Use repellents on baits for predator control Bird Conservation

A replicated, randomised and controlled experiment on Tiritiri Matangi Island, North Island, New Zealand in June 2000 (Day et al. 2003) found that wild North Island robins Petroica australis longipes pecked significantly less at dough baits treated  with (either sprayed with or dipped in) a combination of green dye, pulegone and Avex™ (two avian repellents) than at control baits containing green dye and cinnamon. In addition, rate of pecking at treated baits declined over time (sprayed baits:  5 pecks on first day, 4 on second day, 2 on third day vs. 9.5, 10 and 9.5 pecks for control baits, n = 17 birds; dipped baits: 1.5 pecks on first day, 0.5 pecks on second, 0.25 on third, zero pecks on fourth vs. 6, 5, 3 and 3.25 for control baits, n = 21 birds).
