摘要

In 2000 and 2002, the same pair of Peregrine Falcons occupied a nest box situated on the highest building within the city centre. The nest box was monitored with a video camera and an infrared lamp. Records collected between 20:00 and 4:00 (DST) during the nestling stage (after the first chick hatching to fledging the last one) were used for analysis. Data from 34 nights in 2000 and 21 nights in 2002 were analysed. The average share of female was about 50% but time spent by the adults within the nest changed as the breeding season progressed. Late in the season parents spent only several minutes on nest.
