tain the number of species that can be found in a certain 
area. In this case, it is not a very large one, so that the 
following total of approximately one hundred species 
would apear to be a fair average for this type of country. 
A careful check of their movements as far as the district 
is concerned has been kept over this period, and I hope 
these observations may be of interest for comparison with 
previous lists that have been made, for probably the 
ornithology of the district has changed considerably with 
the years. 
TYPE OF COUNTRY 
The range itself is open forest country, with a certain 
amount of undergrowth, consisting mostly of lantana, in 
the gullies which, in normal times, are generally dry, with 
a series of isolated pools in the lower levels. These be- 
come swollen with the heavy rains and flow directly into 
Enoggera and Ithaca Creeks. In continued dry weather 
conditions in the reserve become uncongenial for bird life, 
due to the drying up of this water supply which, to make 
matters worse, generally coincides with the periodical out- 
breaks of bush fires, so it is quite obvious that the 
presence of bird life is influenced to a great extent by the 
weather conditions. The surrounding country is sparsely 
settled and well watered with Enoggera and Ithaca 
Creeks, so that quite a number of birds are to be found 
along the watercourses and in the open paddocks and 
cultivated land adjoining them. 
CLASSIFICATION 
For the sake of convenience, I have adopted the some- 
what unscientific method of dividing the species into four 
groups. The first consists of those that are more or less 
permanent residents of the range. These are to be found 
at any time of the year, and have no definite migratory 
movements. A second group consists of local birds that 
make no definite migration but are noted a sufficient 
number of times to rule out any possibility of their 
presence being accidental. A third group consists of birds 
that are definitely known to be nomadic and migratory, 
while last but not least I have created a fourth group con- 
sisting of birds that are definitely strays and accidental 
to that area. 
PERMANENT RESIDENTS 
The Stubble Quail appears to be the only representa- 
tive of that order to be found in the reserve. He is not at 
any time too plentiful or fond of showing himself, but 
generally waits until you are almost upon him, whereupon
