Wolf‐Dog Hybrids Are More Fearful but as Social and Playful as Dogs
Ethology, Volume 131, Issue 10, Page 187-197, October 2025.In order to understand how behavior changed during dog domestication, we used wolf‐dog hybrids as a proxy for wolves and compared their behavior in several test situations with that of the dog breeds they were mixed with. Wolf‐dog hybrids were similar to the dogs in sociability, playfulness, and aggression, but showed significantly more long‐lasting ...

Perception of missing fundamentals in zebra finches and Bengalese finches.
Journal of the Acoustical Society of Japan (E), 2000 Perception of missing fundamental is widespread in vertebrate animals but seldom it is discussed with the relationship with vocal signals used by the animals.We tested the perception of missing fundamentals in two species of closely related finches with widely different vocal signals.Zebra finches and Bengalese finches were trained, in a Go-Nogo ...

Past research and future directions in understanding how birds use their sense of smell
Ibis, Volume 167, Issue 4, Page 853-881, October 2025.Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Frontiers in Computational Neuroscience, 2011 How the brain learns and generates temporal sequences is a fundamental issue in neuroscience. The production of birdsongs, a process which involves complex learned sequences, provides researchers with an excellent biological model for this topic.

Ibis, Volume 167, Issue 4, Page 1028-1042, October 2025.Bird song is an important and variable sexual signal in many passerine species. One function of this variability may be that males show mate choice and can alter their song according to the quality of the female to which they are singing. If attractive songs are costly, we can hypothesize that males sing more attractively or invest more in singing when

Diet and birdsong: short‐term nutritional enrichment improves songs of adult Bengalese finch males
Journal of Avian Biology, 2016 Song is a notable sexual signal of birds, and serves as an honest indicator of male quality. Condition dependence of birdsong has been well examined from the viewpoint of the developmental stress hypothesis, which posits that complex songs assure fitness

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection
BioEssays, Volume 47, Issue 9, September 2025.Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Ecology and Evolution, Volume 15, Issue 9, September 2025.How do birds develop their unique vocal repertoires, and how do these vary across populations? Using machine learning and bioacoustics, we analyzed the vocalizations of the White Spectacled Bulbul, revealing population‐specific motifs built from shared syllables.

European Journal of Neuroscience, Volume 61, Issue 9, May 2025.Although female zebra finches do not learn vocalizations, they possess brain structures analogous to those of males that use these structures to learn a large part of their vocal output, such as song. We wirelessly recorded neural signals from one of these brain areas, premotor nucleus RA, simultaneously with the vocal output from freely behaving ...

Exploring Anatomical Links Between the Crow's Nidopallium Caudolaterale and Its Song System
Journal of Comparative Neurology, Volume 533, Issue 2, February 2025.The crow's nidopallium caudolaterale (NCL) projects densely to the dorsal intermediate arcopallium (AID) and the striatum, paralleling important song system pathways. Connections from the magnocellular nucleus of the anterior nidopallium (MAN) to NCL and HVC run in parallel but remain distinct.
