Foraging Behavior of Plain-Mantled Tit-Spinetail (Leptasthenura Aegithaloides) in Semiarid Matorral, North-Central Chile
ORNITOLOGIA NEOTROPICAL 22: 247–256, 2011 © The Neotropical Ornithological Society FORAGING BEHAVIOR OF PLAIN-MANTLED TIT-SPINETAIL (LEPTASTHENURA AEGITHALOIDES) IN SEMIARID MATORRAL, NORTH-CENTRAL CHILE Andrew Engilis Jr. & Douglas A. Kelt Department of Wildlife, Fish, and Conservation Biology - University of California, One Shields Avenue, Davis, CA 95616, USA. E-mail: [email protected] Resumen. – Comportamiento de forrajeo del tijeral (Leptasthenura aegithaloides) en matorral semiárido, centro-norte de Chile. – Hemos estudiado el comportamiento de forrajeo del tijeral (Leptas- thenura aegithaloides) en el matorral del centro-norte de Chile. Se trata de una especie de la familia Fur- nariidae que es insectívora recolectora desde perchas. Frecuenta los arbustos más dominantes y busca presas y alimentos principalmente en el follaje, grupos de flores, pequeñas ramas y masas de líquenes. Los arbustos preferidos incluyen a Porlieria y Baccharis. Se alimentan desde alturas cercanas al suelo hasta arbustos superiores a dos metros de altura. Se los encuentra más frecuentemente en parejas o en grupos pequeños, posiblemente familias, de tres a cinco aves. Las densidades promedio en el matorral (1,49 - 1,69 aves por hectárea) son mayores que las reportadas para otros lugares. Los tijerales en el matorral forman grupos de especies mixtas con facilidad, especialmente en el invierno Austral. Su estrategia de forrajeo y su comportamiento son similares a las del Mito sastrecillo de América del Norte (Psaltriparus minimus) y del Mito común (Aegithalos caudatus), ambos de la familia Aegithalidae, sugir- iendo estrategias ecológicas convergentes en ambientes estructuralmente similares. Abstract. – We studied foraging behavior of Plain-mantled Tit-spinetail (Leptasthenura aegithaloides) in matorral (scrubland) habitat of north-central Chile. -

With the vehicles already pre-hired, we were soon heading south along the US101 towards Monterey. As we travelled along the highway and away from the suburbs of San Francisco, passing through Silicon Valley, we had excellent views of the mountains and hills of the Diablo Range to our left. In the afternoon sunshine, the dry grassy scrub known as chaparral was golden-coloured. Because of the later flight and it getting dark, we took a more direct route to Carmel Valley, via Salinas and over Laureless Grade into the valley. We arrived at our accommodation in Carmel Valley Lodge about 9pm local time where, after accessing our rooms, some partook in the cold deli supper left for us, before retiring to bed after a long day. Day 2 Sunday 28th August Monterey Bay and Carmel Valley Morning came too soon for some and not early enough for others with body clocks all scrambled, however a fine breakfast of scrambled eggs, toast and cereals was very welcome. -
Western Washington State Custom Trip Report
UNITED STATES OF AMERICA: WESTERN WASHINGTON STATE CUSTOM TRIP REPORT 8 – 15 AUGUST 2019 By Christian Hagenlocher Band-tailed Pigeon was one of the many species we found on this trip. www.birdingecotours.com [email protected] 2 | TRIP REPORT Western Washington State August 2019 Overview This custom trip combined some of the classic destinations in western Washington, covering a variety of habitats from pelagic birding to the alpine slopes of Mount Rainier. We drove over 1,000 miles of roads, ranging from highways to logging roads, in search of a wide variety of species. Our total list contained 147 species (and one additional species heard only). The itinerary was adapted from our sister company Bird Treks’ Washington Tour. With only one client signed up we tailored the itinerary to meet her needs and requests for target birds. This itinerary centered around a pelagic day trip with Westport Seabirds, followed by visiting some key birding locations for owls and grouse in addition to secondary western target birds which would be lifers for the client. Detailed Report Day 1, August 8th 2029. Seattle to Westport via Nisqually National Wildlife Refuge We began with a mid-morning pickup from the client’s hotel near SeaTac, from where we jumped into Thursday morning traffic, heading toward downtown Seattle. We chose to begin the trip with a ferry boat ride from Seattle to Bremerton. After boarding the boat we walked to the observation deck with our binoculars and had great looks at the classic “Olympic Gull”— a Western Gull x Glaucous-winged Gull hybrid complex that inhabits Puget Sound. -
11 – 26 April 2017
Golden-cheeked Warbler in Ashe Juniper, South Llano River State Park (Mike Watson). TEXAS 11 – 26 APRIL 2017 LEADER: MIKE WATSON. Our latest tour of the Lone Star State produced a very respectable total of 306 bird species, including 65 Birdquest ‘diamond’ species (regional endemics or specialities) and 37 species of American wood warblers! Amongst these were some of the USA’s most sought-after birds. Our journey started down in the palms and subtropical woodland of the Lower Rio Grande Valley with a quartet of Northeast Mexican regional endem- ics - Red-crowned Parrot, Green Parakeet, Black-crested Titmouse and Long-billed Thrasher. Other birds of a southerly distribution, whose ranges just cross the Mexican border into the USA included Plain Chacha- laca, Least Grebe, Zone-tailed, White-tailed and Grey Hawks, Red-billed Pigeon, White-tipped Dove, Elf Owl, Pauraque, Buff-bellied Hummingbird, Green and Ringed Kingfshers, Golden-fronted Woodpecker, Aplomado Falcon (reintroduced here), Northern Beardless Tyrannulet, Tropical and Couch’s Kingbirds, Brown-crested Flycatcher, Green Jay, Clay-coloured Thrush, Altamira and Audubon’s Orioles and White-collared Seedeater. On the Upper Texas Coast we were lucky to experience a ‘fall out’ of Trans-Caribbean migrant passerines right at the end of our stay at High Island, one of world birding’s true Meccas, where a sparkling line-up of 20 species of wood warblers included two Ceruleans. The marshes and shores around Galveston Bay held Fulvous Whis- tling Duck, King Rail, Piping Plover, Hudsonian Godwit and Upland Sandpiper. We even managed a ‘write-in’ to this very long-established tour here in the form of a Long-tailed Duck. -

