Peak migration continues as more and more ruby-throated hummingbirds arrive at the Gulf Coast. Observers, like Charlie from central Texas, are witnessing the surge:

"Waves of 10-20 rubythroats are coming at a time, about every 5-10 minutes apart. I saw at least 300-400+ this morning, from 7-10 a.m. Lots of adult males are mixed in, at least 1/3. The numbers are definitely increasing now, on tail end of a cool front from the north. Movement is to the east-southeast from my location, heading toward the Gulf of Mexico."
