MeskipunUlar dapatterbang sebenarnya tidak benar-benar "terbang" seperti burung, namunmelainkan ularhanya inimeloncat dari dahan pohon ke dahan pohon lain. Ular inipun hanya melakukannya ketika mencari mangsa atau menghindari bahaya. Sebelum berpindah, seekor ular terbang akan memanjat ke dahan yang tinggi, lalu mencarimenuju ujung ranting pohon yang terbuka. Setelah berada di ujung ranting, ular ini melengkungkan badannya membentuk huruf "S", kemudian mendorong tubuhnya ke depan. Begitu terjun dari dahan, ular ini segera memipihkan badannya dan meregangkan tulang iganya, tujuannnya untuk memperlambat kecepatan jatuh badannya. Saat meluncur, ular ini menggerak-gerakkan kepala dan ekornya ke kanan dan ke kiri untuk mengarahkan tubuhnya ke dahan pohon yang dituju. Ketika akan mendarat, ular ini memindahkan bagian belakang tubuhnya ke bawah untuk mempermudah pendaratan, lalu dengan segera mengembalikan regangan badan dan tulang iganya seperti semula. Begitu mendarat di ranting, ular ini langsung menormalkan badannya kembali, sehingga ular ini pun bisa bergerak di pohon seperti biasabiasanya.<ref name="archipelago" /><refnovelty>{{cite webjournal |last=SochaDudley |first=R |last2=Byrnes |first2=G. |last3=Yanoviak |first3=S.P. |last4=Borrell |first4=B. |last5=Brown |first5=R.M. |last6=McGuire |first6=J.A. |year=2007 |title=FlyingGliding Snakeand the Functional Origins of Flight: Biomechanical FrequentlyNovelty Askedor QuestionsNecessity? |journal=Annual Review of Ecology, Evolution, and Systematics |volume=38 |pages=179–201 |url=http://www.flyingsnakenhm.ku.edu/rbrown/Rafes%20PDF%20publications/Dudley.etal.flight.annurev.pdf |accessdate=2009-07-14 |doi=10.1146/annurev.ecolsys.37.091305.110014 |archive-url=https://web.archive.org/faqsweb/faqs20110112101715/http://www.htmlnhm.ku.edu/rbrown/Rafes%20PDF%20publications/Dudley.etal.flight.annurev.pdf |archive-date=19992011-200501-12 |publisherurl-status=dead }}</ref><ref>{{cite journal|last=Jayne |first=flyingsnakeB.C.org |date=December 1986 |title=Kinematics of Terrestrial Snake Locomotion |journal=Copeia |volume=4 |issue=4 |pages=915–927 |url=http://bioweb.ad.uc.edu/faculty/jayne/pubs/bcjpub05.pdf |accessdate=2009-07-15 July|doi=10.2307/1445288 |url-status=dead |archiveurl=https://web.archive.org/web/20061030125125/http://bioweb.ad.uc.edu/faculty/jayne/pubs/bcjpub05.pdf |archivedate=October 30, 2006 |jstor=1445288 2009}}</ref><ref Ularname=paradise>{{cite inijournal juga|last=Socha sering|first=J.J. berada|date=August dekat2002 dengan|title=Kinematics manusia,- danGliding akanflight menggigitin jikathe tergangguparadise tree snake|journal=Nature |volume=418 |pages=603–604 |url=http://www.esm.vt.edu/~jjsocha/Publications_list_files/Socha_2002.pdf Meskipun|accessdate=2009-07-14 begitu,|doi=10.1038/418603a racun|pmid=12167849 ular|issue=6898 ini}} hanya{{Dead berbahayalink|date=October bagi2010|bot=H3llBot}}</ref><ref mangsanyaname=volunteer>{{cite danjournal tidak|last=Wei berbahaya|first=C. bagi|date=May manusia2005 |title=Inside JEB - Snakes take flight |journal=The Journal of Experimental Biology |volume=208 |issue=10 |pages=i–ii |url=http://jeb.biologists.org/content/208/10/i.2.full |doi=10.1242/jeb.01644}}</ref>
