Summary: Enantiornithes, the most successful group of Mesozoic birds, may have evolved their extravagant tail plumage through sexual selection, resembling those in neornithines. The contrasting tail morphotypes between Enantiornithes and early Ornithuromorpha suggest unique pressures from sexual and natural selections. Early avialans repeatedly evolved extravagant structures, showcasing the importance of sexual selection in shaping feathered dinosaurs' plumage early in their evolutionary history.

Summary: The diet of Mesozoic birds has been poorly understood, but this study provides evidence suggesting that some of them were carnivorous and had adaptations for capturing and killing large prey. This challenges the prevailing view that Mesozoic birds mainly occupied low trophic levels and expands our understanding of their ecological niches.

Summary: Most crown-birds grow rapidly to adult size within a year, while the dominant Cretaceous terrestrial birds, Enantiornithes, had slower growth rates that continued into adulthood. However, the Late Cretaceous avisaurid enantiornithine, Mirarce eatoni, exhibited a unique growth strategy with relatively rapid growth. The osteohistological analysis of skeletal elements showed significant variation and complexity, indicating diverse growth strategies among Late Cretaceous enantiornithines.

Summary: The behavior of wild sulphur-crested cockatoos opening household waste bins in Sydney demonstrates cultural adaptation to urban environments. Analysis of community science reports indicates that this behavior spread through social learning across multiple suburbs in Sydney, showing individual styles and site-specific differences. This example highlights the potential of culture to facilitate adaptive behavioral responses to anthropogenic change.

Summary: The evolutionary history of birds shows three distinct large-scale increases in diversification rate, associated with accelerated morphological evolution among early stem birds, rapid evolution of the cranial skeleton among early crown birds, and influenced mainly by long-term climatic changes and major paleobiological events such as the Cretaceous-Paleogene (K-Pg) extinction.

Summary: The study characterizes the EDAA gene family in birds, suggesting it originated in an early archosaur ancestor and has expanded in birds, crocodiles, and turtles. The amino acid compositions of avian EDAAs are characteristic of structural functions associated with EDC genes and feather development. This supports the hypothesis that EDC genes have evolved through tandem duplication and diversification, contributing to the evolution of the intricate avian epidermis and epidermal appendages.

Summary: The Triassic and Early Jurassic herbivores are classified into five main guilds, generally avoiding competition by occupying different feeding groups. Major ecosystem remodelling was triggered by external environmental challenges, leading to the marginalisation of previously dominant herbivores by emerging forms. Dinosaur dominance was a mix of opportunity following disaster and competitive advantage in their new world.

Summary: This study investigates the tail-slapping behavior of an oblique water-entry projectile using high-speed photography technology. The experimental images and data are captured, extracted and processed using digital image processing. The study examines the impact of tail-slapping motion on the evolution of the projectile's cavity by analyzing its formation, development, and collapse process. It also explores the characteristics of the tail-slapping cavity and the original cavity at different initial water-entry speeds.

Summary: In this study, researchers describe a new enantiornithine bird fossil, Yatenavis ieujensis, which represents one of the youngest occurrences of this group in the Upper Cretaceous. The specimen, a distal half of a right humerus, was discovered in southern Santa Cruz Province, Argentina, and is the southernmost enantiornithine fossil found to date. Yatenavis possesses unique characteristics, some of which are shared with an unnamed enantiornithine from another fossil site in Patagonia.

Summary: By observing the data of Hα line and Ca II lines, we have derived the mass and density of a fan-shaped jet for the first time. The physical properties of the fan material are reasonably chromospheric in nature, but larger fan jets cannot be completely ruled out as potential drivers for sunquakes.

Summary: A new enantiornithine bird fossil from the Upper Cretaceous of China provides new insights into the osteology and cranial features of Late Cretaceous enantiornithines, showing that at least one lineage evolved cranial modifications similar to modern birds during the latest Cretaceous Period.

Summary: Feathers play a crucial role in the evolutionary history of birds due to their ability to perform multiple functions. By reviewing how feather functions interact with avian evolution, we gain a more comprehensive understanding of how birds adapt to diverse environments and develop various life-history strategies.

Summary: A new enantiornithine species, Musivavis amabilis, has been discovered in the Lower Cretaceous Jehol Biota in western Liaoning, China. This species shares similarities with bohaiornithids but also displays features associated with other enantiornithine lineages. Phylogenetic analysis reveals the impact of homoplasy on the reconstruction of enantiornithine relationships, yet Musivavis remains a member of the bohaiornithid-grade group.

Summary: This study reports a well-preserved skull and postcranium of the Middle Jurassic epoch (160 million years ago) haramiyidan Vilevolodon diplomylos, showing intact auditory ossicles. Comparing this fossil with other Mesozoic and extant mammals, the overlapping incudomallear articulation found in various groups of mammals is proposed to have evolved during the transition from dual to single function for the ossicles.

Summary: We described six specimens of ornithuromorph birds from the Changma locality in northwestern Gansu Province, China. These specimens provide insights into the taxonomy and dental morphology of ornithuromorph birds, and contribute to the understanding of the avifauna in this region. The observed dental variation suggests a trophic diversity similar to that found in ornithuromorphs from the Jehol Group in northeastern China.

Summary: The early diversification of birds in the Early Cretaceous had a significant impact on terrestrial ecosystems, with frugivorous birds playing an important role in seed dispersal. The discovery of fruit consumption in Jeholornis, one of the earliest-diverging birds, provides evidence for the involvement of birds in seed dispersal during the early stages of avian radiation.
