“…Such nonindependent mate choice (45) has been termed ''mate copying'' (3)(4)(5)(6)(7)(8). According to this proposal, the mate choice of a particular male by one female causes an increased preference for that same male by another female.…”

“…ISI and public information are suggested to be used when individual information may be ambiguous (2) such as is provided by the unstimulated uninfected and infected males used here. Inexperienced naive females may, thus, use the putative olfactory interests of other females and obtain information about male quality in a manner similar to that suggested for visually based mate copying in birds and fishes (1)(2)(3)(4)(5)(6)(7)(8). In a broader context, females can also be considered to be ''trusting'' the mate interests or preferences of other females.…”

“…The use of inadvertently produced and publicly available information (''public information;'' ref. 1), in which some cues of one female's mate choice decision influences another female's mate choice (''mate copying''), is reported in several species of birds and fish (3)(4)(5)(6)(7), with even reversals of mate choice decisions indicated (8). Although social influences on human mate choice are suggested, the use of ISI in determining the mating and social preferences of mammals remains to be established (1,2,9).…”

Social information can be acquired either directly or indirectly from cues inadvertently produced by individuals with similar interests and requirements (''inadvertent social information,'' ISI). These inadvertent cues provide ''public information'' that other individuals can use to guide their behavior. We show here that female mice use olfactory ISI to determine their choice of, and responses to, males and that the use of this ISI involves the gene for oxytocin (OT). Female mice (OT wild type and CF-1 strain) displayed a significant interest in, and choice of, the odors of uninfected males of varying sexual status that were associated with the odors of an another estrous female. This recognition of, and choices for, specific, individual male odors was evident 24 h later. Female mice also distinguished between males subclinically infected with the gastrointestinal nematode parasite, Heligimosomoides polygyrus, and nonparasitized males, displaying aversive responses (analgesia, increased corticosterone) to, and avoidance of, the odors of infected males. The presence of the odors of another estrous female with that of the infected male, which are indicative of potential mate interests, attenuated these aversive responses and resulted in a choice for the odors of infected male. OT genedeficient (knockout) females were impaired in their use of this ISI to modulate their responses to either uninfected males of differing sexual states or infected males. These findings suggest that OT genes are necessary for the processing of inadvertent social information and likely the integration of both direct and indirect social information.

“…Haematozoa, or blood parasites, may lead bird species to extinction ( VAN RIPER III et al, 1986), and alter sexual selection and the evolution of plumage color (HAMILTON;ZUK, 1982;PRUETT-JONES et al, 1990;RYAN, 1991). Infected individuals may be more susceptible to predators and less able to establish territories (ANDERSON; MAY, 1979).…”

Parasites may lead bird species to extinction, affect host temporal and spatial population dynamics, alter community structure and alter individuals' social status. We evaluated blood parasite prevalence and intensity according to bird families and species, among 925 birds that were caught in 2000 and 2001, in the Atlantic Forest in the State of Minas Gerais, Brazil. We applied Giemsa staining to thin blood smears, to detect blood parasites. The birds (n = 15.8%) in 11 families, were infected by at least one parasite genus, especially Muscicapidae (28.3%) and Conopophagidae (25%). Among the 146 infected birds, Plasmodium was detected in all bird families and had the highest prevalence (54.8%). Trypanosoma, Haemoproteus and microfilaria had lower prevalence rates (23.3, 23.3 and 2.1%, respectively). Birds caught during the rainy season were more infected than birds caught during the dry season. The overall low prevalence of blood parasites in birds is similar to the patterns found elsewhere in the Neotropical region.Keywords: Brazil, microscopy, parasites, Plasmodium, Trypanosoma, Haemoproteus. ResumoParasitos podem levar espécies de aves à extinção, afetar as dinâmicas temporais e espaciais dos hospedeiros, alterar a estrutura de comunidades e o status social de indivíduos. Avaliou-se a prevalência e a intensidade de parasitos em famílias e espécies de 925 aves capturadas, entre 2000 e 2001, na Mata Atlântica de Minas Gerais. Foram coradas com Giemsa extensões de sangue para detectar parasitos hematozoários. As aves (n= 15,8%) 11 famílias estavam infectadas por pelo menos um gênero de parasito, especialmente Muscicapidae (28,3%) e Conopophagidae (25%). Entre as 146 aves infectadas, Plasmodium foi detectado em todas as famílias e possuiu a maior prevalência (54,8%). Trypanosoma, Haemoproteus e microfilaria possuíram baixas prevalências (23,3, 23,3 e 2,1%, respectivamente). Aves capturadas durante a estação chuvosa estavam mais infectadas do que aves capturadas durante a estação seca. A baixa prevalência geral de parasitos do sangue das aves é semelhante aos padrões encontrados em outras localidades da região Neotropical.

“…For example, although hematozoa appear to infect a larger proportion of colonially than solitarily nesting birds in one African sample (17), prevalence in north temperate species appears generally unrelated to nest location, mating system, habitat type, and elaboration of secondary sexual characteristics (18)(19)(20). Prevalence of avian hematozoa does, however, bear a strong association with taxonomic group at the family level (1,12,13). At present, the causes of this variation are not understood.…”

Variation in prevalence of avian heiatozoais related to taxonomic affDiation at the level of the family or subfamily but not of the genus within families. Prevalence is comparatively insensitive to the influences of habitat and season; however, temperate species have higher incidences of infection than tropical species belonging to the same himilies. Among taxa of nonraptorial altrical landblrds, hematozoan prevalence is inversely related to the length of the incubation period but shows little relationship to body size and rate of postnatal development. This finding suggests a possible link between the duration ofembryonic development and the ability to resist or control infection, possibly due to maturational processes in the avian immune system.The proportion of individuals with microscopically detectable infections of blood parasites (hematozoan prevalence) varies widely among species of birds (1)(2)(3). This variation suggests differences in exposure to parasite vectors, vulnerability to parasites, or ability to resist or control infection. To the extent that resistance falls under genetic control, parasites have been implicated in the evolution of sexual reproduction (4), genetic polymorphism (5), and sexually selected characters (6-9); certainly, they may influence survival and reproductive success (10), even causing extinction of susceptible populations (11). Some ofthe variation in prevalence of hematozoa has been linked to locality (1, 12), habitat, diet (13), season (14, 15), and, in tropical latitudes, to plumage brightness (13,16). Other factors have been shown to be unimportant. For example, although hematozoa appear to infect a larger proportion of colonially than solitarily nesting birds in one African sample (17), prevalence in north temperate species appears generally unrelated to nest location, mating system, habitat type, and elaboration of secondary sexual characteristics (18)(19)(20). Prevalence of avian hematozoa does, however, bear a strong association with taxonomic group at the family level (1,12,13). At present, the causes of this variation are not understood.In this report, I relate hematozoan prevalence to embryonic and postnatal development rate and demonstrate that prevalence is inversely related to the length of the incubation period. I speculate that this correlation arises from a direct relationship between immunocompetence and period of embryonic growth. Long incubation periods might allow increased proliferation of B stem cells and greater diversification of the variable region of immunoglobulin light chain genes before they are expressed as antibody. MATERIALSParasite data were obtained from literature surveys of field studies in the nearctic (1) and the neotropical regions (2, 3).To restrict the scope of the survey with respect to habitat, diet, and development type, I consider only nonraptorial (i.e., excluding birds of prey) altricial (i.e., those with highly dependent neonates, thereby excluding gallinaceous birds and ducks and geese) terrestrial birds.
