In
the focus problem at the beginning of this chapter, a study was
described comparing the hatch ratios of wood duck nesting boxes.
Group I nesting boxes were well separated from each other and well
hidden by available brush. There were a total of 469 eggs in group
I boxes, of which a field count showed about 266 hatched. Group II
nesting boxes boxes were placed in highly visible locations and
grouped closely together. There were a total of 820 eggs in group
II boxes, of which a field count showed about 260 hatched.
