In 2000 and 2002, the same pair of Peregrine Falcons occupied a nest box situated on the highest building within the Warsaw 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 majority of night feedings of nestlings was performed between 00:00 and 04:00. The average frequency of feedings was 1.5 events per night. It shows that night feedings can be considered an important part of feeding pattern during nestling period.
