释义 |
The term Western Palearctic black-and-white flycatchers is used to refer to a group of similar-looking birds in the genus Ficedula:
European pied and collared flycatchers hybridise to a limited extent where their ranges meet; the hybrids have reduced fitness and usually do not survive their first winter (Parkin 2003). Female hybrids are usually sterile (Gelter et al. 1992; see also Haldane's Rule). All species leave their breeding grounds to winter in Sub-Saharan Africa. References
