Charles Spurgeon Commentary Jeremiah 9:10

"For the mountains will I take up a weeping and wailing, and for the pastures of the wilderness a lamentation, because they are burned up, so that none passeth through; neither can men hear the voice of the cattle; both the birds of the heavens and the beasts are fled, they are gone." — Jeremiah 9:10 (ASV)

The prophet pictures what the Chaldeans would do. They would not only destroy the cities, but they would even rob the hills of their cattle, and sweep the fields till there would be nothing left that people could gather.
