Yet, it was still too early to experience the real explosion of bird song, which usually happens after dawn. Then, after 05:30 AM, the chorus started when a vocal Great Kiskadee broke the morning silence, followed by the scratchy notes of two Hoffmann´s Woodpeckers, a nesting pair of Inca Doves, the ascending and monotonous song of the Yellow-bellied Elaenia, and the cacophony of an (apparently!) engaged pair of Rufous-naped Wrens. This was indeed a warm welcome to magical Costa Rica! To complement the first morning of birding, two boreal migrants, Baltimore Orioles and a Tennessee Warbler, joined the bird feast just outside the hotel area. Broad-billed Motmot . Photo: D. Ascanio © Victor Emanuel Nature Tours 2 The Best of Costa Rica, 2019 After breakfast, we drove towards the volcanic ring of Costa Rica. Circling the slope of Poas volcano, we eventually reached the inspiring Bosque de Paz. With its hummingbird feeders and trails transecting a beautiful moss-covered forest, this lodge offered us the opportunity to see one of Costa Rica´s most difficult-to-see Grallaridae, the Scaled Antpitta.

  • Peru: from the Cusco Andes to the Manu
    The critically endangered Royal Cinclodes - our bird-of-the-trip (all photos taken on this tour by Pete Morris) PERU: FROM THE CUSCO ANDES TO THE MANU 26 JULY – 12 AUGUST 2017 LEADERS: PETE MORRIS and GUNNAR ENGBLOM This brand new itinerary really was a tour of two halves! For the frst half of the tour we really were up on the roof of the world, exploring the Andes that surround Cusco up to altitudes in excess of 4000m. Cold clear air and fantastic snow-clad peaks were the order of the day here as we went about our task of seeking out a number of scarce, localized and seldom-seen endemics. For the second half of the tour we plunged down off of the mountains and took the long snaking Manu Road, right down to the Amazon basin. Here we traded the mountainous peaks for vistas of forest that stretched as far as the eye could see in one of the planet’s most diverse regions. Here, the temperatures rose in line with our ever growing list of sightings! In all, we amassed a grand total of 537 species of birds, including 36 which provided audio encounters only! As we all know though, it’s not necessarily the shear number of species that counts, but more the quality, and we found many high quality species. New species for the Birdquest life list included Apurimac Spinetail, Vilcabamba Thistletail, Am- pay (still to be described) and Vilcabamba Tapaculos and Apurimac Brushfnch, whilst other montane goodies included the stunning Bearded Mountaineer, White-tufted Sunbeam the critically endangered Royal Cinclodes, 1 BirdQuest Tour Report: Peru: From the Cusco Andes to The Manu 2017 www.birdquest-tours.com These wonderful Blue-headed Macaws were a brilliant highlight near to Atalaya.

Here, we 32 test in the riverside wren (Cantorchilus semibadius), a neotropical duetting species that 33 produces highly coordinated duet songs, whether males and females show similar 34 responses to playback.

(Pete Morris) COLOMBIA: FROM THE CHOCO TO AMAZONIA 9/12/15 JANUARY – 5/11 FEBRUARY 2016 LEADER: PETE MORRIS Well, this was the first time that we had run our revised Colombia With a Difference tour – now aptly-named Colombia: From the Choco to Amazonia. Complete with all the trimmings, which included pre-tour visits to San Andres and Providencia, the Sooty-capped Puffbird Extension, and the post tour Mitu Extension, we managed to amass in excess of 850 species. Travelling to the Caribbean, the Pacific Coast, the High Andes and the Amazon all in one trip really was quite an experience, and the variety and diversity of species recorded, at times, almost overwhelming! Picking out just a few highlights from such a long list is difficult, but here’s just an 1 BirdQuest Tour Report:Colombia: From the Choco to Amazonia www.birdquest-tours.com The exquisite Golden-bellied Starfrontlet, one of a number of stunning hummers and our bird-of-the-trip!

