It took me about five of her trips to catch this female Orchard Oriole pausing outside her nest. I had first seen her dart up to the branch and then poof, she was gone. I watched this clump of Spanish Moss for awhile and saw it moving like someone was in it and finally saw a head peak out. The opening of the nest faces the limb with leaves.
Fortunately for me she was a creature of habit and flew the same pattern from the nest to a swampy area to gather grass and back, singing both ways alerting me to be ready.
On one of her trips she stopped for a look around before continuting on her way.
