Policies should prioritize the preservation and restoration of large, unfragmented "core" areas, as these regions are essential for maintaining viable bird populations. Legal measures can also support the management of the landscape matrix, ensuring that it is conducive to the survival of native bird species. For example, discouraging the maintenance of open lawns on public and private properties can help preserve native vegetation and nesting structures (Marzluff and Ewing, 2001). Moreover, international and national policies should address the control of invasive species, which pose a significant threat to bird populations in fragmented habitats. Effective predator control measures can mitigate the impact of invasive mammalian predators on native bird communities (Morgan et al., 2022). Additionally, policies should promote the integration of urban parks into native habitat systems and encourage urban planners to consider the ecological function of fragments in their designs (Marzluff and Ewing, 2001). By implementing comprehensive legal and policy frameworks, governments can create a supportive environment for bird conservation and habitat restoration efforts. 8.3 Community involvement and education Community involvement and education are essential components of successful bird conservation strategies. Engaging local communities in conservation efforts can foster a sense of stewardship and responsibility for protecting bird habitats. Educational programs that raise awareness about the importance of habitat connectivity and the detrimental effects of fragmentation can empower communities to take action. For instance, community-based monitoring programs that measure bird fitness and population trends can provide valuable data for conservation planning (Marzluff and Ewing, 2001). Involving communities in habitat restoration projects can also enhance the effectiveness of these initiatives. Local knowledge and participation can help identify critical areas for restoration and ensure that conservation actions are culturally and socially appropriate. Additionally, community involvement can lead to the development of innovative solutions for habitat management, such as creating urban green spaces that mimic native habitats (Marzluff and Ewing, 2001). By fostering a collaborative approach to bird conservation, communities can play a vital role in preserving biodiversity and maintaining healthy ecosystems. 9 Concluding Remarks The systematic review of the effects of habitat fragmentation on bird behavior and extinction mechanisms reveals several critical insights. Fragmentation significantly impacts bird species, particularly in tropical regions where the disruption of biotic processes such as seed dispersal and insect herbivore control is mostsevere. Experimental studies in the Amazon have shown that fragmentation leads to the collapse of mixed-species flocks, with significant reductions in species richness and attendance. In the box-ironbark forests of central Victoria, Australia, predictions of species vulnerability to fragmentation were found to be unreliable, highlighting the complexity of species responses to habitat changes. Additionally, fragmentation impedes dispersal and gene flow, particularly in less mobile species, leading to reduced genetic connectivity. The non-random loss of species and the formation of distinct edge and interior communities further underscore the profound impact of fragmentation on avian community structure. Long-term studies in Tanzania have demonstrated that fragmentation leads to lower survival rates and population declines across multiple species. Moreover, fragmentation reduces avian breeding activity, which is a fundamental mechanism contributing to ecosystem decay. Finally, increased nest predation and parasitism in fragmented landscapes result in lower reproductive success, turning some populations into demographic sinks. Future research should focus on several key areas to better understand and mitigate the effects of habitat fragmentation on bird populations. First, there is a need for more comprehensive studies that integrate multiple species with varying mobilities and ecological traits to develop more accurate predictive models of species vulnerability. Longitudinal studies that track demographic rates over extended periods are essential to understand the long-term impacts of fragmentation on survival and reproduction. Additionally, research should investigate the
