Abstract

The Little Bittern is one of the least studied heron species in its breeding range. The nominate, Palaearctic race Ixobrychus m. minutus has been generally assumed to be single-brooded only, yet detailed studies of its breeding biology and mating system are lacking. The present paper provides the first observational evidence of successful double-brooding in the nominate race of the Little Bittern and gives the first record of time-overlapping double-brooding in the species. Potential determinants of this breeding strategy as well as the frequency of its occurrence are discussed.
