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.”
