With regards to points 3 and 4, studies of migratory birds found dead in New Mexico last fall determined that the likely cause of death was long-term starvation. While the very early cold snap and snow storm didn’t help matters for the birds, smoke was not as much of an issue. The fires, on the other hand, are likely contributing to the issue of starvation by decimating habitat, including food sources, for these birds.

All the fires from last year that extended from Washington through California probably had an impact because these fires were burning in the Fall when our neotropical migrants were heading south. If any of us were having a hard time breathing with the amount of smoke in the air, what must it have been like for our feathered friends trying to breath as they passed through these impacted areas? Did we lose a higher than average number of neotropical migrants during the fires?
