  1. Use prescribed burning on savannas

    A small study in Minnesota, USA (Cox 1987), found that eastern bluebird Sialia sialis clutches in two nest boxes in an area that underwent prescribed burning both had 100% success (i.e. all eggs produced fledglings), compared with an average success of 93% for 23 nest boxes nearby.  Flame height was 1 m or less and did not reach the boxes at 1.2 and 1.4 m above ground.  Adult bluebirds left their boxes as the fire approached, returning when it had passed.
