A new study of North American songbirds reveals an ecosystem falling out of balance.

Yet another new study illustrates the potentially deadly impact that climate change will pose for many migrating bird species.

This time around research into North American songbirds looked at how warmer springs will cause plants to grow either earlier or later than usual. It might be just a few days in either direction, but that’s enough to cause problems for nine out of 48 studied bird species, which researchers say will now have trouble finding the right insects to eat, impacting the birds’ ability to breed.

This follows research published last year which found that similar effects could be felt by hundreds of bird species across five continents.
