Chestnut-sided Warbler Carrying Food

As climate change continues to escalate, many bird species are negativity affected. Consequently, it is important to research changes in ranges and abundances of bird species globally. This past summer, I worked as a field tech in Northern Ontario for the Ontario Breeding Bird Atlas documenting these changes. This research has important implications for conservation as well as understanding the ecological requirements for successful bird breeding. When I found this chestnut-sided warbler, she was carrying food back to her nest. Birds typically only do this when they're nesting in the area and need to feed their offspring! This provides important information to the atlas on chestnut-sided warbler breeding ranges.
