Cranial osteology of Geotrygon montana (Linnaeus, 1758) (Columbiformes: Columbidae) compared to other New World Columbiformes [PDF]

Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2007
Studies on cranial osteology of Columbidae are not frequent in the literature. This is the first description of the jaw apparatus of G. montana and we had as objectives: to compare its jaw apparatus with other New World Columbidae and thus broaden our ...

Trichomonas Infection in a Community of Free-Ranging Domestic and Wild Columbiformes and Bonelli's Eagle (Aquila fasciata) [PDF]

Frontiers in Veterinary Science, 2019
Trichomonas gallinae is a pathogen of conservation relevance, whose main maintenance hosts are Columbiformes, but spillover to avian predators has been described. The goal of this study was to characterize the epidemiology of Trichomonas spp.

Constitutive Heterochromatin and the Structural Complexity of Chromosomes in Columbiformes and Psittaciformes (AVES)

Caryologia, 1983
SUMMARYStudies on the correlations between the length of the pericentromeric heterochromatin block and the internal structural complexity of chromosomes showed significance for some chromosomes both in Psittaciformes and Columbiformes. In Columbiformes, internal rearrangements resulting in translocation of portion of pericentromeric heterochromatin to ...

Relationship between carina size and sternum morphology in birds reflects physical constraints of body size and flight style. [PDF]

J Anat
Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.

Host Species Contribution to the Spatiotemporal Dynamics of the 2024-2025 H5N1 Epidemic in Italy. [PDF]

Influenza Other Respir Viruses
ABSTRACT This study uses a phylodynamic approach to investigate host species contribution in the spatiotemporal dynamics of the highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b identified during the 2024–2025 epidemic in Italy.

Multiple Strains of Trichomonas gallinae are Widespread in Reservoir Hosts and Environmental Resources in UK Farmland. [PDF]

Mol Ecol
ABSTRACT Understanding transmission routes of parasites and pathogens is critical for the development of control measures and mitigation of impacts on host populations. Trichomonas gallinae is a widespread parasite in columbids worldwide, and has emerged as a lethal disease in passerines, particularly finches.

Intensity of biparental care in Columbiformes and other selected bird taxa: a summary of the main ultimate and proximate mechanisms [PDF]

, 2023
Order Columbiformes is not very numerous group of birds but their importance for recent science and for people in general in significant. They are one of the most studied group of birds and knowledge we now have of parental care and proximal mechanisms ...
