56 EINAR LÖNNBERG, BTRDS. 



Circus macrourus (Gm.). 



Rchw. I, ]). 535. 



A comparatively very common bird round Nairobi in December and January in the 

 open pastnre lands or shambas. When marching northward I made similar observations 

 at Ju ja farm, and on the way to Punda Melia and Fort Hall. Even round Guaso Nyiri 

 this Harrier was seen, and an old grey male was shot on the northern side of that river 

 not much east of the crossing on the Marsabit road. Compared with females and young 

 birds such grey males were rather seldom seen. 



Circus aeruginosus (L.). 



Rchw. I, p. 539. 



A male specimen was shot at Punda Melia when it was hovering över the shambas 

 looking for prey. 



Astur tachiro unduliventer (Rupp.). 



Rchw. I, p. 553. 



A female specimen shot n /i near Escarpment station must be referred to this sub- 

 species to judge from the colour of the upper parts and the pure white, not barred under 

 tail-coverts. It was found in the cedar forest. 



Astur sphenurus (Rupp.). 

 Rchw. I, p. 557. 



A specimen was shot at Njoro in the thornbush country north of Guaso Nyiri 2G /2 

 1911. This place may be near the southern boundary line of the species in East Africa as 

 it is chiefly a North African bird, although found as well in the northwestern as north- 

 eastern parts of the continent. 



Nisus (= Accipiter) minullus intermedius (Erl.). 



Rchw. I, p. 501 & III, p. 818; Erl., J. f. Om. 1901, p. 173. 



A specimen of this Sparrowhawk shot in the forest-reserve at the Limuru-road near 

 Nairobi is as dark on the back as South African specimens f. i. from Natal. The sides of 

 the head are, however, much lighter than the crown, and that might be a better charac- 

 teristic than the general colour of the back, if it shall be possible to maintain this subspecies. 



T observed this bird in thick forest. 



Micronisus gabar (Daud.). 



Rchw. I, p. 565. 



In the acacia-steppe round Luazomela river south of Guaso Nyiri as well as in the 

 thornbush north of the same this little hawk was seen and shot. It appears to prey at 

 least partly on grasshoppers.
