Supplementary Figures from Bare parts in the Galliformes: the evolution of a multifunctional structure

, 2023
A morphological trait can have multiple functions shaped by varying selective forces. Bare parts in birds, such as wattles, casques and combs, are known to function in both signalling and thermoregulation.

Seasonality, African Cherry occurrence, and human threats determine the spatial distribution of the endangered restricted range Mount Cameroon Francolin ( Pternistis camerunensis )

Avian Conservation and Ecology
The Mount Cameroon Francolin ( Pternistis camerunensis ) is a globally threatened and range restricted bird, which faces natural and human pressures that may alter its distribution and negatively affect its population size.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, Volume 249, Issue 4, Page 705-713, October 2026.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Variation in parrot jaw musculature

The Anatomical Record, Volume 309, Issue 9, Page 2519-2533, September 2026.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Mitigating Effects of Nest Structure on Predation Risk in Hainan Partridge (Arborophila ardens)

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Enclosed nest structures can disrupt predator search efficiency and reduce predation risk. Predation rate in the uncovered group was significantly higher than that in the covered group. Our study highlights the functional limitations of nest‐structure evolution within complex predation environments.

Phylogeny of major lineages of galliform birds (Aves: Galliformes) based on complete mitochondrial genomes

Genetics and Molecular Research, 2010
Complete mitochondrial DNA sequences have been used successfully to estimate phylogenetic relationships among animal taxa, and for studies of population genetics and molecular evolution. We made phylogenetic analyses of 22 species of Galliformes, with two species of Anseriformes as outgroups, using maximum likelihood (ML), maximum parsimony (MP) and ...

Joint telemetry and mark–recapture model reveal resource selection affects Northern Bobwhite chick survival

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Resource selection studies have become increasingly common since the advent of modern animal tracking equipment, yet most studies fail to examine how selection affects vital rates or population growth (i.e., fitness). Without investigating if optimal habitat selection is facilitated in a system, conservation efforts may promote ineffective ...

Estimating abundance of Galliformes: tools and application [PDF]

, 2001
A large number of techniques are available for assessing populations of vertebrates. However, application of many of those techniques to Galliformes is hampered by a variety of constraints.

Seasonal differences in dietary compositions of Blood Pheasant ( Ithaginis cruentus ): a study focuses on bryophytes from feces analysis

Journal of Field Ornithology
The Blood Pheasant ( Ithaginis cruentus ) may be unique amongst Galliformes species in that it is believed to forage primarily on bryophytes. Yet there are few quantitative studies that have examined the species diet and how this might vary seasonally ...

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...
