The effects of rodenticide residues deposited in eggs of Tyto alba to eggshell thickness

The deposition of anticoagulant residues in the eggs of barn owls, Tyto alba by assessing eggshell thickness were investigated in oil palm plantations. Three study plots were set aside; one plot each baited with chlorophacinone and bromadiolone, respectively and the third was left unbaited. Four...
