The green warblers, or leaf warblers, are various-sized migratory birds belonging to the Phylloscopidae family. These bird species have green plumage, a dash of yellow on the face, and are usually subdued with greenish-grey or greenish-brown colors.

They also have two white with few black stripes on the wing bars, usually, only one of the wing bars is visible and prominent. They are agile and active and primarily feed on small insects hiding below the leaves.

As their habitat, these species use coniferous, deciduous, and mixed forests. The winters are spent by these warblers in the canopies of tall trees.

Their migration range for most warblers starts from parts of the United States to the Indian subcontinent and its surroundings. The breeding season takes place in the spring.

After the spawning process is over, it takes 12 days for the hatchlings to come out and their fledging range varies between eight and 10 days. Though the habitat of warblers is destroyed with each passing day, these birds have a fixed population and are therefore not too rare to find.

Green Warblers hop around forests and fly across open spaces. At dawn and dusk, the males hunt insects and sing to claim their respective territories. To protect their territory, they jab each other with their wings or peck their opponent on the head with their bills. They communicate with songs to attract females and chase away intruders.
