Chapter 10: Migration & Navigation Flashcards
Adult survival rate: 80-90% vs 50% vs 20-50%
Annual reproductive success: low vs moderate vs high
tropical vs migrant vs temperature resident
migrate according to local food availability
i.e.?
irruptive
i.e. snowy owl
ink with funnel and stars
Emlin w/ indigo buntings
exhausted birds grounded after long migratory route across water or desert
i.e.?
fallout
i.e. neotropic migrants (warblers)
Helmholtz coil
used to apply artificial magnetic field to homing pigeon
placed silk thread on eastern phoebe (returned to his house next year)
john james audubon
obligate partial migration (i.e.?)
some members of a population are inclined to migrate while others are not (i.e. robin)
migration due to limitations in number of organisms environment can hold/support (i.e. chickadee)
facultative partial migration (i.e.?)
some members of a population are inclined to migrate while others are not (i.e. robin)
obligate partial migration (i.e.?)
can find nests by smell
petrels and pigeons
obligatory annual migration
favored when resources in breeding area differ greatly season-to-season
