Caprimulgus is rooted in the Latin word “Capra,” meaning “goatsuckers,” advocating a myth that they used their giant mouths to suck milk from goats

These are medium-sized night birds with short legs, bills, and pointed wings. They are not big fans of high mountains or areas with high light intensity; instead, they prefer lightly forested zones with minimum interferences.

All nightjars spend their day sleeping and become active during the night. Their cryptic and soft plumage (grey and brown) helps them to blend and conceal along with the bark or leaves. They hunt flying insects during the night and have jarring cries. European nightjars clap back their wings (a phenomenon known as wing clapping) to display courtship, greeting, and defense. Nightjars should not be confused with owls, although they seem close relatives.
