SPRINGBUCK FROM SOUTH AFRICA 
This interesting antelope, once very common throughout a wide area in South Africa, is now very greatly reduced in numbers and in 
range. 
At the present rate at which it is being shot for sport this beautiful animal soon will become extinct.

prehensile tail grows out in a long feather, 
sidewise only. It is very lively, but nocturnal 
in its habits. We keep it at the Reptile House, 
in the Economic Rodent Collection. 
NOTABLE BIRDS 
By Ler S. Cranpay 
HILE arrivals during 1920 were not up 
to pre-war standards, they were far 
greater than in any other year since 
1914. Moreover, so many rare and _ striking 
species included, that the collection is 
richer at the present moment than ever before. 
We now have many birds that we never had 
hoped to possess, a considerabe number of 
were 
which have not previously been exhibited in 
zoological gardens. 
White-barred Ant-thrush.— The first bird 
of importance was purchased on July 16th, and 
was imported by Gustave Sebille, a well-known 
This White-barred

Ant-thrush (Thamnophilus doliatus), a small 
and inconspicuous creature in the eye of the pub- 
lic but nevertheless of great interest, for it is, 
without doubt, the first representative of this 
great neotropical family ever to reach a zoologi- 
cal garden. This bird is a female and a few 
months later, a male was acquired from the 
same source. Nothing previously was known of 
the habits and needs of ant-thrushes in captiv- 
ity but we have found them less delicate than 
most other purely insectivorous birds. Prob- 
ably more than 350 species of this family 
(Formicariidae) are known in tropical America. 
Cock-of-the-Rock.—On August 13th, we 
received from the Tropical Research Station, 
two fine male Cocks-of-the-Rock (Rupicola rupi- 
cola). Since the bird sent to us in August, 1919, 
was still thriving, we decided to risk two of 
them together in a large cage. The birds quar- 
reled at first but finally settled down and now
