“…The evidence supports the view that both species are closely related, and that they have not diverged much at their enzyme loci since their separation. The slight differences found between the two taxa could be due to the relatively few specimens processed, although it is close to those observed in other bird species based upon more birds, more loci and more samples (Ross 1983;Parkin and Cole 1985;Evans 1987;van Wyk et al 1992 andBjordal et al 1986).…”

This paper reports a genetic study of Sturnus vulgaris and S. unicolor (Sturnidae), two similar bird species which have recently become sympatric in north-eastern Spain. Seven enzyme systems (alcohol dehydrogenase, esterase, glutamate dehydrogenase, glucose-6-phosphate dehydrogenase, leucin aminopeptidase, L-lactate dehydrogenase and superoxide dismutase) were analyzed, resolving 22 presumed genetic loci with 28 alleles; 27 of them were found in both species. Gene flow was estimated to be number of migrants per generation (Nm) = 6, and genetic identities among populations were high, ranging from I = 0.96 to I = 0.99. On the whole, the results demonstrate that these Sturnus populations share a gene pool, showing slight genetic differences between the two starling species.

“…Only two loci (Est-3 and Est-4) were polymorphic with three (two plus one null allele) and two alleles, respectively (Table 2). These enzymes have been widely employed in studies on genetic variability in birds (Ross 1983;Randi et al 1992;van Wyk et al 1992;Lougheed and Handford 1993).…”

“…The mean allozyme heterozygosity of many non‐passeriform bird species amounted to H = 0.035 (20 species investigated) and P = 0.244 (27 species analyzed; Evans 1987). Van Wyk et al (1992) encountered H = 0.039 over 34 electrophoretic loci in Cape Vulturs ( Gyps coprotheres ), and Morizot et al (1985) five polymorphisms in Bald Eagles ( Haliaeetus leucocephalus ), of which three systems at least displayed rather balanced frequencies. Schreiber & Weitzel (1995) observed allelic variation when screening two specimens of White‐tailed Eagle ( H. albicilla ) only.…”

Common Buzzard (Buteo buteo): A raptor with hyperpolymorphic plumage morphs, but low allozyme heterozygosity

The analysis of 25 allozyme loci in up to 469 Common Buzzards (B. b. buteo) from five locations in Germany revealed allelic polymorphism at twelve loci, but a prevalence of rare alleles resulted in a very low heterozygosity of H o = 0.0057. This rather low level of genetic variation characterizes a most abundant raptor species with highly polymorphic plumage pigmentation. The results of monitoring 571 buzzard breeding pairs from the Hakel forest (Sachsen-Anhalt) over 27 years indicate that neither the among-pair fertility variance, which slightly increased the genetically effective population size against the numerical size, nor the yearwise fluctuation of the breeder numbers, nor other population ecological characters were likely to erode the genetic variation of the numerically large buzzard population. One or repeated phyletic or historical bottle-necks are postulated to have diminished the allozyme variability, and at the same time to have created new genetic variance of the pigment-coding genes from non-additive components of genetic variance. Thus, the plumage colour diversity of the Common Buzzard could be a direct result of diminished single-locus genetic variation.
