  • Molt and Age Determination in Western and Yellowish Flycatchers
    MOLT AND AGE DETERMINATION IN WESTERN AND YELLOWISH FLYCATCHERS N•D K. Jo•so• T•N years ago I presenteda review of researchon molts in tyrannid flycatchersof the genusEmpidonax, in a paper that includedoriginal data for five species(Johnson 1963b). Since that time very little has beenpublished on this aspectof the biologyof theseflycatchers, although Mumford (1964: 46) and Traylor (1968) have added new details to data availablefor the AcadianFlycatcher (Empidonaxvirescens). In the presentpaper I describemolt patternsand criteria for determin- ing age in two close relatives in the genus Empidonax, the Western Flycatcher (E. difficilis) and the YellowishFlycatcher (E. fiavescens). The molts of thesespecies have not been studiedpreviously in any de- tail. This work was undertakento gatherbackground information neces- sary for the proper interpretation of size variation in a systematic analysisof this difficult group (JohnsonMS). Finally I considerpat- terns and progressof cranial developmentin these flycatchers and of- fer a new hypothesisto explain retardedpneumatization of the skull roof in birds. MATERIALS AND METgODS Approximately 2,100 specimensof both species,representing all seasonsand areas of geographicoccurrence, were examined carefully under a magnifying lamp for evidence of molt and to determine degrees of plumage wear. Study was facilitated by the concurrentuse of a strong microscopelamp to illuminate feather bases while rows of feathers were parted with a dissecting needle. Molt stages used are the same as those defined for Empidonax hammondi• (Johnson 1963a: 124-128). For the Western Flycatcher, emphasisis on E. d. difficilis, the form for which sufficient samples are available. Most migrating and wintering examples of the nominate race may be separated by features of size and coloration from resident Mexican forms of the species(Johnson MS).

  • Molecular Taxonomy of Brazilian Tyrant-Flycatchers (Passeriformes: Tyrannidae)
    Molecular Ecology Resources (2008) 8, 1169–1177 doi: 10.1111/j.1755-0998.2008.02218.x DNABlackwell Publishing Ltd BARCODING Molecular taxonomy of Brazilian tyrant-flycatchers (Passeriformes: Tyrannidae) A. V. CHAVES, C. L. CLOZATO, D. R. LACERDA, E. H. R. SARI* and F. R. SANTOS Departamento de Biologia Geral, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, CP 486, 31270-901, Belo Horizonte, Minas Gerais, Brazil Abstract The tyrannids are one of the most diverse groups of birds in the world, and the most numerous suboscine family in the Neotropics. Reflecting such diversity, many taxonomic issues arise in this group, mainly due to morphological similarities, even among phylogenetically distant species. Other issues appear at higher taxonomic levels, mostly brought up by genetic studies, making systematics a rather inconclusive issue. This study looks into the use of DNA barcodes method to discriminate and identify Tyrannidae species occurring in the Atlantic Forest and Cerrado biomes of Brazil. We analysed 266 individuals of 71 tyrant-flycatcher species from different geographical locations by sequencing 542 bp of the mtDNA COI gene. The great majority of the analysed species showed exclusive haplotypes, usually displaying low intraspecific diversity and high interspecific divergence. Only Casiornis fuscus and Casiornis rufus, suggested in some studies to belong to a single species, could not be phy- logenetically separated. High intraspecific diversity was observed among Elaenia obscura individuals, which can suggest the existence of cryptic species in this taxon. The same was also observed for Suiriri suiriri, considered by some authors to comprise at least two species, and by others to be divided into three subspecies.
