Convergent and lineage-specific genomic changes shape adaptations in sugar-consuming birds

The paper identifies convergent and lineage-specific genomic changes in sugar-feeding birds through genome and transcriptome analyses, revealing adaptive mechanisms in metabolic pathways.

Programmed DNA elimination drives rapid genomic innovation in two thirds of all bird species

The paper identifies germline-restricted chromosomes (GRCs) in 6,700 passerine species, showing rapid evolution and functional gene retention despite programmed DNA elimination.

From silence to song: Testosterone triggers extensive transcriptional changes in the female canary HVC

This study shows testosterone induces extensive transcriptional changes in the female canary's HVC, with 9,913 genes differentially expressed over two weeks, linked to neuronal and cellular processes.

Evolution of vocal production learning in parrots

This study surveys video footage to assess vocal production learning (VPL) across parrot species, finding evidence of VPL in 136 of 163 surveyed species and identifying socio-ecological factors associated with its evolution.

The gene expression profile of the song control nucleus HVC shows sex specificity, hormone responsiveness, and species specificity among songbirds

The paper examines sex-specific gene expression in the HVC of songbirds, finding that sex and hormone levels significantly influence transcriptomes, with differences observed between natural and testosterone-induced singing.

Highly efficient genome modification of cultured primordial germ cells with lentiviral vectors to generate transgenic songbirds

This study generates transgenic songbirds by efficiently modifying zebra finch primordial germ cells with lentiviral vectors.

Fast retrograde access to projection neuron circuits underlying vocal learning in songbirds

The paper introduces a viral tool for fast retrograde labeling of projection neurons in songbirds and mice, enabling detailed analysis of vocal learning circuits.

Singing-related reorganization of the song motor circuit is accompanied by a shift in hormonal modulation of song

This study shows that DHT can re-acquire high-quality songs in experienced canaries but not naive females, indicating hormonal modulation of song circuits changes with vocal practice.
