Art. 2. 
It shall be forbidden, at any season and in any manner 
whatsoever, to steal nests and eggs, to take or destroy 
nestlings. 
The import of these nests, eggs and nestlings, their trans- 
port, the colportage of the same, their putting up to sale, 
their sale and purchase shall be prohibited. 
This prohibition does not concern nests built by birds in 
dwelling-houses, or any kinds of buildings, on the same or 
in the interior of court-yards, which may be destroyed by 
owners, occupiers or any person authorised by the same. 
[Further the enactments of the present Clause may be con- 
sidered invalid in the case of the eggs of lapwings and 
gulls]} 
Art. 3. 
The construction and employment of traps, cages, nets, 
nooses, lime-twigs or any other kind of instruments used for 
the purpose of rendering easy the wholesale capture or de- 
struction of birds, shall be forbidden. 
Art. 4. 
In case the high contracting parties should not be in a 
position to enforce the prohibitions included in the preceding 
clause at once and in their entirety, they may mitigate the 
severity of the said prohibitions as required, but engage to 
restrict the use of methods, weapons and instruments of 
capture and killing in such a manner that the protective 
measures contained in Art. 3 may be carried into effect 
gradatim.
