USTUHONBANDI VA MUSHAKI PARRANDAHO

Sokhti ustukhonbandii parrandaho az digar muhradoron farq mekunad. Masalan, muhrai parrandaho ba daroziash sokhti zinshaklro megirad. Muhrai parrandaho az qismi gardan, sina, chorband, dum iborat buda, adadi onho gunogun ast. Az jumla muhramkhoi gardanii parrandamho to ba 25 adad rasida, yakjoya sokhti zinshaklro giriftaast. Masalan, dar kabutar 14, dar parrandai khurdi tropiki, ki yak gr. vazn dorad — 9, dar parrandahoi gardandaroz (laklak, qu, turna, flamingo) to 25 muhrai gardani hast. Az in sabab parrandaho dar yak jo istoda, sarashonro ba 360 daraja davr zanonda metavonand.

kabutar

Qafasi sinai parrandagon asosan az 4 muhrai bo ham chaspida iborat buda, baraksi muhrahoi gardani beharakat meboshand.

Muhrahoi chorband dar hamai parrandaho yak miqdor nest. Masalan, dar chorbandi kabutar 14 muhra yakjoya payvast shudaand.

Muhrahoi dumi ba hisobi miyona 7-to buda, okhirash ba gadudi dumgozagi mubaddal shudaast.

Kosai sari parrandaho az jihati sokhtash ba kosai sari khazandaho nazdik ast. Lekin kosai sari parrandaho sabuk buda, qismho ba ham barjasta chaspidaand.

Dar asosi nuli parrandaho uzvi rastaki bini hast, ki ba daruni jogi boloy roh dorad.

Qismi kitfi parrandaho az ustukhoni belcha, kalitak iborat ast. Gayr az in ustukhonhoi qismi qafasi sina ba poyhoi pesh payvast shudaand.

Agar poyhoi peshro, ki bol yo ki qanot meguyand, az paru pat toza kuned, mebined, ki az ustukhoni kitf, orinj, soq va panjaho iborat ast.

Azbaski parrandaho tukhmzoy meboshand, tukhmi kalon-kalon dorand. qismi ustukhoni kos vase meshavad. Ustukhonn kos bo poyhoi aqib aloqamand ast. Skeleti poy az ustukhoni ron, soq, panjaho iborat meboshad. Baze parrandaho na bo panchahoyashon.

Balki bo pikh ba zamin takya mekunand, ki yak vaqtho on panjai panjumin bud va holo reduksiya shuda, izi on boqi mondaast, ki vayro pikh menomand.

Qismi az hama sermushaki parranda qafasi sina buda, tamomi harakati bolro ba tartib medarorad. Mushakhoi gardan ham nagz inkishof yofta, ba harakati cap yori merasonand. Mushaki poyhoi parrandagoni dashtiyu biyoboni (shuturmurg, dugdog) khele boquvvatand, Dar hamai parrandagoni darakhtgard mushakhoi qatkunandai panjaho chunon inkishof yoftaand, ki hatto shabona shokhasro doshta, orom khob meravadu nameaftad. Gayr az in, mushaki poyhoi parrandahoi oby ham nagz inkishof yoftaast.

Vazni khosi parranda ham misli samolyot az qafo vaznin buda, baroi bolo baromadan va poyon furomadan mushakhoi makhsusi qafasi sina kor mekunand. Quvvai teladihanda on vaqt ba vujud meoyad, ki bolhoi parranda tez-tez poyon meshavad. Parranda ham misli samolyot az joyi istodaash surat girifta, medavad yo az boloi balandie khudro khavo doda, bo jahish parvoz mekunad.

Surati parvozi parrandagon har khel ast. Masalan, kabutar dar yak soat az 50 to 90 km parvoz mekunad.
