R\u00e2ndunica<\/span> – Hirundo rustica – <\/em><\/strong>este foarte r\u0103sp\u00e2ndit\u0103 \u00een toat\u0103 Europa pe perioada verii. Poate fi \u00eent\u00e2lnit\u0103 din delt\u0103 \u0219i p\u00e2n\u0103 \u00een v\u0103ile mun\u021bilor. R\u00e2ndunica este un zbur\u0103tor des\u0103v\u00e2r\u0219it, calitate care o folose\u0219te \u0219i pentru a-\u0219i procura hrana. Din acest motiv prefer\u0103 s\u0103 cuib\u0103reasc\u0103 \u00een apropierea zonelor deschise care \u00eei ofer\u0103 culoare largi pentru a zbura \u00een vederea dob\u00e2ndirii hranei. Zonele de cuib\u0103rit le alege \u00een func\u021bie de abunden\u021ba insectelor din arealul respectiv. Doar exemplarele din sudul Peninsulei Iberice nu migreaz\u0103. Exemplarele care tr\u0103iesc la noi \u00een \u021bar\u0103 plec\u0103 toamna devreme, \u00een stoluri mari, c\u0103tre Africa, de obicei \u00een zona subsaharian\u0103, dar pot ajunge p\u00e2n\u0103 \u00een sudul continentului.\"\"
\nR\u00e2ndunica este neagr\u0103 pe spate, aripi ,cap \u0219i pe g\u00e2t cu ceva reflexii albastre metalice. Pe frunte \u0219i sub cioc are o pat\u0103 c\u0103r\u0103mizie. Pe piept \u0219i pe burt\u0103 este de culoare alb-g\u0103lbuie. Are o siluet\u0103 foarte elegant\u0103, iar coada este terminat\u0103 cu dou\u0103 pene mai lungi \u0219i sub\u021biri – celebra \u201ccoad\u0103 de r\u00e2ndunic\u0103\u201d \u00een form\u0103 de \u201cV\u201d, iar ciocul este scurt \u0219i turtit, cu deschidere mare. R\u00e2ndunica poate ajunge la o lungime de 20 cm \u0219i o greutate de 25gr. Ea poate atinge o v\u00e2rst\u0103 de p\u00e2n\u0103 la 8 – 10 ani.<\/p>\n

Sunt foarte bune zbur\u0103toare, adev\u0103rate acrobate \u0219i sunt rar v\u0103zute pe p\u0103m\u00e2nt. Pot atinge viteze incredibile, de pana la 160 km\/h, schimb\u00e2ndu-\u0219i brusc direc\u021bia \u00een aer. Aceast\u0103 caracteristic\u0103 le ajut\u0103 mult pentru evitarea pr\u0103d\u0103torilor dar \u0219i pentru a se hr\u0103ni. Este bine cunoscut faptul c\u0103 r\u00e2ndunica se hr\u0103ne\u0219te cu insecte pe care le prinde direct din zbor. La fel bea \u0219i ap\u0103.
\nCuibul este construit de ambii parteneri, din p\u0103m\u00e2nt amestecat cu pietricele, p\u0103r \u0219i paie iar interiorul este c\u0103ptu\u0219it cu puf \u0219i p\u0103r de animale. Acest cuib este amplasat \u00een cele mai diverse locuri, mai ales sub stre\u0219inile caselor, dar \u0219i \u00een poduri, garaje, chiar \u00een interiorul caselor (atunci c\u00e2nd exist\u0103 o deschidere permanent\u0103 spre exterior). Un caz incredibil, dar adev\u0103rat, s-a petrecut atunci c\u00e2nd o r\u00e2ndunic\u0103 a picat \u00een zbor pe spatele unei pisici, smulg\u00e2ndu-i cu ciocul c\u00e2teva fire din blana moale, pentru a-\u0219i c\u0103ptu\u0219i cuibul! Construc\u021bia acestui ad\u0103post dureaz\u0103 cam o s\u0103pt\u0103m\u00e2n\u0103. Au fost \u00eent\u00e2lnite cuiburi de r\u00e2ndunic\u0103 \u00een cele mai ciudate locuri: \u00eentr-o cabin\u0103 de tractor abandonat, \u00een l\u0103mpi ag\u0103\u021bate \u00een tavanul grajdurilor… \u00een 1978, \u00een Fran\u021ba, s-a descoperit un cuib de r\u00e2ndunic\u0103 construit \u00een gura unui bidon de lapte, ag\u0103\u021bat de un cui, \u00eentr-un \u0219opron. \u00cen alt caz, r\u00e2ndunelele \u0219i-au construit cuibul sub strea\u0219ina unui vagon de tren, care parcurgea zilnic un traseu de 3 km! Dup\u0103 cum se vede, acestor p\u0103s\u0103ri nu le lipse\u0219te niciodat\u0103 inventivitatea. Femela depune p\u00e2n\u0103 la 6 ou\u0103 de culoare alb\u0103 cu pete brune. Ambii parteneri clocesc prin rota\u021bie, iar perioada de incuba\u021bie este de 15 zile. Puii de r\u00e2ndunic\u0103 sunt hr\u0103ni\u021bi de p\u0103rin\u021bi timp de 4 s\u0103pt\u0103m\u00e2ni. De obicei scot dou\u0103 serii de pui. S-a calculat c\u0103 pentru hr\u0103nirea tuturor puilor, o r\u00e2ndunic\u0103 ajunge s\u0103 fac\u0103 nu mai pu\u021bin de 400 de zboruri pe zi!<\/p>\n
