Abstract We compared sequences from two mitochondrial DNA (mtDNA) genes (ND2, ND3) in Savannah Sparrows (Passerculus sandwichensis; n = 112) sampled from Baja California (five sites), coastal Sonora and the continental range (eight sites). Populations from Baja California, San Diego and Sonora formed a clade within which there was no phylogeographic structure; this clade merits species status (Passerculus rostratus). The other clade, consisting of phenotypically “typical” savannah sparrows… 
Chapter 8: Phylogeography and Adaptive Plumage Evolution in Central American Subspecies of the Slate-Throated Redstart (Myioborus Miniatus)
TLDR
The genetic homogeneity within this clade suggests a late Pleistocene range expansion at a time when today's montane forest types existed at lower elevati...
Geographic Variation and Genetic Structure in the Streak-Backed Oriole: Low Mitochondrial DNA Differentiation Reveals Recent Divergence
TLDR
It is recommended that the insular populations of the Streak-backed Oriole be considered a separate species, Icterus graysonii, given the fixed differences from mainland birds in multiple characteristics, including mtDNA and plumage patterns.
Divergent mitochondrial lineages arose within a large, panmictic population of the Savannah sparrow (Passerculus sandwichensis)
TLDR
These analyses reject the interpretation that divergent, sympatric mtDNA lineages arose within a panmictic population of Savannah sparrows and underscore the need for genomic data sets to resolve the evolutionary mechanisms behind anomalous, locus‐specific patterns.
Morphological and molecular evolution and their consequences for conservation and taxonomy in the Le Conte's Thrasher (Toxostoma lecontei)
TLDR
Despite relatively weak morphological differences, it is suggested that these two deeply divergent lineages merit species status, and Vizcaino Thrasher for the common name corresponding to T. l.
The role of niche divergence and phenotypic adaptation in promoting lineage diversification in the Sage Sparrow (Artemisiospiza belli, Aves: Emberizidae)
TLDR
Palaeoclimatic niche models for the Last Glacial Maximum and the Last Interglacial suggest that ecoregionally distinct populations of Sage Sparrow experienced different Pleistocene range fluctuations and glacial refugia, with temporal niche conservatism.
Chapter 13: Alaska Song Sparrows (Melospiza Melodia) Demonstrate that Genetic Marker and Method of Analysis Matter in Subspecies Assessments
TLDR
Examination of genetic and morphological characteristics of the Song Sparrows of northwestern North America showed little information about these subspecies, with no reciprocal monophyly evident; however, differences in body mass and microsatellite allele frequencies supported continued recognition of subspecific units for taxonomy and conservation.
Comparative phylogenomic patterns in the Baja California avifauna, their conservation implications, and the stages in lineage divergence
TLDR
It is found that mitochondrial DNA, single nuclear genes, and genome-wide SNP data sets show largely concordant phylogeographic patterns for four bird species along the Baja California peninsula and adjacent mainland: cactus wren, Gila woodpecker, California gnatcatcher, and LeConte’s thrasher.
A revision of species limits in Neotropical pipits Anthus based on multilocus genetic and vocal data
TLDR
The species limits of Neotropical pipits Anthus are revised based on sequence data of mitochondrial (ND2) and nuclear genes from 39 tissue samples of all 22 subspecies-level taxa in the New World Anthus clade, as well as analysis of display song.
On the origin of the Galápagos hawk: an examination of phenotypic differentiation and mitochondrial paraphyly
TLDR
The results suggest directional selection on B. galapagoensis morphology associated with feeding, possibly an outcome of decreased interspecific competition and change towards a more generalist diet shared by B. jamaicensis.
Genetic and morphometric diversity in the Lark Sparrow (Chondestes grammacus) suggest discontinuous clinal variation across major breeding regions associated with previously characterized subspecies
TLDR
The results indicate that clinal variation among populations of long-distance migratory birds may reflect incipient evolutionary divergence, secondary contact zones, and local adaptation of populations to continuously variable environments.

PHYLOGEOGRAPHY OF SPOTTED OWL (STRIX OCCIDENTALIS) POPULATIONS BASED ON MITOCHONDRIAL DNA SEQUENCES: GENE FLOW, GENETIC STRUCTURE, AND A NOVEL BIOGEOGRAPHIC PATTERN
TLDR
The pattern of haplotype coalescence enabled us to identify the approximate timing and direction of a recent episode of gene flow from the Sierra Nevada to the northern coastal ranges, and the California spotted owl had substantially lower nucleotide diversity than the other two subspecies.
Geographic analysis of nucleotide diversity and song sparrow (Aves: Emberizidae) population history
TLDR

TLDR
Examining mitochondrial ND2 sequences in species of tits revealed a pattern of selection consistent with a model of mildly deleterious haplotypes, and it seems unlikely that most phylogeographic analyses are invalidated by the effects of natural selection.

General area cladogram suggests the following area relationships: Pacific and Caribbean Central America are sister areas, Choco is the sister to the Central American area, and Amazonia/southeastern Brazil is the outgroup area to the Choco/Central American clade.

A recent bottleneck, followed by serial bottlenecking during the process of post‐Pleistocene recolonization of northern Europe, together with recent population expansion provide a plausible explanation for the low genetic diversity in the north.

TLDR
A massive reorganization of classifications is required so that the lowest ranks, be they species or subspecies, reflect evolutionary diversity and until such reorganization is accomplished, the subspecies rank will continue to hinder progress in taxonomy, evolutionary studies and especially conservation.