  • Breeding Ecology and Nest-Site Selection of Song Wrens in Central Panama
    The Auk 117(2):345-354, 2000 BREEDING ECOLOGY AND NEST-SITE SELECTION OF SONG WRENS IN CENTRAL PANAMA TARA R. ROBINSON/-^-^ W. DOUGLAS ROBINSON/'^-^ AND E. CEINWEN EDWARDS^ ^Department of Ecology, Ethology, and Evolution, University of Illinois, Champaign, Illinois 61820, USA; and 'Smithsonian Tropical Research Institute, P.O. Box 2072, Balboa, Republic of Panama ABSTRACT.•We describe nest-site selection and report measures of breeding productivity from a population of Song Wrens {Cyphorhinus phaeocephalus) in central Panama. We studied 31 pairs from 1995 to 1998 and collected data on nest prédation from 1996 to 1998. Song Wrens are year-round residents that build breeding nests for reproduction and dormitory nests for roosting. Twenty-five of 50 Song Wren breeding nests produced fledglings (daily nest survival rate = 0.968). Song Wrens usually (78%) placed their breeding nests in ant- defended acacias {Acacia melanoceras). However, nests placed in acacias did not experience lower rates of nest prédation than nests placed in sites not defended by ants. The population- wide breeding season was seven months long, but individual pairs often bred within a span of only 2.5 months. Modal clutch size was two (n = 42), but the frequency of three-egg clutch- es was high (>27%). Pairs that lost eggs or chicks renested more quickly than pairs that fledged young and attempted a second brood. Observed annual production of young was 1.4 fledglings per pair. Compared with other wrens. Song Wrens had a much longer breeding season and longer intervals between broods. The annual productivity of Song Wrens was the lowest recorded for any wren, which may have been due to smaller clutch sizes, long inter- vals between broods, and the correspondingly low number of nesting attempts per pair per year.

(u.) annae, male, Cock-of-the-rock Lodge, 30 Neotropical Birding 22 Cuzco, Peru, August 2017 (Bradley Hacker). This series focuses on recent taxonomic proposals – descriptions of new taxa, splits, lumps or reorganisations – that are likely to be of greatest interest to birders. This latest instalment includes: new species of sabrewing, parrot (maybe), tapaculo, and yellow finch (perhaps); proposed splits in Booted Racket-tail, Russet Antshrike, White-backed Fire-eye (split city!), Collared Crescentchest, Olive-backed Foliage-gleaner, Musician Wren, Spotted Nightingale-Thrush, Yellowish and Short-billed Pipits, Black-and- rufous Warbling Finch, Pectoral and Saffron-billed Sparrows, and Unicolored Blackbird; a reassessment of an earlier proposed split in Black-billed Thrush; the (gasp!) possibility of the lump of South Georgia Pipit; and re- evaluations of two birds each known only from a single specimen.

Freeman & Harold F. Greeney Yanayacu Biological Station and Center for Creative Studies c/o Foch 721 y Amazonas, Quito, Ecuador. e-mail: [email protected] ABSTRACT We provide the first description of the nest, eggs and nestlings of Sharpe’s Wren ( Cinnycerthia olivascens ) from northeastern Ecuador, and we document the occurrence of cooperative breeding in this species. Cinnycerthia olivascens builds large enclosed ball nests with a downward-projecting tubular entrance. The eggs are off-white with sparse reddish-brown speckling. We show that at least three adults may participate in nest-building and probably contribute to nestling provisioning. Our video observations document fledgling and show that the nestlings’ diet consisted of small invertebrates. Key words: Cinnycerthia olivascens , cooperative breeding, natural history, Sharpe’s Wren . RESUMEN Describimos por la primera vez el nido, los huevos y los pichones del Soterrey Caferrojizo (Cinnycerthia olivascens ) del noreste de Ecuador, y documentamos la existencia de cría cooperativa en esta especie. Cinnycerthia olivascens construye un nido encerrado, en forma de bola, con una entrada tubular. Los huevos son blancuzcos con manchas de color canela. Por lo menos tres adultos construyen el nido, y probablemente contribuyen al cuidado de los pichones. Por medio de grabaciones de video se documentó la salida de los pichones del nido y se observó que su dieta de los pichones consiste de invertebrados pequeños.