Having eased slowly into the trip, we awoke bleary eyed for a very early morning drive the next day to Finca Los Andes – a private coffee farm hosting some pristine cloud forest. A rather bumpy ride up the side of Volcan Atitlan had everyone wide awake by the time we arrived though. While birding started a little quietly, we did get good scoped views of Blue-crowned Chlorophonia, before having excellent views of two of the major highlights of the day, lekking Emerald-chinned Hummingbirds and a small flock of Cabanis’s (Azure-rumped) Tanagers feeding quietly above us. The mid-morning thermals offered up Black Hawk-Eagle, Common Black Hawk and a flock of Violet-green Swallows. After a successful morning in the cloud forests, we descended past perched Bat Falcons to bird the gardens around the main farmstead, adding Blue-tailed, Berylline and Ruby-throated Hummingbirds, Bushy-crested Jays, skulking MacGillivray’s Warbler and a plethora of Orioles including Spot-breasted, Orchard, Baltimore and Altamira. Following lunch, we drove around the base of Volcan Atitlan to Finca Los Tarrales for a two-night stay. -

Southern Mexico
The stunning Horned Guan is without a doubt one of the best birds in the world (Nigel Redman) SOUTHERN MEXICO 26 FEBRUARY / 3 MARCH – 19 MARCH 2017 LEADERS: MARK VAN BEIRS and NIGEL REDMAN On our 11th Southern Mexico tour we assembled a mouth-watering list of endemics and specialities on our wanderings through the varied habitats of this scenic, very birdy and sadly much maligned country. Our travels took us first to the pristine evergreen and cloud forests of the magnificent El Triunfo Reserve where the fabled Horned Guan showed so very well, next to marvels like Highland Guan, White-faced Quail-Dove, Fulvous Owl, Blue-throated Motmot, Sparkling-tailed Woodstar, Wine-throated and Emerald-chinned Hummingbirds, Resplendent Quetzal, Black-throated Jay, Spotted and Russet Nightingale Thrushes and Prevost’s and White-eared Ground Sparrows. The main tour took us from the forests and scrubby hills of the deep southern state of Chiapas, through the coastal habitats, pine-oak forests and dry inter-montane valleys of Oaxaca, via the limestone hills of Veracruz to the high altitude pine forests and marshes near Mexico City. The Birds of the Trip were without a doubt the striking Horned Guan that performed so very, very well at El 1 BirdQuest Tour Report: Southern Mexico www.birdquest-tours.com Triunfo and the uniquely coloured Pink-headed Warbler that stole our hearts near San Cristobal. The cracking Bumblebee Hummingbird, the magnificent Fulvous Owl, the exquisite Orange-breasted and Rose- bellied Buntings, the rare Golden-cheeked and the exquisite Red Warblers and the unique Ocellated Thrasher were also very much appreciated. -
Colorado 4Th to 14Th April 2019 (11 Days) Trip Report
USA Colorado 4th to 14th April 2019 (11 days) Trip Report Sage Grouse by Stephan Lorenz Trip report compiled by Tour Leader: Stephan Lorenz Trip Report – RBL USA – Colorado 2019 2 Tour Summary This was one of the most successful Colorado Tours to date, an incredible 2,600-mile adventure that criss-crossed one of the most beautiful states. The tour was filled to the brim with rare birds, especially grouse and quail, of course, many mammals, nearly thirty species, and unforgettable scenery. We visited the prairies of Kansas, drove into the High Rockies, explored gorges and canyons, headed to the high Sagebrush steppe of western Colorado, and even included a short side excursion to the Colorado-Utah border to nab a few specialties. Overall, the tour was a complete success with all native grouse and quail species seen extremely well, some down to a few metres as they performed their distinctive booming and dances. The photographic opportunities were outstanding, and even the endangered and declining Gunnison Grouse was seen well this year. It was also the only tour in recent memory that found all possible winter finches, including the nomadic Evening Grosbeak, unpredictable Woodhouse’s Scrub Jay by Stephan Lorenz Pine Grosbeak, Red Crossbill, Cassin's Finch, and of course the star attractions, all three species of rosy finches. Other Rocky Mountain specialties included American Three-toed and Lewis's Woodpeckers, Williamson's Sapsucker, the tricky Pinyon Jay, newly split Woodhouse's Scrub Jay, and more. The vast grasslands of the eastern plains offered a pair of difficult Mountain Plovers and the duo of longspurs with both McCown's and Chestnut-collared seen very well.
