Methods<br />
Shooting. - Few have been the occasions where an<br />
air gun or an air rifle (Gamo brand) with calibre 4.5<br />
bullets was used, mostly for shooting isolated mynas<br />
which were avoiding or did not justify the use<br />
of traps. These air guns require a local license, and<br />
it is better to use them out of the general public view.<br />
Traps - Different types of traps that have been used<br />
in capturing mynas.<br />
• SRT - Small Round decoy Trap. Commercially<br />
made in Belgium 50 cm size with a central space<br />
for the decoy and 4 catching compartments<br />
around provided with a door release system activated<br />
by the caught bird. Is able to trap more than<br />
one myna per compartment. Weight: 5,2 Kg.<br />
• SDT - Small Decoy Trap. A hand made square or<br />
round trap, 70 cm size, with a central decoy compartment<br />
and 4 catching compartments dependent<br />
(*) Decoys used only one day.<br />
upon individuals tripping a door release for closing,<br />
each capable of catching one (or more) myna<br />
per compartment. Weight: 6 Kg.<br />
• LDT - Large Decoy hand made square Trap, 1.2<br />
m sides, with a central decoy compartment and<br />
12 catching compartments, each capable of catching<br />
between one and three mynas on each compartment.<br />
Weight: between 7 and 9 Kg.<br />
