Common cuckoo of two years. More than 100 host species have been recorded: meadow pipit, dunnock and Eurasian reed warbler are the most common hosts in northern Europe; garden warbler, meadow pipit, pied wagtail and European robin in central Europe; brambling and common redstart in Finland; and great reed warbler in Hungary. Female common cuckoos are divided into gentes – groups of females favouring a particular host species' nest and laying eggs that match those of that species in color and pattern. Evidence from mitochondrial DNA analyses suggest that each gene may have multiple independent origins due to parasitism of specific hosts
Common redpoll a further thirteen days. Common redpoll The common redpoll ("Acanthis flammea") is a species of bird in the finch family. It breeds somewhat further south than the Arctic redpoll, also in habitats with thickets or shrubs. The common redpoll was listed in 1758 by Linnaeus in the 10th edition of his "Systema Naturae" under the binomial name "Fringilla flammea". The current genus name "Acanthis" is from the Ancient Greek "akanthis", a name for a small now-unidentifiable bird, and "flammea" is the Latin for "flame-coloured". The common redpoll was previously placed in the genus "Carduelis". Molecular phylogenetic studies showed that the
