Territory Size and Stability in a Sedentary Neotropical Passerine: Is Resource Partitioning a Necessary Condition?
J. Field Ornithol. 76(4):395±401, 2005 Territory size and stability in a sedentary neotropical passerine: is resource partitioning a necessary condition? Janet V. Gorrell,1 Gary Ritchison,1,3 and Eugene S. Morton2 1 Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 USA 2 Hemlock Hill Field Station, 22318 Teepleville Flats Road, Cambridge Springs, Pennsylvania 16403 USA Received 9 April 2004; accepted 11 April 2005 ABSTRACT. Long-term pair bonds and defense of territories year-round are common among tropical passer- ines. The boundaries of these territories tend to be stable, perhaps re¯ecting the need to defend an area that, regardless of conditions, provides suf®cient food resources. If, however, these stable territories are not, even tem- porarily, suf®ciently large, then intra-pair competition for available food may result, particularly in species with no sexual size dimorphism. With such competition, sex-speci®c differences in foraging behavior may result. Male and female Dusky Antbirds (Cercomacra tyrannina) are not size dimorphic, and pairs jointly defend territories throughout the year. Our objective was to determine if paired Dusky Antbirds exhibited sex-speci®c differences in foraging behavior. Foraging antbirds were observed in central Panama from February±July 2002 to determine if pairs par- titioned food resources. Males and females exhibited no differences in foraging behavior, with individuals of both sexes foraging at similar heights and using the same foraging maneuvers (glean, probe, and sally) and substrates (leaves, rolled leaves, and woody surfaces). These results suggest that Dusky Antbirds do not partition resources and that territory switching, rather than resource partitioning, may be the means by which they gain access to additional food resources. -
Serra Dos Tucanos, Brazil 2017 BIRDS
Field Guides Tour Report Serra dos Tucanos, Brazil 2017 Oct 23, 2017 to Nov 2, 2017 Marcelo Padua For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. We made quite a journey to find this bird! The Three-toed Jacamar is an Atlantic Forest endemic, and we were able to get some super looks at it. Photo by participant Ben Oko. As a tour leader, one of the most common questions I get from participants is, which "tour is my favorite?". Although this is a question with no answer as each tour is different, and I love all the tours I lead, there are certain aspects of a tour that I enjoy more than others, and this tour checks the box for most of them. It starts with the facts that the climate is mild and we usually do not face extreme temperatures, but it also has to do with the abundance of species of birds, many of which are endemic, the comfort of the lodge that offers great food and lovely rooms surrounded by great habitat, the diversity of habitats, and the fact that you get to settle in to a room for long enough to actually enjoy it and unpack your suitcase. This year's tour was a great success. We found most of the targets we set out to find, we enjoyed a good mix of people with great camaraderie, and the weather was kind to us for the most part. So even though I can't choose a favorite tour, I can say with certainty that if I ever had to choose, this would certainly be one of the top contenders. -
Systematic Relationships and Biogeography of the Tracheophone Suboscines (Aves: Passeriformes)
MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 23 (2002) 499–512 www.academicpress.com Systematic relationships and biogeography of the tracheophone suboscines (Aves: Passeriformes) Martin Irestedt,a,b,* Jon Fjeldsaa,c Ulf S. Johansson,a,b and Per G.P. Ericsona a Department of Vertebrate Zoology and Molecular Systematics Laboratory, Swedish Museum of Natural History, P.O. Box 50007, SE-104 05 Stockholm, Sweden b Department of Zoology, University of Stockholm, SE-106 91 Stockholm, Sweden c Zoological Museum, University of Copenhagen, Copenhagen, Denmark Received 29 August 2001; received in revised form 17 January 2002 Abstract Based on their highly specialized ‘‘tracheophone’’ syrinx, the avian families Furnariidae (ovenbirds), Dendrocolaptidae (woodcreepers), Formicariidae (ground antbirds), Thamnophilidae (typical antbirds), Rhinocryptidae (tapaculos), and Conop- ophagidae (gnateaters) have long been