HAWAIIAN BIRDS. 31 



is not confined exclusively to omao but is shared by all the species 

 of Chasiempis. 



Abundant and widespread as is this thrush, practically nothing 

 is known of its nesting habits. The author feels assured that the 

 bird nests far up in the tall forest trees, and that only by the 

 merest accident will its nest be found. 



In March of 1899, while at Kaiwiki, I shot an adult io (Buteo 

 solitarius) ; and upon dissecting it I found in its stomach a small 

 fragment of egg-shell which I suspect was a portion of the egg of 

 an omao. It was of a light blue color sprinkled with minute 

 splashes of reddish brown. The size, as indicated by the frag- 

 ment, would well correspond to a bird the size of omao and, at 

 all events the egg both in size and color seemed to be essentially 

 Turdine in character. The mynah, the nest of which io some- 

 times robs, as is well known, lays a blue, unspotted egg. This 

 note is published for what it is worth and, unsatisfactory though 

 it is as evidence, I believe it affords a hint of the character of the 

 omao's egg.

Phseornis oahuensis Wilson. Oahu Thrush. 



Thanks to the diligent inquiry of Mr. Wilson we now know 

 that the island of Oahu formerly possessed a member of this fam- 

 ily of thrushes, and that in 1824 specimens of the bird were ob- 

 tained on the island by Bloxam, the naturalist of the "Blonde,"
