BUTASTUB. HALIAETUS. 161 



Held up against the light, the shell is a sea-green, much of the 

 same hue as that of the eggs of A. vindhiana. 



The eggs vary from 1*75 to 2'0 inches iu length, and from 1'4 to 

 l'Q2 in breadth ; but the average of thirty-six eggs measured was 

 1-83 by 1-53 inch.

The Grey-breasted Buzzard-Eagle breeds throughout Pegu. 



Captain Feilden wrote from Thayetrnyo : " I only found it in 

 a long line of paddy-fields, extending many miles inland from 

 Thayetmyo, but much broken by patches of jungle and dotted with 

 large trees standing singly or two or three together in the middle 

 of fields. It breeds in March." 



The only nest he took was built on a thin branch of a single 

 high tree surrounded by dry rice-fields. The eggs are very like 

 those of Butastur teem a pale skim-milk blue, and comparatively 

 glossless, but with a very few tiny, pale brown, and purplish-brown 

 specks. One egg measured 1*85 inch in length by 1*3 in breadth ; 

 so that, to judge from this specimen, the eggs of this species are 

 somewhat narrower than those of B. teesa. 



Subsequently Mr. Gates found two nests of this species further 

 south in Pegu, near the town of Pegu itself. He writes : 



" March Ilth. Nest with two eggs; more would probably have 

 been laid. The nest was in a mango-orchard, in a small tree about 

 20 feet from the ground. It was composed of small sticks and 

 had no denned shape. Egg-lining green ; shell pale greenish 

 white, without gloss. Size of eggs 1'81 by 1*45 and 1*86 by 

 1-47. 



" March 3lst. Nest with two fresh eggs in a medium-sized 

 tree. The eggs are rather smaller than those I took before, mea- 

 suring 1*73 and 1*75 by 1/45 in breadth. Colour as before." 



An egg sent by Mr. Gates is a very broad regular oval, the shell 

 very smooth and compact, but with scarcely any appreciable gloss ; 

 when held up against the light a clear dark green. The colour is 

 white, with an extremely faint greenish -grey tinge. A few tiny 

 greenish spots are dotted about the large end of the egg, and as 

 usual the surface of the egg exhibits here and there a few pale 

 vello wish-brown stains.

Mr. H. C. Parker procured an egg of the White-bellied Sea- 

 Eagle on the 28th January, 1861, from a nest in a lofty tree near 

 YOL. in. 11
