Résumé :	Tengmalm's Owl usually nests once per breeding season. When food conditions are exceptionally good, a female may mate with another male and start nesting again while the chicks of her first brood are still fledglings. If the number of small mammals suddenly soars up at a time of extreme shortage of female Tengmalm's Owls in that area, a female may even nest three times in succession in one breeding season. One example of this phenomenon was encountered in Northern Bavaria in the district of Hof/Saale in the breeding season of 2007 and one female was witnessed nesting successfully on the gravel plain of Munich three times in succession in the breeding season of 2012.