recognized to constitute a monophyletic group of suboscine passerines. However, the monophyly of these families have been contested and their interrelationships are poorly understood, and this constrains the pos- sibilities for interpreting adaptive tendencies in this very diverse group. In this study we present a higher-level phylogeny and classification for the tracheophone birds based on phylogenetic analyses of sequence data obtained from 32 ingroup taxa. Both mitochondrial (cytochrome b) and nuclear genes (c-myc, RAG-1, and myoglobin) have been sequenced, and more than 3000 bp were subjected to parsimony and maximum-likelihood analyses. The phylogenetic signals in the mitochondrial and nuclear genes were compared and found to be very similar. The results from the analysis of the combined dataset (all genes, but with transitions at third codon positions in the cytochrome b excluded) partly corroborate previous phylogenetic hypotheses, but several novel arrangements were also suggested. -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

Management and Breeding of Birds of Paradise (Family Paradisaeidae) at the Al Wabra Wildlife Preservation
Management and breeding of Birds of Paradise (family Paradisaeidae) at the Al Wabra Wildlife Preservation. By Richard Switzer Bird Curator, Al Wabra Wildlife Preservation. Presentation for Aviary Congress Singapore, November 2008 Introduction to Birds of Paradise in the Wild Taxonomy The family Paradisaeidae is in the order Passeriformes. In the past decade since the publication of Frith and Beehler (1998), the taxonomy of the family Paradisaeidae has been re-evaluated considerably. Frith and Beehler (1998) listed 42 species in 17 genera. However, the monotypic genus Macgregoria (MacGregor’s Bird of Paradise) has been re-classified in the family Meliphagidae (Honeyeaters). Similarly, 3 species in 2 genera (Cnemophilus and Loboparadisea) – formerly described as the “Wide-gaped Birds of Paradise” – have been re-classified as members of the family Melanocharitidae (Berrypeckers and Longbills) (Cracraft and Feinstein 2000). Additionally the two genera of Sicklebills (Epimachus and Drepanornis) are now considered to be combined as the one genus Epimachus. These changes reduce the total number of genera in the family Paradisaeidae to 13. However, despite the elimination of the 4 species mentioned above, 3 species have been newly described – Berlepsch's Parotia (P. berlepschi), Eastern or Helen’s Parotia (P. helenae) and the Eastern or Growling Riflebird (P. intercedens). The Berlepsch’s Parotia was once considered to be a subspecies of the Carola's Parotia. It was previously known only from four female specimens, discovered in 1985. It was rediscovered during a Conservation International expedition in 2005 and was photographed for the first time. The Eastern Parotia, also known as Helena's Parotia, is sometimes considered to be a subspecies of Lawes's Parotia, but differs in the male’s frontal crest and the female's dorsal plumage colours. -
The Avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, Including Evidence for Long-Term Population Dynamics in Undisturbed Tropical Forest
Ben Freeman & Alexandra M. Class Freeman 30 Bull. B.O.C. 2014 134(1) The avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, including evidence for long-term population dynamics in undisturbed tropical forest Ben Freeman & Alexandra M. Class Freeman Received 27 July 2013 Summary.—We conducted ornithological feld work on Mt. Karimui and in the surrounding lowlands in 2011–12, a site frst surveyed for birds by J. Diamond in 1965. We report range extensions, elevational records and notes on poorly known species observed during our work. We also present a list with elevational distributions for the 271 species recorded in the Karimui region. Finally, we detail possible changes in species abundance and distribution that have occurred between Diamond’s feld work and our own. Most prominently, we suggest that Bicolored Mouse-warbler Crateroscelis nigrorufa might recently have colonised Mt. Karimui’s north-western ridge, a rare example of distributional change in an avian population inhabiting intact tropical forests. The island of New Guinea harbours a diverse, largely endemic avifauna (Beehler et al. 1986). However, ornithological studies are hampered by difculties of access, safety and cost. Consequently, many of its endemic birds remain poorly known, and feld workers continue to describe new taxa (Prat 2000, Beehler et al. 2007), report large range extensions (Freeman et al. 2013) and elucidate natural history (Dumbacher et al. 1992). Of necessity, avifaunal studies are usually based on short-term feld work. As a result, population dynamics are poorly known and limited to comparisons of diferent surveys or diferences noticeable over short timescales (Diamond 1971, Mack & Wright 1996). -
