Buckley found that different birdsongs have different effects on our mental health.  Buckley reports that “Mental health benefits of birdsong differ between bird species. . . . Benefits of birdsong for mental health provide an economic argument for conservation of bird species, assemblages and habitats; but we need to quantify the benefits of bird diversity, and of rare relative to abundant bird species. . . .  the benefits of birdsong may depend on particular bird species, e.g. since songs bring memories or emotions. . . . birdsong is not a single homogeneous parameter.”

Hammoud and colleagues identified positive consequences of seeing or hearing birds.  They report that they “used the Urban Mind smartphone application to examine the impact of seeing or hearing birds on self-reported mental wellbeing in real-life contexts. . . . Everyday encounters with birdlife were associated with time-lasting improvements in mental wellbeing. These improvements were evident not only in healthy people but also in those with a diagnosis of depression, the most common mental illness across the world. . . . results . . .
