Some Owls in My Aviaries. 
My Rock Horned Owls have also made no attempt what- 
ever at nesting, but these birds call a good deal at night, and I 
think from this that they are more Hkely to start housekeeping 
than the others; but these aso are young birds. Their call is .l 
hoarse wheeze or grunt and not very loud. In fact none of my 
Owls are anything like as noisy as our British Owls, of which 
tour species are quite common in this district. The tawny and 
barn owls' voices are to be heard most nights in their singing 
season, but just at present they are silent, having, in all proba- 
bility, nests of hungry youngsters to cater for in the neigh- 
bouring plantations. 
My Spotted Eagle Owls are the only ones that have shown 
signs of nesting. The cock has on two or three occasions 
prepared a scrape, and has done his very best to get the hen to 
occupy it. It has been very amusing to watch his endeavours 
to get her to share his proposed nesting site, but only once or 
twice have I seen him entice her by the aid of a particularly 
choice tit-bit in the way of a mouse or small bird, to share it 
with him; but, even then, she has been unable to make up her 
mind to lay. Possibly the supply of really freshly killed meat 
has been insufficient. The call of these birds, which is often 
heard both by day and night, is a loud clear Hoo-uo, followed by 
a short Hoo about an octave lower, and it is much more musical 
than that of any of the other Owls that I have heard, although 
I used to think that the little burrowing owl's note was very 
pleasing when heard on the plains of Southern California. 
In the photos herewith the strong likeness between B. bengal- 
cnsis and B. ignavus will be noted, and the difference in size 
between the latter bird and B. falkland islaiidii can also be seen, 
as both birds were photoed on the same Sparrow Hawk.

Nesting in My Birdroom. 
By Mrs. M. Burgess, F.Z.S. 
Possibly a few notes of the doings of my birds in their 
indoor flights may be of some interest to my fellow members. 
Up to the present (June 9th) I have the following young on the 
wing, unless otherwise stated.
