At the US/Mexico Border

"Earlier today, I saw thousands streaming very high overhead in Del Rio, TX. I first noticed them about 4:00 pm. I've been seeing them for over an hour now. Amazing numbers. They are barely fluttering and streaming by very fast.

"They continued until sunset and maybe after but I think some stopped to roost. There were several that roosted in my neighbor's Hackberry tree. They were streaming very high, we had to use binoculars to see them and even with them there were some that were higher.

"We had received rain earlier in the day but it had stopped. The wind was blowing maybe 15 - 20 mph from the N N W.  They were moving rapidly across the sky and were barely fluttering their wings."
