Abstract
The feeding response of feral rock pigeons (Columba livia) to wheat (Triticum aestivum) and barley (Hordeum vulgare) seed treated with the fungicide "Maneb" (manganese ethylene-bisdithiocarbamate) was assessed under aviary conditions. Bird preferences for dry or moist seed were also recorded. In all cases, non-treated (49.14 g birdE1 dayE1) rather than treated seed (32.97 g birdE1 dayE1) was selected, and wheat rather than barley (48.16 compared to 33.95 g birdE1 dayE1 respectively). Dry seed was consumed in preference to moist seed (47.53 g birdE1 dayE1 compared to 15.08 g birdE1 dayE1) a preference noted both when treated and non-treated seed was consumed. The birds fed exclusively on treated seed showed a reduction in body weight; no significant differences were recorded in those fed either untreated or mixed seed. Water consumption was three times greater in pigeons fed exclusively on treated seed.Downloads
