Jewels of Ecuador: Hummers, Tanagers & Antpittas I
Field Guides Tour Report Jewels of Ecuador: Hummers, Tanagers & Antpittas I 2018 Jan 20, 2018 to Feb 6, 2018 Willy Perez For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Ecuador has so many "jewels", it's hard to know where to begin! And, we saw so many of them, including this gorgeous Green-and-Gold Tanager. Altogether, we saw at least 50 tanager species, and that's only the ones that include "tanager" in their name. Photo by guide Willy Perez. This tour is designed to explore the south and the north, from going very high up in the Andes to descending the foothills in the west and east of the stunning and tiny country of Ecuador. The main gain is to see the jewels, but believe me we saw a lot more than the incredible jewels. We visit completely different habitats and each one contains a unique avifauna. Yanacocha on the west of the Pichincha volcano near Quito was buzzing with hummingbirds. We flew south and landed in the unique Catamayo valley with many Tumbesian species. For a few days we visited the Podocarpus National Park that holds many birds that are restricted to that area. Cajas was the perfect example of a good paramo; it was full of birds and the landscape was breathtaking. Mindo and Silanche in the northwest were busy with many interesting birds, specially the Choco endemics. Papallacta, San Isidro and Guacamayos were all full of surprises on the bird front, perfect to fill up our list of birds and places during these two exciting weeks. -

Although it has a distinct orogenic history from the adjacent ranges of northern South America, Perijá has received little biological research and conservation attention, particularly on the Colombian side. The avifauna of Serranía de Perijá remains understudied and its populations are often not included in bio- geographic studies or taxonomic revisions. Here we present the results of two ornithological expeditions carried out in 2008 and 2009 in along the western (Colombian) slope of this range, from between 1500 to 3100 m. We recorded 182 bird spe- cies in montane forests and paramo habitats. -
Northern Peru: Across the Marañon Canyon, August 2017
Tropical Birding Trip Report Northern Peru: Across the Marañon Canyon, August 2017 Northern Peru: Across the Marañon Canyon August 13-29, 2017 TOUR LEADER: Nick Athanas Report and photos by Nick Athanas; all photos are from the tour Peruvian Plantcutter, the first of many endemics we saw on this tour I’ve been guiding trips to Northern Peru since 2005 and still enjoy coming here every year – the birding seems like it only gets better thanks to new lodges and reserves that have opened over the years. Our 2017 trip was really fun; the trip went really smoothly, we enjoyed superb weather, and had great birding with over 500 species and close to 40 Peruvian endemics. Some favorites included the Peruvian Plantcutter shown above, the truly Marvelous Spatuletail, awesome views of Gray-bellied Comet, six antpittas including an amazingly cooperative Pale-billed Antpitta (it was worth the hike!), two crescentchests, and three inca-finches. New feeding stations in the area helped us get some superb sightings of normally tough species including Rusty-tinged Antpitta, Rufous-breasted Wood-Quail, tinamous, and Ecuadorian Piedtail. That’s not to say everything was easy! Several key species only revealed themselves after a significant amount www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Northern Peru: Across the Marañon Canyon, August 2017 of effort at the “eleventh hour”, chief among these being Long-whiskered Owlet, Little Inca-Finch, Marañon Crescentchest, and Tumbes Hummingbird; persistence is often the best antidote to the occasional intrusion of poor luck... A few nice mammal sightings added excitement to our trip, headlined by two very rare monkeys at Abra Patricia: Yellow-tailed Woolly Monkey and Peruvian Night Monkey. -
Santa Marta Escape 2019
Field Guides Tour Report Colombia: Santa Marta Escape 2019 Feb 18, 2019 to Feb 26, 2019 Cory Gregory, Tom Johnson, and Diana Balcázar For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. One of the absolute favorites on this trip is the vivid but skulky Vermilion Cardinal. Found only in Venezuela and a sliver of Colombia, this is a specialty of the region. Photo by guide Tom Johnson. With a pleasant climate, an easy flight from Miami, a wealth of endemic birds, and breathtaking scenery, the Santa Marta Escape trip had a perfect mix of distractions for the winter that we were all escaping from! Right off the bat, in the city of Barranquilla, we found a quiet university street that was alive with Chestnut-winged Chachalacas, a species only found in Colombia! Farther along, on Isla Salamanca, we all braved the foot-ferry and were rewarded with an amazing study of Sapphire-throated/Sapphire- bellied Hummingbirds. Even when some of the locals went on strike and closed the road for a little bit, we found a way to see amazing birds and we ended up scoring Buff-breasted Wren, White-winged Becard, and a quick Lance-tailed Manakin at a new spot. The Guajira Peninsula, extending farther north than any other point of South America, was our destination for a day of birding around Camarones. The dry and scrubby habitats yielded a variety of local specialties like Tocuyo Sparrow, Vermilion Cardinal, Orinocan Saltator, Buffy Hummingbird, Bare- eyed Pigeon, White-whiskered Spinetail, Double-striped Thick-knee, and several others. -
The Avifauna of Cajas National Park and Mazán Reserve, Southern Ecuador, with Notes on New Records Pedro X
Cotinga 37 The avifauna of Cajas National Park and Mazán Reserve, southern Ecuador, with notes on new records Pedro X. Astudillo, Boris A. Tinoco and David C. Siddons Received 1 June 2013; final revision accepted 23 February 2014 Cotinga 37 (2015): OL 1–11 published online 10 March 2015 El Parque Nacional Cajas es un área de interés para científicos y aficionados de las aves debido principalmente a su muestra representativa de los ecosistemas andinos. Los Andes presentan altos niveles de diversidad y a la vez fuertes presiones ocasionadas por actividades humanas. Así, los parques nacionales son herramientas importantes para la conservación de la biodiversidad. Dentro de este marco, es importante contar con listados completos de las especies que ocupan estos territorios. El presente trabajo recoge las principales observaciones ornitológicas en el Parque Nacional Cajas, prov. Azuay, Ecuador, desde 1980. Adicionalmente, se incluye breves descripciones de especies no reportadas previamente en el área, importantes para la conservación y para la región. Las aves son buenos indicadores de calidad de hábitat y un importante componente en actividades turísticas. The tropical Andes harbour the largest number CNP4.

