The karyotypes of 39 avian species new to cytology are described, viz. Pelecanus crispus, P. occidentalis and Morus bassanus (Pelecaniformes), Ardea goliath, Ciconia episcopus and Leptoptilos javanicus (Ciconiiformes), Anas castanea, Anseranas semipalmata, Cereopsis novaehollandiae, Chloephaga rubidiceps and Netta rufina (Anseriformes), Falco jugger and Milvago chimachima (Falconiformes), Aepypodius arfakianus, A. bruijnii, Guttera plumifera, G. edouardi, Lophura edwardsi, L. imperialis and… 

A miscellaneous collection of bird karyotypes

TLDR
The karyotypes ofBurhinus magnirostris, Ceratogymna subcylindricus and C. bucinator exhibit the lowest diploid chromosome numbers hitherto found in birds, and almost completely lack microchromosomes.

A karyological study of Accipitridae (Aves: Falconiformes), with karyotypic descriptions of 16 species new to cytology

TLDR
Nine possible phylogenetic trees for the Accipitridae are constructed and the following points are remarkable in all possible karyological phylogenies: (1) the position of Pithecophaga is uncertain, it either represents an independent ancient lineage or is related to the Old World vultures; (2) Gypaetus probably is not related to, it rather evolved from an ancester in common with the booted eagles.

Karyotypic evolution in the Galliformes: An examination of the process of karyotypic evolution by comparison of the molecular cytogenetic findings with the molecular phylogeny

TLDR
The process of the evolutionary changes of macrochromosomes in the 13 species was in good accordance with the molecular phylogeny, and the ancestral karyotype of the Galliformes is represented.

Karyotypic characterization of Ramphastidae (Piciformes, Aves)

The karyotypes of nine species of the family Ramphastidae were determined and compared with that of the toco toucan (Ramphastos toco), the only ramphastid karyotype so far reported in the literature.

Comparative chromosome maps between the stone curlew and three ciconiiform species (the grey heron, little egret and crested ibis)

TLDR
The painting results indicate that different chromosome rearrangements occur in different ciconiiform lineages, and some of the small-sized bi-armed chromosomes in ACI, EGA and NNI are derived from the fusions of two microchromosomes, indicating that micro Chromosome fusions play an important role in ciconoiform chromosome evolution.

Karyotypic Characterization of Ten Species of Birds

The chromosomes of ten species of birds and their karyological relationships have been studied. These species are Gelochelidon nilotica 2n=60 and Larus genei 2n=54 (Family: Laridae), Himantopus

Cytotaxonomy of Eurypyga helias (Gruiformes, Eurypygidae): First Karyotypic Description and Phylogenetic Proximity with Rynochetidae

TLDR
The karyotype of the sunbittern is described for the first time, by classical and molecular cytogenetics, using whole chromosome probes derived from Gallus gallus and Leucopternis albicollis to suggest a close phylogenetic relationship between Eurypigidae and Rynochetidae, whose common ancestor was separated by the Gondwana vicariancy in South America and New Caledonia.

Chromosomal characterization of four antarctic procellariiformes

TLDR
The determination of chromosomal characteristics represents an important tool for conservation plans, as well as for phylogenetic and evolutionary studies of this class of birds.

Report on the karyology of three cytologically unknown birds: Surniculus lugubris, Orthotomus sutorius and Hippolais caligata

Karyological investigations of three birds: Surniculus lugubris dicruroides (Cuculidae, Cuculi-formes), Orthotomus sutorius guzuratus and Hippolais caligata caligata (Sylviidae, Passeriformes) were

Characterization of chromosome structures of Falconinae (Falconidae, Falconiformes, Aves) by chromosome painting and delineation of chromosome rearrangements during their differentiation

Karyotypes of most bird species are characterized by around 2n = 80 chromosomes, comprising 7–10 pairs of large- and medium-sized macrochromosomes including sex chromosomes and numerous

Cytotaxonomy of the Ciconiiformes (Aves), with karyotypes of eight species new to cytology

TLDR
Somatic karyotypes of 13 species of ciconiiform birds, including Phoenicopterus ruber chilensis, Phoeniconaias minor, Cochlearius cochlearius, Geronticus eremita, Threskiornis molucca, and Leptoptilos crumeniferus are presented and several characteristics in this group of chromosomes separate Balaenicipitidae from Ciconiidae are separate.

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, Calyptorhynchus magnificus and Probosciger aterrimus of the Cacatuidae, and Ara macao, A. ararauna,

The somatic chromosome complements of 16 species of falconiformes (Aves) and the karyological relationships of the order

TLDR
The variation in karyotypic structures found in the Falconiformes is much wider than that in other avian groups, however, it remains an unanswered question whether this karyological heterogenelty points to a polyphyletic origin of the diurnal birds of prey.

Somatic Chromosomes of the Congo Peafowl (Afropavo congensis) and Their Bearing on the Species' Affinities

TLDR
The chromosome complement of the Congo Peafowl is described and the presence of ectoparasites on Afropavo that are related to those of the African guineafowl, as well as species related to the Asiatic phasianids are discussed.

Chromosomal evolution of South American Columbiformes (Aves)

TLDR
Karyotypes are compared of 14 species of Brazilian Columbiformes and studies of relative lengths, arm ratios and G- and C-banding patterns showed that in Columbiforme pairs 3, 4 and 5 are the most stable.

A phylogenetic study of bird karyotypes

TLDR
A major role had been played by centric fission as well as fusion, translocation, and pericentric inversion in birds to elucidate mechanisms involved in certain structural changes of macrochromosomes observed in birds.

Chromosome studies in four species of Ratitae (Aves)

TLDR
Karyotypes of the 4 species were strikingly similar and apparently interchangeable with one another with slight modifications of the centromeric position in one or two pairs of macrochromosomes.

The karyograms of some Falconiformes and Strigiformes

TLDR
In all birds examined the female heterogametic sex has two heterochromosomes ZW, and the distribution of the haploid number frequencies is not normal, it is postulated that there are some factors limiting the random scattering of the values.

Chromosome banding studies of the razor-billed curassow, Crax mitu (Aves, Galliformes: Cracidae)

TLDR
The somatic chromosome complement of Cvav mitu was studied using conventional staining methods as well as Qand C-banding techniques and there seems to be a high degree of homology between chromosome morphology and banding patterns of both species and there are only a few minor differences in the macrochromosomes.
