Corvids (crows, magpies, jays) live in a close association with humans, and therefore knowledge about their population status and changes will be an essential part of monitoring the quality of urban environments.

Patterns of evolution of MHC class II genes of crows (Corvus) suggest trans-species polymorphism [PDF]
A distinguishing characteristic of genes that code for the major histocompatibility complex (MHC) is that alleles often share more similarity between, rather than within species.

Urban Birds Using Insects on Front Panels of Cars
Urbanization influences the food availability and quality for birds in many ways. Although a great amount of food for birds is provided incidentally or intentionally in urban areas, the quantity of insect-based food can be reduced in cities.

SummaryNieder, Wagener, & Rinnert (Science, 369(6511), 1626–1629, 2020) demonstrated that some neurons in a prefrontal-like brain area of carrion crows signal neither the physical stimulus nor the intended action but the upcoming choice. This pattern of results implies that neural computations for consciousness can be generated by nonmammalian ...

Occurrence of Chlamydiaceae in Raptors and Crows in Switzerland
Bacteria of the family Chlamydiaceae are globally disseminated and able to infect many bird species. So far, 11 species of Chlamydia have been detected in wild birds, and several studies found chlamydial strains classified as genetically intermediate ...

Strong between-site variation in New Caledonian crows' use of hook-tool-making materials [PDF]
The study was funded through a BBSRC David Phillips Fellowship (grants BB/G023913/1 and BB/G023913/2 to CR) and doctoral studentships from the BBSRC (BK), JASSO (SS), and the School of Biology, University of St Andrews (JvdW).Functional tool use requires

There is limited understanding of how patella realignment or patellectomy to surgically manage patellofemoral pain (PFP) affects knee biomechanics. By analysing marsupials like kangaroos that lack an ossified patella, actionable biomimetic insight for ...

Theory of coupled resonator optical waveguides exhibiting high-order exceptional points of degeneracy [PDF]
We present an approach and a theoretical framework for generating high-order exceptional points of degeneracy (EPDs) in photonic structures based on periodic coupled resonator optical waveguides (CROWs). Such EPDs involve the coalescence of Floquet-Bloch

Tunable delay lines in silicon photonics: coupled resonators and photonic crystals, a comparison [PDF]
In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as tunable delay lines.