THE SANTA MARTA ENDEMICS SPECIAL AND BOGOTA EXTENSION TRIP REPORT Main trip Nov 5 – 13 /2010 Extension April 13- 19 /2010 Tour Leader: Lelis Navarrete Hostess: Mercedes Rivadeneira PARTICIPANTS: Bob Balestri, Marcia Balestri, Miriam Bauman, David Gascoigne, Jay Lamb, Judy Lamb, Alan Miles, David L. Pearson. Blue-naped Chlorophonia by Lelis Navarrete A birding and nature trip to Colombia is a dream come true for many people. Many of the participants on this trip had already visited many other countries in South America. And only now has the safety in Colombia improved to the point where traveling in Colombia is as safe as traveling through any other Latin-American country; many of our friends and customers are joining us in the wonderful experience of seeing the culture and birds in the country with the biggest number of bird species in the world. It was a successful and uneventful trip where we manage to find and see 36 of the Colombian endemic bird species. The following lines summarize our unforgettable experiences, read on and enjoy.... Nov 4th. Most of the participants arrived in different flights but most of us were able to introduce each other over an early dinner. Knowing we will have an early start the next day we decided to go to bed early. Unfortunately there was a group celebrating Halloween with a noise party full of laud music. It was the time to use earplugs for otherwise we could have had very little rest. Nov 5th. The morning started with a torrential rain but we headed towards Parque Via Isla Salamanca in the way to Santa Marta city. -

Field Guides Tour Report Colombia: Cali Escape 2017 Nov 18, 2017 to Nov 27, 2017 Richard Webster & Daniel Uribe For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. We expect to see Gold-ringed Tanager. We don't expect to see it in the road in front of us! One of the many wonderful birds from our visit to Cerro Montezuma. Photo by participant Steve Parrish. It was an active birding adventure to some great Colombian birding spots! A new itinerary--mostly going to spots on an older, longer itinerary--it worked very well and provided great variety in a time period that fits folks’ time budgets. We started in the Western Andes above Cali with some good birding highlighted by our visit to the feeders at Finca Alejandria, where we luxuriated in the constant action at the many hummingbird feeders and in the great variety at the loaded banana feeders. Multicolored Tanager was the best of the best, with much pleasure from Red-headed Barbets, Southern Emerald- and Crimson-rumped toucanets, Colombian Chachalacas, super-saturated Blue- winged Mountain-Tanagers and Golden, Golden-naped, and Saffron-crowned tanagers, Black-winged Saltator, White-naped Brushfinches, Booted Racket-tails, Fawn-breasted Brilliants, and Brown Violetears. A perched young Ornate Hawk-Eagle was a bonus. An afternoon and the following morning around Buga took us to Laguna de Sonso and El Vinculo. These varied areas of marsh and woodland featured the endemic Apical Flycatcher and a nice variety of landbirds that included Dwarf Cuckoo, Spectacled Parrotlet, Bar-crested Antshrike, Jet Antbird, Cinereous Becard, and Slate-headed Tody-Tyrant. -
