Ngakhale dzina lake, nighthawk si nkhanu konse, koma ndi membala wa banja la nightjar. Mbalameyi imadziwika chifukwa cha mayendedwe ake apamlengalenga komanso mawu omveka bwino, zomwe zimapangitsa kuti ikhale mbalame yodziwika bwino pakati pa owonerera mbalame komanso okonda zachilengedwe.
Malo a Common Nighthawk

Mbalame yotchedwa nighthawk imakonda malo otseguka, monga madera a udzu, madambo, ndi zipululu, koma imapezekanso m'matauni, momwe imakhalira padenga lathyathyathya ndi nyumba zina zazitali. Ndi zamoyo zausiku, kutanthauza kuti zimagwira ntchito kwambiri usiku ndipo nthawi zambiri zimawoneka zikuuluka mozungulira magetsi a mumsewu ndi magwero ena a kuwala kochita kupanga.
Maonekedwe Athupi a Common Nighthawk
Mbalame yotchedwa nighthawk ndi mbalame yapakatikati, yomwe imakhala pakati pa mainchesi 8 ndi 10 m'litali ndi kulemera pakati pa 2 ndi 3 ounces. Ili ndi mawonekedwe otalikirapo okhala ndi mapiko otakata mpaka mainchesi 24, zomwe zimapangitsa kuti izichita modabwitsa.
Nthenga za nighthawk zili ndi nthenga zofiirira komanso zotuwa zomwe zimabisala bwino kwambiri pozungulira. Ili ndi mlomo waufupi, waukulu komanso maso akulu, akuda omwe amaupangitsa kuwona bwino usiku.
Zakudya ndi Zakudya Zodyera za Common Nighthawk
Mbalame yotchedwa nighthawk ndi tizilombo towononga, kutanthauza kuti imadya tizilombo. Imakonda kwambiri njenjete, kafadala, ndi nyerere zouluka, zomwe imagwira m’mlengalenga pogwiritsa ntchito kamwa lake lalikulu, losanja.
Mbalame yotchedwa nighthawk ndi yaluso mlenje wa m’mlengalenga ndipo nthawi zambiri imatha kuwonedwa ikuuluka mozungulira nyali za mumsewu ndi malo ena opangira kuwala, komwe kumakopeka ndi tizilombo. Imadziwikanso kuti imachita kadyedwe kapadera kotchedwa "hawking," komwe imawulukira cham'mbuyo mozungulira, imagwira tizilombo pamapiko.
Kuswana Makhalidwe a Common Nighthawk
Ng'ombe yotchedwa nighthawk ndi yoweta yokhayokha yomwe imapanga awiriawiri amtundu umodzi panthawi yoswana. Nthawi zambiri zimaswana m'malo otseguka, monga nkhalango ndi udzu, pomwe zimamanga chisa chosavuta pansi kapena pamalo athyathyathya, monga padenga kapena msewu wamiyala.
Nsomba yaikazi imaikira dzira limodzi kapena awiri, lomwe limatalikirana pafupifupi milungu itatu. Anapiye amabadwa ali ndi nthenga zotsika ndipo amatha kuchoka pachisa pakangopita masiku ochepa. Makolowo amapitiriza kudyetsa ndi kusamalira anapiyewo mpaka atakwanitsa kudzisamalira okha.
Njira Zosamuka za Common Nighthawk
Mbalame yotchedwa nighthawk yomwe imasamukasamuka imene imakhala ku South America m’nyengo yozizira ndipo imabwerera kumene imaswana ku North America m’miyezi yachilimwe. Amadziwika ndi maulendo ake aatali, omwe amasamukasamuka, omwe amatha kuyenda mtunda wa makilomita 5,000.
Mbalame yotchedwa nighthawk nthawi zambiri imasamuka usiku, pogwiritsa ntchito nyenyezi ndi mphamvu ya maginito yapadziko lapansi poyenda. Imasamuka yokhayokha, kutanthauza kuti siyenda m’magulu ngati mbalame zina.
Zolemba za Common Nighthawk
Mbalame yotchedwa nighthawk imadziwika chifukwa cha mawu ake apadera, omwe amaphatikizanso kuyimba kwa m'mphuno ndi mawu oti "boom". Mbalame yotchedwa nighthawk imagwiritsa ntchito maitanidwe amenewa pofuna kukopa zibwenzi zake ndi kukhazikitsa malo awo panthawi yoswana.
