Resting Behaviour of Parrots Loriculus galgulus

Abstract

This study analysed the preferences of perch size and position in the aviary in a group of 6 lorikeets (Loriculus galgulus). We monitored the presence of the lorikeets in four diff erent locations in the aviaryon the original perches, fl oor, wire mesh and experimental perches. The perch preferences were tested using 3 identical experimental perches, each of which consisted of 5 segments diff ering in diameter -ø 1 cm (circumference = 3.14 cm), ø 2 cm (circumference = 6.28 cm), ø 3 cm (circumference = 9.42 cm), ø 4 cm (circumference = 12.56 cm) and ø 5 cm (circumference = 15.7 cm). The distance between the 3 rd and 4 th toe was measured in all birds (it averaged in 2.4 cm) in order to assess to what extent the birds can enclose the perch with their toes. The observation continued for 35 consecutive days in a private aviary in the group of 4 males and 2 females of the same species. The images were captured in 10-minute intervals by a video-recording device. The number of images mapping the presence of the six birds totalled in 17898. Out of this number, the lories were 10453 times indoors (out of sight) and 7445 times in the outdoor fl y, which was monitored. They spent most of the time resting on the original perches (3067x) and totally ignored the fl oor (1x). They preferred perches (5102x) to wire mesh (2342x). All the diff erences were highly signifi cant. The favourite perch diameter was 2 cm (537x) and the least popular was the perch 5 cm thick (148x); the diff erence was also highly signifi cant. The analysis of the obtained data revealed that the lorikeets preferred sections A (788x) and E (600x) in the aviary, which means they spent most of the time along the walls. The diff erences among all the observed sections were highly signifi cant.

“…In recorded locations, it perches on banana trunks to collect nesting material (Fig. 7) other than leaves, bark, and wood chips (Andrysek et al 2014;Zhen 2020). Both birds often perform daily activities in the yard in the morning, such as foraging, perching, and singing.…”
