Abstract Songbird vocal behavior, physiology, and brains—including neurogenesis—change between seasons. We examined seasonal differences in neurogenesis in three brain regions associated with vocal production and learning, HVC (letter‐based proper name), robust nucleus of the arcopallium (RA), and Area X, and two brain regions associated with auditory ...

Abstract Seasonal song production in canaries is influenced by gonadal hormones, but the molecular mechanisms underlying testosterone‐induced song development in adult female canaries, which rarely sing naturally, remain poorly understood. We explored testosterone‐induced song development in adult female canaries by comparing gene regulatory networks ...

Hypotheses in light detection by vertebrate ancient opsin in the bird brain
Abstract Extra‐retinal photoreception is common across fish and avian species. In birds, the hypothalamus contains non‐visual photoreceptors that detect light and regulate multiple endocrine systems. To date, light‐dependent control of seasonal reproduction is one of the most well‐studied systems that require deep brain photoreception.

Abstract Birdsong learning and production is mediated through a vocal control circuit that exhibits ubiquitous and profound sex differences. In zebra finches (Taeniopygia guttata) only males sing, and sex differences in both neuroanatomy and myelination of this circuit emerge during the first 3 months of life as song learning is taking place.
