First Record of Dark‐Sided Flycatcher (Muscicapa sibirica) for Temperate North America: Intercontinental Vagrancy and Migratory Misorientation

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We document the extraordinary occurrence of a Dark‐sided Flycatcher (Muscicapa sibirica)—a migratory passerine from East Asia—in California, USA. We discuss the little‐known phenomenon of intercontinental vagrancy in migratory landbirds and examine this case study in detail, providing analysis of the age, molt status, subspecies, and likely origins of ...

Spatial Differentiation Among Family Members of the Cooperatively Breeding Giant Babax Dynamically Adjusts to Temporal Fluctuations in Offspring Demand for Parental Care

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This research provided evidence that division of labor indeed occurred when offspring were in need of parental care. Therefore, labor division may serve as the underlying mechanism for different parental care strategies and movement patterns among group members in the cooperatively breeding system of giant babaxes.

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits

Oikos, Volume 2026, Issue 4, April 2026.
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing

Zoo Biology, Volume 45, Issue 2, Page 97-108, March/April 2026.
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.
