Travels so far: 14 Sep-3 Nov 09. Signal lost. Transmitter recovered
(sort of).
We lost Bea's signal on 3 Nov in the middle of
Venezuela. This is one that we have to put into the "unknown" category.
She wasn't in an area with a lot of human activity, and seemed to be
doing fine. It could be a bad transmitter (another of this year's batch
failed and then restarted, so this is a possibility), but lots of other
explanations are probably more likely.
After never having been more that 2 miles
from her nest, Bea crossed 1,200 miles of open Atlantic Ocean in 43
hours. She landed on Cat Island in the Bahamas a few hours before dawn
on the 16th.
She blasted through the Bahamas, Cuba, and Hispaniola,
arriving in Venezuela only 10 days after leaving home.
Bea moved east across Venezuela and has settled down at
a series of reservoirs in north-central Venezuela.
She moved south of the Orinoco, where we lost her
signal on 3 November in the state of Bolivar. A month later we got a
signal and now know that the transmitter has been recovered from her
body.
Scroll down for details on her travels.

5-8 Aug 09. Bea's nest, on the west shore of Cape Pogue Bay, was one
13 active nests on Chappaquiddick Island in 2009 (the off-white donuts).
Ospreys love to fish in shallow waters, so Chappy was clearly designed
with them in mind. Cape Pogue, Katama Bay, and Poucha Pond all provide
ideal fishing conditions. |
|
5-8 Aug 09. Bea was one of two young fledged
from this productive nest. She isn't moving far from the nest yet. |
|
8-24 Aug 09. Bea is exploring a bit, having
ventured at least once over to Edgartown. |
|
25 Aug-7 Sep 09. Bea and Caley are vying for
the Couch-Potato-of-the-year award. The human residents of "Chappy" are
notoriously loathe to leave their small island, but I didn't know the
affliction crossed species lines. These are all the locations for over 2
weeks. Caley has ventured afield some, but Bea really never has.
It's quite unusual to have these two birds staying so
close to their nests when one of their "classmates" is already in the
Bahamas, Hix is in Maine, and Buck is hundreds of miles and 5 state
lines from his nest.
Every year brings its surprises. |
|
7-14 Sep 09. Spurred by shortening day length
and a stong NE wind, Bea made an aborted start to migration on the 13th,
apparently, but changed her mind. Maybe she forgot something? That was
the first time she was more than 2 miles from her nest in her life. On
the 14th she took off, this time for real.
43 hours later.... |
|
14-16 Sep 09. Looking south, we see Bea's trip
across this corner of the Atlantic. She covered 1,212 mi. (1,951 km) in
43 hours, averaging 28 mph (45 kph). |
|
16 Sep 09. (Back to looking north) Bea arrived
on Cat Island in the Bahamas around 04:00. About 11:00 she was off
again. Our last signal for the day was on Rum Cay (I thought Bea and I
had something in common). My guess is that she kept on going. We'll find
out in 3 days. I suspect she'll be on Hispaniola--or beyond--by then. |
|
16 Sep 09. Couldn't resist including this--Bea
touched down on Cat Island on an airport runway! |
|
16-21 Sep 09. Bea made
short work of the rest of the Greater Antilles. Her only concerted rest
of any sort was on Acklins Island, where it looks like she spent some
time fishing. She left there at noon on the 17th.
On the 21st she was in the eastern D.R., making us
nervous. After losing four out of four young Ospreys that tried to
overwinter in this half of Hispaniola, we're a bit gun shy and really
like to see our birds head for South America. |
|
21-23 Sep 09. Bea buzzed across the Caribbean,
leaving the D.R. at 11:00 local time on the 22nd. She made landfall on
Aruba, but kept right on flying, spending little time there, and finally
roosting in Venezuela, just east of the Gulf of Venezuela. |
|
23 Sep-18 Oct 09. Pretty standard stuff here,
moving east about 450 miles (724 km) across northern Venezuela before
changing course for a more southerly route. |
|
28 Sep-18 Oct 09. (Maybe leopards can't change
their spots, but my Ospreys can--she needed a new color to show up on
this map.) Bea seemed to be really settled in at a couple of small ponds
north of the Orinoco, but after almost three weeks she pulled out of
there and meandered south.
These are the movements of a bird that is done with
migration and is just looking for a really good fishing hole.
Of course when I make a statement like that, the bird
in question usually moves about 300 miles due south the next day. Could
do, but I'd need pretty good odds to take that bet.
Taking her 28 Sep-16 Oct area as the end of migration,
she covered 3,151 miles (5,071 km) in 16 days of non-stop migration. She
averaged 197 miles/day (317 Km/day). |
|
18 Oct-3 Nov 09. Bea
pushed east and south for two more days and then settled down along a
small, forested river that feeds into the Orinoco not far to the north.
She was there for 2 weeks before going off the air.
|
|
28 Oct-3 Nov 09. These are the last locations
for Bea. She was concentrating her hunting efforts along this narrow
forest river, just west of an area of extensive clearing.
As the transmissions ceased abruptly, we don't know
what happened to her. She's in a forested area, so if she died there,
the solar panels are unlikely to recharge the batteries in the
transmitter.
We'll keep hoping this is a malfunctioning transmitter
(like Isabel's), but until we find out to the contrary, we have to
assume she died of unknown causes. |
|
3 Dec 09. Imagine our
surprise when, on December 3rd, a month after the last signal from Bea's
transmitter deep in the state of Bolivar, Venezuela, we got two signals
from Ciudad Bolivar, the capital of the state. This had all the
appearances of a transmitter in the hands of a human. Shortly
thereafter, I got an email from the manufacturer of our transmitters,
forwarding an email they had just received from a Venezuelan who had
seen the transmitter and tracked down an email address for Microwave
Telemetry to inquire about it.
Once again, I enlisted the help of our colleague Adrian
Naveda-Rodrigues (see Isabel's maps for more on Adrian), who contacted
the people involved and has pieced together the following story. |
Bea's last signals came from an Indigenous Reserve in the state of
Bolivar. A pilot who flies back and forth between Ciudad Bolivar and the
reservation was flying the wife of a rancher from
the reservation to the capital, where the rancher maintains a house in
the city. Somehow the pilot, Idelmaro, saw the transmitter and, his
curiosity piqued, wrote down the name of the manufacturer, before
returning the transmitter. The woman told Idelmaro that they had found
the Osprey dead on the ground and recovered the transmitter and band
from it. Almost certainly, the smoke was still rising from the barrel of
the rifle they used to shoot the bird when they "found it on the
ground."
The woman was reluctant to return the transmitter,
probably afraid of legal repercussions. Adrian got in touch with
Idelmaro and somehow (details here aren't clear) the transmitter is now
in the hands of a Colonel in the Venezuelan National Guard, who
apparently is trying to figure out what sort of spy device the
transmitter is and how the Americans co-opted an Osprey to do their
nefarious work.
We're still awaiting word from Adrian, who is trying to
get the transmitter back for us. |
