2013 Southern Cross Peregrine
Thanks to the kind and generous support of the
Falcon Research Group members, we are continuing the project in South
America for another year.
The FRG volunteer team will be arriving once
again in Santiago in late February to rendezvous with our friends in Chile
and head for the coastal city of Valparaiso to meet the container carrying
our two research vehicles to that Port.
We plan to spend the following three weeks in
Chile. During the first segment of the study, we will be concentrating on
capturing and satellite tagging two more adult female Peregrine Falcons with
solar powered, GPS-enabled Microwave Telemetry transmitters. We are happy to
report that the units weigh a third less this year, only 22 grams.
We’ll be working the dune field at Putu once
again, revisiting the site of the 2010 tsunami and seeing our friends there.
If there are not two new birds there, we’ll continue south until we find
others. Chiloe has been mentioned.
After this goal is accomplished, the team will
return to the US for three weeks.
Then, for the first time ever, two of us
(Anderson/Vanderveen) will return to Putu in the first week of April to
await the northbound departure of the two newly tagged falcons. We hope to
also be joined by Christian Gonzalez, SCPP team member and leading authority
on peregrines in Chile.
The falcons generally began migrating north
between 7-14 April and so will we. Our objective is to travel with them as
they migrate through the Atacama Desert of Chile and Peru and try to stay
with them through the tropical forests of Ecuador.
Our main objective is to learn more about the
conditions and habitats they experience as they fly north each day. We now
know quite a bit about their routes, departure dates, distance travelled per
day and roosting locations but we also want to learn more about the actual
conditions they encounter during these epic flights.
We are hoping that Island Girl will also be
joining us somewhere along the route, i.e. if her transmitter lasts for
another record-breaking year.
Since no one has ever attempted this before,
we cannot predict exactly what is going to happen. When we say “follow the
falcons”, we anticipate that we will closely approximate their route as much
as possible. What this means is anyone’s guess.
Will we be able to observe either falcon?
Probably not but that is what we will try to do. We are going to be in touch
with Don McCall at our “home base” in Seattle by satellite phone. So we will
usually have three GPS locations per day (1000, 1600 and 2200), including
roost sites. We’ll visit these spots as often as we can but it is likely
that the birds will have left before we can get there. There is always a
time delay in the transmission of these signals, sometimes substantially
longer than others.
However, we have one new advantage this year.
When we capture a bird, we will also be attaching a small 3 gram VHS
transmitter to a single tail feather. This feather will ultimately be molted
during the summer so they only last three months. With this tiny radio, and
using handheld directional antennas, we can receive constant directional
signals whenever we are close to a bird and within its line of sight. This
will help us home in on their locations quite well. Supplementing the data
from the satellite transmitter, we should be able to stay fairly close to a
Now we’ll see how reality enters
The ultimate, of course, would be to actually
see the bird, perhaps even witness a successful hunt, allowing us to
document her prey. Keep in mind that this is extremely unlikely to happen,
but we can dream.
When we finally arrive in Ecuador, we’ll be
shipping the vehicles back north. Unfortunately, due to the increased
dangers that now exist in Colombia, Central America and Mexico, we are
reluctantly and regretfully bypassing these lovely countries for our own
safety. How very sad and we all hope for a change there soon.
Since Panama and Costa Rica are not in this
category, we may have a try in each of those countries too on the way north.
Once we arrive back in the United States, it
is our intention to drive to Texas/New Mexico and intercept one of these
birds as they enter the US from Mexico. With luck, we will follow one north
through the spring on the Great Plains and then continue into Canada until
we reach the edge of the boreal forest and the end of the road.
From there, we’ll return back home in May.
Whenever possible, I will be writing a blog
describing the trip here on the FRG website. We invite anyone with an
interest in peregrines and migration to join us over the journey. In some
locations it will obviously be difficult to reach the Internet but be
patient and we’ll send when we can.Team members this
