Figure 3 in Non-breeding season records of the Alpine Leaf Warbler Phylloscopus occisinensis
Figure 3. Bayesian Inference phylogenetic trees based on COI (A) and Cytb (B) genes of collected samples and those downloaded from GenBank, with Yellow-streaked Warbler Phylloscopus armandii serving as an outgroup. Numbers on each node represent percent bootstrap values and posterior probabilities, respectively.

Figure 4. Spatial distribution of GRW nests and actual pairs on Bager Pond. Black dots represent GRW nests and ellipsoids indicate actual breeding pairs. Ellipsoids contain both successful and perished nests (dots) belonging to the same female. Ellipsoids containing 2 (1 original and 1 replacement clutch) or more dots show that 1 female raised 1 or more replacement clutches.

Golden-winged Warbler post-fledging movement and stand-scale habitat selection
<p>Our understanding of songbird habitat needs during the breeding season stems largely from studies of nest success. However, growing evidence shows that nesting habitat and post-fledging habitat often differ. Management guidelines for declining species need to be revaluated and updated to account for habitat shifts that may occur across the full breeding cycle. The Golden-winged Warbler (<i>Vermivora chrysoptera</i>) is a declining songbird species for which best management practices (BMPs) are based overwhelmingly on nesting habitat. We studied stand-scale habitat selection by fledgling Golden-winged Warblers during May-July 2014-2017 in two landscapes (2 years of data for each landscape), 200 km apart in Pennsylvania. Across four years, we radio-tagged and tracked 156 fledglings. We used discrete-choice models to evaluate habitat selection during two post-fledging time periods (days 1-5, days 6-28). Fledglings used a variety of cover types, but most telemetry relocations (i.e. 85%) occurred in forest in the stand initiation stage, stem exclusion stage, or mature forest upland. Fledglings primarily selected stand initiation forest during the first five days, but preferred habitats differed between regions during days 6-28 post-fledging.</p> <p>Fledglings in one landscape favored stands in the stem exclusion stage while fledglings in the other landscape continued to select stands in the initiation stage. Fledglings moved greater distances as they aged and dispersed approximately 750 m by day 28 post-fledging. These findings suggest the need to update Golden-winged Warbler BMPs to account for the broader habitat needs of fledglings during the breeding season. In addition, these results indicate that regional studies of habitat requirements can help guide management of dynamic forest landscapes for birds.</p>
Data from: Extensive hybridization between two Andean warbler species with shallow divergence in mtDNA
<p><span>Studying processes acting on differentiated populations upon secondary contact, such as hybridization, is important to comprehensively understand how species are formed and maintained over time. However, avian speciation studies in the tropical Andes have largely focused on the role of topographic and ecological barriers promoting divergence in allopatry, seldom examining hybridization and introgression. We describe a hybrid zone involving 2 closely related Andean warblers (Parulidae), the Golden-fronted Redstart (<i>Myioborus ornatus</i>)<i> </i>and the Spectacled Redstart (<i>Myioborus melanocephalus</i>). Geographic ranges of these species abut near the Colombia-Ecuador border and many specimens from the region exhibit intermediate phenotypes, but a formal description of phenotypic variation in the contact zone were heretofore lacking. We collected specimens across a transect encompassing the area where ranges abut and areas where only "pure" parental phenotypes of <i>M. ornatus chrysops </i>and <i>M. melanocephalus ruficoronatus</i> occur. We described variation in plumage traits including patterns of head and ventral coloration and tail markings based on 321 specimens. To describe genetic variation in the contact zone and over a broader phylogeographic context, we used sequences of the mitochondrial ND2 gene for 219 individuals across the transect and the entire range of both species, including all subspecies, from Venezuela to Bolivia. We documented a hybrid zone ~200 km wide based on head coloration, where intermediate plumage phenotypes are most common and "pure" forms do not overlap geographically, consistent with extensive hybridization. Across the range of the <i>M. ornatus</i>–<i>M. melanocephalus</i> complex, mitochondrial genetic structure was shallow, with genetic breaks only coinciding clearly with one topographic feature. Such<i> </i>low genetic structure is striking given the high diversity in plumage phenotypes and current taxonomy of the group<i>. </i>Our phenotypic data suggest that barriers to hybridization are not strong, and allow us to postulate hypotheses to be tested using forthcoming genomic data.</span></p>

Photos of a rare warbler hybrid, Yellow Warbler x Black-throated Blue Warbler (Setophaga petechia x Setophaga caerulescens)
<p>Hybridization can have profound effects on biological diversity; however, predictable inheritance of plumage traits remains poorly understood, especially for rare hybrids that are infrequently documented. We reviewed the literature and compiled a comprehensive list of hybrids from the wood warbler family Parulidae, a diverse radiation of songbirds with divergent plumage traits. We used our compilation to analyze modes of inheritance in wing bar patterns and carotenoid coloration. Finally, we described an unusual hybrid from the University of New Mexico in Albuquerque, New Mexico. We identified evidence of hybridization in 44 of 47 (93%) North American parulid species, with highest rates of hybridization in the genus <em>Setophaga</em>. We found predictable inheritance of plumage patterns between hybrid offspring and parental forms in our two focal traits, which supports the identification of our hybrid as a Yellow Warbler x Black-throated Blue Warbler (<em>S. petechia</em> x <em>S. caerulescens</em>). We based our identification on the extent and pattern of white in the tail, a prominent white wing flag, and our ability to confidently rule out all other alternative parentals. Our results suggest that some hybrid pairings can be confidently identified from phenotype alone, and that phenotypes of rare hybrid warblers likely have some degree of predictability.</p>
