A preliminary list of the vascular plants of the Tsavo National Park, Kenya, was prepared by Mr. J. B. Gillett and Dr. D. Wood of the East African Herbarium during 1966. This I found most useful during a two month vegetation survey of Tsavo, East, which I was asked to undertake by the Director of Kenya National Parks, Mr. P. M. Olindo, during ""the short rains"", December-January 1966-1967. Mr. Gillett's list covered both the East and West Tsavo National Parks which are considered by the Trustees of the Kenya National Parks as quite separate entities, each with its own Warden in Charge, their separate staffs and organisations. As a result of my two months' field work I decided to prepare a Check List of the plants of the Tsavo National Park, East, based on the botanical material collected during the survey and a thorough search through the East African Herbarium for specimens which had been collected previously in Tsavo East or the immediate adjacent areas. This search was started in May, carried out intermittently on account of other work, and was completed in September 1967.

The following notes are based on a small collection made in 1948 and 1949 and vegetational and faunal changes may well have occurred since then. Collecting was undertaken only sporadically and as opportunity offered and achieved a far from complete record of butterflies in the area, Lycaenids and Hesperiids in particular being poorly represented. Sufficient species were however taken to give a fair indication of relationships with adjoining areas. A few records are, I think, new to the Tanzania list. The Ngara district, with an area of 1,045 sq. miles, lies between fifty and eighty miles to the west of the southern end of Lake Victoria. The altitude varies from 4,200 to 6,000 feet a.s.l. and the rainfall, which occurs mainly between October and April, averages about forty inches a year.

One of us (Hedberg, 1964) has given a comprehensive account of the ecology of Afroalpine plants, without any specific mention of geocarpy as an adaptation to the constant solifluction that may be experienced throughout the year in certain habitats. Since the publication of this account, the present two authors have revisited high altitude vegetation in East Africa and the purpose of this paper is to draw attention to the phenomenon and to remark on the species that show it and their ecology.

This report covers the period 1st July 1967 to 30th June 1968. The number of birds ringed is higher than ever before, unfortunately it is doubtful whether this upward trend can be maintained. One of the most prolific ringers, Dr. D. J. Pearson, left East Africa in June 1968 and his contribution will be missed greatly, although it is probable that some other experienced ringers will be coming out from England towards the end of 1968. Ringing has continued to be centred around Kampala, Nakuru and Nairobi, with smaller amounts in Masindi, the Queen Elizabeth National Park, Kisumu and southern Tanzania. The number of ringers operating in the three countries is still very small indeed and, considering this, the amount of ringing done is highly satisfactory. The full list of birds ringed is given in Table 1; birds which are palearctic migrants are printed in bold type, others which are included in the palearctic fauna but which are also ethiopian are not so distinguished. The order is that of Mackworth-Praed & Grant and their numbers are given before the English names, the nomenclature follows these authors for the African species, whereas Vaurie is used for the palearctic birds.
A Note on the possible reproductive structures in Kenyan, Udotes orientalis A. & E. S. Gepp, ChlorophytaAuthor S.A. MoorjaniSource: Journal of East African Natural History 1969, pp 227 –229 (1969)More Less
The genus Udotea is pan-tropical with extra-tropical (Natal Coast) extensions. Udotea orientalis A. & E. S. Gepp is an Indo-Pacific species. It has been reported from Kenya (Gerloff, 1960; Isaac, 1967), Mosambique and Natal coast of South Africa (Isaac, 1956). The Siboga Expedition records include Zanizbar in the Indian Ocean list; in the Pacific Ocean it has been reported from Queensland (Australia), China Sea and Japan (A. & E. S. Gepp, 1911). U. orientalis is widespread along the Kenya coast but it is generally less common than U. indica A. & E. S. Gepp. A third species U. flabellum (Ell. & Soland) Howe has been recorded for the Kenya coast (Isaac, 1967), but so far has only been found in the Lamu region (personal communication). U. orientalis is primarily an alga of quiet or protected waters such as those to seaward of mangroves and in lagoons. It is sometimes found in more exposed situations but not so much as U. indica. The morphology of Udotea is well known and has been fully descriptionbed by Gepp (1911). There is, however, no certain information and few published records of the reproductive structures, and hence it is worthwhile recording the observations made on the Kenya material of U. orientalis.

A recent note by the van Lawick-Goodalls (1966) has descriptionbed, and illustrated with remarkable photographs, the manner in which the Egyptian Vulture, Neophron perconopterus (Linnaeus), breaks Ostrich eggs by lifting stones in its beak and throwing them at the eggs. In this connection the following account (Wood, 1877), published more than ninety years ago, is perhaps of interest: ""Two articles of diet which certainly do not seem to fall within the ordinary range of vulture's food are said to be consumed by this bird. The first is the egg of the ostrich, the shell of which is too hard to be broken by the feeble beak of the Egyptian Vulture. The bird cannot, like the l?mmergeier, carry the egg into the air and drop it on the ground, because its feet are not large enough to grasp it, and only slip off its round and polished surface. Therefore, instead of raising the egg into the air and dropping it upon a stone, it carries a stone into the air and drops it upon the egg. So at least say the natives of the country which it inhabits, and there is no reason why we should doubt the truth of the statement. The other article of food is a sort of melon ... ""

This brilliantly coloured bird is rarely seen. Most of the records are made as the result of it flying into a light at night while on local migrations. As the records are few, the following observation and summary of what Moreau, Praed & Grant have to say may be of interest. An African Pitta was brought to me by the night watchman of the Mwese Hospital, Tanzania at about 8 o'clock in the evening of the 20th November, 1967. The bird had flown against the window of a lighted room. There was a spot of blood at the base of its beak but it was otherwise unhurt. I kept it in a basket overnight and next morning, placed it on open ground and pointed it due north, believing at the time that this was the way it ought to have been going. The bird paused for a moment as if taking its bearings, leaped into the air, swung round and flew off due south with a a low, direct and fast flight.
