“…Based on observations, the best times to observe these two species are dusk and dawn. Tyto alba, a large owl, is often found nesting in buildings, cliffs, and caves (Olsen et al 2020;Saufi et al 2020). At the study site, these birds often approach settlements or perch on trees near rice fields when hunting for rats.…”

The development of avitourism in villages around the conservation area still needs optimal support to increase welfare and reduce illegal practices like bird hunting. Birds are wild animals that play an essential role in the ecosystem. One of the efforts that have been developed in the buffer village to improve the welfare community and the conservation of birds is avitourism. This study aimed to analyze birds that have the potential as objects and attractions in avitourism. The bird species recorded were 82 species from 39 families. The results of key informants’ perception analysis revealed that 55 bird species (67.07%) have the potential as objects and attractions of avitourism, showing the nocturnal birds, top 50 birds of Way Kambas National Park, and parrot species as the top classification (> 75%). The colorful, raptor, and protected criteria are second with the favorite classification (51-75%). Endemic and migrant criteria are in the third position with the impressive classification (25-50%), and the songbird criteria are the lowest with the interesting classification (< 25%). The existence of birds that have the potential as objects and attraction of avitourism in the villages around Way Kambas National Park indicates that areas can be used in locations for avitourism, including bird photography, to improve welfare.

“…As reviewed by Olsen et al (2020), the Asian-Australasian populations of the global Barn Owl Tyto [alba] complex should, on DNA evidence, be known as Tyto javanica, with the Australian population as subspecies delicatula. In Australia, as elsewhere globally where prey populations permit, members of the complex usually specialise on small terrestrial mammals, although their diet can be diverse (e.g.…”

The diet of the Eastern Barn Owl Tyto javanica was investigated by examination of two samples of pellets (n = 11 and 39), pellet debris and prey remains from: (1) an occupied nest with fledgling in May 2009, and (2) an Owl’s winter roost in August 2009 near Tamworth in the grain belt of New South Wales. The breeding diet consisted, by number, of 91% mammals (90% rodents, including 87% House Mice Mus musculus) and 9% common farmland birds (n = 116 food items). The winter diet consisted of 99% House Mice and 1% bird (n = 188 food items). The fledgling Owl was killed when it failed to flush from its nest hollow as the tree was being felled, during approved clearing of the now Critically Endangered White Box–Yellow Box–Blakely’s Red Gum Grassy Woodland and Derived Native Grassland. Given the dependence of the Barn Owl on House Mice, and the ongoing clearing of hollow trees, we note the potential for (a) secondary poisoning of owls by rodenticides, especially during plagues of the invasive House Mouse in the grain belt, and (b) the Barn Owl’s long-term decline in abundance in New South Wales.
