One a them went. repeatedly into a thick bed of Typha, 
always at the same spot, behaviour which the head keeper 
noticed too on the 29th. The inference was that the bird 
was feeding a sitting mate, or more probably newly-hatched 
young, on the nest. The reservoirs are fringed in places 
with broad dense beds of reeds and Typha angustifolia— 
admirable nesting-places for Grebes,—and, although the 
keepers by Lord Rothschild’s orders were on the look-out 
for nests, it is hardly a matter for surprise that none was 
seen, for the recesses of the reed-beds could only have been 
explored at the risk of disturbing the birds. 
“On the last day of June a pair and an anatetet 
bird were swimming in open water on the reservoir which 
the whole party had frequented during May. Even ata 
considerable distance one of this pair looked much more 
bulky and sat higher in the water than its mate, and I 
suspected that it was carrying young. ‘This suspicion was 
strengthened when its mate swam towards it with food in 
its mouth and passed the food to something on its back. 
With the telescope we could plainly see the heads of young 
ones protruding above the raised wings of the bulkier bird, 
but it was impossible to tell at the distance how many 
young there were. Once during the two hours we were at 
the place a single young one swam clear of the parent for a 
minute or two and then clambered up again over its tail. 
Except for a few brief intervals the other parent was con- 
stantly bringing food to the young, diving in the shallow 
water close to its mate. It stayed under water for only a 
few seconds at a time, and so achieved several journeys per 
minute; indeed, its industry and activity were astonishing 
compared with the more leisurely tactics of the Great 
Crested» Grebe when feeding young. Although I never 
ascertained how many young were hatched out by this 
pair—it is certain that there was more than one chick on ~ 
the back of the old bird on June 30th,—it may be that 
only one was reared, for in the latter part of July I could 
never detect more than one, with an old bird always in close — 
attendance. On August J1th, by which time it was. well
