Germain's Swiftlet was at the time regarded as conspecific Along with the Edible-nest Swiftlet but has become normally acknowledged to be a separate species. It can be distinguished by its array and some delicate morphological dissimilarities.
They forage during the day and capture aerial insects by sight like other swiftlets, but to return on the caves for roosting/breeding, they use their echolocation talents. Edible-nest swiftlets arise from their roosting caves at dawn and return for roosting at dusk.

), are bred in captivity inside of a specifically developed creating that isn't their pure habitat, which may have an impact on their dietary behaviors.three Even though swiftlets tend not to essentially select nutritionally ample diets, some primary nutrients, like carbohydrates and fats, are crucial as energy sources, and proteins are necessary for tissue and enzyme development and for expansion. Minerals are also required: calcium is needed by reproductively active female birds for egg generation, and phosphorus is required in huge portions for bone design.
