner and have higher swelling capacity. During good weathers and foods are plentiful, the quality of the strands of saliva are thick, contain less dirt particles and have high swelling capacity. Hence, the price will be more expensive. Other times, during dry season, the quality of the nest would have more feathers, contain more dirt particles and low swelling capacity. This is mainly attributed to scarced food supply and their low secretion of saliva. |
