Long-Term Changes in the Bird Community of Palenque, Chiapas, in Response to Rainforest Loss
Biodivers Conserv (2010) 19:21–36 DOI 10.1007/s10531-009-9698-z ORIGINAL PAPER Long-term changes in the bird community of Palenque, Chiapas, in response to rainforest loss Michael A. Patten Æ He´ctor Go´mez de Silva Æ Brenda D. Smith-Patten Received: 18 March 2008 / Accepted: 22 July 2009 / Published online: 6 August 2009 Ó Springer Science+Business Media B.V. 2009 Abstract With increased human populations and subsequent pressure to develop or farm land, the rate of fragmentation of tropical rainforests has accelerated in the past several decades. How native organisms respond to such fragmentation has been the subject of intense study in temperate ecosystems and at several tropical sites in Central and South America, but there has been little study of this phenomenon in Mexico, the country bridging the Neotropics and temperate North America. A reason for this neglect is an apparent lack of long-term data; however, such data can be obtained from ‘‘non-tradi- tional’’ sources, such as birders and tour leaders. We make innovative use of such data, combining them with more traditional data (e.g., museum specimens) to create a record of occurrence for Palenque, Mexico, from 1900 to 2009, including a near-continuous pres- ence–absence record since 1970. We analyzed these data using logistic regression and, importantly, recent statistical advances expressly for sighting records. As recently as the 1960s Palenque’s forest was contiguous with that of Selva Lacandona to the east, but the protected area surrounding the famous ruins is now a forested island. As a result, various species formerly known from the site have disappeared, including species both large (Crax rubra, Penelope purpurascens, and Ara macao) and small (Notharchus hyperrhynchos, Malacoptila panamensis, Microrhopias quixensis, and Pachyramphus cinnamomeus). -
Territory Size and Stability in a Sedentary Neotropical Passerine: Is Resource Partitioning a Necessary Condition?
J. Field Ornithol. 76(4):395±401, 2005 Territory size and stability in a sedentary neotropical passerine: is resource partitioning a necessary condition? Janet V. Gorrell,1 Gary Ritchison,1,3 and Eugene S. Morton2 1 Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 USA 2 Hemlock Hill Field Station, 22318 Teepleville Flats Road, Cambridge Springs, Pennsylvania 16403 USA Received 9 April 2004; accepted 11 April 2005 ABSTRACT. Long-term pair bonds and defense of territories year-round are common among tropical passer- ines. The boundaries of these territories tend to be stable, perhaps re¯ecting the need to defend an area that, regardless of conditions, provides suf®cient food resources. If, however, these stable territories are not, even tem- porarily, suf®ciently large, then intra-pair competition for available food may result, particularly in species with no sexual size dimorphism. With such competition, sex-speci®c differences in foraging behavior may result. Male and female Dusky Antbirds (Cercomacra tyrannina) are not size dimorphic, and pairs jointly defend territories throughout the year. Our objective was to determine if paired Dusky Antbirds exhibited sex-speci®c differences in foraging behavior. Foraging antbirds were observed in central Panama from February±July 2002 to determine if pairs par- titioned food resources. Males and females exhibited no differences in foraging behavior, with individuals of both sexes foraging at similar heights and using the same foraging maneuvers (glean, probe, and sally) and substrates (leaves, rolled leaves, and woody surfaces). These results suggest that Dusky Antbirds do not partition resources and that territory switching, rather than resource partitioning, may be the means by which they gain access to additional food resources. -

