Median audiograms for 48 species of birds. Birds hear best at frequencies between 1 - 5 kHz,
with hearing most sensitive at about 2 - 3 kHz. In general, owls (Strigiformes) can detect softer sounds
than other birds over the entire range of frequencies. dBSPL is a measurement of sound pressure level in decibels,
where 0 dBSPL is the reference to the threshold of hearing for a typical person (Figure from: Dooling 2002).
