Its Just Their Nature. But Usually Its a Warning/Alert Call For "Un-Expected Intruder" Or They Just "Sing" On a Beatiful Day.
Birds can create a variety of sounds, including chirping, whistling, squawking, singing, and tweeting. Each bird species has its own unique vocalizations that they use for communication, mating, warning of danger, or defending their territory. Different birds can produce melodic songs, high-pitched calls, repetitive sounds, or even mimic other sounds in their environment.

Passerine birds are generally your smaller birds that perch on branches and sing songs by tweeting etc. Non-passerines are birds that do not perch and sing and tweet. For example, an eagle or an ostrich are both non-passerines as they do not chirp or tweet songs, where as things like sparrows and most birds you find in your backyard do tweet all day and perch. These are your passerines.
