Juvenile Yellow Warbler begging – Nikon D500, f7.1, 1/1000, ISO 400, -0.3 EV, Nikkor 500mm VR with 1.4x TC, natural light. However, the route across the central Mediterranean Sea is nonetheless a major migration route for some other species of songbirds, e.g. In the UK, warblers can be separated into several groups – leaf warblers (slender, greenish birds of woodland and scrub, with simple soft call notes), reed, bush and grasshopper warblers (browner birds that live in wet places) and the Old World warblers (generally more patterned birds of woods and bushy places with short, hard call notes). Juvenile or Adult in Autumn plumage The juvenile and adult in autumn plumage are very similar, the underside and eye stripe are much more primrose yellow than the adult in spring and summer plumage. Bright autumn birds can invoke thoughts of Wood Warbler. Proc R Soc Lond Ser B Biol Sci. The classic studies of experimentally cross-bred blackcaps from populations with SW and SE migration, respectively, used orientation cages to demonstrate that F1 hybrids exhibited an intermediate direction towards south [8]. Robert Plant - male Siskin; Terry Hanna - adult and juvenile Willow Warblers PubMed Central  Inheritance of migratory direction in a bird species: a cross-breeding experiment with SE-and SW-migrating blackcaps (Sylvia atricapilla). From the equation in Barton and Hewitt (1985) [33], and using estimates of dispersal distances (σ ≅ 80 km) and width of the hybrid zone (250 km) [22], we can calculate that the selection against hybrids is ~ 10% per generation. Does migration of hybrids contribute to post-zygotic isolation in flycatchers? Wilson’s Warblers dance around willow and alder thickets, often near water, to the rapid beat of their chattering song. - SCOTLAND: The Big Picture Dennis Hasselquist and Thomas Alerstam have joined the discussion of the project and provided valuable opinions. The “intermediate route” hypothesis has been investigated by various methods. Bensch S, Grahn M, Müller N, Gay L, Åkesson S. Genetic, morphological, and feather isotope variation of migratory willow warblers show gradual divergence in a ring. 1996;199(1):49–55. willow warbler. Ibis. Baggott GK. 2010;1(4):398–402. Named after 18th century zoologist, Francesco Cetti, the Cetti's warbler is a medium-sized warbler of willow scrub, marshes and nettlebeds. 2009;6(3):297–300. http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s40462-020-00209-7. Helbig AJ. The qPCRs for all the samples in the present study were run on 96-plates including both negative and two positive controls. We used the allele frequencies in the southern and northern Scandinavian willow warbler populations (Table 1) to estimate the expected occurrence rate of each genotype within these populations, under the assumption of Hardy-Weinberg equilibrium (Table 2). 2017;1(3):155–68.

Our study on juvenile willow warblers supports the hy-pothesis that hybrids tend to follow an intermediate route during autumn migration compared to the paren-tal populations. Autumn migration direction of juvenile willow warblers (Phylloscopus t. trochilus and P. t. acredula) and their hybrids assessed by qPCR SNP genotyping. Article  SONGS & CALLS. Common Whitethroat. This finding also supports the hypothesis that the divergent blocks on chromosome 1 and 5 in willow warblers [28] may contain genes encoding migration direction. 1 0 0. In line with this, Lundberg et al. SB initiated and supervised the project. The sample collection in Bulgaria was supported by grant from the Bulgarian Science Fund (DO02–277) to MI. These studies suggested that hybrids between two species of flycatchers and between Acrocephalus warblers occupied wintering areas, and presumably used migration routes, that were similar to one of the parental species rather than migrating intermediately. Rob. Table S5. (1) Samples from western Europe (Portugal) will be dominated by the “trochilus” genotype. Wilson’s Warblers dance around willow and alder thickets, often near water, to the rapid beat of their chattering song. PLoS One. Related content. Mouritsen H. Spatiotemporal orientation strategies of long-distance migrants. song. To do so, we developed an individual-based model (IBM) to simulate full drift and partial compensation migration of juvenile Willow Warblers (Phylloscopus trochilus) along the southwesterly (SW) European migration corridor to the Iberian coast. Helbig A. Mol Ecol Notes. SNP genotyping results from southern Europe in autumn (August–October). Anim Biotelem. Link Posted 18/03/2020 - 22:06 Good capture and a nice composition too . Chiffchaffs and willow warblers arriving in the UK are just two … We named the two on chromosome 1 “23” and “65”, and the two on chromosome 5 “285” and “412”, corresponding to the scaffolds on which they were located (Figure S1).
