Figure 1 in Natural history of the Lined Seedeater Sporophila lineola (Aves: Thraupidae) in southeastern Brazil
Figure 1. Number of nests of the Lined Seedeater Sporophila lineola found during the first (2014/ 2015, above) and second (2015/2016, below) breeding seasons studied in the Campus Florestal da Universidade Federal de Viçosa, Minas Gerais, Brazil. Each month was subdivided into three 10-day periods (I, II and III). Each nest was counted only once in each stage: nest with eggs (laying of the first egg) and nests with nestlings (hatching of the first egg).
New set of microsatellite markers for the great-billed seed-finch (Sporophila maximiliani – Passeriformes: Thraupidae): tools for inspection and conservation
<p>The Thraupidae family is one of the most wanted by bird breeders in Brazil due to its diverse, colorful and melodious singers as representatives. The Great-billed Seed-finch, Sporophila maximiliani, is the only representative of the genus Sporophila considered critically endangered in Brazil. Due to the demands of environmental agencies and of conservation programs, there is a need to increase the number of molecular markers available for the genus and specially for S.maximiliani. Therefore, this work aimed to provide a new set of microsatellite markers for S. maximiliani in order to help bird breeders and environmental agencies on fulfilling its demands as well as contributing with extra genetics tools for conservation programs of the Great-billed Seed-finch. Of the 30 markers developed, 25 successfully amplified and 22 were polymorphic. Annealing temperature varied from 52 to 64°C, number of alleles from two to 13 and the medium allele richness was 7.25 and medium expected and observed heterozygosity was, respectively, 0.812 and 0.661. The identity estimate was 8.54x10 -27 and all the other probabilities of non-exclusion (sib-identity, parent pair and first-parent) were <0.001, indicating that this set of microsatellite markers have high genetic variability and high power of individual genetic differentiation for S.maximiliani. Therefore, this work increases the options of molecular markers to be used on inspection for environmental agencies and for conservation programs on analyzing genetic variability and population studies for the Great-billed Seed-finch.</p>

Morphometrics of taxa in the genus Sphenopsis, recorded from adult male (n = 21) and female (n = 15) study skins in the Academy of Natural Sciences of Drexel University, Philadelphia (ANSP) and Delaware Museum of Nature & Science, Greenville (DMNH) collections. Sample sizes and means (± SD) are given for each taxon, within each sex class (female, male), for the following variables: (WG) wing length, (TR) tarsometatarsus length, (TL) tail length, (BL) bill length, and (BW) bill width. All measurements in mm. in Taxonomic status of the Western Hemispingus Sphenopsis ochracea (Thraupidae) and a review of species limits in the genus Sphenopsis P. L. Sclater, 1861

Figure 4 in Home ranges and aspects of the natural history of the Black-masked Finch Coryphaspiza melanotis (Grayı 1840) (Avesı Thraupidae) in central Cerradoı Brazil
Figure 4. Home ranges of ten males of the Black-masked Finch (Coryphaspiza melanotis) in a campo sujo patch at Parque Nacional da Chapada dos Veadeirosı central Brazilı between February and December 2008. Home ranges were delimited using the Minimum Convex Polygon method. Triangles and stars refer to location points of banded and non-banded malesı respectively.

FIGURE 1 in A new genus and species of tanager (Passeriformes, Thraupidae) from the lower Yungas of western Bolivia and southern Peru
FIGURE 1. Phylogenetic analyses of the new species and relatives using separate gene trees (ND2, cyt b, ACO1, and Rag1) and combined analyses (Concatenated, *Beast). Support values (posterior probabilities) are shown at each node. All trees strongly support the placement of the new species in a clade with Eucometis penicillata and Trichothraupis melanops. However, the trees disagree on the relationships of these taxa relative to each other, and none of the trees show strong support for relationships among these three taxa, emphasizing the distinctness of these three species relative to each other.

FIGURE 2. Phylogenetic analyses of the new species and close relatives based on UCE loci. Support values for each node shown for RAxML, SVDQuartets, and ASTRAL. There is strong support for a clade containing the new species, Trichothraupis melanops, and Eucometis penicillata. Within this clade, T. melanops is identified as the closest living relative to the new species. Although strongly supported, the branch connecting the clade comprising the new species and T. melanops is short. Thumbnail illustrations of the birds by DFL.
