Mfiti yaku America (Anas americana) ndi ya banja la bakha, lamulo la Anseriformes.
Zizindikiro zakunja kwampikisano waku America
Mfiti yaku America ili ndi thupi lokulira pafupifupi masentimita 56. Mapikowo amatalika masentimita 76 mpaka 89. Kulemera kwake: 408 - 1330 magalamu.
Wigi yaku America ili ndi chipumi choyera. Khosi lalitali, mlomo wamfupi, mutu wozungulira. Nthenga za thupi ndizofiirira komanso zofiirira. Ndalamayi ndi yaimvi yabuluu yopyola malire akuda m'munsi mwake. Miyendo ndi yakuda imvi. Mukuuluka, "kalilole" amaonekera, mdima wokhala ndi greenish - kusefukira kwakuda. Yamphongoyo imakhala ndi nthenga yakuda yakuda ya mchira, mphumi yoyera, ndi mikwingwirima yobiriwira yobiriwira kumbuyo kwa maso mbali zamutu mpaka ku occiput.
Mwa akazi ndi mbalame zazing'ono, zizindikilo zoterezi sizimapezeka.
Masaya ndi khosi lakumtunda lokhala ndi mizere yolowa ndi imvi. Chifuwa ndi m'mbali mwake ndi zofiirira mopyola kusiyanitsa ndi mbali yakumbuyo yamtundu wakuda, ndipo mimba yoyera imawonekera kumbuyo kwa bulauni wapamwamba wokhala ndi mthunzi woyera wa nthenga zaphiko. Amuna nthawi zambiri amatha kuswana kuyambira mu Julayi mpaka Seputembara. Akazi achichepere ndi anyamata achichepere aku America amadziwika ndi mitundu yochepa ya nthenga.
Kufalikira kwa wigle waku America
Mfiti yaku America ikufalikira pakatikati pa kontinenti yaku America.
Malo okhala azinyama zaku America
Mfiti yaku America imapezeka munyanja, m'madambo amadzi, mitsinje, ndi madera olima omwe amakhala m'malire mwa nyanja. Pamphepete mwa nyanja, abakha amtunduwu amakhala m'madzi, m'mphepete mwa nyanja, amawonekera pagombe pakati pa malo okwera kwambiri komanso otsika kwambiri, pomwe masamba am'madzi amawonekera madzi akamachoka. Pakati pa nyengo yobereka, mfiti yaku America imakonda nkhalango ndi madambo omwe ali pafupi ndi minda yamitengo yonyowa. Mbalame zimasankha udzu wonyowa wokhala ndi udzu wambiri m'malo osiyanasiyana kuti apange zisa.
Makhalidwe a wig ya ku America
Wiggles aku America ndi abakha osinthasintha, amakhala nthawi yawo yambiri m'madzi, kusambira komanso kudyetsa. Mitundu ya mbalame zamtundu wa bakha sizochezeka ndipo sizimawoneka kawirikawiri, kupatula nthawi yosamukira komanso m'malo odyetserako nyama, komwe chakudya chimakhala chochuluka. Amayi aku America amagwedezeka nthawi zambiri amakhala pachisa pafupi ndi ma mallard ndi malo ozizira. Amakhala ndi gawo lamphamvu lachilengedwe: nthawi zambiri mbalame imodzi imakhala pamalo amodzi padziwe. Kuthamanga kwa wigeon waku America ndikuthamanga kwambiri, nthawi zambiri kumasakanizika ndi kutembenuka, kutsika ndi kukwera.
Kuswana ku America kumagwedezeka
Amphaka aku America ndi ena mwa mbalame zam'madzi zoyambirira zomwe zimawonekera m'malo achisanu. Kumapeto kwa nyengo yozizira, dzuwa ndi usana utachuluka, ndipo panthawiyi, kumatuluka utsi, makamaka mu February. Madeti obereketsa alibe masiku okhazikika ndipo zimadalira mtundu wa malo okhala ndi kuchuluka kwa chakudya.
Amuna amawonetsa kusambira kutsogolo kwa mkazi ndi ma jerks kumutu, mapiko m'mwamba, ndikugundana ndi bakha. Mwambo wa chibwenzi umatsagana ndi "burp," yomwe yamphongo imapanga ndikulira, ndikukweza nthenga zolimba pamwamba pamutu pake ndi thupi lake pamalo owongoka, kutsogolo kapena pafupi ndi wamkazi.
