304 Some Notes on the Brown- quilled Rock Dove. 
my second nest of young made me feel very sad, and, of 
course, was a real loss, since these birds command quite a 
good price. It only proves what I have pointed out before 
that nothing can replace the personal element. The bird-lover 
is born, not made, and no amount of willingness can compen- 
sate for a lack of that true understanding that is at once 
both as indispensable as it is necessary to the successful rear- 
ing of birds in an aviary. 1 had exactly the same experience 
with my last Zosterops — the circumstances were so identical 
that the similarity of result could hardly have been a 
coincidence. 
I had intended writing about my (ireen Cardinals (Gub- 
crnairix cristatits). but I feel that this must suffice for one 
mstalment. and, 1 must allow my readers a " breather " before 
inflicting a further literary effort on them, for the p/esonl 
at least. 
I will just epitomise one or two obvious ( onclusion;^ 
before writing Finis, and they are: — 
1. Do not be positive of the sex of your birds either on 
your own or other people's authority. 
2. If your Cardinals have not nested try turning them into 
a large aviary. 
3. Remember even many secdcaters rear the ir young 'iluio.-.t 
entirely on live-food. 
4. Do not send young birds away until thoroughly "on 
seed,"' and after they have been caged up for a week 
at least, to make sure they are taking their food. 
5. Don't count your chickens before they arc hatched — but 
don't count on them till long after that.

By the Marquis ob' Tavistock. 
As I believe I am the lirst aviculturist who has had 
the chance of keeping this rare Australian Dove in England, 
the following notes, though very incomplete, may be of sufficient 
interest for publication. Rather more than two years ago 9
