4.1 HAND NETS 41 Catching bats M. Finnemore & PW. Richardson should be carefully positioned around the bat before it flies. This may prevent it from flying so that it can betaken by hand, but if it flies it will be caught in the net. Angling the net at 45–90° from the pole can increase the catch rate. In high roofs a second thin stick maybe used to touch the bat gently, causing it to fall into the net. Do not attempt to catch bats in flight. As soon as a bat is netted, the net frame should be rotated so that the bat is enclosed in loose netting and is unable to escape (Figure 4.3). Moving net Large kite-shaped hand-nets have been used for catching bats in flight. Unfortunately, bats are too easily killed or injured by this method for it to be recommended.
