Aquests dies estem d’enhorabona. Ens ha visitat un ocell molt bonic: la cotxa blava<\/strong> (Luscinia svecica<\/em>)<\/mark>. \u00c9s possiblement un dels ocells m\u00e9s curiosos que tenim, gr\u00e0cies als colors intensos en blau i vermell de la seva gola i pit. A Catalunya esdev\u00e9 un migrador com\u00fa tant a les zones humides del litoral com de l’interior, i \u00e9s un hivernant m\u00e9s esc\u00e0s. Potser heu sentit el seu cant<\/a><\/mark> i no ho sab\u00edeu.<\/p>\n\n\n\n

Es tracta un ocellet rabassut, cua llarga i bec fi, amb un plomatge en qu\u00e8 destaca la seva pitera tacada de blau, que en els mascles adults queda perfilada per una fina franja negra, envoltada al seu torn per una banda taronja m\u00e9s ampla. A m\u00e9s, els mascles posseeixen unes bigoteres tenyides de blau, que en algunes subesp\u00e8cies es fonen amb la gola, igualment blavosa. Depenent tamb\u00e9 de la subesp\u00e8cie, el pitet blau est\u00e0 adornat amb una taca, a manera de medalla, que pot ser blanca o taronja (dibuix 1<\/a><\/mark>).<\/p>\n\n\n\n

La coloraci\u00f3 de les femelles resulta menys cridanera. Solen lluir poc blau al pit, sovint tenen la gola de color blanc crema, i la banda taronja del pit est\u00e0 desdibuixada (dibuix 2<\/a><\/mark>). Tot i aix\u00f2, les femelles de m\u00e9s edat poden presentar una coloraci\u00f3 similar als mascles. Ambd\u00f3s sexes posseeixen una distintiva l\u00ednia blanca sobre l’ull i exhibeixen un dors marr\u00f3-grisenc. La cua, ataronjada fins a la seva meitat, est\u00e0 acolorida de negre o marr\u00f3 molt fosc a la part exterior. <\/p>\n\n\n\n

Aqu\u00ed us deixem unes fotos recents realitzades pel fot\u00f2graf local Guillermo L. Schmidt<\/em>, al qual volem agrair la seva col\u00b7laboraci\u00f3. Si voleu provar d’observar-la, no us adormiu, ja que segons els experts, d’aqu\u00ed a ben poc ja no ens acompanyar\u00e0 a la Reserva Natural de Sebes. Us animeu?<\/strong><\/p>\n\n\n\n
