of the Calcutta District. 63 



94. Aquila clanga. (Spotted Eaj^le.) 



One or more of these birds may generally be seen in the 

 vicinity of the larger jheels, and then remain in the district 

 all the year ; but there is a great addition to their numbers 

 in the cold season. 



95. Spizaetus limnaetus. (Changeable Hawk-Eagle.) 

 One of the commonest Eagles in the district ; universally 



distributed and resident. An old nest was found near 

 Sodepore, which the birds appeared to be repairing, in 

 March; both birds were in dark brown plumage; but 

 another, shot near the same place^ was in very pale plumage, 

 and pure white beneath^ marked with dark spots. 



96. Spilornis cheela. (Crested Serpent-Eagle. j 

 Common^ universally distributed^ and resident. Breeds 



during the hot season. 1 found a nest on May 10, 1891, 

 in a mango-tree — a large structure of sticks, many Avith the 

 leaves on, resembling a small nest of Pseudogyps bengalensis 

 — which contained one young bird, with the feathers on the 

 body only just beginning to grow, but with the crest ahxady 

 fully developed. Its eyes were very pale yellowish white. 

 It was very fierce, erecting its hood and biting savagely, 

 but did not attempt to use its claws, for its legs appeared to 

 be very delicate and hardly able to support the weight of 

 the bird. 



I once saw one attempt to carry off' a dead mongoose that 

 had been shot. 



97. Haliaetus leucogaster. (White-bellied Sea-Eagle.) 

 This species has been noticed on several occasions, usually 



in the larger jheels, but does not appear to be plentiful. 



98. Polioaetus ichthyaetus. (White-tailed Fishing- 

 Eagle.) 



Not uncommon in the neighbourhood of the larger jheels, 

 and resident. This species has a wild ringing cry, which 

 can be heard at a great distance. Also noticed at Mogra, E. I, 

 Railway, on the river there.
