“…To quantify ectoparasite load, I examined body feathers 2–4 months after they were collected. Parasitic chewing lice (Insecta: Phthiraptera) are common in feral peafowl (Petrie et al 1996, Stewart et al 1996, Hollamby et al 2003), and remained attached to the feather barbs, where they were counted under a dissecting microscope; other ectoparasites were not observed, neither on the feathers nor on the birds during handling. A direct energetic cost of feather lice has been demonstrated experimentally in birds (Booth et al 1993), and increased infestation can result from poor health states (e.g.…”

The crest of the peafowl: a sexually dimorphic plumage ornament signals condition in both males and females

Both male and female peafowl grow crests on top of their head – iridescent blue in males, dull iridescent green and brown in females – but the potential signal function of this plumage ornament is unknown. In this study, peafowl crests were measured in three feral populations, and morphological variation in this ornament was studied in relation to body condition (body mass in relation to tarsus length) and health (white blood cell concentration and ectoparasite load). Prior to the start of the breeding season, male crests are wider with greater pennaceous area, and are more likely to have all feathers grown out compared with female crests. Only crest length changed with measurement date, increasing over time; in males, crest measurements were not related to the extent of train feather development. Crest morphology is a potential signal of individual health and condition in both sexes, but in different ways. In females, the amount of crest plumage grown out to its full extent was related to body condition at the start of the breeding season, whereas in males, the size and pennaceous area of the ornament were related to ectoparasite load. Observations of within‐sex agonistic behaviour suggest a possible role for the crest ornament in status signaling in males, because males that engage in more aggressive interactions tend to have wider crests. There was no evidence for a relation between crest morphology and agonistic behaviour in females.

Aims: To examine and explore chewing lice (Phthiraptera) species found in Peafowls in Pakistan. To find out more species and compare these species with previously known species of chewing lice found on Peafowls. Study Design: The genus Goniodes Nitzsch, 1818 is specifically found on gallinaceous hosts all over the world, represented by 100 species. It is very clearly identifiable for its circumfasciate head and somehow angulated temples of the head, antennae always heteromorphic; thorax and abdomen also very peculiar in its morphology, the abdominal segment I always larger and expanded laterally. Parasitological investigation of Peafowls was undertaken to find out the chewing lice infestation in Sindh, Pakistan. Place and Duration of Study: Department of Zoology, University of Sindh, Jamshoro, Sindh, Pakistan. Between 2016 and 2017. Methodology: Peafowl, Pavo cristatus L. 1758 was examined during the present study for chewing lice collection; chewing lice were processed for the permanent mount through the standard method and were studied under high magnification microscope for illustration and identification. Results: During the examination of chewing lice, the genus Goniodes was recovered from Pavo cristatus for the first time from Sindh province, Pakistan. Out of 18 peafowls, seven were infested, contained 28 specimens of two species, G. dissimilis Denny 1842 and G. meinertzhageni Clay 1940 were isolated from Thatta, Karachi, Jamshoro, Hyderabad and Mirpur Khas districts of Sindh. Both species G. dissimilis and G. meinertzhageni were recorded first time from Pakistan, hence put on new record at country level for Indian Peafowl. A key for the identification of all Goniodes species found on the peafowl has also been presented along with their detailed morphological descriptions and morphometric features. Conclusion: Two species of chewing lice of the genus Goniodes were collected and identified and were compared with each other to clarify their morpho-taxonomical characteristics in both species.

“…Researches reveal that the lice do not only affect the vitality and productivity of its hosts but also act as reservoir and transmitter of strains of various infectious pathogen among them (Derylo, 1974 andSaxena et al, 1985). The prevalence and infestation intensity of different phthirapteran ectoparasites on certain avian hosts namely, sparrow (Hoyle, 1938 andWoodman andDicke, 1954), starlings (Boyd, 1951), blackbirds (Baum, 1968), alcids (Eveleigh and Threlfall, 1976), procellariiform birds (Fowler et al, 1984), wood ducks (Thul, 1985), reed bunting (Fowler and Williams, 1985), Wilson's petrels and storm petrels (Fowler and Price, 1987), leach's petrels (Fowler and Hodson, 1988), Manx shearwaters (Fowler and Shaw, 1989), five shorebird species (Hunter and Colwell, 1994), house martins (Clark et al, 1994), swifts (Lee and Clayton, 1995), pied flycatcher (Potti and Merino, 1995), peacocks (Stewart et al, 1996), Spanis raptors (Perez et al, 1996), bee eaters (Kristofik et al, 1996;Hoi et al, 1998 andDarolova et al, 2001), pigeon (Dranzoa et al, 1999;Mushi et al, 2000), california quail (Gonzalez et al, 2003), Indian Red Avadavat (Gupta et al, 2007) have been noted by selected workers. Only a few workers have examined birds belonging to different orders from this point of view (Ash, 1960;Klockenhoff et al, 1973;Stranger and Palma, 1998;Oniki, 1999).…”

A total of 1,020 poultry birds belonging to twelve different localities of Jaunpur district were surveyed during May 2006 to April 2007 to record the prevalence rate of Eomenacanthus stramineus. Prevalence of E. stramineus was noted more or less similar in both the sexes (Male -38% and Female -39%). Maximum birds bore very low infestation (32%) while only 7% birds exhibited very heavily infestation. Host sex, feather colour and locality had negligible effect on prevalence rate. However, prevalence rate remained slightly higher on birds with poor plumage/health. Significant positive correlation existed between mean monthly prevalence rate and mean monthly temperature as well as photoperiod. Mean monthly incidence rate were recorded higher during summer (May and June) as compared to winter months.
