We're seeing the graceful Swallowtail Kite most days now.
The favorite feeding field is one open to their acrobatic feeding practise and bordered by trees.
If the bugs in the field run out ~ they cruise low over the rees for different fare.
Here's a heavy duty paper on the Swallowtail and what it faces to survive. http://www.bio.georgiasouthern.edu/bio-home/Chandler/Zimmerman.pdf
