Yes, we have them around here every year, and they are big birds. Maybe a 4 foot wingspan. I wish I could find out where they are nesting...........I also have not been able to get an image of one. But yours is good!
Thank you. From the limited research i have done, their nest would be very high. The adults feed on insects while inflight. They will also go for frogs, lizards to take to their young.
