TL;DR: This work addresses criticisms of a single mtDNA gene barcodes in birds because most species are known and thus provide an ideal test data set, and argues with selected examples that with the exception of thresholds these criticisms are not problematic for avian taxonomy.

TL;DR: This work recovers a fully resolved topology placing rheas as the sister to kiwi and emu + cassowary that is congruent across marker types for two species tree methods (MP-EST and ASTRAL-II), and confirms the existence of an empirical anomaly zone in palaeognaths.

TL;DR: Peripherally isolated populations of common chaffinches in the Canaries, Madeira, and Azores were compared genetically with their putative ancestral stock in Iberia and Morocco, and with a population of blue chaffinch from Tenerife, using protein electrophoresis of 42 loci.

TL;DR: Variation within and between eight subspecies of Canada geese was assessed by restriction fragment analysis of mitochondrial DNA, electrophoresis of proteins encoded by nuclear DNA, and the morphometric analysis of skeletons.

TL;DR: In the context of song differentiation in New Zealand, the authors found that song types in an area are interconnected by different combinations of shared syllables, suggesting that the incorporation of some local syllables in a bird's repertoire is sufficient to signal its status as a member of a neighbourhood and also allows the evolution of broadcast complexity.
