Table 3. Prey of Tyto alba (Yankari Game Reserve) and at Futuk, 16 km east of the reserve WIKKI FUTUK see text for details x ^weights based on mean values of weights from the collection or from any other museum speci­mens, and in the case of unidentified species, on weights of species of similar size. In addition to the species collected by trapping, a number of new record for the reserve have been found in the owl pellets. These include two widespread species of-bats (Taphozous mauritianus and Nycteris major ) and a Pipistrellus that could not be identified further due to its fragmentary remains. The most interesting records are the shrews. In addition to the species trapped, Croci­dura flavescens , C. poensis and several unidentified Crocidura were found in the pellets. The pel­lets from Futuk also contained Suncus infinitcsimus, which is only the second known record of this species for Nigeria, in fact for West Africa (HEIM DE BALSAC & MEESTER, 1971). Further work on the shrew remains in these pellets is required before all the details can be published. The ro­dent JJa^vinj^_jjicomtus was found in owl pellets, but has never been trapped in Yankari G.R.. Lemniscomys barbarus, which was trapped by HAPPOLD (1970) but not by me, was found in pel­lets from Wikki and Futuk, and Arvicanthis niloticus was found in pellets at Futuk and may well occur within the reserve.
