HERZOG, A. BENNETT HENNESSEY, MICHAEL KESSLER and VI´CTOR H. GARCI´A-SOLI´Z Summary Since their description in the first half of the 20th century by M. A. Carriker, Bolivian Recurvebill Simoxenops striatus and Yungas Antwren Myrmotherula grisea have been regarded as extremely poorly known endemics of the Bolivian Yungas and adjacent humid foothill forests. They are considered ‘Vulnerable’ under the IUCN criteria of small population, predicted population decline (criterion C2a) and, in the case of Bolivian Recurvebill, small extent of occurrence (criteria B1a+b). Here we summarise the information published to date and present extensive new data on the distribution (including the first records for extreme southeast Peru), natural history, population size and conservation status of both species based on field work in the Bolivian Andes over the past 12 years. Both species primarily inhabit the understorey of primary and mid-aged to older regenerating forest and regularly join mixed-species foraging flocks of insectivorous birds. Bolivian Recurvebill has a strong preference for Guadua bamboo, but it is not an obligate bamboo specialist and persists at often much lower densities in forests without Guadua. Yungas Antwren seems to have a preference for dense, structurally complex under- storey, often with Chusquea bamboo. Both species are distributed much more continuously at altitudes of mostly 600–1,500 m, occupy a greater variety of forest types (wet, humid, semi- deciduous forest) and have a much greater population size than previously thought.

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.

  • New Data Concerning the Distribution, Behaviour, Ecology and Taxonomic Relationships of Minas Gerais Tyrannulet Phylloscartes Roquettei
    Bird Conservation International (2002) 12:241–253. BirdLife International 2002 DOI: 10.1017/S0959270902002150 Printed in the United Kingdom New data concerning the distribution, behaviour, ecology and taxonomic relationships of Minas Gerais Tyrannulet Phylloscartes roquettei MARCOS A. RAPOSO, JUAN MAZAR BARNETT, GUY M. KIRWAN and RICARDO PARRINI Summary We report new observations of the globally threatened Minas Gerais Tyrannulet Phylloscartes roquettei from two areas in the Sa˜o Francisco Valley, Minas Gerais, Brazil, between July 1993 and February 2002. Four pairs, one fledged young and two lone individuals were observed in the course of our fieldwork. It was previously known only from a female taken in the mid-1920s and sight records and tape-recordings in 1977.Our records extend the species’ known range 250 km south and west of the type-locality region. Details of the first-known male specimen are presented, along with novel data concerning its vocalizations and behaviour. We draw attention to the possible relationship of the species to a group of four other Phylloscartes tyrannulets with similarly patterned faces and overall plumage, which exhibit a similar circum-Amazonian distribution pattern to three Phyllomyias tyrannulets. We also take the opportunity to draw more attention to the imperilled conservation status of the dry forests upon which P. roquettei and a host of other threatened and Near-threatened avian taxa depend.

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.

  • Divergence in Nest Placement and Parental Care of Neotropical Foliage‐Gleaners and Treehunters (Furnariidae: Philydorini)

The Neotropical ovenbirds (Furnariidae) are an adaptive radiation of suboscines renowned for the diversity of their nests. Like most altricial insectivores, they generally exhibit biparental care. One tribe, Philydorini, includes 46 species thought to nest in either underground burrows or tree cavities, nest types traditionally treated as equivalent in phylogenetic studies. Their parental care systems are poorly known, but could help illuminate how uniparental care – typically associated with frugivory – can arise in insectivores. We examined the extent to which nest placement, parental care, and associated reproductive traits map onto two major clades of Philydorini identified by genetic hypotheses. We review published literature and present new information from the Atlantic Forest of Argentina, including the first nest descriptions for Ochre-breasted Foliage-gleaners (Anabacerthia lichtensteini) and Sharp-billed Treehunters (Heliobletus contaminatus). In the Automolus-Thripadectes-Clibanornis clade (including Philydor rufum), 134 of 138 reported nests were in underground burrows. In the Syndactyla-Anabacerthia-Anabazenops clade (including Heliobletus, Philydor atricapillus, and Philydor erythrocercum), 44 of 48 nests were in tree cavities.

The morphology of this specimen, collected in 1986 at Pedra Branca, Murici, Alagoas, at 550 m elevation (currently the Murici Ecological Station), suggests its allocation in the genus Cichlocolaptes. The new species differs from P. novaesi by its considerably larger size, heavier body-mass, darker and more uniform forehead and crown, absence of buffy periocular- feathers, and a pale orange-rufous tail that contrasts with the rump and the rest of the dorsal plumage. It also has a flat-crowned appearance and a larger, deeper-based, and generally stouter bill. Behavioral specialization on bromeliads and vocal repertoire also suggest that the new species belongs in the genus Cichlocolaptes. The song of this species is markedly different from that of P. novaesi, and it closely matches that of Cichlocolaptes leucophrus. The new species is endemic to the ‘Pernambuco Center’ of endemism, where it inhabits dense, humid forests in hilly terrain.
