“…In the literature references are found to three members of the Caprimulgidae (Bulatova et al, 1971;Kaul & Ansari, 1983;De Lucca & Waldrigues, 1983), but to date detailed information on karyotypic structure is unavailable for them. The present authors studied the chromosomes of Podargus strigoides, belonging to the Podargidae.…”

Birds are characterized by a low proportion of repetitive DNA in their genome when compared to other vertebrates. Among birds, species belonging to Piciformes order, such as woodpeckers, show a relatively higher amount of these sequences. The aim of this study was to analyze the distribution of different classes of repetitive DNA—including microsatellites, telomere sequences and 18S rDNA—in the karyotype of three Picidae species (Aves, Piciformes)—Colaptes melanochloros (2n = 84), Colaptes campestris (2n = 84) and Melanerpes candidus (2n = 64)–by means of fluorescence in situ hybridization. Clusters of 18S rDNA were found in one microchromosome pair in each of the three species, coinciding to a region of (CGG)10 sequence accumulation. Interstitial telomeric sequences were found in some macrochromosomes pairs, indicating possible regions of fusions, which can be related to variation of diploid number in the family. Only one, from the 11 different microsatellite sequences used, did not produce any signals. Both species of genus Colaptes showed a similar distribution of microsatellite sequences, with some difference when compared to M. candidus. Microsatellites were found preferentially in the centromeric and telomeric regions of micro and macrochromosomes. However, some sequences produced patterns of interstitial bands in the Z chromosome, which corresponds to the largest element of the karyotype in all three species. This was not observed in the W chromosome of Colaptes melanochloros, which is heterochromatic in most of its length, but was not hybridized by any of the sequences used. These results highlight the importance of microsatellite sequences in differentiation of sex chromosomes, and the accumulation of these sequences is probably responsible for the enlargement of the Z chromosome.

“…The karyotypes of nine species of the order have been previously studied in some detail, viz. Melopsittacus undulatus (Van Brink, 1959;Rothfels et al, 1963;Ohno et aL, 1964;De Lucca, 1977), Psittacula krameri, P. cyanocephala and P. alexandri (Ray-Chaudhuri et al, 1969; the latter species also by Kaul & Ansari, 1983), Nestor notabilis, A mazona ochrocephala and Psittacus erithacus (De Boer & Belterman, 1980) and Brotogeris sanctithomae (De Lucca, 1974). In addition, De 110 Lucca (1981) studied five species of Aratinga and one of Forpus, but reported no details of karyotypic structure.…”

Chromosome studies of 8 species of parrots of the families Cacatuidae and Psittacidae (Aves: Psittaciformes)

The karyotypes of 7 species of Psittaciformes new to cytology are described: Cacatua galerita, Caly_pto-rhynchus magnificus and Probosciger aterrimus of the Cacatuidae, and Ara macao, A. ararauna, Amazona viridigenalis and Psittrichas fulgidens of the Psittacidae. For reasons of comparison the karyotype of Melopsittacus undulatus is also described. These karyotypes are compared to 8 psittaciform karyotypes previously recorded. There is a remarkable heterogeneity of karyotypes in the Psittaciformes. Nevertheless, it seems possible to recognize Cacatua, Calyptorhynchus and probably also Probosciger (Cacatuidae) by their karyotypes as a dearly related group. The karyotypes of these cacatuids also bear some resemblance to that of Loriculus (Psittacidae). The psittacid genera Amazona, Ara, Nestor, Melopsittacus, Psittaeula, Psittacus and Psittrichas are karyologically heterogeneous, but their karyotypes show certain relationships. The karyotype of Brotogeris is very different from those of other psittacids.
