I would say not all birds sing, mainly just song birds sing. Lots of other birds don’t sing either like crows, woodpeckers, jays, pelicans, eagles, hawks, owls, etc.
Note: I’m not any kind of bird expert, so it is possible some of the birds that I listed have a song-like call that I’m unfamiliar with or am forgetting about.
But it’s all about two things: attracting a mate and avoiding predators.
Some birds use sound for that. Other birds use visual displays, aerobatics, sheer viciousness, or other physical traits. Some use combinations of the above. Like everything else, what works will survive to be used by the next generation.

Just take a look at the shoebill stork. If this is singing than me dragging my nails across chalkboard should be qualified as opera
Yeah; crows have mating songs.
