Every fall, these tiny 12-gram birds make a nonstop transatlantic flight from upper Canada to South America. Then, the fol- lowing spring, they reverse migrate to their breeding grounds. A few hours later, I checked on this exquisite feathered jewel. He was no longer quiet. I could hear him bouncing against the box top in a frenzied urge to leap up and fly south. I let him go and off he went—toward the Statue of Liberty, a fitting testament to his fortitude. I hoped that I had helped him a little.

Genomic Variation Across the Yellow-Rumped Warbler Species Complex
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2016 Genomic variation across the Yellow-rumped Warbler species complex Toews, David P L ; Brelsford, Alan ; Grossen, Christine ; Milá, Borja ; Irwin, Darren E Abstract: Populations that have experienced long periods of geographic isolation will diverge over time. The application of highthroughput sequencing technologies to study the genomes of related taxa now allows us to quantify, at a fine scale, the consequences of this divergence across the genome. Throughout a number of studies, a notable pattern has emerged. In many cases, estimates of differentiation across the genome are strongly heterogeneous; however, the evolutionary processes driving this striking pattern are still unclear. Here we quantified genomic variation across several groups within the Yellow-rumped Warbler species complex (Setophaga spp.), a group of North and Central American wood warblers. We showed that genomic variation is highly heterogeneous between some taxa and that these regions of high differentiation are relatively small compared to those in other study systems. We found that theclusters of highly differentiated markers between taxa occur in gene-rich regions of the genome and exhibitlow within-population diversity. We suggest these patterns are consistent with selection, shaping genomic divergence in similar genomic regions across the different populations. Our study also confirms previous results relying on fewergenetic markers that several of the phenotypically distinct groups in the system are also genomically highly differentiated, likely to the point of full species status.

Defining a Monophyletic Cardinalini
Available online at www.sciencedirect.com Molecular Phylogenetics and Evolution 45 (2007) 1014–1032 www.elsevier.com/locate/ympev Defining a monophyletic Cardinalini: A molecular perspective John Klicka a,*, Kevin Burns b, Garth M. Spellman a,1 a Barrick Museum of Natural History, Box 454012, University of Nevada Las Vegas, 4505 Maryland, Parkway, Las Vegas, NV 89154-4012, USA b Department of Biology, San Diego State University, San Diego, CA 92182-4614, USA Received 28 March 2007; revised 29 June 2007; accepted 10 July 2007 Available online 19 July 2007 Abstract Within the New World nine-primaried oscine assemblage, feeding morphology and behavior have long been used as a guideline for assigning membership to subgroups. For example, birds with stout, conical bills capable of crushing heavy seeds have generally been placed within the tribe Cardinalini (cardinal-grosbeaks). Many workers have tried to characterize this group more definitively, using a variety of morphological characters; however, the characters used often conflicted with one another. Previous molecular studies addressing the monophyly of Cardinalini have had only limited sampling within the group. In this study, we analyze mtDNA sequence data from all genera and 34 of the 42 Cardinalini species (sensu [Sibley, C.G., Monroe, B.L., 1990. Distribution and Taxonomy of the Birds of the World, Yale University Press, New Haven, CT]) to address the monophyly of the group and to reconstruct the most com- plete phylogeny of this tribe published to date. We found strong support for a redefined Cardinalini that now includes some members previously placed within Thraupini (tanagers; the genera Piranga, Habia, Chlorothraupis, and Amaurospiza) and some members previ- ously placed within the Parulini (wood-warblers; the genus Granatellus). -
Interspecific Social Dominance Mimicry in Birds
bs_bs_banner Zoological Journal of the Linnean Society, 2014. With 6 figures Interspecific social dominance mimicry in birds RICHARD OWEN PRUM1,2* 1Department of Ecology and Evolutionary Biology, Yale University, New Haven, CT 06520-8150, USA 2Peabody Natural History Museum, Yale University, New Haven, CT 06520-8150, USA Received 3 May 2014; revised 17 June 2014; accepted for publication 21 July 2014 Interspecific social dominance mimicry (ISDM) is a proposed form of social parasitism in which a subordinate species evolves to mimic and deceive a dominant ecological competitor in order to avoid attack by the dominant, model species. The evolutionary plausibility of ISDM has been established previously by the Hairy-Downy game (Prum & Samuelson). Psychophysical models of avian visual acuity support the plausibility of visual ISDM at distances ∼>2–3 m for non-raptorial birds, and ∼>20 m for raptors. Fifty phylogenetically independent examples of avian ISDM involving 60 model and 93 mimic species, subspecies, and morphs from 30 families are proposed and reviewed. Patterns of size differences, phylogeny, and coevolutionary radiation generally support the predic- tions of ISDM. Mimics average 56–58% of the body mass of the proposed model species. Mimics may achieve a large potential deceptive social advantage with <20% reduction in linear body size, which is well within the range of plausible, visual size confusion. Several, multispecies mimicry complexes are proposed (e.g. kiskadee- type flycatchers) which may coevolve through hierarchical variation in the deceptive benefits, similar to Müllerian mimicry. ISDM in birds should be tested further with phylogenetic, ecological, and experimental investigations of convergent similarity in appearance, ecological competition, and aggressive social interactions between sympatric species. -

Scott Ranger www.scottranger.com, [email protected] Production Notes This is very much a work under construction. My notes are composed in Adobe InDesign which allows incredible precision of all the elements of page layout. My choice of typefaces is very specific. Each must include a complete set of glyphs and extended characters. For my etymologies the font must include an easily recognized Greek and the occasional Cyrillic and Hebrew. All must be legible and easily read at 10 points. Adobe Garamond Premier Pro is my specifically chosen text typeface. I find this Robert Slimbach 1989 revision of a typeface created by Claude Garamond (c. 1480–1561) to be at once fresh and classic. Long recognized as one of the more legible typefaces, I find it very easy on the eye at the 10 point size used here. I simply adore the open bowls of the lower case letters and find the very small counters of my preferred two- storied “a” and the “e” against its very open bowl elegant. Garamond’s ascenders and decenders are especially long and help define the lower case letters with instant recognition. -
Paraguayan Mega! (Paul Smith)
“South America’s Ivorybill”, the Helmeted Woodpecker is a Paraguayan mega! (Paul Smith) PARAGUAY 15 SEPTEMBER – 2 OCTOBER 2017 LEADER: PAUL SMITH With just short of 400 birds and 17 mammals Paraguay once again proved why it is South America’s fastest growing birding destination. The "Forgotten Heart of South America", may still be an “off the beaten track” destination that appeals mainly to adventurous birders, but thanks to some easy walking, stunning natural paradises and friendly, welcoming population, it is increasingly becoming a “must visit” country. And there is no wonder, with a consistent record for getting some of South America’s super megas such as Helmeted Woodpecker, White-winged Nightjar, Russet-winged Spadebill and Saffron-cowled Blackbird, it has much to offer the bird-orientated visitor. Paraguay squeezes four threatened ecosystems into its relatively manageable national territory and this, Birdquest’s fourth trip, visits all of them. As usual the trip gets off to flyer in the humid and dry Chaco; meanders through the rarely-visited Cerrado savannas; indulges in a new bird frenzy in the megadiverse Atlantic Forest; and signs off with a bang in the Mesopotamian flooded grasslands of southern Paraguay. This year’s tour was a little earlier than usual, and we suffered some torrential rainstorms, but with frequent knee-trembling encounters with megas along the way it was one to remember. 1 BirdQuest Tour Report: Paraguay www.birdquest-tours.com Crakes would be something of a theme on this trip, and we started off with a belter in the pouring rain, the much sought after Grey-breasted Crake.
