Extra-pair paternity in Short-toed and Lesser Short-toed Larks Calandrella brachydactyla and C. rufescens
Capsule DNA fingerprinting suggests that extra-pair paternity may be frequent among larks. Extra-pair paternity is widespread in passerines, even in species traditionally considered to be strictly monogamous (Birkhead & Møller 1998), though it remains unreported or not quantified in some taxa. L...

| Summary: | Capsule DNA fingerprinting suggests that extra-pair paternity may be frequent among larks. Extra-pair paternity is widespread in passerines, even in species traditionally considered to be strictly monogamous (Birkhead & Møller 1998), though it remains unreported or not quantified in some taxa. Larks (Alaudidae), a ‘primitive ’ passerine family with over 100 species, are considered monogamous (Dean et al. 1992, Cramp 1998) as most are territorial and many show a semi-colonial nesting behaviour (i.e. the species of the genera Eremopterix and Chersophilus, and some species of Melanocorhypha, Calandrella, Eremophila and Spyzocorys; De Juana et al. in press). A few species present a non-aggregated spatial distribution of nests: |
