NATURAL HISTORY NOTES 
magazine article which I cut out recently. The article is 
entitled * Fear in Animals, ’ and we read that in the great forest 
fires they lose all fear of one another — elephants, snakes, lions, 
tigers, antelopes, flee side by side from the common enemy. 
There was also a full-page illustration of the flight, with a lion 
bounding majestically along accompanied by a trumpeting 
elephant, a tiger slouching through the undergrowth, with both 
deer and antelope bringing up the rear ! 
June 1. — On January 13 I remarked on an apparently 
old nest which I poked off a branch, when a fresh egg like a 
shrike’s fell to the ground. To-day I was again passing the 
tree, and turned aside to take a look into it. On the same 
branch was an almost identical old nest with a shrike (Lanius 
humeralis) sitting tight on four eggs. At every season of the 
year, as far as I can speak, I have seen adult shrike with newly- 
fledged nestling clamouring for food on the telegraph wires 
or fences, so they must breed all the year round. They cer- 
tainly have abundant thorns for their larders, and I have come 
across huge caterpillars impaled by them. 
June 3. — Being Empire Day, I cycled out in my own 
company to Ngong Forest, about ten miles from Nairobi. 
Though I collected a lot of insect life, there is little to report 
of interest. 
About the tree-tops were some magnificent swallowtails 
(PapiUo cenea) &c., and from 2 p.m. till 3.45 p.m. I walked 
up and down the forest path trying to catch them, as occasion- 
ally one would flash like a meteor into some sun-lit glade or 
zigzag along the path about six feet above one’s head. At 
a quarter to four I caught the first, and as I laid the net on the 
path and knelt to transfer it to a collecting envelope, a shadow 
fell upon me, and I realised that another swallowtail had 
paused in its flight to hover over me. This suggested an idea, 
and removing my beautiful prize from its envelope, I laid it 
with outspread wings on a near-by shrub. I had scarcely 
time to step back before seven or eight of these large butter- 
flies were fluttering round their dead comrade, and within five 
minutes I had captured four more. I tried the same bait 
at different spots, and always with the same result, though 
never more than two came at the same time.
