Crestetul cenu\u0219iu este o specie caracteristic\u0103 zonelor umede, cu mult\u0103 vegeta\u021bie \u0219i \u00een special stuf. Lungimea corpului este de 17 \u2013 19 cm. Anvergur\u0103 aripilor este cuprins\u0103 \u00eentre 34 \u2013 40 cm. Adul\u021bii au \u00eenf\u0103\u021bi\u0219are diferit\u0103. Masculul are corpul albastru \u2013 gri, iar femela gri \u2013 alburiu. \u00ce\u0219i face sim\u021bit\u0103 prezen\u021ba prin sunete care se aud de la distan\u021b\u0103. Se hr\u0103ne\u0219te cu insecte, larve, molu\u0219te, semin\u021be ale plantelor acvatice.<\/p>\n

Localizare \u0219i comportament<\/strong>
\nEste o specie prezen\u021ba pe cea mai mare parte a continentului european, teritorial\u0103, monogam\u0103, la care perechea se p\u0103streaz\u0103 pe durata unui sezon de cuib\u0103rit. Duce o via\u021b\u0103 retras\u0103 \u0219i este greu de observat, mai ales c\u0103 este activ\u0103 sear\u0103 \u0219i noaptea. Cuibul este construit de c\u0103tre ambii parteneri, din frunze de stuf \u0219i fire de plante, \u00een locuri greu accesibile \u0219i are form\u0103 de sfera. \u00cen serile de prim\u0103var\u0103, se aud chem\u0103rile repezite ale masculului. Ierneaz\u0103 \u00een Africa \u0219i Peninsula Arabiei.<\/p>\n

Popula\u021bie\"\"<\/strong>
\nPopula\u021bia european\u0103 a speciei este relativ mic\u0103 \u0219i cuprins\u0103 \u00eentre 61.000 \u2013 140.000 perechi. A crescut semnificativ \u00eentre 1970 \u2013 1990. De\u0219i s-a men\u021binut stabil\u0103 \u00een cea mai mare parte a teritoriului european, \u00een perioada 1990 \u2013 2000 a \u00eenregistrat un declin \u00een Ucraina ceea ce a determinat o descre\u0219tere a popula\u021biei pe ansamblu. Cele mai mari efective sunt \u00een Ucraina, Austria \u0219i Rusia.<\/p>\n

\u00cemperechere <\/strong>
\nSose\u0219te din cartierele de iernare la sf\u00e2r\u0219itul lunii martie \u0219i \u00eenceput de aprilie.\u00a0 Femela depune de obicei 7 \u2013 9 ou\u0103 la sf\u00e2r\u0219itul lunii aprilie \u0219i \u00eenceput de mai, cu o dimensiune medie de 30,1 x 21,7 mm. Incubatia dureaz\u0103 \u00een medie 19 \u2013 21 de zile, \u0219i este asigurat\u0103 de ambii parteneri. Puii ies din ou cu un puf lung \u0219i negru iar ciocul e alb – g\u0103lbui. Puii \u00ee\u0219i urmeaz\u0103 p\u0103rin\u021bii, care le asigura hran\u0103 \u0219i devin zbur\u0103tori la 25 \u2013 29 de zile.\"\"<\/p>\n

Amenin\u021b\u0103ri \u0219i m\u0103suri de conservare<\/strong>
\nDistrugerea \u0219i degradarea zonelor umede reprezint\u0103 principalele pericole ce afecteaz\u0103 specia. Prin proiectul Wings Over Wetlands se urm\u0103re\u0219te refacerea unor zone umede situate pe traseul de migra\u021bie al speciei. Conven\u021bia p\u0103s\u0103rilor migratoare (Conservation of African-Eurasian Migratory Waterbirds) include \u0219i aceast\u0103 specie.<\/p>\n
