EAST AFRICAN BIRD RINGING REPORT 1970-1971

By

G. C. BACKHURST

P.O. Box 29003, Kabete, Kenya

INTRODUCTION

No. 136

This report covers the period 1st July 1970 to 30th June 1971. The total number ofbirds ringed was 17S13 (see Table I), an increase of 3000 over the previous year's total(Backhurst 1971); however, 10630 Palearctic migrants of 61 species are included in thisfigure compared with only 6084 ringed during the previous year.

The full list of birds ringed is given in Table I where Palearctic migrants are printedin bold type; birds which are Ethiopian as well as Palearctic are printed in ordinary type.The nomenclature used follows the lists of C.M.N. White (references given in Backhurst1970) and as these lists are regarded as the standard for the Ethiopian Region, authors'names have been omitted. One map is included in this report showing the year's recoveriesoutside East Africa. Previous recoveries were shown on two maps in last year's report(Backhurst 1971).

SOME NOTES ON RINGING IN EAST AFRICA

Twenty-one ringers were operating in the three East African countries of Kenya,Uganda and Tanzania during the 1970-71 ringing year. Most ringers were in Kenyawhile very few were in the other two countries; a list of ringers is given on page 13.

This year's 19 Palearctic recoveries are most encouraging and should inspire thosewho specialize in Palearctic migrants to ring more of them. Some interesting recoveriesmay be mentioned: the female Ruff Philomachus pugnax No. B.4166 was ringed on lOthMay 1970 at Lake Nakuru, Kenya when it weighed 137g, some 49 per cent above themean winter weight (Pearson et al. 1970); however, in 1971 it was recovered near Nadymin the Soviet Union (over 6SoN., and 72°E.) on ISth April, i.e. three weeks earlier thanlOth May when, the year before, it had still been south of the equator. The EuropeanSwallow Hirundo rustica No. J. 37100 was the first East African-ringed bird to be controlledin the U.S.S.R., by Dr E. I. Gavrilov at the Chokpak Pass in Eastern Kazakhstan; inaddition, J. F. Reynolds controlled one of Dr Gavrilov's Swallows in Iringa. The Swallowcontinued to give the high recovery rate mentioned in last year's report (Backhurst 1971).

Pride of place for startling recoveries must go to the three non-hirundine Passerines(other than wagtails) which were recovered in the Middle East: the Kabete Reed WarblerAcrocephalus scirpaceus to Saudi Arabia, the Ng'iya Blackcap Sylvia atricapilla to Iranand the Mbale Redstart Phoenicurus phoenicurus to Iraq. The Redstart recovery was made

Pagel

exactly one month after it had been retrapped at the ringing site. Some ringing totals ofindividual species are also worthy of note: 900 Little Stints Calidris minuta (but still norecoveries), 818 Ruff, 188 Marsh Sandpipers Tringa stagnatilis, 622 Striped SwallowsHirundo abyssinica, 2770 European Swallows, 1029 Willow Warblers Phylloscopustrochilus, 202 Red-chested Sunbirds Nectarinia erythroceria and 355 Dark-cappedBulbuls Pycnonotus barbatus. Twelve Palearctic species were ringed for the first timeduring the year, these were (with number ringed in parentheses): Pallid Harrier Circusmacrourus (I), Spotted Crake Porzana porzana (I), Common Tern Sterna hirundo (I),Red-necked Phalarope Phalaropus lobams (2), Black-tailed Godwit Limosa limosa (I),Whimbrel Numenius phaeopus (I), European Cuckoo Cuculus canorus (I), European ScopsOwl Otus scops (I), European Night jar Caprimulgus europaeus (I), Pied FlycatcherFicedula hypoleuca (2), Chiffchaff Phylloscopus collybita (I), and White-throated Robinlraniagutturalis (3). The addition of these twelve birds has raised the number of Pale arcticsringed since 1960, when the scheme started, to 79 although only 61 species were ringedin the year under review. As a final numerical exercise it is interesting to abstract thosespecies whose grand totals top 1000; there are just ten: Little Stint, Ruff, Striped Swallow,European Swallow, African Sand Martin Riparia paludicola, European Sand MartinR. riparia, Yellow Wagtail Motacilla jlava, Willow Warbler, Yellow-backed WeaverPloceus melanocephalus and Dark-capped Bulbul.

