Alston's singing mice, found in Central America's highland cloud forests, are known for their complex vocalizations that serve social functions like territory defense and mate attraction. These mice engage in "sing-offs" to avoid physical confrontations, using precise neural circuits similar to those in humans and songbirds. Their high-pitched songs are an adaptation to avoid predators and are studied for insights into communication and speech disorders, highlighting the evolutionary parallels in vocalization across species.

A new study led by neuroscientist Diana Liao reveals that crows can count out loud, demonstrating sophisticated numerical abilities and vocal control. The research shows that crows can produce specific numbers of vocalizations in response to numerical cues, similar to how human toddlers learn to count. This discovery suggests that crows, and potentially other birds, may possess more advanced cognitive skills than previously thought, prompting further research into avian intelligence and communication.

A new study reveals that crows can count out loud, demonstrating numerical abilities and vocal control comparable to human toddlers. Researchers found that crows could reliably count to four with their caws, suggesting they might be able to go higher if needed. This discovery highlights the sophisticated cognitive skills of crows, using a nonsymbolic number estimation system shared by humans and animals.

A study by researchers at the University of Tübingen has shown that crows can plan and control the number of calls they make, demonstrating advanced numerical competence and vocal control. The crows were able to produce a specific number of calls in response to visual or auditory stimuli, indicating they form an abstract numerical concept to plan their vocalizations. This ability suggests sophisticated communication potential in crows.

Recent studies by researchers from The University of Texas at Austin have discovered a genetic link between the syrinx, the vocal organ of birds, and the larynx, the vocal organ of mammals, reptiles, and amphibians. This connection, termed "deep homology," reveals that these organs share the same developmental programming. The research, which includes high-resolution scans of syrinxes from various bird species, suggests that the common ancestor of modern birds had a syrinx with two sound sources, potentially allowing for diverse vocalizations. The findings provide new insights into the evolution of vocal organs and their genetic underpinnings.

A new study reveals that crows can count out loud, producing a specific number of caws in response to visual and auditory cues. This ability, which requires both numerical understanding and vocal control, has not been observed in other non-human species. The research, conducted on three carrion crows, shows that they can flexibly produce between one and four vocalizations, similar to how human toddlers count before mastering symbolic numbers. This discovery could indicate a new form of avian communication and suggests an evolutionary precursor to true counting.

Researchers have identified a brain circuit that coordinates vocalization with breathing, ensuring speech occurs predominantly during exhalation. This circuit, regulated by a brainstem area responsible for breathing rhythm, receives inhibitory signals during inhalation, preventing speech. The study, conducted in mice, sheds light on the neurological control of speech and breathing coordination, suggesting a shared mechanism across species, including humans.
