Emerging Infectious Diseases, 2023 Salmonella infection causes epidemic death in wild songbirds, with potential to spread to humans. In February 2021, public health officials in Oregon and Washington, USA, isolated a strain of Salmonella enterica serovar Typhimurium from humans and a ...

Pathogens, 2020 Songbirds widely disperse ticks that carry a diversity of pathogens, some of which are pathogenic to humans. Among ticks commonly removed from songbirds, the blacklegged tick, Ixodes scapularis, can harbor any combination of nine zoonotic pathogens ...

Ecology and Evolution, 2021 Cross‐ecosystem subsidies move substantial amounts of nutrients between ecosystems. Emergent aquatic insects are a particularly important prey source for riparian songbirds but may also move aquatic contaminants, such as mercury (Hg), to riparian food ...

Programmed DNA elimination of germline development genes in songbirds
Nature Communications, 2019 Songbirds have extensive germline–soma genome differences due to developmental elimination of a germline-specific chromosome (GRC). Here, the authors show that the GRC contains dozens of expressed developmental genes, some of which have been on the GRC ...

The feasibility of counting songbirds using unmanned aerial vehicles
The AUK: A Quarterly Journal of Ornithology, 2017 Obtaining unbiased survey data for vocal bird species is inherently challenging due to observer biases, habitat coverage biases, and logistical constraints.

Journal of Comparative Physiology, 2022 The light-dependent magnetic compass sense of night-migratory songbirds can be disrupted by weak radiofrequency fields. This finding supports a quantum mechanical, radical-pair-based mechanism of magnetoreception as observed for isolated cryptochrome 4 ...

Mendelian nightmares: the germline-restricted chromosome of songbirds
Chromosome Research, 2022 Germline-restricted chromosomes (GRCs) are accessory chromosomes that occur only in germ cells. They are eliminated from somatic cells through programmed DNA elimination during embryo development.

Timing avian long-distance migration: from internal clock mechanisms to global flights [PDF]
, 2017 Migratory birds regularly perform impressive long-distance flights, which are timed relative to the anticipated environmental resources at destination areas that can be several thousand kilometres away.

Movement Ecology, 2020 Songbirds following distinct migration strategies (e.g. long- vs. short- to medium-distance migrants) often differ in their speed of migration during autumn and, thus, are assumed to face different time constraints.

Wireless battery free fully implantable multimodal recording and neuromodulation tools for songbirds
Nature Communications, 2020 Wireless battery free and fully implantable tools for the interrogation of the central and peripheral nervous system have quantitatively expanded the capabilities to study mechanistic and circuit level behavior in freely moving rodents.
