Nyevedzi yedanga ishiri inobva kumhuri yenyenganyenga.
Mhuri iyi inosanganisira makumi mapfumbamwe emarudzi eshiri kubva ku90 genera. Kune masere subspecies of swallows, imwe neimwe inogara munzvimbo dzakasiyana dzepasi.
2
Inogara makondinendi ese kunze kweAntarctica.
Nzvimbo dzekuberekesa dzebarn swallows dziri kuchamhembe kwehemisphere, uye nzvimbo dzechando dzakatenderedza equator uye kumaodzanyemba kwehemisphere. MuAustralia, inotonhora chete munzvimbo dziri kumahombekombe ekuchamhembe kwekondinendi.

Vanoda kugara mukati mezvivakwa, kunyanya zvekurima, munogara zvipembenene zvakawanda, izvo zvinoumba chikafu chazvo.
Vanoda nzvimbo dzakati sandara, kunyangwe dzichiwanikwawo mumakomo, pakakwirira kusvika 1000 m pamusoro pegungwa. minda, zviri nani iine dziva riri pedyo.
4
Ishiri diki, nhete ine muviri wakareba 17 kusvika 19 cm.
Mapapiro anobva pa32 kusvika ku34.5 cm, uremu hunobva pa16 kusvika ku22 g. Vakadzi nevarume vakanyanya kufanana, vanogona kusiyaniswa nenyaya yokuti rectangles yevakadzi ipfupi zvishoma.
Saka, mhembwe dzakakura kudarika dzimwe dzadzo.
5
Ruvara rwepamusoro isimbi yeblue ine dumbu rakacheneruka. Musoro une ngura-tsvuku huma nehuro, yakaparadzaniswa nedumbu netambo yeblue-steel.
Muromo nemakumbo eshiri idzi zvitema uye zvinoonekwa nemakona akarebesa akarongwa muchimiro cheU.
6
Kudya kwezvimedza kunosanganisira zvipembenene, izvo zvavanobata nounyanzvi panguva yekubhururuka.
Hwaro hwekudya kwayo hunosanganisira hymenoptera, zvipembenene uye nhunzi. Kakawanda, vachitsvaka zvokudya, vanoenda kunzvimbo dzine unyoro nemitumbi yemvura, uko nhamba yezvipembenene izvi yakakura.
Kuti udzidze zvakawanda…
7
Varume vanoimba kakawanda kupfuura vakadzi.
Vanoita izvi kudzivirira ndima yavo kana kuti kutsvaka wokuroorana naye pakati paApril naAugust. Kuimba kwehadzi kupfupi uye kunoitika chete pakutanga kwemwaka wekubereka.
8
Idzi ishiri dzinotama; panguva yekuberekesa dzinobhururuka dzichienda kuchamhembe, dzinotakura chinhambwe chemakiromita anosvika zviuru gumi.
Kudzoserwa kunotanga kutanga kwaKurume uye dzimwe nguva kunogona kupera zvakashata. Kana dzikadzokera kwadzinoberekera munguva yechando, dzinogona kufa nekuda kwekushaikwa kwetumbuyu hwadzinodya.
9
Nguva yekuberekesa yezvipembenene izvi inotanga muna Chivabvu uye inopera kusvika muna Chikunguru.
Vanoda zvivakwa senzvimbo dzekugara, asi, kusiyana nemhembwe, vanovaka matendere mukati. Vanowanzo gadzira vana vaviri pagore.
10
Matendere anovakwa kubva kuvhu nevhu, akasanganiswa uye akaturikidzana.
Sezvinoita marina epamba, vanoavaka pasi penzvimbo yakati sandara, sedenga remba kana kuti maeves. Dendere racho rinenge rakapfava rinenge riripo seuswa, vhudzi, minhenga kana makushe. Sezvinoita mhuru dzemba, dzinogona kuvaka matendere mumapoka.
11
Kusiyana nenyenganyenga, musuwo wedendere renyenganyenga une buri rakati kurei.
Izvi zvinoita kuti zvive nyore kune vashanyi vasina kukokwa kuti vasvike mudendere, ndosaka mhembwe dziri idzo chete mhando dzeEuropean kumedza yakawira munjodzi yecuckoo parasitism.
12
Dzinoroorana kweupenyu hwose uye, kana dzangoroorana, dzinotanga kuvaka dendere.
Zvisinei, izvi hazvidzitadzisi kuberekesana nevamwe vanhu verudzi rwavo. Naizvozvo, vanogona kutorwa sevanogamists uye vanobereka barika.
13
Mhururu dzechirume dzinogara zvakanyanya uye dzinodzivirira dendere zvine hukasha. Vanoidzivirira zvakasimba kunyange kumatsi, idzo dzavanosvika kure kure mukuedza kudzidzinga.
Mhodzi dzemuEurope dzechirume dzinongodzivirirwa chete nedendere rekudzivirira, nepo vanhu vekuNorth America vachipedza imwe 25% yenguva yavo vachidyara mazai.
14
Muchikwata, hadzi inogona kukandira mazai maviri kusvika manomwe.
Mazai ekumedza machena ane ngura, akareba 20 x 14 mm uye anorema 2 g. Manhiyo anochechenya mushure memazuva 14 - 19 uye anobva mudendere mushure memamwe mazuva 18 - 23. Pashure pokunge abva mudendere, anodya kuvabereki vavo kwenguva inenge svondo.
15
Zvinoitika kuti mhuka dzechidiki kubva kumwana wekutanga dzinobatsira vabereki vavo kudyisa hama nehanzvadzi kubva kumwana wechipiri.
16
Ivhareji yehupenyu hwemhere haipfuuri makore mashanu.
Zvisinei, pane vanhu vakararama kusvika gumi nerimwe, kana kunyange makore gumi nemashanu.
17
Zvinoitika kuti mhodzi dzakapindirana nemhere.
Pakati pevatambi vese, iyi ndeimwe yeakajairika interspecific michinjikwa. KuNorth America neCaribbean dzakaberekesanawo nenyenganyenga mumapako nemhembwe dzine mitsipa mitsvuku.
18
Kazhinji kazhinji vanowira shiri dzinodya nyama, asi kubhururuka kwavo kusingawanzo kuponesa hupenyu hwavo.
MuIndia uye paIndochina peninsula, ivo vanovhimwawo zvinobudirira nemaremwaremwa ane mapapiro makuru.
19
Huwandu hwezvimedza pasi rose hunofungidzirwa kuva pakati pe290 ne487 miriyoni.
Huwandu hwenyunyu muPoland hunofungidzirwa kuva pakati pe3,5 ne4,5 miriyoni yeshiri dzakura.
20
Munyika dzeAfrica, shiri idzi dzinovhimwa nekuda kwekubika.
Ichi ndicho chimwe chezvikonzero zvekudzikira kwenhamba dzavo.
21
Haisi mhuka iri mungozi, asi yakanyatsochengetedzwa muPoland.
Sangano reInternational Union for Conservation of Nature rinoronga nyenganyenga serudzi rusinganyanyi kunetseka.
