The foldable "Ottenby" walk-in trap: a handy and efficient wader trap for expedition conditions.
Författare
Summary, in English
We describe the history, construction, and use of a portable walk-in wader trap (i.e., modified Ottenby trap) designed to be used in field expedition conditions. It is rectangular-shaped, 120 x 41 x 32 cm when operational, weighs between 1.5 and 2 kg (depending on materials used) and can be folded flat for easy transportation. It consists of several metal frames filled with fishing net, and has a netted roof attached by an elastic chord. Traps are placed either singly or in groups, with the optimal trapping situation occurring when birds are feeding along some kind of leading line such as the edge of a estuary, lake, or other water body. The trap is highly efficient for waders up to around 100 g, but is also suitable for ground-feeding passerines.
