these two youngsters were born last spring

there's also a two year old male to help out with chores

his mother is nearly ready to give birth
as believers to each spring when that happens
things will get too crowded in the lab to move out ok

making the North America's largest rodent
the males and females young and old
all look pretty much alike and unlike any other creature
on earth but they're a bit like an oversized woodchuck
the borrowed spare parts from other animals therefore parts

a bond that may last a lifetime has forged in a few minutes
my
like any young couple the fossil from one another the mutually groom
and spend our side by side but even during the honeymoon
beavers are mostly business I'll
for homesteading beaver couple priority number one
is building a dam starting the project from scratch
the pair musters every skill engineer
woodcutter carpenter even stonemason from
they start by cutting brush handling it in a manner
on the stream on him
the pile stones on *** their hankering and placed

mud group
holes are patched with mine bulldozed into place
ok the basic
damn take Shane would lose a branch if
rocks %uh logs and debris
%uh ranged in a triangle as the water level rises
the Beavers that more layers making the damn
higher and wider them
the whole process takes about a month them
once they're happy with the water level the pair stops building
on water continues to see
through the day like spillway so the original stream
isn't really block is just too lazy below the dam
flows on as before him
am the 12-meter damn isn't alone has been renamed
girl the largest on record was twelve hundred meters long
but it does the trick
a brand new beaver pond starts to take shape
the first trees are cleared the stream is blocked
and the lamb lines
I'll with the single damn they've totally transform the landscape
on thick sheltering Willow Spring the line and one by one
other animals died to appear drawn in by this brand new wetlands
spoons mom
yet it's only the first damn
the beavers have no large and have been making do with simple burrows in the
back
but the pond itself is most crucial to their security
and they built it not a moment too soon on
alone emailed speak to wear said
she smells their presence on the back but she can't pinpoint where they are
ok the beaver sense of smell was as good as the ones
the young female sniffs out the danger mcclellan conspire
them
ok her tail slap
cracks like a whip %uh the alarm instantly center made
and any other beaver within earshot diving for the dams
it also lets the wharf no it's been detected
and probably jangles its nerves enough to send the predator
packing the young beavers have just passed the first big test in adulthood
the bill to summon them and a secure upon

its July in the Wyoming Rockies and the little

their mind is humming bird life and there's no *** construction to do
but a few things are demanding their attention them
the new kids for cleaning machines home
every month they have to gain about a kilogram

ok so Mom and Dad on food shuttling duty
they gather up the family favorites
called cotton Passman and Willow
then flowed branch after tasty branch
down the pond to the lodge the kids just wait for the delivery
and then squabble over who gets the bigger to wake
mom and dad don't deny themselves the lunch break either
they'll eat smaller twigs and leaves whole but mostly the lumbar
and the song coping with just lemme the new

which is why she built a nest right next door to the ***
quicken safe access to food is key to survival
that's true for birds big browsers
and beavers but to the Willow Pond beavers
that presents a challenge their food in building material rule on lap
but beavers are only safe in the water
to make things trickier
they chop down the closest trees years ago what's left as many yards from the
main part but going over land to get them
would be way too risky solving this puzzle calls for an ambitious hydraulic
engineering project can bring the trees to the water
so they have to bring the water to the trees
am the answer is a canal system
hmmm
their short mores out of the water have already warned ransom
little further excavation and the fill with water

there the tell-tale mark an older beaver pond
stretching as far as 230 meters into the surrounding forest
this way they always have a watery ski

I'm and it's definitely easier to move branches by floating
rather than dragging
the canals will pay off especially when the time comes to stockpile

there's no mistaking that time is drawing near
shorter days and a slight chill in the trees are subtle signs
