Well, it looks like he was right! It appears that more birds left last night than came into the state, although with strong westerly winds we should see some overshoots this morning along the coast, with these birds returning to shore in the morning hours. This will be a good day to ground truth because although migration was mediocre in density, it could mean good conditions at coastal locations due to the strong west winds.
