Birds of the World is a subscription-access database that aims to describe comprehensive life history information on birds.This includes: [1] Species accounts . Details on taxonomy, habitat, breeding, diet, and behaviors
It includes more than 33 million photographs, 1.2 million audio recordings, and over two hundred thousand videos [1] covering 96 percent of the world's bird species. [2] There are an ever-increasing numbers of insect, fish, frog, and mammal recordings. The Library is part of Cornell Lab of Ornithology of Cornell University.
The breeding habitats of these birds are marshes and other wet areas with dense low vegetation, and may also be found in other areas with dense shrub.
