14. Behavior of bird / circumstances of observation (flying, feeding, resting; include and stress habits used in identification; relate events surrounding observation): Actively
fly-catching and resting on utility lines, live oaks, sycamores. Just prior to dusk, while watching the assemblage

interactions between these two. Just
occasionally sallying forth for aerial arthropods and giving intermittent
vocalizations. Both observed in flight
as well. |
