194 BIRDS OF TASMANIA. 



Nest. A loosely constructed platform of sticks, placed in a tree 

 overhanging water or standing in a lagoon. 



Eggs. Clutch four to five; oval-roundish in shape; texture 

 coarse; surface slightly glossy; colour light bluish-green. Dimen- 

 sions in mm. of a small clutch: (1) 50 x 40, (2) 50 x 39.5, (3) 

 51 x 40. 



Breeding Season. September and March. 



Geographical Distribution. Tasmania and Australia in general. 



Observations. The Pacific Heron cannot be considered a 

 resident species, though doubtless a few individuals occasionally 

 remain the year through. During the autumn of 1892 several 

 districts in the north of Tasmania were suddenly visited by this 

 handsome species. Specimens were shot at Lake River, Stanley, 

 St. Mary's, and on the Kiver Tamar. During certain months it 

 is sparsely distributed on the North and East Coasts; doubtless 

 there are other localities as well. In addition to the mouths of 

 rivers, the Pacific Heron frequents swamps, in which place it 

 may be seen in company with other wading birds. Its food is 

 very similar to that of the Pacific Crane. 



The first record of this species in Tasmania was from Lake 

 Tiberias, March, 1876.
