Abstract

During the summer of 1995, for three days we studied the chick-rearing behaviour of a Striped Woodpecker (Picoides lignarius) pair in the temperate rainforest of southern Chile. The pair nested in a Luma apiculata stump in a riparian forest strip. The female made a higher contribution to the feeding of chicks (78% of all prey deliveries) than the male (22%). This trend was constant during all three days. The female was always successful at feeding nestlings, while the male failed in 57% of their attempts. The mean time interval between prey deliveries was 798 s. The prey delivered were exclusively insects, both larvae and imagoes. The most frequent insect preys given to chicks were beetles, with larvae and imagoes in similar proportion.
