Sugar maple and birch bats must have a clear finish so that the grain can be inspected easily.
We found no significant differences in flight performance or echolocation behaviour between bats fed sugar water and bats fed ethanol, suggesting that wild frugivorous and nectarivorous phyllostomids tolerate ethanol at the concentration we studied.
Regular mice," she recounts early in the book, adding rats, turtles, ducklings, a baby bat, a vole, sugar gliders, rabbits, a cockatiel, a bulbul bird, an albino frog, snapping turtles and hamsters to the roster.
The public, especially persons in close contact with bats (guano collectors, sugar palm tree collectors, persons with bats roosting in their houses), should be educated about the risk for rabies transmission from bats and should be encouraged to participate in surveillance by shipping specimens from sick bats for laboratory diagnosis of rabies.
We predicted that bats fed ethanol would show impaired flight and echolocation behaviour compared to bats fed control sugar water, and that there would be behavioural differences among species.
Scientists wanted to see the tongue in action, so they used high-speed video to record the bats feeding on sugar water.
During preliminary trials, we determined that our sugar concentration stimulated bats to drink rapidly, and willingness to feed appeared to depend on the individual bat and not the feeding treatment.
Bats were fed either a sugar water control (44 g of table sugar in 500 ml of water), or 1.5% ethanol with sugar water (40% ethanol diluted in sugar water with the same concentration of sugar as the control).
We weighed each bat and orally fed it enough sugar water with ethanol to attain a BAC of 0.11 g 100 ml−1, or the equivalent volume of ethanol-free sugar water as a control.
Sugar maple and birch bats must have a clear finish so that the grain can be inspected easily, something that disappointed players who like bats that are all black.
Since bumblebees live in an ecological environment with higher nectar sugar concentrations than flower bats, bumblebees may be expected to have a better developed ability for concentration discrimination.
