Fluviul Dun\u0103rea, dup\u0103 un parcurs de 2.850 km prin Europa, \u00ee\u0219i \u00eencheie drumul prin v\u0103rsarea apelor sale \u00een Marea Neagr\u0103, prin cea mai bine conservat\u0103 delt\u0103 \u0219i cea de-a doua ca m\u0103rime din Europa \u2013 Delta Dun\u0103rii. Ceea ce o face deosebit\u0103 este abunden\u021ba de specii de flor\u0103 \u0219i faun\u0103 care pot fi \u00eent\u00e2lnite tot timpul anului, dar \u0219i numeroasele tipuri de habitate naturale specifice zonelor umede costiere, care ofer\u0103 vizitatorilor peisaje deosebite.<\/p>\n

Valoarea universal\u0103 a Deltei Dun\u0103rii \u0219i a zonelor adiacente a fost recunoscut\u0103 prin declararea lor ca rezerva\u021bie a biosferei \u0219i includerea \u00een re\u021beaua interna\u021bional\u0103 a rezerva\u021biilor biosferei (1990), \u00een cadrul Programului \u201eOMUL \u0218I BIOSFERA\u201d (MAB), lansat de UNESCO. Caracterul universal al Deltei Dun\u0103rii a fost recunoscut \u0219i prin includerea acesteia \u00een Lista Patrimoniului Mondial Cultural \u0219i Natural, \u00een decembrie 1991, situl nr. 588\/1991. Valoarea patrimoniului natural \u0219i eficien\u021ba planului de management ecologic aplicat \u00een teritoriul Rezerva\u021biei Biosferei Delta Dun\u0103rii au fost recunoscute prin acordarea \u00een anul 2000 a Diplomei Europei pentru Arii Protejate (re\u00eennoit\u0103 succesiv \u00een 2005 \u0219i 2010).<\/p>\n

Printre cele peste 300 de specii de p\u0103s\u0103ri care viziteaz\u0103 sau populeaz\u0103 permanent delta \u00eent\u00e2lnim \u0219i Leb\u0103da de var\u0103<\/strong> – Cygnus olor<\/em> (Gmelin, 1789), ilustrat\u0103 \u00een diverse ipostaze, pe cele patru timbre ale emisiunii, cu valorile nominale de 3,30 lei, 5 lei, 8,50 lei <\/em><\/strong>\u0219i 10,50 lei<\/em><\/strong>. Specia este denumit\u0103 popular leb\u0103da cucuiat\u0103 <\/em>\u0219i are un areal de r\u0103sp\u00e2ndire sud-palearctic fragmentat, constituit din c\u00e2teva segmente majore: Irlanda \u0219i Marea Britanie, Europa central-vestic\u0103, zona M\u0103rii Baltice, zona M\u0103rii Negre, zona M\u0103rii Caspice, Asia central-vestic\u0103, China \u0219i \u021binutul Ussuri (Rusia \u0219i China), av\u00e2nd \u00een cadrul acestor teritorii o distribu\u021bie punctiform\u0103 cu nuclee restr\u00e2nse de cuib\u0103rit.<\/p>\n

\u00cen Rom\u00e2nia este r\u0103sp\u00e2ndit\u0103 \u00een Delta Dun\u0103rii \u0219i complexul lagunar Razelm-Sinoe, unde se afl\u0103 majoritatea popula\u021biei cuib\u0103ritoare din \u021bara noastr\u0103, precum \u0219i alte c\u00e2teva zone umede din restul Dobrogei, estul Munteniei \u0219i zone din Moldova. Ca habitat prefer\u0103 lacurile \u00eentinse, eutrofe, cu stuf\u0103ri\u0219 abundent \u0219i alte plante palustre, dar care au \u00een acela\u0219i timp \u0219i suprafe\u021be \u00eentinse de ap\u0103 liber\u0103.<\/p>\n

Este o specie sedentar-migratoare \u0219i oaspete de iarn\u0103. \u00cen iernile bl\u00e2nde, probabil c\u0103 majoritatea exemplarelor din delt\u0103 sunt sedentare, \u00een timp ce \u00een iernile aspre, ele se deplaseaz\u0103 spre sud, \u00eencep\u00e2nd cu luna noiembrie, locul lor fiind luat de exemplare ce provin din \u021binuturi situate la nord de Marea Neagr\u0103.<\/p>\n

Leb\u0103da cucuiat\u0103 sau leb\u0103da de var\u0103 are o greutate 9-13 kg, iar masculul este mai mare dec\u00e2t femela. Se hr\u0103ne\u0219te cu plante acvatice \u0219i \u00eentr-un procent mic cu nevertebrate acvatice. Alege locul de cuib\u0103rit \u00een martie-aprilie. Cuibul mare este construit din vegeta\u021bie palustr\u0103 (papur\u0103, trestie), noroi \u0219i este c\u0103ptu\u0219it cu fulgi. O pereche poate s\u0103 cloceasc\u0103 5 -12 ou\u0103, dar frecvent ponta con\u021bine numai 5 – 7 ou\u0103 cenu\u0219ii sau verde-pal. C\u00e2nd femela cloce\u0219te masculul o p\u0103ze\u0219te. Incuba\u021bia dureaz\u0103 36 – 38 de zile. Puii sunt acoperi\u021bi cu puf cenu\u0219iu \u0219i r\u0103m\u00e2n \u00een cuib o singur\u0103 zi. \u00cen timp ce femela cloce\u0219te \u00eenc\u0103, masculul \u00eengrije\u0219te puii ecloza\u021bi. Dup\u0103 v\u00e2rsta de 60 de zile puii pot zbura. Sunt p\u0103s\u0103ri teritoriale \u0219i agresive. \u00cen captivitate pot tr\u0103i 30-40 de ani. Conform datelor din literatura rom\u00e2neasc\u0103, \u00een Delta Dun\u0103rii \u0219i complexul lagunar Razelm-Sinoe cuib\u0103resc \u00eentre 800 \u0219i 1000 de perechi, iar \u00een restul \u021b\u0103rii alte c\u00e2teva zeci de perechi.<\/p>\n

Factorii limitativi sunt reprezenta\u021bi \u00een principal de presiunea antropic\u0103 exercitat\u0103 prin braconaj. \u00cen Delta Dun\u0103rii, \u00een trecut au fost semnalate cazuri \u00een care localnicii culegeau ou\u0103le proaspete pentru a le consuma, precum \u0219i cazuri de lebede care au fost prinse accidental \u00een capcane instalate pentru prinderea bizamilor. Un alt factor de risc este \u00eenghi\u021birea accidental\u0103 de c\u0103tre lebede a c\u00e2rligelor \u0219i greut\u0103\u021bilor de plumb folosite de pescari. \u00cen Rom\u00e2nia este o specie protejat\u0103.<\/p>\n
