species like Black Lion Tamarin Leontopithecus chrysopygus (Mikan,
1823) (Monteiro et al. 2009).
A wooden observation tower, known locally as “mirante”,
was installed at the station highest point, 822 m altitude, on a
Semideciduous Forest stretch (23° 24’ 29” S and 48° 22’ 03” W). It
has approximately 20 m high and its original function is to assist in
early re detection. We used a digital camera trap Tigrinus - Sony
Cyber-Shot 14 megapixel to obtain the photograph.
Results and Discussion
On July 26 2012 a white egg was found on the tower at 11 m
height (Figure 1). A week later, the camera trap was installed just
ahead of the egg, about 1.5 m apart, and left for 6 h. An adult was
photographed next to the egg (Figure 2). On August 26 2012 the egg
had disappeared and the adults did not return. Cuneo (1968) reports
a 50 to 53 day incubation period. Only 30 days passed since our
discovery, which we believed happened near the laying date due to
frequent visits to area. The egg was probably preyed upon, predation
of eggs and nestlings is a frequent cause of nest failure in vultures
(Cuneo 1968, Sarasola et al. 2000).
This report represents the first documented record of this
species for Estação Ecológica de Angatuba (Willis & Oniki 2003,
Monteiro et al. 2009, Centro... 2012, Wikiaves 2012). Among
Cathartidae, use of manmade structures has also been reported for
Black Vulture Coragyps atratus (Bechstein, 1793) (Hill III & Scherer-
Neto 1991, Vasconcelos 1997). Flexibility in choice of nesting sites
Introduction
The King Vulture is an iconic member of the Neotropical fauna,
thanks to its size, color and natural rarity. Although not considered
globally threatened, their populations are in decline, mostly due to
habitat loss and poaching (BirdLife… 2012). Available population
estimates suggest fewer than 50,000 individuals all over its original
distribution area from Mexico to Argentina, and total number of
mature specimens is less than 10,000 (BirdLife… 2012).
In the state of São Paulo, southeastern Brazil, the King Vulture
is considered threatened with extinction and listed in the category
“vulnerable” (São Paulo 2008). Even with increasing recent records
in this state (Wikiaves 2012), there are scarce nesting observations
in São Paulo (Silva & Regalado 1998, Giorgetti & Fonseca 2009).
King Vulture nests have been recorded in several sites, such as
ground, rock walls, hollow dead trees and on emergent tree branches
(Smith 1970, Ramo & Busto 1988, Sick 1997, Silva & Regalado
1998, Schlee 1995, 2000, Carvalho-Filho et al. 2004, Giorgetti &
Fonseca 2009). In this paper we report a nest on a manmade structure.
Material and Methods
The observations took place in the Estação Ecológica de
Angatuba, Paranapanema river basin southwestern São Paulo state
(Figure 1). This 1,394.15 ha ecological station preserves important
remnants of Semideciduous Forest and Cerrado, housing emblematic

probably works as a pre-adaptation to use of certain buildings by
vulture species.
Generally, reserve managers are aware of negative impacts that
manmade structures can have on wildlife, for example collisions
with window panes (Klem 2009). However, our report indicates the
possibility that some of these structures can be used in order to favor
certain species, including endangered ones. Researchers and other
professionals associated with the management of protected areas
should be aware of this possibility.

... Yet, two eggs from wild birds come from countries with no breeding records on literature, Peru and Bolivia. More detailed data come from only three countries: Panama (Lundy 1957;Wetmore 1965;Smith 1970), Venezuela (Ramo and Busto 1988;Schlee 1995), and Brazil (Carvalho-Filho et al. 2004;Petri et al. 2013; WA2423099; WA2392238), but each of these referring to one or two nests only. The only thoroughly monitored nest is the one by Carvalho-Filho et al. (2004). ...
... The King Vulture has variable nest site choice. Although some nests were at ground level (Smith 1970;Schlee 1995), the species may also nest up to~10 m high in small caves (Silva and Regalado 1998), holes in trees (Ramo and Busto 1988) or even man-made structures (Petri et al. 2013)-and one even higher nest (apparently dozens of meters aboveground, on a cliff) was reported (Carvalho-Filho et al. 2004). Clutch size was always one. ...
... However, there is also evidence suggesting that the species may take advantage of some human activities (Olmos et al. 2006). The nest record in a man-made structure (Petri et al. 2013) shows that King Vultures might be able to use artificial breeding sites. Artificial nest sites mimicking real ones could be a useful strategy to bolster raptors' populations (Liébana et al. 2013), and it was suggested that such man-made nests may even help improve ecosystem services provided by these birds (Murúa et al. 2004). ...

