What term describes the feeding behavior where Costa's Hummingbirds follow a regular route between favored flower patches?
Answer
Trap-lining
To maintain their incredibly high metabolism, Costa's Hummingbirds must visit numerous flowers in quick succession throughout the day. When they demonstrate a systematic pattern of visiting the same established sequence of favored flower patches repeatedly, this specialized foraging behavior is referred to by the specific term 'trap-lining.' This route strategy aids in their efficient calorie intake.
