چکیده

Behavioral observations on Indian peafowl Pavo cristatus in the Shivalik landscape of North India were carried out during their mating period, between 31 March and 21 May 2006. Behaviors of peafowl were recorded using scan samples. Overall, females, sub-adult males and adult males spent different proportions of time in different activities, and the proportion of time spent on different activities varied during the mating season. Visitation by females influenced the frequency of displays by adult male Indian peafowl during this period. The study reveals that peafowl behavior in its native habitat broadly conforms to that documented from captive and introduced populations. However, there were some differences between the wild and captive populations in vocalizations, maintenance behavior and spatial distribution of adult males. Since the time spent engaging in these behaviors may affect the cost of display, these results emphasize the need to assess the signaling cost in situ where the behavior evolved.

Eye and head movements shape gaze shifts in Indian peafowl.

Animals selectively direct their visual attention toward relevant aspects of their environments. They can shift their attention using a combination of eye, head and body movements. While we have a growing understanding of eye and head movements in mammals, we know little about these processes in birds. We therefore measured the eye and head movements of freely behaving Indian peafowl (Pavo cris...

Selective attention in peacocks during assessment of rival males.

Males in many species compete intensely for access to females. In order to minimize costly interactions, they can assess their rivals' competitive abilities by evaluating traits and behaviors. We know little about how males selectively direct their attention to make these assessments. Using Indian peafowl (Pavo cristatus) as a model system, we examined how males visually assess their competitor...

Avian tuberculosis was diagnosed histopathologically and microbiologically in two pheasants (Phasianus colchicus) and two peafowl (Pavo cristatus) kept in the same aviary. The incidence of avian tuberculosis in the aviary was 6%. Non-mineralized caseogranulomas were present in the liver (3 cases), spleen (3 cases), intestine (2 cases), lung (2 cases), and cloaca (1 case). Granulomas in the lung...
