Trajectory analyses show that these behaviors increase migration distances by 40% and decrease the degree of drift from seasonally optimal directions. These flight behaviors match the sophistication of those seen in migrant birds and help explain how high-flying insects migrate successfully between ...
Both modes have evolved as compromise adaptations between the strenuous and conflicting constraints imposed by physiology and mechanics on flying birds. Bounding in birds has been accompanied by reduction in size and widening of adaptability to trophic conditions, while undulating permits larger birds to...

Fall migratory monarchs are characterized by two primary adaptations that enable their annual migration: reproductive diapause and migratory flight behavior. While the termination of reproductive diapause is known to involve juvenile hormone (JH) in monarchs,27,28 transitions between migratory behavioral sta...

Birds on migration normally switch between flight stages and periods of stopover where fuel stores are replenished. How migratory birds divide their time between flight and stopover is still not well known. Shortterm recoveries of passerine birds ringed in Sweden were analysed to investigate how far...
(Table2). Notably, although the insect–specific literature we inspected featured flight and migration gene candidates from an array of taxa and genetic approaches (Table S8), this represents only a partial survey (e.g., [101,102,103,104,105]). A comprehensive assessment, including analyses ...
Birds conducted long anticlockwise looping trips, on average lasting 20.4 days and covering 10 741 km. They reached a region in the southeastern Pacific Ocean where prey search behaviour was concentrated, typically about 3400 km west of the colony. Outbound and return journeys appeared to broadly ...
northropi is suggested by its allegedly short wings and, apparently mirroring the condition in modern flightless birds, by being considerably larger than its volant counterparts [25]. All three of the studies discussed above share common comparisons between pterosaurs and ...
