Species highlighted in RED are the ones illustrated with photos in this report. INTRODUCTION Not everyone is fortunate enough to visit Peru; a marvelous country that boasts a huge country bird list, which is second only to Colombia. Unlike our usual set departure, we started out with a daylong extension to Lomas de Lachay first, before starting out on the usual itinerary for the main tour. On this extra day we managed to 1 www.tropicalbirding.com +1-409-515-0514 [email protected] Page Tropical Birding Trip Report PERU: Manu and Machu Picchu Aug-Sept. 2015 find many extra birds like Peruvian Thick-knee, Least Seedsnipe, Peruvian Sheartail, Raimondi’s Yellow- Finch and the localized Cactus Canastero. The first site of the main tour was Huacarpay Lake, near the beautiful Andean city of Cusco (accessed after a short flight from Lima). This gave us a few endemic species like Bearded Mountaineer and Rusty-fronted Canastero; along with other less local species like Many-colored Rush-tyrant, Plumbeous Rail, Puna Teal, Andean Negrito and Puna Ibis. The following day we birded along the road towards Manu where we picked up birds like Peruvian Sierra-Finch, Chestnut-breasted Mountain-Finch, Spot-winged Pigeon, and a beautiful Peruvian endemic in the form of Creamy-crested Spinetail. We also saw Yungas Pygmy-Owl, Black-faced Ibis, Hooded and Scarlet-bellied Mountain- Tanagers, Red-crested Cotinga and the gorgeous Grass-green Tanager.

However, this trip is far from only an Amazonian tour, as it started high in Andes (before making its way down there some days later), above the treeline at Antisana National Park, where we saw Ecuador’s national bird, the Andean Condor, in addition to Ecuadorian Hillstar, 1 www.tropicalbirding.com +1-409-515-9110 [email protected] Page Tropical Birding Trip Report EASTERN ECUADOR October-November 2016 Carunculated Caracara, Black-faced Ibis, Silvery Grebe, and Giant Hummingbird. Staying high up in the paramo grasslands that dominate above the treeline, we visited the Papallacta area, which led us to different high elevation species, like Giant Conebill, Tawny Antpitta, Many-striped Canastero, Blue-mantled Thornbill, Viridian Metaltail, Scarlet-bellied Mountain-Tanager, and Andean Tit-Spinetail. Our lodging area, Guango, was also productive, with White-capped Dipper, Torrent Duck, Buff-breasted Mountain Tanager, Slaty Brushfinch, Chestnut-crowned Antpitta, as well as hummingbirds like, Long-tailed Sylph, Tourmaline Sunangel, Glowing Puffleg, and the odd- looking Sword-billed Hummingbird. Having covered these high elevation, temperate sites, we then drove to another lodge (San Isidro) downslope in subtropical forest lower down.

  • Frugivory by Toucans (Ramphastidae) at Two Altitudes in the Atlantic Forest of Brazil'
    BIOTROPICA 32(4b): 842-850 2000 Frugivory by Toucans (Ramphastidae) at Two Altitudes in the Atlantic Forest of Brazil' Mauro GalettP Plant Phenology and Seed Dispersal Research Group, Departamento de Ecologia, Universidade Estadual Paulista (UNESP), C.P. 199, 13506-900, Rio Claro, Slo Paulo, Brazil Rudi Laps and Marco A. Pizo3 Departamento de Zoologia, UNICAMP, C.P. 6109, 13081-970, Campinas, Slo Paulo, Brazil ABSTRACT Toucans are prominent components of the tropical American avifauna. Although these birds are very conspicuous, there are few ecological studies focusing on them. In this study, the diets of four sympatric toucans (Rampbastos vitellinus, R. dicolorus, Selenidera maculirostris, and Baillonius baillonz) were assessed by recording feeding bouts at two altitudes in the Atlantic Forest of southeast Brazil. Our results show that toucans are predominantly frugivorous birds (96.5% of the 289 feeding bouts were on fruits). In the lowlands (70 m elev.), only fruits (48 species, 27 families) were recorded, while in the highlands (700 m elev.), toucans were observed feeding on fruits (25 species, 22 families), flowers, leaves, and insects. Non-fruit items were recorded only in the highlands, most of them eaten by B. bailloni. Cecropia glaziovii and Euterpe edulis, two abundant plants in the highland and lowland sites, respectively, and firola ole;fera, a plant that produces lipid-rich arillate fruits, were eaten heavily by the toucans. The number of feeding bouts recorded for R. vitellinus in the lowlands was positively correlated with lipid content of the fruits eaten. The diameters of fruits eaten by toucans varied greatly (range = 0.4-25.0 mm).

