%X One of the suggested reasons for the decline of the endangered regent honeyeater, Xanthomyza phrygia, is a decrease in foraging efficiency and increase in competition for resources due to the loss, fragmentation and degradation of woodlands and other habitats in south-eastern Australia. This study investigated the general behaviour of regent honeyeaters over 26 months during breeding and non-breeding seasons at three distinct locations in northern New South Wales. At the three locations, regent honeyeaters spent, on average, 43&#8211;52% of total time foraging, 22&#8211;40% resting, 6&#8211;10% flying, and 1.8&#8211;2.9% involved in aggression. In the Bundarra&#8211;Barraba region, regent honeyeaters spent 24% of total time breeding. In 1994 in the Warrumbungle National Park, birds that fed primarily on nectar spent more time in aggressive acts than birds that fed mostly on lerp. In 1995 in the Bundarra&#8211;Barraba region, nectar-feeding birds spent significantly less time foraging and more time in aggressive acts than lerp-feeding birds. In 1994, regent honeyeaters at Howes Valley spent less time foraging and in aggression and greater time resting in the afternoon than at other times of the day. In 1996 in the Bundarra&#8211;Barraba region, birds spent the greatest amount of time in aggressive acts and the least amount of time resting in the morning compared with other times of the day. Non-breeding regent honeyeaters in the Bundarra&#8211;Barraba region spent more time foraging, less time resting and less time in aggression in 1995 than in 1996. Non-breeding birds, on average, chased other birds 12.5 times per hour compared with an average of 20 times for breeding birds. Regent honeyeaters displayed a behavioural repertoire and proportion of time in different activities that is typical of other honeyeaters. Overall, this study showed that regent honeyeaters are not consistently or frequently suffering from a lack of, or problems with access to, food.