Monga abakha ambiri, oyenda ku America amawerengedwa kuti ndi mbalame zokhazokha.
Akakwatirana, amphongo amasonkhana pamodzi, kusiya akazi kuti asankhe okha chisa chawo, kuti apange malo obisika oti aziikira mazira. Mpaka kumapeto kwa makulitsidwe, ma drakes amapanga magulu pamodzi ndi akazi osaswana ndikuyamba kusungunuka. Akazi amasankha malo obisalira omwe nthawi zonse amabisika bwino mu udzu wamtali ndipo amakhala pansi patali kwambiri ndi madzi, nthawi zina mpaka 400 mita.
Chisa chimamangidwa ndiudzu, chokhala ndi masamba ndi bakha pansi. Makulitsidwe amayamba dzira lotsiriza litayikidwa ndipo nthawi zambiri limakhala masiku 25. Clutch imakhala ndi mazira 9 mpaka 12. Mkazi amatha pafupifupi 90% yanthawi ali pachisa. Amuna samachita nawo kuswana ndi kudyetsa ana. Anapiye amachoka pachisa pasanathe maola 24 kuchokera nthawi yomwe anaswa ndi bakha. Padziwe, ankhandwe amayesa kujowina ana ena, koma wamkazi amateteza izi.
Pofuna kuteteza ana awo kwa adani, abakha akuluakulu nthawi zambiri amasokoneza adani awo ku anapiye awo mwa kugwera pa phiko limodzi. Pakadali pano, anapiyewo amathamangira m'madzi kapena amathawira ku zomera zowirira. Chilombocho chikangosiyana ndi anawo, chachikazi chimauluka mofulumira. Ankhandwe amakhala odziyimira pawokha pakatha masiku 37 - 48, koma nthawi imeneyi ndi yocheperako kutengera malo okhala, nyengo, luso la bakha komanso nthawi yoswetsa.
Anapiye amadya makamaka tizilombo kwa milungu ingapo; kenako amayamba kudya zomera zam'madzi. Amayi nthawi zambiri amasiya ankhandwe asanasinthe nthenga (pafupifupi milungu isanu ndi umodzi), nthawi zina abakha akuluakulu amakhala m'malo awo mpaka molt ndikuwonekera pambuyo pake.
Kudyetsa waku America Wiggle
Malo osiyanasiyana omwe aku America amapita akamayang'ana akusonyeza mitundu yosiyanasiyana yazakudya. Mtundu uwu wa bakha umasankha posankha malo odyetserako ziweto ndikusankha malo omwe muli tizilombo tambiri komanso zomera zam'madzi. Masamba ndi mizu ndi zakudya zomwe amakonda.
Popeza ma wiggles aku America ndi osiyana siyana ndipo amasambira movutikira kuti apeze chakudyachi, amangotenga chakudya kuchokera ku mbalame zina zam'madzi:
- wakuda,
- malo,
- atsekwe,
- muskrat.
Amayi aku America amadikirira kuti mitundu iyi iwoneke pamwamba pamadzi ndi mbewu m'milomo yawo ndikudula chakudya kuchokera "mkamwa" mwawo, nthawi zina zimasefa zotsalira zomwe zimakwezedwa kumtunda ndi matumba mothandizidwa ndi lamellas omwe ali kumtunda kwa mlomo.
Chifukwa chake, abakhawa adatchedwa "osaka nyama".
Munthawi yodzala ndi kudyetsa ana, ma wiggles aku America amadya nyama zopanda madzi m'madzi: agulugufe, ntchentche za caddis ndi molluscs. Kafadala amagwidwa, koma amapanga gawo lochepa la zakudya. Abakhawa amakhala morphologically komanso physiologically kusaka kuti afufuze m'madzi. Mothandizidwa ndi mulomo wamphamvu, ma wigeon aku America amatha kudula zidutswa zazikulu kuchokera pagawo lililonse la chomeracho, kudya zimayambira, masamba, mbewu ndi mizu.
Pakusamuka, zimadya msipu m'mapiri okutidwa ndi clover ndi zomera zina zouma, ndipo zimayima m'minda ndi mbewu zina.
