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.

DOI: http://dx.doi.org/10.15446/abc. v25n1.77442 ABSTRACT Several scientific reasons support continuing bird collection in Colombia, a megadiverse country with modest science financing. Despite the recognized value of biological collections for the rigorous study of biodiversity, there is scarce information on the monetary costs of specimens. We present results for three expeditions conducted in Santander (municipalities of Cimitarra, El Carmen de Chucurí, and Santa Barbara), Colombia, during 2018 to collect bird voucher specimens, quantifying the costs of obtaining such material. After a sampling effort of 1290 mist net hours and occasional collection using an airgun, we collected 300 bird voucher specimens, representing 117 species from 30 families.

  • Diagnosis and Observations of a Hybrid Hummingbird (Metallura Tyrianthina X Aglaiocercus Kingi) in the Eastern Andes of Colombia F
    Rev. Acad. Colomb. Cienc. Ex. Fis. Nat. 39(153):481-490, octubre-diciembre de 2015 Hybrid hummingbird at Rogitama, Boyacá doi: http://dx.doi.org/10.18257/raccefyn.260 Ciencias naturales Diagnosis and observations of a hybrid hummingbird (Metallura tyrianthina x Aglaiocercus kingi) in the Eastern Andes of Colombia F. Gary Stiles*, José Oswaldo Cortés-Herrera Instituto de Ciencias Naturales, Universidad Nacional de Colombia, Bogotá, Colombia Abstract An unusual, strikingly colored male hummingbird present for several months in the Rogitama Biodiversity Reserve in Boyacá, Colombia created considerable media attention. It was initially suggested that the bird might represent the rediscovery of the Bogotá Sunangel, Heliangelus zusii. However, a later study of its DNA identified H. zusii as a member of a clade that includes Aglaiocercus and Taphrolesbia. Given the many differences in plumage from the Rogitama hummingbird, this hypothesis was rejected. Three hypotheses regarding its identity were examined in detail: it could represent an unusually colored male of Aglaiocercus kingi, a hybrid between two local species, or an undescribed species. We observed this bird’s foraging and interactions with other hummingbirds, recorded its song and captured it to describe in detail its plumage and take morphological measurements, after which it was released. We rejected all hypotheses except that of a hybrid, and concluded that A. kingi and Metallura tyrianthina were its probable parents. In contrast to its plumage and morphometrics, its song was unlike those of its putative parents, possibly representing a transgressive character. The same may be true of the bluish coloration (termed “hybrid bluing”) that characterized several hybrids between green-backed parental species, including the Rogitama hummingbird.

Since its foundation in 2001, the Land Acquisition Fund has enabled and facilitated the acquisition of over 40,000 hectares of nature, thereby creating a foundation for species to survive and thrive. For more than 100 NGOs, the fund proved to be crucial in pursuing their conservation objectives. The support provided allowed these NGOs to grow, both institutionally and in hectares under sustainable management.

  • South East Brazil, 18Th – 27Th January 2018, by Martin Wootton
    South East Brazil 18th – 27th January 2018 Grey-winged Cotinga (AF), Pico da Caledonia – rare, range-restricted, difficult to see, Bird of the Trip Introduction This report covers a short trip to South East Brazil staying at Itororó Eco-lodge managed & owned by Rainer Dungs. Andy Foster of Serra Dos Tucanos guided the small group. Itinerary Thursday 18th January • Nightmare of a travel day with the flight leaving Manchester 30 mins late and then only able to land in Amsterdam at the second attempt due to high winds. Quick sprint (stagger!) across Schiphol airport to get onto the Rio flight which then parked on the tarmac for 2 hours due to the winds. Another roller-coaster ride across a turbulent North Atlantic and we finally arrived in Rio De Janeiro two hours late. Eventually managed to get the free shuttle to the Linx Hotel adjacent to airport Friday 19th January • Collected from the Linx by our very punctual driver (this was to be a theme) and 2.5hour transfer to Itororo Lodge through surprisingly light traffic. Birded the White Trail in the afternoon. Saturday 20th January • All day in Duas Barras & Sumidouro area. Luggage arrived. Sunday 21st January • All day at REGUA (Reserva Ecologica de Guapiacu) – wetlands and surrounding lowland forest. Andy was ill so guided by the very capable REGUA guide Adelei. Short visit late pm to Waldanoor Trail for Frilled Coquette & then return to lodge Monday 22nd January • All day around lodge – Blue Trail (am) & White Trail (pm) Tuesday 23rd January • Early start (& finish) at Pico da Caledonia.
