Popula\u021bie<\/strong>
\nPopula\u021bia european\u0103 este relativ mic\u0103 \u0219i este cuprins\u0103 \u00eentre 35 000 \u2013 55 000 perechi. Un declin moderat s-a manifestat \u00een perioada anilor 1970 \u2013 1990, ce a continuat \u0219i \u00een perioada 1990 \u2013 2000. Pe ansamblu popula\u021bia manifest\u0103 un declin moderat. Cele mai mari efective sunt \u00een Rusia, Italia \u0219i Fran\u021ba.<\/p>\n


\nSose\u0219te din cartierele de iernare, la sf\u00e2r\u0219itul lunii aprilie. Femela depune \u00een mod obi\u0219nuit 2 \u2013 3 ou\u0103, \u00een a dou\u0103 parte a lunii mai \u0219i \u00een prima parte a lunii iunie, cu o dimensiune medie de 31,5 x 23,1 mm.

Amenin\u021b\u0103ri \u0219i m\u0103suri de conservare<\/strong>
\nDeranjul determinat de activit\u0103\u021bile umane, ce duce la pierderea locurilor de cuib\u0103rit, prin urbanizarea teritoriilor caracteristice speciei, al\u0103turi de inundarea cuiburilor reprezint\u0103 pericolele principale ce afecteaz\u0103 specia. Reducerea deranjului produs de activit\u0103\u021bile umane \u0219i construirea de platforme artificiale, pentru asigurarea de locuri sigure pentru cuib\u0103rit, sunt prioritare.<\/p>\n
