573. HALIAETUS LEUCOGASTER. 
(Vol. ii. p. 199.) 
M r Shoplaiid took one egg from a nest built in a high tree in the 
Hospital compound; Akyab^ on the 11th December ; it was of a chalky 
white colour and very rough in texture. 
615. DEMIEGRETTA SACRA. 
(Vol. ii. p. 250.) 
Mr. Shopland informs me that on the 19th May he had occasion to visit 
Oyster Island off the Arrakan coast, and that on this occasion he found 
eight or nine nests of the Blue Reef- Heron in a patch of thorny jungle 
near the centre of the island. The nests were from one to three feet from 
the ground, and were composed of dead sticks and leaf-stalks. No nest 
contained more than three eggs. The colour of the eggs was light green, 
and they measured on the average 1*76 by 1*28 inch. 
766. STERNA BERGII. 
(Vol. ii. p. 428.) 
Mr. Shopland found a considerable colony of these Terns breeding on 
Oyster Island in May. The nests were placed, or rather the eggs deposited, 
at intervals of about one foot, and in no instance were more than two eggs 
together. The sitting birds evinced great anxiety at Mr. Shopland^s approach, 
but were evidently very loth to leave their eggs ; they shuffled about and 
screeched, but they would not move. The reason for this extraordinary 
conduct was soon apparent ; the island was covered with hermit crabs, all 
ready, when opportunity offered, to seize upon the eggs. Mr. Shopland 
observed that the eggs upon this island were of two types, a larger and a 
smaller ; but he is certain that both belonged to S, bergii, for he shot many 
birds, and no other Tern was discovered at this spot. The largest egg 
measured 2*4 by 1*65 inch and the smallest 2 by 1'38.
