Use of winter-burnt grassland by foraging bald ibises, G. calvus, and the abundance of invertebrates in winter-burnt grassland were investigated in relation to the time elapsed after burning in Natal high grassland. Bald ibises were recorded feeding in dormant, winter-burnt grassland from < 4 h after burning up to 35 days after burning. Insects and other potential prey items were significnatly more abundant 0-7 days than 14-37 days after burning; most specimens consisted of fire-killed arthropods. Live insects increased in abundance soon after the appearance of new growth 46-82 days after burning. Possible factors influencing the use of winter-burnt grassland by foraging bald ibises are discussed with emphasis on changes in the relative abundance of living and dead arthropods in relation to the time elapsed after burning.
