KItaran hidup Burung Layang-layang GUa

Ingin tahu tentang kitaran hidup burung layang-layang gua ini?

Burung layang-layang membiak disepanjang tahun tetapi kebanyakkannya lebih tertumpu kepada bulan Oktober hingga Februari. (musim hujan di mana lebih banyak serangga boleh didapati. KENAPA? Masa ini lebih sesuai membesarkan anak kerana tak susah mencari makanan. Ibu dan bapa sama-sama keluar mencari makan untuk membesarkan kedua-dua anak. Kawasan mencari makanan lebih dekat dan anak tak perlu ditinggalkan lama di sarang..TANPA PENJAGAAN!!

MASA PENGERAMAN ialah untuk selama 23 hari + n - dan masa diambil untuk membesar ialah 43 hari + n - juga.

Swiftlets are insectivores; hymenopterans and dipterans being the most abundant prey (Lourie & Tompkins, 2000). Typically, they leave the cave during the day to forage and return to their roost at night. Males and females look similar; as usual in such cases, these birds are monogamous and both partners take part in caring for the nestlings. Males perform aerial displays to attract females and mating occurs at the nest. The breeding season overlaps the wet season, which corresponds to an increased insect population. Clutch size depends on the location and the food source, but it is generally not large; Aerodramus swiftlets lay 1-2 eggs. The eggs are a dull white color and are laid every other day. Many if not all species are colonial nesters; some build their nests in high, dark corners on cave walls. Swiftlets in temperate zones do migrate but, most Aerodramus swiftlets live in the tropical Indo-Pacific region and do not migrate. These birds usually remain in one cave or other roosting/nesting site. Some examples of caves include the Niah Caves at Niah National Park & Gunung Mulu National Park which are all located in Sarawak, Malaysian Borneo.
