30 Nov 2011-5 Jan 2012:
Three road trips! Snowy explored to the
south on 1 Dec, then made a big swing east in
the middle of the month, and then went southwest
at the very end of the month. We can expect more wandering, especially
as the llanos habitat dries out as the dry
season progresses. The distance between the
farthest points on this map is 445 miles (716
km).
Skip ahead to late 2012. |
|
Jan 2012:
At the beginning of the month, Snowy
moved north about 50 miles. Except for a brief
sortie on the 9th and 10th, he didn't move much. |
|
1-29 Feb 2012:
Snowy settled down and didn't move much
in February. |
|
Feb 2012:
These are some of the locations for
Snowy. He's found a small river that seems to be
providing good fishing. This is the good news. |
|
Feb 2012:
Turns out what I thought was bad news is,
isn't bad news after all. All those strange
rectangular ponds looked like fish ponds to me,
and that, of course made me very nervous.
So, it turns out that these ponds are called "prestamos,"
which in Spanish (and Portuguese) means
"borrows." The road construction crews took dirt
from along the road to get the roads high enough
to stay dry in the rainy season when much of
these llanos flood. Most of them probably don't
have any sizable fish in them, but some, like
the ones where Snowy spent some time on this
image, are connected to streams or canals, so I
suspect there's some tasty Osprey food in some
of them.
Thanks to our Venezuelan colleague Daniella Deardem for
the info (and the picture below). My blood pressure just went down a few
points.
(Scroll down to see a photo of this habitat.)

Here's the Venezuelan llanos and part of one of
the "prestamos" ponds that had me fretting about
fish farm ponds.
|
|
March 2012:
Snowy mostly stayed home, but did make a
few one-hour forays south to the "prestamos"
along the road south out of La Guarandinga. |
|
April 2012:
Snowy mostly stayed near her current
winter HQ near La Guarandinga, but he did make
a 150 mi (240 km) roadtrip across the llanos to
the south. |
|
May 2012:
No road trips this month. |
|
May 2012:
Most of the month was spent along the
small river flowing just north of the thriving
metropolis of La Guarandinga. |
|
June 2012:
More of the same. |
|
July 2012: A few more forays east and west,
but he's still in a pretty restricted area,
which is good.
In July, he covered about 36 square miles (58 sq. km).
If we look at the core area, it was only 18
square miles (30 sq. km). While this is
encouraging (because the less these birds
travel, the lower their chance of running into
danger), it's still a lot more than some of our
old adults, some of which use just a couple of
square miles for their whole five months in
South America. |
|
Here's a close-up of one spot
that apparently is pretty fishy. It looks like a
swampy area. Also visible here are the "borrows"
- rectangular ponds created when the road was
constructed. |
|
August 2012: Pretty much a copy of the July
map, which is what we expect at this point. |
|
August 2012: Sometimes the tracks connecting
hourly locations tell a more informative story
than just the hourly fixes. We can see here that
Snowy has three bases of operation, with the
major one being the one up in the north. |
|
September 2012: Same old, same old. Makes
for boring maps, but boring also means safe. He
hasn't run into any problems here for most of a
year, so it looks like a good spot.
With a bit of luck, we'll see 7 more maps just like
this before heads north in April or May of 2013. |
|
October 2012: Same |
|
November 2012: Seems like he's spending a
bit more time closer to the road. |
|
December 2012: Snowy is definitely hunting
more along the road, probably taking advantage
of some of the "borrow ponds" as the surrounding
llanos dries up. |
|
1 Jan-10 March 2012: Two and a half more
months with very little foraging out away from
the road.
He should head north in the next month or two. |
