Disturb birds at roosts Bird Conservation

A before-and-after study in Bet She’an Valley, Israel (Nemtzov 2005), found that pygmy cormorants Phalacrocorax pygmeus relocated away from fish farms and bred successfully in nearby wetlands after harassment at all roosting sites in the valley using gas cannons and pyrotechnics in the winters of 1999/2000 and 2000/01. Between 1998 and 2004, number of cormorant nests in the area increased from 60 to 110 (peaking at around 155 in 2001).

 

Scare birds from fish farms Bird Conservation

A before-and-after study in northern Israel (Nemtzov 2005) found that pygmy cormorants Phalacrocorax pygmeus relocated away from colonies near fish farms during 1999-2002, following the use of gas cannons and pyrotechnics to scare birds before the start of nesting in winters between 1999-2000 and 2002-3. Between 1998 and 2004, the overall number of cormorant nests in the area increased from 60 to approximately 110 (reaching a high of approximately 155 in 2001), possibly due to greater reproductive success with lower levels of persecution following relocation.