More ringers are still needed in East Africa especially if they are experienced and,in this context, visiting ringers from overseas are eSpecially welcome but they are remindedthat the East African Scheme uses its own rings and, as the stocks held are not particularlylarge by European standards, those intending to visit East Mrica for ringing should contactthe writer as soon as their plans are finalized so that more rings can be ordered if necessary.

ACKNOWLEDGEMENTS

Ringers gratefully acknowledge the co-operation of the City Engineer, Nairobi forallowing them to operate at Kariobangi Sewage Works; the Director of the KenyaNational Parks for permission to ring at Lake Nakuru and in Tsavo National Parks;the Director of Veterinary Services, Kenya for permission to ring on certain land atKabete. The Society is also grateful to the Administrative Director of the NationalMuseum, Nairobi for allowing the Museum's address to appear on the rings.

I should like to thank the East Africa Natural History Society for the grant they madetowards the cost of sending Irie to the XV International Ornithological Congress in TheHague in September 1970.

Notes on Table 3I. The extent to which Palearctic migrants recur in their winter quarters (Ortstreue) has beendemonsttated only comparatively recently (see, for example, Moreau 1969 and in press, De Roo &Deheegher 1969, and Pearson 1972). The above table merely serves to show that the phenomenonoccurs between Eurasia and East Mrica; no quantitative conclusions should be drawn from thedata given, and, for this reason, no ringing totals are given in the table. This statement may needsome explanation: if Jackson (1938) had ringed his bread and cake-eating Yellow Wagtail in April1915 at Entebbe he would have achieved a 100 per cent return to winter quarters in October ofthat year when the bird came back. If, on the other hand he had managed to ring a single Swallowor Sand Martin caught while feeding in a flock near Lake Victoria it would have been exceedinglyunlikely that the ringed bird would have been detected or found in a subsequent year, althoughit is quite possible that the individual'Swallow or Sand Martin had returned to the same area.Thus the correct interpretation of Ortstreue data cannot be assessed without (a) full knowledge ofthe ringing picture at a given locality and (b) full knowledge of the trapping effort expended at thatlocality in subsequent seasons. It follows (giving an extreme example) that if 1000 migrants areringed at a locality one season from, say, December to March none will be retrapped the followingseason if no trapping is done there, giving a "nil" return to winter quarters. It is likely howeverthat if trapping is resumed the next season (i.e. two years after the 1000birds were ringed) a numberof first-season birds will be caught and this number will depend, apart from mortality and anynon-Ortstreue element, upon the trapping effort expended in the third season and upon the easewith which the particular birds can be caught. Any computation of percentages of returning birdsmust take into account the number of birds handled in the season in question, and this will includealso "same-season" retraps.

From circumstantial evidence it seems likely that most species of which individuals have beenretrapped in later seasonsare normally true to their winter quarters but, from the figures in Table 3and from personal knowledge as well, it is not yet possible to compare the extent of this fidelitybetween species; a final example will serve to illustrate the point: the single Willow Warbler listedin Table 3 was trapped in Napier Grass Pennisetum purpureum Schumach. at Kabete at the end ofDecember 1968. In the 1968-69 season only three Willow Warblers were caught at this site. Thefollowing season (1969-70) less effort was devoted to the area and no Willow Warblers were caught;however, in the 197°-71 season, despite a rather limited amount of netting effort (but neverthelessmore than in 1969-70)four Willow Warblers were caught including a 1968-69bird. It is consideredlikely that the small number of this species present in the Napier Grass at the times of netting werewinter residents and that the single retrap in 197°-71 suggests that Willow Warblers, albeit on avery small sample, are true to winter quarters. The reasons that only one Willow Warbler has everbeen retrapped in a subsequent season at the place of ringing are, in the writer's view, that eithermost are trapped on passage (i.e. not in their winter quarters), or that the majority of winteringbirds ringed have been ringed in areas where less trapping effort has been expended in later seasons.Detailed papers on Ortstreue are in the course of preparation.2. The table does not give a complete summary of birds retrapped in subsequent seasons: oneringer is known to have data on such birds but he is unwilling to part with them.
