Patti Brent asked about latest trends in how birds are moving along on their migrations routes.

I don't know if I've seen them address how wildfires, smoke, etc., might impact the birds' movements, but the Cornell Lab of Ornithology publishes their "Bird Cast":



BirdCast will allow, for the first time, real-time predictions of bird migrations: when they migrate, where they migrate, and how far they will be flying.

Knowledge of migratory behavior will aid conservation on the ground by informing decisions for placement of wind turbines and identifying nights on which lighting of tall buildings could be reduced to prevent the deaths of millions of birds. Accurate migration models also have broader application, allowing researchers to understand behavioral aspects of migration, how migration timing and pathways respond to changing climate, and whether linkages exist between variation in migration timing and subsequent changes in population size."
Hope this helps,
