Abstract A major barrier to advancing ornithology is the systemic exclusion of professionals from Global South. recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed long-standing pattern highlighting individuals, knowledge, views North, while largely omitting perspectives people based within Neotropics. Here, we review current strengths opportunities practice ornithology. Further, discuss problems with assessing state...

Introducción: los perros son uno de animales con cuales las personas tienen mayor vínculo y afecto. Sin embargo, su presencia dentro cerca áreas naturales protegidas puede entenderse como una amenaza para la fauna silvestre, ya que pueden hostigar, cazar e incluso transmitir enfermedades. Esta investigación apunta a conocer qué tipo relaciones se generan entre perros, otros en el valle del Río Manso, provincia Negro, preguntas orientaciones surgen estos enlaces diversos seres vivos teorías....

Abstract Woodpeckers are considered keystone species for webs of cavity nesters and habitat resource specialists that strongly depend on availability trees suitable excavation. Most studies carried out in northern hemisphere temperate coniferous forests emphasize the importance old growth stages or large dead as builders.

The Magellanic Woodpecker (Campephilus magellanicus (King, 1827)) is a large, vulnerable species exhibiting geographic range retraction. We analyzed the size and location of forest areas used by these woodpeckers in consecutive years (2010–2012), as related to habitat characteristics, an old-growth lenga (Nothofagus pumilio (Poepp et Endl.)

Parasites can exert selection pressure on their hosts through effects survival, reproductive success, sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability. Consequently, hemoparasites have become the focus of recent avian studies. Infection varies significantly among taxa. Various factors might explain differences infection taxa, including habitat, climate, host density, presence vectors, life history immune defence....

Abstract In the Northern Hemisphere, several avian cavity excavators (e.g., woodpeckers) orient their cavities increasingly toward equator as latitude increases (i.e. farther north), and it is proposed that they do so to take advantage of incident solar radiation at nests. If a key driver orientations globally, this pattern should extend Southern Hemisphere. Here, we test prediction are oriented northward higher colder) latitudes in Hemisphere describe preferred entrance direction(s) 1,501...

During the 2003–2004 and 2004– 2005 nesting seasons, we studied parental behavior at seven Magellanic Woodpecker (Campephilus magellanicus) nests in Argentine Patagonia. Food items delivered to nestlings included wood-boring larvae (57.6%), arachnids (13.1%), vertebrates (4.6%, including a bat, lizards, avian eggs nestlings). Less frequent were adult insects, caterpillars, pupae. Small, unidentified invertebrate prey made up 19.8% of observations. Males most large (wood-boring vertebrates;...

ABSTRACT We examined the diet of White-throated Hawks (Buteo albigula) during incubation and nestling periods in southern temperate forest Argentina. Pellets (N= 74) prey remains 59) were collected at 10 nests from 1998 to 2003, preys delivered two monitored 2001–2002 breeding seasons. fed on small mammals, birds, lizards, insects. The three methods identifying (pellets, remains, direct observation) produced different results. All types except large birds detected pellets, arthropods may...

ABSTRACT Cinclodes ovenbirds (Furnariidae) inhabit open habitats of South America, usually near water. The Buffwinged (C. fuscus) was recently recognized as a separate species, and data on its natural history are scarce. This species breeds in Patagonia winters further north Argentina adjacent countries, although some populations Chile breed the Andes winter Pacific coast. few nests that have been described were placed holes cliffs, bridges, road cuts Patagonian landscapes. Based these data,...

European starlings (Sturnus vulgaris) were introduced ca. 40 years ago to South America, where they naturalized central and northern Argentina, now reaching some neighboring countries. While Patagonia (southern Argentina Chile) has remained free of (ES) in the past, are present along its boundary.
