flap
straight descend,
level
264° - 097° 2.7 m/s - yes - Butterfly started at 4 m, glided down to 0.5 m, and started flapping.  A P. sennae was seen. Swifts were foraging overhead.  No D. plexippus were seen foraging during a check of flowers.
439 D. plexippus 3:36 100 m flap,
soar
straight,
circle
climb 273° - - - - yes - Butterfly started at 3 m, flapped up and encountered a thermal, it circled and soared and climbed to 100 m.  The D. plexippus passed through a huge flock of foraging swifts during it's soaring climb and was ignored.
440 D. plexippus 3:37 - glide straight descend 225° - 173° 2.0 m/s - yes - I missed altitude data.  The thermal had drifted too far downwind for detailed inspection but swifts could still be seen foraging in its lower section.

296° - 157° 2.0 m/s - yes - Butterfly started at 10 m, flapped upward and found a thermal.  The migrant gained altitude while soaring in circles, then left the thermal and glided down to another thermal where it circled and soared up to 60 m.  A swift was seen foraging.