New World vultures (Cathartidae) have essential roles in ecosystem functioning, but are susceptible to increasing anthropogenic impacts. Knowledge of several breeding, behavioral, and distributional parameters of Neotropical vultures is poorly organized and have not been properly reviewed. Here, we made a comprehensive review of original breeding records from museums, literature, and citizen science (WikiAves) for each of the six species of vultures occurring in the Neotropical region. These data were used to review breeding patterns and geographical distribution, and identify information gaps. The 567 records of breeding from the Neotropics assembled are very biased, mostly for Black Vulture Coragyps atratus (n = 319) and Turkey Vulture Cathartes aura (n = 166), and unevenly distributed among regions and subspecies. The four other species still have a great lack of knowledge about their breeding in the wild (Lesser Yellow-headed Vulture Cathartes burrovianus (n = 20), Greater Yellow-headed Vulture C. melambrotus (n = 2), King Vulture Sarcoramphus papa (n = 21), and Andean Condor Vultur gryphus (n = 30)). We show for the first time that Neotropical Cathartidae have convergent breeding seasons among sympatric taxa, delay start of breeding with increasing latitude, and have an allometric relationship between adult size and egg size. Nevertheless, larger samples of breeding data, especially from some regions and taxa, such as the two “Yellow-headed Vulture” species, are still needed. We also show that breeding traits could be helpful for preventive management and conservation strategies involving both expanding and decreasing populations of vultures in the Neotropics.
... The utilization of man-made structures for foraging and nesting may represent novel adaptations that permit the occupation of urban environments by birds. Documenting such adaptations is important in a context of an anthropogenically altered world where the area occupied by cities is increasing, which represents threats to many bird species (Loss et al. 2014, Woinarski et al. 2017) but ecological opportunities for others (Hill-III & Scherer-Neto 1991, Petri et al. 2013. Here, I report on a nest made by the Narrow-billed Woodcreeper Lepidocolaptes angustirostris in a mailbox in a suburban area (sensu Marzluff et al. 2001) in southeast Brazil. ...

Documenting the adaptations of birds to live in urban areas is important in a context of an anthropogenically altered world where such areas may represent novel ecological opportunities for birds. Here I report on a nest of the Narrow-billed Woodcreeper Lepidocolaptes angustirostris in a wooden mailbox in a suburban area. The nest was found in the first week of November 2016 with three eggs, and later two nestlings that died within approximately one week likely due to water leaking into the box. The ability of L. angustirostris to use man-made structures for foraging and nesting, and its typical occurrence in open areas (thus differing from the family pattern of predominantly forest species) are factors permitting the occupation of urban habitats. © 2018, Sociedade Brasileira de Ornitologia.

Esse estudo teve como objetivo registrar as percepções, conhecimentos e formas de interação existentes entre moradores do distrito de Messianópolis, município goiano de Moiporá, e as espécies de urubus existentes na região. Por meio de entrevistas, evidenciou-se que o conhecimento dos moradores sobre essas aves é incipiente. Quando existente, os saberes apresentados pelos entrevistados foram coerentes com dados da literatura. Propriedades medicinais e simbolismos supersticiosos também foram relatados. Assim, esse estudo amplia as informações referentes ao conhecimento popular em relação aos catartídeos, que ainda são bastante escassas no Brasil.

We studied nesting King Vultures (Sarcoramphus papa) between October 2001 and April 2003. The study was accomplished at a private reserve belonging to CAUAIA's farm, situated in Matozinhos, Minas Gerais, inside of APA CARSTE environmental protection area of Lagoa Santa, Minas Gerais. Incubation occurred in October and November 2001, and the development of the nestling lasted from late November 2001 to early in April 2002. The nest was located in a fissure 44 m above ground of a 70 m calcareous quarry. A single egg was found in the nest: it was white and measured 95.6 mm x 63.6 mm. The nestling left the nest 130 days after hatching. We collected eight pieces of finger bones of young oxen (Carpicus unaris).

Birds behave as if clear and reflective glass and plastic windows are invisible, and annual avian mortality from collisions is estimated in the billions worldwide. Outdoor flight cage and field experiments were used to evaluate different methods to prevent collisions between birds and windows. Stripe and grid patterns of clear UV-reflecting and UV-absorbing window coverings presented an effective warning that birds avoid while offering little or no obstructed view for humans. Birds used UV-reflected signals to avoid space occupied by clear and reflective sheet glass and plastic. Window coverings with effective UV-reflecting and UV-absorbing patterns as warning signals can prevent unintentional killing of birds from collisions with windows. One-way films that made the outer surface of windows opaque or translucent were successful in deterring bird strikes. Ceramic frit glass consisting of a visual pattern of densely spaced 0.32-cm diameter dots, 0.32 cm apart was an effective collision deterrent. Uniformly covering windows with decals or other objects that are separated by 5 to 10 cm was completely or near-completely effective in preventing strikes. Twice the number of window strikes occurred at non-reflective sheet glass compared to conventional clear panes. Continuous monitoring of windows revealed one in four bird strikes left no evidence of a collision after 24 hrs and, without continuous monitoring, 25% of bird strikes were undetected.
