Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

Journal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

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.

Concerted evolution of body mass and cell size: similar patterns among species of birds (Galliformes) and mammals (Rodentia)

Biology Open, 2018
Cell size plays a role in body size evolution and environmental adaptations. Addressing these roles, we studied body mass and cell size in Galliformes birds and Rodentia mammals, and collected published data on their genome sizes.

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

Journal of Anatomy, EarlyView.
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.

Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

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,

Species Determination Within the Felidae Family Using mtDNA Minibarcoding

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT Wildlife forensic analysis frequently deals with highly degraded DNA samples, including those from tanned hides, processed products of traditional Chinese medicine, and specimens stored in preservation fluids. These samples present significant challenges for traditional DNA barcoding due to the difficulty of amplifying sufficiently long DNA ...

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 ...

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 ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

Biological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
