IDerbnik yinkozi encane efana nejuba. Izinyoni azivamile; zizalela ezindaweni ezahlukahlukene ezindaweni ezivulekile e-Alaska, eCanada, enyakatho nasentshonalanga ye-United States, eYurophu nase-Asia, futhi zihlala ezindaweni ezisemadolobheni nasemadolobheni.
Ukubukeka kukaMerlin
Mikhulu kancanyana kunama-kestrels. Njengamanye ama-falcons, anezimpiko nemisila emide, emincane, futhi andiza ngenkuthalo ngamaphiko amafushane, anamandla, afana ne-piston. Ngokungafani namanye ama-falcons, i-merlin ayinalo uphawu lwamadevu emakhanda abo.
Abesilisa nabesifazane nabameleli be-subspecies bahlukile komunye nomunye. Abancane bobulili bobabili bafana nabesifazane abadala. Abesilisa abanemihlane namaphiko aluhlaza okwesibhakabhaka kanye namaphiko, imisila emnyama enemigqa emi-2-5 ezimpunga ezacile Engxenyeni engezansi yomzimba kunemivimbo emnyama, izindawo ezibomvu ezinhlangothini zesifuba. Abesifazane banemhlane onsundu onsundu, izimpiko nemisila enemivimbo emincanyana enombala ophuzi. Ngezansi komzimba kunenyathi enemibala enemivimbo. Abesifazane bakhulu cishe ngo-10% kanti u-30% usinda.
Izici zokuzala ze-merlin
Njengomthetho, izinyoni zihlala zodwa. Amalungu ngababili achitha ubusika ngokwehlukana, futhi entwasahlobo ngayinye kwakheka isibopho samabhangqa amasha noma elidala liyabuyiselwa. UMerlin ubuyela endaweni efanayo yokuzalanisa, uhlala endaweni efanayo yokwakha izidleke. Amasokhethi awaphindi asetshenziswe.
Izinyoni "ezisebenza kanzima"
Abesilisa babuyela ezindaweni zokuzalela inyanga ngaphambi kwabalingani. Kwezinye izimo, abesifazane bahlala endaweni yokuzalanisa unyaka wonke. I-Merlin ayakhi, isebenzise izidleke ezilahliwe zezinye izinyoni, izilwane ezidla ezinye noma izibungu. Lolu hlobo futhi luhlala emaphethelweni emadwaleni, emhlabathini, ezakhiweni nasemigodini yezihlahla. Lapho ubekwa emadwaleni noma phansi, funa ukucindezeleka bese ukusebenzise ngokwengeza utshani obuthile.
UMerlin onamachwane
Imidanso yomoya
Amabili abumba inyanga eyodwa kuya kwezimbili ngaphambi kokubeka. IMerlin ikhombisa izigaxa zasemoyeni, kufaka phakathi ama-wing-banging nama-side-to-side roll aheha abesifazane futhi ethuse amanye amaduna. Womabili amalungu alaba bobabili ahamba futhi "ahamba kancane" ukuchaza indawo yabo. Ukundiza okundizelayo kulapho amaduna endiza kancane ngamaphiko amafushane, angajulile wamaphiko awo esiyingini noma abalwa ayisishiyagalombili eduze komlingani ohlezi phansi.
Ama-Merlniks abekela amaqanda ayi-3-5. Uma i-clutch ifa ekuqaleni kwenkathi yokwakha isidleke, insikazi yenza i-clutch yesibili. Abesifazane basebenzisa iningi lezinsuku ezingama-30 ekufukameleni. Ngemuva kokuchamisela, umama uhlala ngokuhlala namaphuphu izinsuku eziyi-7. Lapho izingane zifinyelela eminyakeni yobudala okungenani evikini, omama bahlala nazo kuphela esimweni sezulu esibi.
Phakathi naso sonke isikhathi, owesilisa uhlinzeka amaphuphu nokudla kwawo ngokudla. Ngesikhathi sokufukamela, abesilisa bayafukamela amaqanda kafushane, abesifazane badla eduze. Ngemuva kokuchanyuselwa, abesilisa babiza abesifazane, ababuyeli esidlekeni, abesifazane bayandiza ukuyofuna ukudla kwamachwane kumlingani wabo. Amachwane ayazibophezela lapho enezinsuku ezingama-25 kuya kwezingu-35 ubudala. Emasontweni amabili ngemuva kwamaphiko, ama-merlins amancane abamba izinambuzane ngokwawo, yize zihlala zincike kubazali bazo cishe amasonto ama-5 ngemuva kokubaleka.
Izici zokondla ama-merlins
Izinyoni zizingela, zihlasela izisulu ezivela emagatsheni nasezindizeni, zisebenzisa amagquma nezinye izici zezwe ukusithela ngasese kisisulu. IDerlniks ayihlaseli isukela ezindaweni eziphakeme kakhulu. Umsebenzi wokuzingela ubonwa ekuseni kakhulu nantambama.
Abesilisa bagcina ukudla okweqile eduze kwesidleke, kanti abesifazane badla lapho owesilisa ephuze ukubamba inyamazane. Ukudla kukaMerlin ngamajuba, amadada amancane, izinyoni zezingoma ezincane nezincane. Ezindaweni zasemadolobheni, ondlunkulu yibo abadla kakhulu i-merlin. Lezi zinhlobo ziphinde zidle izinambuzane, izilwane ezincelisayo ezincane, izilwane ezinwabuzelayo nezilwane eziphila ezweni.
