The capuchinos are a group of birds in the genus Sporophila that has apparently radiated recently, as evidenced by their lack of mitochondrial genetic diversity. We obtained cytochrome c oxidase I (COI) sequences (or DNA barcodes) for the 11 species of the group and various outgroups. We compared the patterns of COI variability of the capuchinos with those of the largest barcode data set from neotropical birds currently available (500 species representing 51% of avian richness in Argentina… 
DNA Barcode Detects High Genetic Structure within Neotropical Bird Species
TLDR
It is shown that COI barcodes are a valuable tool to indicate which taxa would benefit from more extensive taxonomic revisions with multilocus approaches and support hypotheses that the megadiversity of birds in the region is associated with multiple geographic processes starting well before the Quaternary and extending to more recent geological periods.
Identifying the Sister Species to the Rapid Capuchino Seedeater Radiation (Passeriformes: Sporophila)
TLDR
The data suggest that the ancestor of the southern capuchinos is derived from northern South America and began to radiate during the lower to middle Pleistocene into at least eight species within the grasslands of northeastern Argentina, eastern Paraguay, and southern Brazil.
COI Barcoding of the Shorebirds: Rates of Evolution and the Identification of Species
TLDR
The interplay of evolutionary rates, divergence dates and gene flow appears to determine COI barcode differentiation between taxa.
MOLECULAR PHYLOGENETICS OF THE NEOTROPICAL SEEDEATERS AND SEED-FINCHES (SPOROPHILA, ORYZOBORUS, DOLOSPINGUS)
TLDR
The phylogenetic analysis reveals that Sporophila is paraphyletic with respect to Oryzoborus and the monotypic Dolospingus, and there is widespread convergence in basic plumage patterning among males of Neotropical seedeaters and seed-finches.
The multiple applications of DNA barcodes in avian evolutionary studies.
TLDR
These studies showed that DNA barcodes offer high-quality data well beyond their main purpose of serving as a molecular tool for species identification, including species that showed low genetic interspecific divergence and lack of reciprocal monophyly either are the result of recent radiation and (or) hybridize.
Barcoding South American Birds
TLDR
This study has shown that barcoding is highly efficient for species recognition in the southern Neotropics, allowing the recognition of more than 98% of bird species.
Hybridization between two recently diverged Neotropical passerines: The Pearly-bellied Seedeater Sporophila pileata, and the Copper Seedeater S. bouvreuil (Aves, Passeriformes, Thraupidae)
TLDR
It is demonstrated that the sexual selection mechanisms involved in the isolation of other reproductively sympatric capuchinos are not applicable to this pair of species, likely because of reduced barriers to mate recognition.
Molecular and plumage analyses indicate the incomplete separation of two woodpeckers (Aves, Picidae)
TLDR
It is indicated clearly that the two taxa form a single evolutionary unit, in which the morphological differentiation used to diagnose the species, combined with their geographic distribution, is at odds with the incomplete separation of the taxa.
Another color morph of Sporophila Seedeater from the capuchinos group (Aves, Emberizidae)
TLDR
It is concluded that this is another case of an intra-specific color morph within the seedeaters of the "capuchinos" group within the Neotropical region.

DNA BARCODING: CO1 DNA barcoding amphibians: take the chance, meet the challenge
TLDR
There is greater potential for a CO1 barcode's use with amphibians than has been reported to date and a large‐scale effort to barcode the amphibians of the world, using the same primary barcode region of CO1, will yield important findings for science and conservation.
Single mitochondrial gene barcodes reliably identify sister-species in diverse clades of birds
TLDR
Closely related sister species of birds can be identified reliably by barcodes of fixed diagnostic substitutions in COI sequences, verifying coalescent-based statistical tests of reciprocal monophyly for taxonomic distinctiveness and identifying recently separated lineages that represent putative species.

Molecular taxonomy of Brazilian tyrant‐flycatchers (Passeriformes: Tyrannidae)
TLDR
A great power of the COI barcodes to discriminate species of the Tyrannidae family that are found in Brazil is suggested.
SYSTEMATICS OF LARGE WHITE-HEADED GULLS: PATTERNS OF MITOCHONDRIAL DNA VARIATION IN WESTERN EUROPEAN TAXA
TLDR
Mitochondrial DNA was found to be strongly structured among species, indicating that mitochondrial gene flow is very low, and horizontal transfer of mitochondrial lineages is demonstrated or suspected between most taxa and obscured the reconstruction of the history of the group.
DNA barcodes distinguish species of tropical Lepidoptera.
TLDR
It is shown that cytochrome c oxidase I DNA barcodes effectively discriminate among species in three Lepidoptera families from Area de Conservación Guanacaste in northwestern Costa Rica, suggesting DNA barcoding will significantly aid species identification and discovery in tropical settings.
Comprehensive DNA barcode coverage of North American birds
TLDR
The consistent finding of constrained intraspecific mitochondrial variation in this large assemblage of species supports the emerging view that selective sweeps limit mitochondrial diversity.
Probing Evolutionary Patterns in Neotropical Birds through DNA Barcodes
TLDR
These findings confirm the efficacy of species delimitation in birds via DNA barcodes, even when tested on a global scale, and demonstrate how large libraries of a standardized gene region provide insight into evolutionary processes.
Countering criticisms of single mitochondrial DNA gene barcoding in birds
TLDR
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.
