ABSTRACT

Parasites play an important role in ecosystems including shaping the populations and communities of their hosts. Majority of arthropod parasites transmit vector-borne zoonotic diseases, some of which are transmissible to humans and livestock. Birds are a host to a variety of arthropod parasites. Despite their importance, parasites continue being excluded in most ecological inventories. For example, the diversity of avian fauna in Kenya is fairly well known yet little is known about their ectoparasites. The aim of this study was to determine the diversity and abundance of lice of two endemic subspecies of birds, Speckled Mousebird Colius striatus kikuyuensis and Red-capped Lark Calandrella cinerea williamsi in two adjacent but ecologically different ecosystems: the cooler highlands of Nyandarua County and the warmer and lower altitude Naivasha area of Nakuru County. The two hosts were chosen because they are widely distributed in both study areas, exhibits varying behaviour and occupy specific niches. Lice were collected from 269 Speckled Mousebirds and 327 Red-capped Larks that were trapped using mist nets, and quantitatively examined using the dust-ruffling technique. A small amount of blood (c.100μl) was preserved as a dry spot from which DNA was extracted to determine the host’s sex through PCR protocol targeting the CHD gene located on the avian sex (Z) chromosome. Two genera of lice, Colilipeurus sp. and Colimenopon sp., were recorded on Speckled Mousebird. Red-capped Lark had three lice genera: Philopterus sp., Menacanthus sp. and Ricinus sp., the first two being new host records. Louse distribution among hosts was aggregated (Poulin’s discrepancy index D: Speckled Mousebird 0.571, Red-capped Lark 0.909). Louse prevalence was high in Speckled Mousebird (90%) compared to Red-capped Lark (17%). Prevalence between the host species was significantly different (unconditional exact test p
