Additional Notes o?i Nestiiig Habits of the Hawaiian Owl. 49 



The first nest taken (B. P. B. Mus. No. 1659, Fig. 3) I found 

 on January 29 in the top of a bush, eight feet from the ground, 

 where it was loosely, though daintily, attached to the small twigs 

 and leaves surrounding it. The outside measurements are 3 in. 

 across by 3.50 in. deep; inside it is 2 in. across by 1.50 in. deep 

 Externally it is composed of fine dry club moss and pulu fibre, 

 which is bound together and in place by spider webs ; inside there 

 are a few leaf skeletons and fine rootlets. The nest when taken 

 was not quite complete, but as it was on a steep mountain side in 

 a tangle of scrub, vines and ferns, I decided to take no chances 

 and accordingly colledled it, as well as the bird, which was near 

 at hand. The following day (January 30) Mr. Seale secured a 

 nest (B. P. B. Mus. No. 1660, Fig. 3) which contained two fresh 

 eggs, from a Kukui tree, some twenty feet from the ground. 

 With it he collected both parent birds, making the record most 

 complete and satisfa(ftory. The nest, like the one just described, 

 was loosely attached to the surrounding leaves. It is composed 

 of roots and moss, and lined inside with fine rootlets. The eggs 

 have a creamy white ground color, into which is worked the pale 

 brown under markings. Over these are sprinkled the redder brown 

 spots which form an ill-defined wreath about the larger end, 

 though they are thinly scattered all over the surface. Carefully 

 measured they are .80 X .58 in. and .78 X .60 in. respedlively. 

 This nest and eggs are plainly one of the best finds of the trip.

BY WM. ALANSON BRYAN. 



In The Auk (vol. xix, 1902, p. 299) I recorded our first infor- 

 mation concerning the nesting habits of the Pueo {Asio accipitrinus 

 sandviceiisis) . The note was based on a nest from Kalihi Valley, 

 Oahu, that was brought to my attention November 20, 1901. 

 When found it contained four young birds still ' 'in the first downy 

 plumage, the wing quills not having burst the capsules." I here