Mbalame yotchedwa nighthawk imadziŵikanso ndi mapiko ake oombera m’mwamba mwapadera, pamene imaulukira m’mwamba n’kudumphira m’munsi, n’kumapanga phokoso loomba m’mwamba ndi mapiko ake. Chiwonetserochi chikuganiziridwa kuti ndi chikhalidwe chomwe chimathandiza kulamulira amuna ena.
Zowopsa kwa Common Nighthawk Population
Chiwerengero chofala cha mbalame za nighthawk pakali pano chikuwoneka ngati chokhazikika, koma chikukumanabe ndi ziwopsezo zingapo. Kuwonongeka kwa malo okhala, komwe kumachitika chifukwa cha kukula kwa mizinda, ulimi, ndi nkhalango, ndizo zomwe zikuwopseza kwambiri moyo wa mbalamezi.
Ziwopsezo zina ndi monga kugundana ndi nyumba ndi magalimoto, kudyetsedwa ndi amphaka apakhomo ndi zilombo zina, komanso kukhudzana ndi mankhwala ophera tizilombo, zomwe zingachepetse kuchulukana kwa mbalame za nighthawk.
Kuyesetsa Kuteteza kwa Common Nighthawk
Pali zoyesayesa zingapo zoteteza mbalame zamtundu wa nighthawk ndi malo ake okhala. Zinthuzi ndi monga kuteteza malo ofunika kwambiri obereketsa zisa ndi zisa, kukhazikitsa mapulani omangira mbalame mosavuta komanso kuchepetsa kugwiritsa ntchito mankhwala ophera tizilombo m’madera aulimi.
Mbalame ya nighthawk imatetezedwanso pansi pa lamulo la Migratory Bird Treaty Act, lomwe limaletsa kuvulaza kapena kupha nyamayo popanda chilolezo.
Udindo wa Common Nighthawk mu Ecosystems
Nsomba wamba wa nighthawk amagwira ntchito yofunika kwambiri pazachilengedwe monga nyama yodya tizilombo, zomwe zimathandiza kuwongolera kuchuluka kwa anthu. Ilinso mtundu wowonetsa, kutanthauza kuti kupezeka kwake kapena kusapezeka kwake kungagwiritsidwe ntchito kuyesa thanzi la chilengedwe.
Kuonjezera apo, nighthawk ndi chizindikiro chofunika kwambiri cha chikhalidwe, chokhala ndi nthano zambiri komanso nthano zozungulira m'zikhalidwe zambiri za Amwenye Achimereka.
Kale ndi Chikhalidwe Kufunika kwa Common Nighthawk
Nkhuku wamba wamba wachita mbali yofunika kwambiri pa nthano ndi nthano za zikhalidwe zambiri za Amwenye Achimereka. M'mafuko ena, nighthawk amakhulupirira kuti ndi mtetezi ndi mthenga, pamene ena amawoneka ngati chizindikiro cha mphamvu ndi kulimba mtima.
Kuphatikiza apo, kasewero kakang'ono ka nighthawk komanso mawu ake apadera apangitsa kuti ikhale nkhani yotchuka kwambiri pazaluso ndi zolemba, ntchito zolimbikitsa za akatswiri ojambula ndi olemba m'mbiri yonse.
Kutsiliza: Zosangalatsa Zokhudza Common Nighthawk
Mbalame yodziwika bwino ya nighthawk ndi mbalame yochititsa chidwi yomwe ili ndi mawonekedwe apadera komanso machitidwe. Kuchokera ku nthenga zake zooneka ngati zing'onozing'ono komanso zochititsa chidwi za m'mlengalenga mpaka kamvekedwe kake kosiyana ndi kamvekedwe kake komanso ntchito yofunika kwambiri pazachilengedwe, nighthawk ndi zamoyo zomwe zikupitilizabe kukopa ndi kulimbikitsa owonerera mbalame komanso okonda zachilengedwe padziko lonse lapansi. Mwa kuchitapo kanthu kuti titeteze malo ake okhala ndi kusunga anthu ake, tingatsimikizire kuti mbalame zochititsa chidwizi zikupitirizabe kukula kwa mibadwomibadwo.
