The foraging ecology and feeding behaviour of the grey heron (Ardea Cinerea) in the Camargue, S. France [PDF]

open access: yes, 1990
Foraging patterns of breeding Grey Herons were studied in the Camargue. Most individual birds used several different and widely dispersed feeding sites during the season.

Ecology and Brain Size Drive Feeding Innovations in Birds

open access: yesIntegrative Zoology, EarlyView.
Larger‐brained birds exhibit higher feeding innovation rates, but ecological factors shape different forms of innovation in distinct ways. Across 955 bird species, phylogenetic path analyses revealed that migration type and feeding strategy mediate the effects of brain size and climate on feeding innovations, illustrating how cognition and ecology ...

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

open access: yesJournal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Ardea

open access: yes, 2016
What is soul? Can it be forfeited? Can it be traded away? If it can, what would ensue? What consequences would follow from loss of soul — for the individual, for society, for the earth? In the early nineteenth century, Goethe’s hero, Faust, became a defining archetype of modernity, a harbinger of the existential possibilities and ...

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, Volume 42, Issue 8, Page 1799-1817, October 2026.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Morphological and Tissue Characterization with 3D Reconstruction of a 350-Year-Old Austrian Ardea purpurea Glacier Mummy

open access: yesBiology, 2023
Glaciers are dwindling archives, releasing animal mummies preserved in the ice for centuries due to climate changes. As preservation varies, residual soft tissues may differently expand the biological information content of such mummies. DNA studies have

Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

open access: yesConservation Science and Practice, Volume 8, Issue 10, October 2026.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...
