Birds’ populations are being threatened by parasites that have not received adequate attention by parasitologists. This study aimed at evaluating the abundance and diversity of ectoparasites of the wild birds in Pandam Wildlife Park. A systematic five-month study of ectoparasites was conducted. Sixty-two (62) birds were trapped using mist nets and examined for ectoparasite infestation. Wool soaked with 70% ethanol, using gloved-protected-hand; ectoparasites were carefully extracted, preserved in sampling bottles containing 70% alcohol for morphological identification. A wide spectrum insecticide (0.09% tetrametrin and 0.45 piperronyl) was used to pulverize tiny parasites on the feather over a white paper. Overall, 4,066 ectoparasites belonging to 5 orders, 8 families, and 24 species were identified from the trapped birds. Fiftysix 56(90.3%) birds were found to be infested with ectoparasites, while 6(9.7%) had none. Phthirathera, and Siphonaptera were the most and least abundant respectively. The highest parasites found were lice (96.60%) and the least, fleas (0.02%). Wing predilection site had the highest infestation rate (83%), and the lowest was the leg (0.37%). The most caught and most infested bird species was the West African thrush bird Turdus pelios (14.28%), followed by the Red-checked cuckoo-shrike and Bronze manikin (10.70% and 7.14%) respectively. Least species of bird infested among others, were the African paradise king fisher, Blue-throated brown sunbird, Blue-spotted wood dove, and Blue-breasted fire finch (1.79%). Nevertheless, there was no significant difference (p>0.05) in the rate of infestations among the caught and examined bird species. The study provided useful insight and knowledge on how diverse and abundant ectoparasites of bird species are in this park and possible vector-borne diseases that may have zoonotic potential.
