1. A study was made of the vertical distribution of breeding birds with reference to the vegetation. 2. The vegetation of the area was divided into definite vertical zones, and the birds were recorded in these zones by observing where they fed, sang, and escaped. 3. The conclusion was reached that there are definite vertical zones based on vegetational levels and that birds are distributed vertically in these zones.
