“…Both male territorial song and call notes clearly differ (Thielcke & Linsenmair 1963; Salomon 1989; Salomon & Hemim 1992; Helbig et al . 1996), although some males utter a song containing elements of the typical songs of both taxa (mixed singers) (Thielcke & Linsenmair 1963). In areas where both occur, collybita and brehmii males are interspecifically territorial.…”

Amplified fragment length polymorphism analysis identifies hybrids between two subspecies of warblers

In the western Pyrenees (Southwest France and Northwest Spain), a narrow hybrid zone exists between the common chiffchaff Phylloscopus (collybita) collybita and the Iberian chiffchaff Phylloscopus (c.) brehmii. In this zone, which is approximately 20 km wide, mixed matings and individuals singing the songs of both taxa occur at substantial frequencies (24 and 8.6%, respectively), suggesting frequent hybridization. Previous studies have shown very weak mitochondrial gene flow (Nm = 0.065), whereas four microsatellites suggested much higher nuclear gene flow (Nm = 4.9). In this study we used the amplified fragment length polymorphism (AFLP) method in order to identify hybrids and early backcrosses. We typed 91 birds from both allopatric and sympatric areas for 12 informative AFLP markers (of > 141 polymorphic fragments), obtained by screening 13 AFLP primer combinations. These individuals were previously typed for song (brehmii, collybita or mixed singers), mitochondrial DNA (mtDNA) haplotype and allelic genotypes at four microsatellite loci. Assignment tests demonstrated that in the zone of sympatry, a substantial number of intermediate genotypes existed among the birds previously believed to be pure collybita and brehmii, based on song and mtDNA haplotype. The majority of the mixed singers had intermediate genotypes. Our data suggest that the fraction of the adult population having a hybrid origin (hybrids or backcrosses) is in the order of 10%. With such a frequency of genetic hybrids, there would have been much more mtDNA introgression than observed, had female hybrids been perfectly fertile/viable. This result is consistent with male-biased gene flow and Haldane's rule.

“…Firstly, in Spain the Chiffchaff sings a song that must, from several aspects, be considered as being intermediate between the songs of Chiffchaff and the Willow Warbler songs in other part of Europe (Thielcke and Linsenmair 1963).

“…Sex was determined by the presence of incubation patches in females or of specific behaviour patterns (Salomon 1989a); 10 of these birds were mixed singers, i.e. birds emitting mixed songs, with structures pertaining to both taxa (Thielcke & Linsenmair 1963, Salomon 1987) (cf. Table 1).…”

“…The two taxa coexist along a narrow secondary contact belt located in the foothills of the western Pyrenees. They differ considerably in their songs (Lynes 1914, Ingram 1926, Ticehurst & Whistler 1928, Mayaud 1943, Niethammer 1963, Thielcke & Linsenmair 1963, Becker et al . 1980, Salomon 1987 and calls (Bernis 1945, Salomon 1987) but their morphometric diagnosis was difficult to ascertain until recently .…”

We carried out a Principal Component Analysis on 196 Iberian and Common Chiffchaffs of both sexes (live and collection specimens), characterized by seven variables derived from wing, tarsus and bill measures. This method, complemented by colour comparison of the taxa, led us to the following conclusions. (1) Phyllopneuste brehmii, Homeyer, 1871, is a junior synonym of Sylvia collybita, Vieillot, 1817. The correct name for the Iberian Chiffchaff is Phylloscopus ibericus (Ticehurst 1937). (2) P. ibericus is itself represented by two subspecies: the southern form P. i. ibericus (Ticehurst 1937), and the northern form, for which we propose the name P. i. biscayensis ssp. nov. (3) The Common and Iberian Chiffchaffs are very distinct in the contact zone. But an overall geographical variation following Bergmann's and Allen's rules within both taxa generates an ecomorphological convergence, i.e. P. i. ibericus and the populations of P. c. collybita from northern central Europe have similar sizes. This may explain why previous authors were unable to diagnose the two taxa on morphological criteria alone.