Breeding Biology of Yellow-Browed Antbird Hypocnemis Hypoxantha
Daniel M. Brooks et al. 156 Bull. B.O.C. 2016 136(3) Breeding biology of Yellow-browed Antbird Hypocnemis hypoxantha by Daniel M. Brooks, Pablo Aibar, Pam Bucur, Ron Rossi & Harold F. Greeney Received 17 February 2016 Summary.—We provide novel data concerning the nests, eggs and parental care of Yellow-browed Antbird Hypocnemis hypoxantha based on two nests in eastern Ecuador and Peruvian Amazonia, one of which was video-taped. Both adults participated in incubation, with earliest and latest feeding events at 06.11 h and 17.22 h, respectively. Feeding behaviour is described, with intervals of 1–114 minutes (mean = 38.3 minutes) and tettigoniid cicadas the primary prey. Nestlings frequently produced faecal sacs (interval range = 4–132 minutes, mean = 37.8 minutes) immediately following food delivery, and the sac was always carried from the nest by an adult. Two events involving a parent bird being chased from the nest are described, the first involving a male Fulvous Antshrike Frederickena fulva. Systematics are discussed in light of nest morphology and architecture. Yellow-browed Antbird Hypocnemis hypoxantha is a distinctive Amazonian thamnophilid that comprises two currently recognised subspecies: nominate hypoxantha in western Amazonian lowland and foothill forests from southern Colombia south to central Peru, and H. h. ochraceiventris in south-east Amazonian Brazil (Zimmer & Isler 2003). Generally found below 400 m, the nominate subspecies occasionally ranges as high as 900 m (Zimmer & Isler 2003, Ridgely & Tudor 2009). The species’ reproductive biology is almost completely unknown (Zimmer & Isler 2003). Willis (1988) provided a cursory description of a nest with nestlings from Colombia, but included few details of the nest and no description of the eggs or behaviour. -

Photographic Evidence of Nectar-Feeding by the White-Throated Treecreeper Cormobates Leucophaea
103 AUSTRALIAN FIELD ORNITHOLOGY 2009, 26, 103–104 A White-throated Treecreeper feeding upon the nectar of Umbrella Tree flowers by tongue lapping, near Malanda, north Qld Plate 17 Photo: Clifford B. Frith Photographic Evidence of Nectar-feeding by the White-throated Treecreeper Cormobates leucophaea CLIFFORD B. FRITH P.O. Box 581, Malanda, Queensland 4885 (Email: [email protected]) Summary. An individual of the north-eastern Australian subspecies of the White-throated Treecreeper Cormobates leucophaea minor was closely observed and photographed while clearly feeding upon nectar from the flowers of an Umbrella Tree Schefflera actinophylla. Although the few other records of nectar-feeding by treecreepers (Family Climacteridae) are reviewed, this note presents the first substantiated evidence of nectar-feeding by Australasian treecreepers. The most recent review of the biology of the Family Climacteridae as a whole described treecreepers as taking nectar from flowers at times (Noske 2007). However, few published records of nectar-feeding by any of the six Australian treecreeper species exist. Of the five species of the genus Climacteris, only one (the Brown Treecreeper C. picumnus) is known to occasionally drink nectar from ironbarks such as Mugga Eucalyptus sideroxylon (V. & E. Doerr, cited in Higgins et al. 2001) and from paperbarks (Orenstein 1977). The Black-tailed Treecreeper C. melanura has been observed feeding on the Banksia-like inflorescences of the FRITH: AUSTRALIAN 104 White-throated Treecreeper Eating Nectar FIELD ORNITHOLOGY Bridal Tree Xanthostemon paradoxus, another myrtaceous species (R. Noske pers. comm.). The White-throated Treecreeper Cormobates leucophaea was recently described as ‘Almost wholly insectivorous, mainly bark-dwelling ants; occasionally take some plant material’ (Higgins et al. -

E-mail: [email protected] Abstract We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item. -
