Floating structures are very acceptable to mallards. To encourage mallard use,
the goose structure design can be modified by placing a grassed wire roof over
the nest structure or by adding a cylinder nest structure to the platform. A partition
similar to that designed for a culvert structure (see "Mallards
- Culverts") can also be used to encourage mallard use. For floating
platform details, see "Canada Geese - Floating Structures",
and Figure 5.
