chamagaadad aakaash mein udne wala ek stanadhaari praani hai, jo apni 1000 se bhi adhik prajaatiyon ke saath stanadhaariyon ke doosare sabse bade kul ka nirmaan karta hai.[1] ye poorn roop se nishaachar hote hain aur pedon ki daali athva aaindheri gufaaon ke andar ulta latake rahate hain.[2] inko do samoohon me vibhaajit kiya jaata hai, pehla samooh falabhakshi bade chamagaadad ka hota hai, jo dekh kar aur soongh kar apna bhojan dhoondhate hain jabki doosra samooh keetabhakshi chhote chamagaadad ka hota hai, jo pratidhvani dvaara sthiti nirdhaaran vidhi ke dvaara apna bhojan talaashate hain. yeh ekamaatr aisa stanadhaari hai jo ud sakta hai tatha raat mein bhi ud sakta hai. iske agrabaahu pankh me parivrtit ho gaye hain jo dekhne mein jhilli (petaajiym) ke samaan lagte hain. tvacha ki yeh jhilli garadan se lekar haath ki aainguliyon tatha shareer ke paarshvabhaag se hoti hui pooainchh tak chali jaati hai evam pankh ka nirmaan karti hai. pichhli taaaingein patali, chhoti aur nakhayukt hoti hain. iske shareer par baal kam hi hote hain. sir ke donon or bade-bade karnapallav paaye jaate hain. chamagaadad ke pankho ka aakaar 2.9 senteemeetar se lekar 1500 senteemeetar tak tatha inka vajan 2 gram se 1200 gram tak hota hai.[3]

chamagaadad ulate latakate hain kyon ki ulte latake rahane se ve badi aasaani se udaan bhar sakte hain. pakshiyon ki tarah ve jameen se udaan naheen bhar paate, kyonki unke pankh bharpoor uthaan naheen dete aur unke pichhle pair itne chhote aur aviksit hote hain ki vo daud kar gati naheen pakad paate. chamagaadad aamtaur par andheri gufaaon mein dinbhar aaraam karte hain, sote hain aur raat ko hi nikalte hain. ye sote hue gir kyon naheen jaate iska kaaran ye hai ki chamagaadad ke pairon ki nasein is tarah vyavasthit hain, ki unka vajn hi unke panjon ko majbooti ke saath pakadne mein madad karta hai.[4]
