ResumoDURING September 1931 to June 1932 I was stationed at Mazabuka, a small town in a farming centre about 30 miles on the Livingstone side of Kafue. The Native Education Department headquarters and the Jeanes Middle and Elementary Schools are situated on a gentle slope about a mile and a half from the town, and the notes here refer only to this station and are not concerned either with the town itself or with the surrounding country. The earlier months were naturally largely occupied in making acquaintance with the birds, but I nevertheless started sample counts (see (6) for an explanation of this method) in September. In the middle of November I began to supplement these by a daily list of all the species observed on the station. The value of this method has already been pointed out by Linsdale (2). By 29 June my list had come to include 119 species, and it is significant that one was added on each of the last 2 days. In addition, four or five species had been seen before the list was begun but were not observed later. It is particularly unfortunate that it was not possible to continue these observations for at least a further 2 months and so complete the year. No complete counts of the station were undertaken. The advantages and disadvantages of the sample count method have already been discussed (6). The daily list has the same defects, but they are more pronounced. This method has been independently evolved by Linsdale (2, 3), who considers it extremely valuable. It is, in any case, useful as a check on the sampling and one or two interesting features emerge from a consideration of its results. It must nevertheless be borne in mind that the two sets of figures do not measure
