The Passage of the Pigeon Taylor Spruce
Major Upheavals Ice Age Meteor Impacts Dramatic climate changes Fire Tornados Storms Floods Erosion
Meteor ImpactForest Fire Activity list ways humans change habitat
Extinction Cause by man Fire Logging Erosion Damming rivers Introducing non-native species Pollution Wars
Clear cutting Floods
Ways Some Species Survive Emigration Adapt Adaptation
Do some species survive when habitats change? Emigration: When a species leave in search of new habitat. Some species stay and still survive they adapt to the changing habitat.
The Eggatuffs Millions of years ago many different animals roamed the planet. Some no longer live. Some die out because other animals ate their eggs, killing their offspring needed to start new population. Activity on Eggatuffs
What special adaption did the Eggatuff have that other animals didn’t? What would happen if Eggatuff eggs were soft? What if some eggs were soft and some were hard? Activity split into groups And work on Activity sheet 1.3A and 1.3B
Extinct Species Animals and plants become extinct for many different reasons, over hunting, introduction of exotic species. Miller Lake lamprey (1953)Blackfin cisco (1960) Silver trout (1930)Blue pike (1971) Relict leopard frog (1960)Labrador duck (1878) Laysan rail (1944)Passenger pigeon (1914) Greater kona finch (1896)Dusky seaside sparrow (1987) Pallid beach mouse (1946)Atlantic gray whale (1750) Great Plains Wolf (1926)California grizzly bear (1925) Sea mink (1890)Stellar’s sea cow (1768) Activity 3-sided display describes a species range in the world why they become extinct, physical description. Then write a species that was save from extinction and why?
Passenger Pigeon No one could believe that The passenger pigeon could become extinct Because there were so many of them.The hunter Killed many splintering their Big colonies. Last passenger pigeon Martha, died in Cincinnati Zoo in 1914
On a Monument to the Pigeon “Our grandfathers were less well-housed, well-fed, well clothed than we are. The strivings by which they bettered their lot are also those which deprived us of pigeons. Perhaps we now grieve because we are not sure, in our hearts, that we have gained by the exchange…. For one species to mourn the death of another is a new thing under the sun…. But we, who have lost our pigeons, mourn the loss. Had the funeral been ours, the pigeons would hardly have mourned us.”
