Book Notices and Reviews. 79 
I trust the foregoing account of three of our members' 
aviaries, tliough taking largely catalogue form, will not have 
wearied my readers. If they only give a tithe of the interest I 
enjoyed while gathering mental and written notes, thej' will not 
have been penned in vain. 
Just on completing the above a note comes to hand frora 
Mr. Willford, giving a list of such of his birds as have already 
nests or nests and eggs. I quote same without reference to what I 
have already written. Red-iieaded Finches, Pectoral Quails and 
Cockateels, ail have young, while Gouldiau Finches, Long-tail 
Grassfinches, Diamond Sparrows, Green Cardinals, Redrump and 
Stanley Parrakeets are all busy incubating. The first lot of Green 
Singing Finche.s' eggs came to grief," but the}' have domed their 
nest and are sitting again. Mr. Willford has promised nesting 
notes for a near, probably next, issue, which should contain many 
interesting details, and I trust he will also amplify and correct 
where necessary the very disconnected account of his aviaries 
given herewith, and I hope Messrs. Mathias and Lewis will do 
the same.

The Birds of the British Isi.,ands. By Charles Stoiiliaiii, C.M.G., 
F.R.C.S., F.Z.S., with illusliatioiis by L. M. Medlaiid, F.Z.S. 
Parts IX., X., XII. and XIII. Royal Quarto. Grant Richards. 
Tlie excellence of the earlier numbers of this beautiful work is even 
more than maintained in the parts under review. Mr. Stonhani is an 
ornithologist of the painstaking type that leaves nothing of material 
interest nntouched : liis personal acquaintance with our British Birds might 
well be envied by tlie best of us; and moreover tlie pages of liis classic give 
overwhelming evidence of his industrious research. 
Part IX. deals with our three Harriers, the Buzzards, the Golden and 
Sea Eagles, the Goshawk and vSparrow-hawk, the Kite, the Honey-Buzzard 
(Pernis apivorus), and the Greenland and Peregrine Falcons. In conuecliou 
with the Marsh Harrier the interesting fact is noted that while the hen is 
incubating, the male bird feeds her by dropping food to her while lie liovers 
in the air. Montagu's Harrier has, it appears, a somewhat similar habit. 
When the male brings food the female rises to meet him, and catclies the 
food in the air as he drops it, returning at once to her nest to satisfy her 
liunger.
