Birds like egrets and herons rarely weigh more than a few pounds. Even the red-crowned crane, a five foot tall bird, caps out at about twenty pounds. An average nine-month-old human weighs that but is only a foot and a half tall. Flighted birds are crazy light.
Birds have optimized for minimum weight tho, so they can afford to only have 2 limbs supporting the entire body
Have you seen their legs though? They dont look sufficient at all, especially taller birds which stand in the water often have insanely thin legs
Keep in mind that most of the bird’s visible body volume is just fluff
