Document Summary
Video monarch butterfly migration butterflies use their antenna to detect light if you paint their antenna with black paint, they won"t know what direction to fly in. Long-distance travel to a goal, often through unfamiliar territory. Difference between short and long distance will depend on species being studied. Large and small-scale navigation are typically studied independently, though they may involve overlapping mechanisms (mouritsen, 2006). Large scale navigation is often discussed in terms of homing and migration. Homing: the ability to return to a nest or burrow after displacement to a distant, often unfamiliar, site. Ex: carrier pigeons in 19th and early 20th century. pigeons are able to fly 100s of kilometers back to their home. Natal homing: returning to one"s birthplace to reproduce. Ex: green sea turtle hatches on one beach, immediately heads into water and spends life feeding elsewhere. Ex: humpback whale feeds in cooler northern waters, travel up to 25,000km every winter to warmer waters for reproduction.