  • Aniba Rosaeodora Ducke, Lauraceae): an Ecological Approach
    Genetic diversity in rosewood saplings (Aniba rosaeodora ducke, Lauraceae): an ecological approach Ronaldo Pereira SANTOS1, Wilson Roberto SPIRONELLO2, Paulo de Tarso Barbosa SAMPAIO3 ABSTRACT This article takes an ecological approach to the genetic diversity of Rosewood (Aniba rosaeodora Ducke) in a central Amazonian terra firme forest north of Manaus. Planted Rosewood setting, under partial shaded canopy, were assessed in terms of fruiting production, frugivory, and seed dispersal. Using RAPD molecular analysis procedures, the influence of the spatial distribution of adult trees on the genetic diversity (polymorphism) of saplings was assessed with genetic samples from 34 reproductive trees and 60 saplings. The density and distribution patterns the reproductive trees did not modify the sapling’s diversity (1.86%, AMOVA). Two types of adult tree dispersion were identified; i) clumped and ii) more widely dispersed. Polymorphism (77.5%) and gene flow were high between these. Although more sapling genetic variability in areas with a higher density of mature plants was not as high as expected, density did not affect the genetic diversity of samplings, indicating a high incidence of gene flow amongst trees. In planted Rosewood population (surrounded by low disturbed forest), fruiting trees experienced a high level of removal of seeds by toucans (Rhamphastidae), about of 50%. The high gene flow found among native trees suggested that toucans, promoting seed rain at short and long distances from maternal trees, actively contribute to the maintenance of genetic diversity within wild rosewood populations. KEY WORDS: Amazonian tree, RAPD, seed dispersal, gene flow, genetic diversity.

Soon after arriving in Cusco and meeting with our driver we headed out to Huacarpay Lake . Unfortunately our arrival time meant we got there when it was really hot, and activity subsequently low. Although we stuck to it, and slowly but surely, we managed to pick up some good birds. On the lake itself we picked out Puna Teal, Speckled and Cinnamon Teals, Andean (Slate-colored) Coot, White-tufted Grebe, Andean Gull, Yellow-billed Pintail, and even Plumbeous Rails, some of which were seen bizarrely swimming on the lake itself, something I had never seen before.

    THE PHYLOGENETIC RELATIONSHIPS OF THE PICIFORMES (CLASS AVES) SHARONF. SIMPSON1 AND JOEL CRACRAFT2 Department of Anatomy, University of lllinois at the Medical Center, Chicago, Illinois 60680 USA, and Division of Birds, Field Museum of Natural History, Chicago, Illinois 60605 USA ABST•CT.--The phylogenetic relationships of the avian order Piciformes were studied using a cladistic analysis of the skeletal morphology. We hypothesize that the piciforms constitute a monophyletic group on the basis of possessinga unique flexor tendon pattern in the hindlimb, a M. flexor hallucis longus with three heads of origin, zygodactyly, and a well-developed sehnen- halter on the outer (IV) trochlea of the tarsometatarsus.Two major lineagesare defined by osteo- logical characters,one (the Galbulae) consistingof the Galbulidae and Bucconidae,and the other (the Pici) comprising the remaining four families. Within the Pici, two lineagesare discerned:the Ramphastoidea, consistingof the Ramphastidae and the Capitonidae, and the Picoidea, which includes the Picidae and Indicatoridae. The systematic position of the fossil families Zygodactyl- idae and Primobucconidae are interpreted within the framework of the phylogenetic hypothesis for the Recent families. Received 24 September 1980, accepted15 January 1981. DESPITE the efforts of countless investigators over the last 100 yr, corroborated hypothesesabout the phylogenetic relationships of the avian higher taxa remain in short supply. Within this literature it is rare that data from different anatomical systems have been interpreted so as to provide concordant evidence supporting a specific hypothesis of genealogical relationships within a set of these higher taxa. One major reason for this is that workers have traditionally evaluated similarity without regard to the hierarchical level at which these similarities define a set of taxa, i.e.

Through the optics of these living jewels we were able to grasp a more holistic understanding of the intricacies that constitute the ample mosaic of ecosystems, habitats, and niches that make up this wonderland of mega-biodiversity. Our travels took us from the high Andes to the Amazonian foothills, the subtropical and temperate zones, and then back over the eastern cordillera to the interAndean valley and up again over the western cordillera to the elfin and temperate zones, the subtropics, the foothills, and Pacific coastal lowlands along the west slope of the Andes—all within a compact eight- day itinerary. We experienced a lot; we were confronted with some challenges, endured some unseasonal rain and some characteristic fog, and through it all, we reveled in a good dose of wondrous beauty and special moments. Our first morning fired up with a ‘centinel’ Giant Hummingbird, the world’s largest, followed by Sparkling Violetears, a male Black-tailed Trainbearer, and our first Tyrian Metaltail; a soaring male Andean Condor and a nesting Black-chested Buzzard-Eagle Victor Emanuel Nature Tours 2 Northern Ecuador Hummingbird & Tanager Extravaganza R&E, 2019 Giant Hummingbird ©Paul J.