Breeding Biology of Yellow-Browed Antbird Hypocnemis Hypoxantha
Daniel M. Brooks et al. 156 Bull. B.O.C. 2016 136(3) Breeding biology of Yellow-browed Antbird Hypocnemis hypoxantha by Daniel M. Brooks, Pablo Aibar, Pam Bucur, Ron Rossi & Harold F. Greeney Received 17 February 2016 Summary.—We provide novel data concerning the nests, eggs and parental care of Yellow-browed Antbird Hypocnemis hypoxantha based on two nests in eastern Ecuador and Peruvian Amazonia, one of which was video-taped. Both adults participated in incubation, with earliest and latest feeding events at 06.11 h and 17.22 h, respectively. Feeding behaviour is described, with intervals of 1–114 minutes (mean = 38.3 minutes) and tettigoniid cicadas the primary prey. Nestlings frequently produced faecal sacs (interval range = 4–132 minutes, mean = 37.8 minutes) immediately following food delivery, and the sac was always carried from the nest by an adult. Two events involving a parent bird being chased from the nest are described, the first involving a male Fulvous Antshrike Frederickena fulva. Systematics are discussed in light of nest morphology and architecture. Yellow-browed Antbird Hypocnemis hypoxantha is a distinctive Amazonian thamnophilid that comprises two currently recognised subspecies: nominate hypoxantha in western Amazonian lowland and foothill forests from southern Colombia south to central Peru, and H. h. ochraceiventris in south-east Amazonian Brazil (Zimmer & Isler 2003). Generally found below 400 m, the nominate subspecies occasionally ranges as high as 900 m (Zimmer & Isler 2003, Ridgely & Tudor 2009). The species’ reproductive biology is almost completely unknown (Zimmer & Isler 2003). Willis (1988) provided a cursory description of a nest with nestlings from Colombia, but included few details of the nest and no description of the eggs or behaviour. -

COLOMBIA 2019 Ned Brinkley Departments of Vaupés, Chocó, Risaralda, Santander, Antioquia, Magdalena, Tolima, Atlántico, La Guajira, Boyacá, Distrito Capital de Bogotá, Caldas These comments are provided to help independent birders traveling in Colombia, particularly people who want to drive themselves to birding sites rather than taking public transportation and also want to book reservations directly with lodgings and reserves rather than using a ground agent or tour company. Many trip reports provide GPS waypoints for navigation. I used GoogleEarth/ Maps, which worked fine for most locations (not for El Paujil reserve). I paid $10/day for AT&T to hook me up to Claro, Movistar, or Tigo through their Passport program. Others get a local SIM card so that they have a Colombian number (cheaper, for sure); still others use GooglePhones, which provide connection through other providers with better or worse success, depending on the location in Colombia. For transportation, I used a rental 4x4 SUV to reach places with bad roads but also, in northern Colombia, a subcompact rental car as far as Minca (hiked in higher elevations, with one moto-taxi to reach El Dorado lodge) and for La Guajira. I used regular taxis on few occasions. The only roads to sites for Fuertes’s Parrot and Yellow-eared Parrot could not have been traversed without four-wheel drive and high clearance, and this is important to emphasize: vehicles without these attributes would have been useless, or become damaged or stranded. Note that large cities in Colombia (at least Medellín, Santa Marta, and Cartagena) have restrictions on driving during rush hours with certain license plate numbers (they base restrictions on the plate’s final numeral). -

21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -
Colombia Trip Report Santa Marta Extension 25Th to 30Th November 2014 (6 Days)
RBT Colombia: Santa Marta Extension Trip Report - 2014 1 Colombia Trip Report Santa Marta Extension 25th to 30th November 2014 (6 days) Buffy Hummingbird by Clayton Burne Trip report compiled by tour leader: Clayton Burne RBT Colombia: Santa Marta Extension Trip Report - 2014 2 Our Santa Marta extension got off to a flying start with some unexpected birding on the first afternoon. Having arrived in Barranquilla earlier than expected, we wasted no time and headed out to the nearby Universidad del Norte – one of the best places to open our Endemics account. It took only a few minutes to find Chestnut- winged Chachalaca, and only a few more to obtain excellent views of a number of these typically localised birds. A fabulous welcome meal was then had on the 26th floor of our city skyscraper hotel! An early start the next day saw us leaving the city of Barranquilla for the nearby scrub of Caño Clarín. Our account opened quickly with a female Sapphire-throated Hummingbird followed by many Russet-throated Puffbirds. A Chestnut-winged Chachalaca by Clayton Burne White-tailed Nightjar was the surprise find of the morning. We added a number of typical species for the area including Caribbean Hornero, Scaled Dove, Green-and-rufous, Green and Ringed Kingfishers, Red-crowned, Red-rumped and Spot-breasted Woodpeckers, Stripe-backed and Bicolored Wrens, as well as Black-crested Antshrike. Having cleared up the common stuff, we headed off to Isla de Salamanca, a mangrove reserve that plays host to another very scarce endemic, the Sapphire-bellied Hummingbird. More good luck meant that the very first bird we saw after climbing out of the vehicle was the targeted bird itself.
