“…We used ND2 sequence data from GenBank and the sequence data generated for this project to build a phylogeny of the genus Plegadis and close relatives with available sequence data from prior work (Ramirez, Miyaki, & Del Lama, 2013; see Supporting Information Table S2 for GenBank accession numbers). To determine the best-fit finite-sites substitution model for the data set, we used jmodeltest 2.1.6 (Darriba, Taboada, Doallo, & Posada, 2012).…”

Evolutionary dynamics of hybridization and introgression following the recent colonization of Glossy Ibis (Aves: Plegadis falcinellus) into the New World

Geographic range shifts can cause secondary contact and hybridization between closely related species, revealing mechanisms of species formation and integrity. These dynamics typically play out in restricted geographic regions, but highly vagile species may experience major distributional changes resulting in broad areas of contact. The Glossy Ibis (Plegadis falcinellus) is a dispersive waterbird of the Old World and Australia that colonized eastern North America in the early 19th century and came into contact with the native White‐faced Ibis (P. chihi). Putative hybrids between the two species have been observed across North America. To examine the population genomic consequences of this natural invasion, we sequenced 4,616 ultraconserved elements from 66 individuals sampled across the distributions of falcinellus, chihi, and the Puna Ibis (P. ridgwayi) of South America. We found genomic differentiation among the three species. Loci with high sequence divergence were often shared across all pairwise species comparisons, were associated with regions of high nucleotide diversity, and were concentrated on the Z chromosome. We detected signals of genetic admixture between chihi and falcinellus in individuals both near and far from their core area of sympatry. Genomic cline analyses revealed evidence of greater introgression into falcinellus from chihi, but we found little evidence for selection against hybrids. We also found signals of admixture between ridgwayi and South American populations of chihi. Our results indicate vagile species can experience pervasive introgression upon secondary contact, although we suggest these dynamics may be more ephemeral than the stable hybrid zones often observed in less dispersive organisms.

“…In the Threskiornithidae, a well‐developed, rod‐shaped uncinate bone is present in Plegadis , Platalea , and Threskiornis , which is notable, because molecular analyses suggest a clade including these three taxa (Ramirez et al, 2013). However, in some taxa, the ossicle appears to be co‐ossified with the ectethmoid ( Bostrychia hagedash ) and others show vestiges of an uncinate bone.…”

A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles-which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)-were already described two centuries ago, but knowledge of their distribution and morphological variability in higher level clades is incomplete. In the present study, a detailed survey of the occurrence of uncinate bones is given, and these ossicles are for the first time reported in the gruiform Psophiidae, some Rallidae, and in the Otidiformes. Their presence in the latter taxon is of particular interest, because in current molecular analyses, the Otidiformes result as close relatives of the Musophagiformes, in which the uncinate bone is particularly large. The uncinate bones of most other neornithine clades, however, appear to have evolved multiple times independently through parallel evolution from the same ligamentous structures. A few earlier authors assumed that the uncinate bone is homologous to the ectopterygoid of non-avian theropods. Although this remains a viable hypothesis, more data on the occurrence of the ectopterygoid in Mesozoic birds are needed for well-supported conclusions. Here, it is noted that the ontogenetic development of the uncinate bone appears to be correlated with that of the ectethmoid, which is another bone in the skull of neornithine birds that is of unknown origin.

Mayr, G. 2016. Variations in the hypotarsus morphology of birds and their evolutionary significance -Acta Zoologica (Stockholm) 97: 196-210. Crown group (neornithine birds) exhibit a great variation in the morphology of the hypotarsus, a structure on the proximal end of the tarsometatarsus, which guides the tendons of the flexor muscles of the toes. Hypotarsus morphology is of significance for the identification of fossil taxa, and several extant groups show characteristic patterns that are of phylogenetic interest. So far, however, the diversity of hypotarsus morphologies has been little studied, and there are no comprehensive studies across all neornithine birds. In particular, the identities of the involved canals and sulci remain elusive, and some confusion exists about their correct homologies. In this study, hypotarsus morphologies are for the first time surveyed among all extant birds, and basic patterns are characterized. Instances are identified, in which particular hypotarsus morphologies are correlated with certain locomotion types, inferences are made about possible ancestral morphologies, and some patterns of phylogenetic interest are discussed.Osteological comparisons are based on skeletons in the collection of the Senckenberg Research Institute Frankfurt and the American Museum of Natural History (AMNH; few passerines). In many cases, identification of the number of tendons running through particular canals or sulci was facilitated by the examination of incompletely macerated specimens with the dried tendons still in place. For Phalacrocorax carbo, tendinal identity was verified by dissection of a fresh bird. Particular attention has been paid to the selection of adult birds for the examination of hypotarsus morphology. Examined skeletonsConcerning extant taxa, the bony hypotarsus of the following taxa was studied (the sequence of non-passeriform taxa follows Cracraft 2013):Comparative hypotarsus morphology Mayr Acta Zoologica (Stockholm) 97: 196-210 (April 2016)
