awe-inspiring creatures to have walked
the earth through ruled the earth for
over 165 million years cellular luckily
depending on how you look at it
dinosaurs are wiped out after 6 mile
wide Meteor slammed into Earth or so we
thought it turns out that one type of
dinosaur was able to survive total
destruction birds it is a proven fact
that dinosaurs evolved in the birds
birds rodents would survive a
catastrophe so I doubt 75% of all life
on Earth but birds are being faced with
a new threat a threat that is a danger
to nearly all life on Earth us in recent
years you have driven many creatures to
extinction including some species of
bird you have destroyed their habitats
that’s the weight of their food sources
and released new predators especially
cats and now hunt them let’s rent these
dinosaurs for me and wiped out again
there are over a hundred and ninety
confirmed extinct birds majority being
driven to extinction because of humans
there so everyone knows about like a
dodo and some less talked about once
like the Great Auk there is one species
that had a very surprising fate when
European settlers first came to the
Americas they saw billions of birds
migrating so many they could blot out
the Sun these birds were called the
passenger pigeons as soon as people saw
how many there were I realized there
could be a nearly unlimited amount of
them and I think it’s seldom me and
feathers to get massive profits since
there’s so many of them even an amateur
hunter the chief done 6 in just one shot
thousands were killed in a single day
eventually the numbers began to decrease
but nobody noticed since there are so
many of them when scientists noticed
that their numbers are decreasing they
try to pass laws to protect them or
return the way because the government
did not think they could go extinct
alright by the 1890s the passenger
pigeon was nearly extinct in the wild
I’m Jordy living in zoos in 1914 the
last passenger pigeon named Martha died
in captivity the extinction of the
passenger pigeon is a loss but it is
also an important lesson
it shows that even the most numerous and
proliferate species still have this
threat of extinction looming our
them but not all birds have a lost there
are many endangered and endangered birds
that still exist that can still be saved
save them you know other populations are
decreasing the biggest reason birds are
dying is because of deforestation this
is because many birds use forests as
nesting grounds for their young there’s
no force there will be no babies
deforestation also impacts the amount of
food burst and fined because most
species from trees are trees that needs
trees to survive the problem is most
people can’t do much to stop
deforestation but there’s another huge
cause that anyone who owns a pet cat can
help stop some people like their pet
cats go outside and to roam around this
can be a very serious threat to
songbirds cats they’re able to come many
songbirds in a single year there’s so
many songbirds are killed by cats every
year I have a demonstration I have two
cups this one represents four billion
birds and this one represents the mouse
on birds killed by cats every year 3.5
billion birds are killed by cats every
year you can help lower the amount of
birds that are killed by cats and every
year like keeping cats indoors or
letting them outside but keeping them
under supervision even putting a bell on
her cat and all that songbirds know that
a calves approaching so they can get
away birds are the last dinosaurs on the
planet but sadly many of them have gone
extinct again the thing is both of these
extinctions were preventable the extinct
birds are gone forever but there is
still other and other endangered birds
that could use your help and by doing
something as small as putting a bell on
your cat you can stop some of the last
dinosaurs from disappearing forever
thank you [Applause]
