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 activiti...

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...

A 16-year-old female Indian peafowl (Pavo cristatus) died two days after recognition of conjunctivitis in the right eye, anorexia and depression. Gross necropsy revealed a thick pseudomembrane under the eyelid and hydropericardium. Histopathological examination revealed hepatocellular necrosis, sinusoidal and vascular congestion and infiltrated inflammatory cells. Infiltration by inflammatory c...

Effects of mating sex ratios on production performance in Indian peafowl were investigated at PunjabWildlife Research Institute, Gatwala Faisalabad. Research was conducted from May through August 2007 toexplore the most productive mating sex ratio. The sex ratios have a significant effect on egg production.Maximum mean eggs (1.63) were produced by the sex ratio 1:2 while maximum egg fertility (...

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...

Effective use of available cage spaces in wild bird breeding systems captivity is ofprime economic concern. Present study was carried out at Punjab Wildlife Research InstituteFaisalabad to evaluate effect sizes on reproductive performance the Indian Peafowl (Pavo cristatus). Three groups; A, B and C were selected nurtured under threedifferent sizes, viz. 30, 21 12 square meters with an space 10...

One of the classic examples of an exaggerated sexually selected trait is the elaborate plumage that forms the train in male peafowl Pavo cristatus (peacock). Such ornaments are thought to reduce locomotor performance as a result of their weight and aerodynamic drag, but this cost is unknown. Here, the effect that the train has on take-off flight in peacocks was quantified as the sum of the rate...

An outbreak of highly pathogenic avian influenza (HPAI) virus subtype H5N1 was first diagnosed in a "backyard" flock of peafowl (Pavo cristatus) raised on palace premises in the Kingdom of Saudi Arabia in December 3, 2007. The flock consisted of 40 peafowl, and their ages ranged from 3 to 5 years old. Affected birds suffered from depression, anorexia, and white diarrhea. Four dead birds were su...
