[[thanhphongthudao]] There are many different types of swiftlets, and the way they build their nests is also different: some make their nests with feathers, others make their nests with grass or straw, only two types of swiftlets, Aerodramus fuciphagus and Aerodramus maximus, make their nests with saliva, and only this type of nest can be used as food. Swiftlets start building nests during the breeding season (from late March to mid-May), and the nests are built in about 33 - 35 days. The nests are built in the shape of bowls and are attached to the walls of caves (or walls, beams). The nests consist of many thin sheets woven from many silk threads of swiftlet saliva intertwined. After building the nests, swiftlets begin to mate and lay eggs, swiftlets usually lay 2 eggs, 1 - 4 days apart. The eggs hatch after 22 - 26 days, and the chicks leave the nest when they are about 40 - 45 days old. During this time, both the father and mother birds take turns incubating the eggs and foraging for food to feed their young. http://lizinkom.ruwww.webmail.onlineboxing.net/jforum/user/edit/351033.page https://talk.plesk.com/members/tamkhoe.396474/ https://tamkhoe.ucoz.net/ http://www.effecthub.com/user//showfollowers/3778726 https://www.producthunt.com/@tamkhoe https://nativ.media/wiki/index.php?operaswing51 https://considerate-freesia-nqpfj8.mystrikingly.com https://forumketoan.com/members/tamkhoe.20659/ https://muabanvn.net/ https://cungvuichoi.com/members/tamkhoe.11839/#recent-content https://kenhrao.com/members/tamkhoe.75439/ https://diendan24h.com/members/tamkhoe.10756.html https://diendan.chicucthuy.com/members/tamkhoe.12359/ https://diendan.thoitrangngaynay.com/members/tamkhoe.757/ https://mienphi.us/members/tamkhoe.10455/ https://raovat.trumbansi.net/threads/gioi-thieu-ve-yen-sao-tam-khoe.25642/ https://forum.codeigniter.com/member.php?action=profile&uid=150310 https://forum.truongtin.top/members/tamkhoe.1587/ http://80.82.64.206/user/tamkhoe https://raovat49.com/member/posts-by-1132316 http://tamkhoe.vn https://yensaotamkhoe.blogspot.com
