What are the different kinds of Edible Bird’s Nest?

Depending on the country of origin, Edible Bird’s Nest can be graded and categorized using differing systems. However, all can be divided into 3 main types, by its natural color:
- Red (blood) Nests - most expensive
- Pink/Orange Nests
- White Nests - least expensive

What are the different kinds of Edible Bird’s Nest?

Red (blood) Nest

A misconception is that red (blood) nests are from the bird’s blood, and have higher nutritional value. In fact, analysis has shown no traces of blood in these nests, and the color of the nest is a result of oxidation of the nest and reaction to content in the air over prolonged periods of time, and absorption of minerals from stones that make up cave walls. All nests are made from secretions in the bird’s saliva glands, and starts out as white nests, then in specific conditions, may oxidize, react, and change color. Cave nests vary slightly in texture, and is most expensive due to limited supplies and the high cost of harvesting, as it is extremely dangerous for humans to access these cave walls. The loss of lives from harvesting cave Edible Bird’s Nest is not uncommon.

Pink / Orange Nest

Similar to red nests, pink and orange nests start out as white, and over time react with the surrounding environment and changes color but to a lesser extent than red nests. Nests that have been used multiple times for hatching and remain un-harvested over multiple hatching seasons are likely to change in color, density, weight, and size. Those who prefer Edible Bird’s Nest that are highly-textured, dense and rich in flavors often seek pink and orange nests.

White Nest

White nests, being most abundant, are more economical to consume, and with the same nutritional value, is the usual nest of choice for the majority of people. Some also prefer the simple, white color to eliminate the possibility of consuming manufactured, color-treated nest, which is a real risk. White nests also give a feeling of purity, and in some cases white nests that are harvested early, before eggs are laid, have a high demand and market value.
Pink/Orange nests and white nests can come from both caves and birdhouses, but Red (blood) nests are exclusive to only cave environment. Red (blood) nests sourced from birdhouses should be avoided, as it is a result of human intervention to intentionally modify the color by many methods and unethical means. Consumption of these treated nests is a health hazard and should be avoided.
