Amplified fragment length polymorphism analysis identifies hybrids between two subspecies of warblers. By assuming a background level of heterozygote individuals (HH) of 1.5% in allopatric trochilus and acredula populations (Table 2), we observed that HH individuals were significantly over-represented in Italy (Binomial Probability Test, p-value = 0.00023). All authors discussed the outcome of the results and provided comments on the draft. First, if hybrids tend, as predicted, to winter in Central Africa, this region is not represented among our available samples. Juvenile Knot on Kilnsea wetlands. 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. We first tested the genotype assays on DNA from both blood and feathers for a limited number of samples (n = 8) with duplicates, to examine the consistency and success rate of this strategy. Bird Id provides easy access to an extensive database of information on world birds and enables you to quickly identify birds, view detailed bird information and record your sightings. The base of feather samples (~ 5 mm of either tail feathers or innermost primary flight feathers) were cut into two strips to expose the inner structure, and added to tubes with 100 μl lysis buffer and 1.5 proteinase K and incubated at 56 °C for 3 h with regular shaking every hour. Bensch S, Andersson T, Åkesson S. Morphological and molecular variation across a migratory divide in willow warblers, Phylloscopus trochilus. The willow warbler is often mistaken for a chiffchaff, however, to tell whether the bird in your garden is a chiffchaff or a willow warbler, listen out for their distinct song! J Avian Biol. The excess of hybrids in Italy, suggests that they employ an intermediate route relative to the parental populations. 2001;10(9):2263–73. Few studies have tested this hypothesis in wild birds, and only in hybrids that have completed the migration back to the breeding grounds. During autumn migration in southern Europe, juvenile trochilus and acredula dominated in western (Portugal) and eastern Europe (Bulgaria), respectively, also in line with the well documented autumn migration directions of these subspecies [19, 22]. Oikos. Juveniles sampled in Portugal, Italy and Bulgaria clearly had different genotype compositions (Fig. 1). Examples of sample dual scatterplot of SNP genotyping results. bird. In contrast to experienced adult migrants, as solitary migrants, juveniles have to rely on their endogenous navigation system and the inherited direction or “goal” as guidance [34]. The call is a quiet repeated “tik” and the song a short dry trill. Liedvogel M, Larson KW, Lundberg M, Gursoy A, Wassenaar LI, Hobson KA, et al. Examples of the results are illustrated in Figure S2a (Bio-Rad CFX) and Figure S2b (Mx3005P). The Tits both have black bibs. 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].

We found that the single SNPs genotyped by qPCR were generally good at predicting the haplotypes assigned by the SNP array [28] (Table S3). The sample collection in Bulgaria was supported by grant from the Bulgarian Science Fund (DO02–277) to MI. 2012;279(1747):4582–9. In: Birds of two worlds: the ecology and evolution of migration; 2005. p. 27–40. Among the winter samples, we did not find any individual with a presumed origin from the hybrid zones (HH, SN or NS individuals). Google Scholar. Mov Ecol.

Rabøl J. One-direction orientation versus goal area navigation in migratory birds. songbird. Based on these calculations, we conclude that genotypes HH, SN and NS are extremely unlikely to originate from populations of pure trochilus or acredula. Springer Nature. Figure S3. Thomas Carlyle.

For each SNP, a 400 bp sequence with the target SNP in the middle was submitted to the server, in which all other irrelevant SNPs were marked as “N”. These bird identification guides provide information about over 190 of the most common British birds including garden birds, birds of prey, shorebirds and waterfowl. Bowlin MS, Henningsson P, Muijres FT, Vleugels RH, Liechti F, Hedenström A. In species with known population genetic structure, such as the willow warbler, the here used qPCR-based SNP genotyping makes it possible to reveal details of the first-year migration that will be difficult to obtain with other methods. : O. OlaB Well-known member. 1999;53(6):1925–35. Juvenile willow warblers have pale yellow superciliums and pale yellow on the upperparts, their chins are paler and the breast is pale buff. This rough estimate would scale to a reduction of hybrid survival from e.g. 0 1 0. 0 0 0. The subspecies acredula breeds in eastern Europe and northern Scandinavia and migrates through eastern Europe to wintering grounds in eastern and southern Africa. Campbell NR, Narum SR. Quantitative PCR assessment of microsatellite and SNP genotyping with variable quality DNA extracts. Biol Lett. Link Posted 18/03/2020 - 22:06 Good capture and a nice composition too . We used the above mentioned pure trochilus and acredula breeding samples from Scandinavia to evaluate how well the single SNPs can be used to predict the haplotype assignment on the regions of chromosomes 1 and 5, as well as their fixation level, i.e. Juvenile Willow Warbler in Alexandra Park, Dennistoun, Glasgow. The trochilus and acredula populations meet in a well-defined contact zone in central Scandinavia and in a broader more diffuse zone in Poland [22] (Fig. 1987;64(4):137–43. Proc Biol Sci. Found in dry savanna habitats, mostly in acacia trees. Feather samples from Portugal were collected under the licenses 86/2009, 122/2009/CAPT and 92/2010 issued by CEMPA/ICNF. Juvenile willow warbler perches on a fence Dimensions 5472 x 3648 pixels Simon Wills 86 photos. This is a green- and yellow-tinged bird, with a thin, long supercilium, a long wing and yellowish legs. The motus wildlife tracking system: a collaborative research network to enhance the understanding of wildlife movement. Our qPCR SNP genotyping method is efficient for processing large sample sizes, and will therefore be useful in migration research of species with known population genetic structure. Table S2.

Blood samples from Bulgaria were collected under permission 213/26.6.2009 issued by Ministry of Environment and Water of Bulgaria. To identify which of the genes in the differentiated chromosome regions that may determine migratory direction, will require data on the migratory routes for a larger sample of hybrids, F2’s and back-crossed individuals, as well as samples from a wider geographical range. The problem with this feature is that Willow Warbler leg colour can sometimes vary and birds with dark legs have been seen but this is the rare exception to the rule. Juvenile willow warblers are often much more yellow than adults. Sokolovskis K, Bianco G, Willemoes M, Solovyeva D, Bensch S, Åkesson S.

The DNA sample collection that have been used for SNP genotyping in this study, including the sample sizes, sample sources, sampling year and origin. Because there is a substantial proportion of breeding willow warblers of hybrid origin in the migratory divides [28], i.e. Mol Ecol. Passeriformes Order – Phylloscopidae Family. - SCOTLAND: The Big Picture Based on the same assumption, the HH individuals were not significantly over-represented in Portugal (Binomial Probability Test, p-value = 0.07) or in Bulgaria (Binomial Probability Test, p-value = 0.62). John Hewitt. Among other methodologies for studying migration, GPS transmitters are hitherto too big for most of the songbirds [14]. No evidence for assortative mating within a willow warbler migratory divide. Comparison between SNP genotype results from this study and the whole-block genotype results from Lundberg et al.
