Despite having a rich avifauna in Iran, limited number of studies have been conducted on lice fauna of wild birds in this region. This study was carried out to identify lice species of passerine birds in East of Iran. A total of 106 passerine birds of 37 species were captured. Their bodies were examined for lice infestation. Fifty two birds (49.05%) of 106 captured birds were infested. Overall 465 lice were collected from infested birds and 11 lice species were identified as follow: Brueelia chayanh on Common Myna (Acridotheres tristis), B.

Up to the present, a total of 109 species belonging to 50 genera of lice have been recorded from animals and humans, according to the morphological identifi cation. Among the avian lice, a total of 43 species belonging to 22 genera were identifi ed in Ischnocera (Philopteridae). 35 species belonging to 14 genera in Menoponidae were detected and only 1 species was found in Laemobothriidae in Amblycera. Among the mammalian lice, a total of 20 species belonging to 8 genera were identifi ed in Anoplura. 8 species belonging to 3 genera in Ischnocera were determined and 2 species belonging to 2 genera were detected in Amblycera in the mammalian lice.

However, no study has documented straggling (when lice are found on atypical hosts) rates within these lineages. We used the fact that the Galapagos Hawk, Buteo galapagoensis (Gould) (Falconiformes) feeds on the Galapagos Dove Zenaida galapagoensis Gould (Columbiformes) within an ecologically simplified setting. The Galapagos Dove is the only typical host of Columbicola macrourae (Wilson) and Physconelloides galapagensis (Kellogg and Huwana) in Galapagos. We quantitatively sampled and found these lice on both bird species. A DNA barcoding approach confirmed that stragglers were derived from Galapagos doves. We also collected a Bovicola sp. louse, likely originating from a goat (Capra hircus). On hawks, C. macrourae was significantly more prevalent than P. galapagensis. On doves, the two lice were equally prevalent and abundant. Differences in prevalence on hawks was a function of differences in straggling rate between lice, and not a reflection of their relative representation within the dove population.

Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional signifi- cance of some of these defenses has been well documented. Others have barely been studied, much less tested rigorously. In this article we review the evidence - or lack thereof - for many of the purported mechanisms birds have for dealing with ectoparasites. We concentrate on features of the plumage and its components, as well as anti-parasite behaviors. In some cases, we present original data from our own recent work. We make recommendations for future studies that could im- prove our understanding of this poorly known aspect of avian biology.

  • Effects of Host Sociality on Ectoparasite Population Biology
    J. Parasitol., 90(5), 2004, pp. 939–947 ᭧ American Society of Parasitologists 2004 EFFECTS OF HOST SOCIALITY ON ECTOPARASITE POPULATION BIOLOGY Noah Kerness Whiteman and Patricia G. Parker Department of Biology and International Center for Tropical Ecology, 223 Research Building, 8001 Natural Bridge Road, University of Missouri– St. Louis, St. Louis, Missouri 63121. e-mail: [email protected] ABSTRACT: Theory predicts a positive relationship between parasite infection intensity and host density. However, this gener- alization is complicated in natural systems by differences in life history among parasite taxa, e.g., transmissibility. Accordingly, predictions relating host density to parasite load should be specific to each parasite taxon. To illustrate this, we studied parasites that differed greatly in life history in the context of the Galapagos hawk’s (Buteo galapagoensis) variably cooperative mating system. Two louse (Phthiraptera) species were collected: Colpocephalum turbinatum (Amblycera), with 53 host species, and Degeeriella regalis (Ischnocera), with 10 host species, although B. galapagoensis was the only known Galapagos host. Sixty territorial adult male hawks from 26 groups of 1–6 males were quantitatively sampled for lice. Average abundance and intensity of C. turbinatum but not D. regalis were significantly larger in large groups of hawks than small groups. Males from the same polyandrous group harbored significantly correlated abundances of C. turbinatum but not D. regalis. Prevalence, average abun- dance, and intensity of C. turbinatum were significantly higher than D. regalis. These are the first results to demonstrate significant differences in a suite of population responses between these louse suborders in the context of host sociality. There are several presumed benefits and costs to group living (de Vries, 1973, 1975; Faaborg et al., 1980, 1995; Faaborg, (Alexander, 1974).
