Our curlew
trapping season has begun! We have 19 transmitters that we will be putting out
this spring on Long-billed Curlews at various locations. Here’s an update on
the season so far.
The
Transmittered Birds
We have
transmitters on 3 ACEC (area of critical environmental concern) birds so far, and plan to do a fourth in the next few
days. Because we are working with schools and community groups in the valley to
get the word out about curlews (and especially about not shooting them!) we
thought we would ask some local schools to help us name the ACEC birds.
Our first two
birds have already been named, based on votes and suggestions from 300 biology
and ecology students at Middleton High School. Thanks for Mr. Love and Mr.
Wiley for letting us visit your classes!
So, without
further ado, allow us to introduce our first two named birds of the 2015
season!
Meet: Thor and
Valkyrie!

These two birds
are a mated pair living on an area of the ACEC we have called “mountain view”
because of the beautiful mountains visible on the horizon at this site.

Appropriately,
this couple is named after characters in Norse Mythology, since the mascot for
Middleton schools is the Viking.
Two of our birds
will be named with a naming contest based on a combination of submissions from
area schools. We have a
female, CP who has yet to be named, and hope to catch our fourth bird soon.
The season so
far and what’s ahead…
We have 7 study
sites throughout the Intermountain West where we will be trapping birds this
year, but for now we are focusing our transmitting efforts in the Treasure
Valley. With its lower elevation and warmer climate, the ACEC (our study site near Emmett and Middleton, ID)
is the first location to have nesting birds. So, we are working to catch
curlews there before moving on to our other study sites. Stay tuned for updates
from the field as we begin attaching transmitters elsewhere.
Over the past 5
days, we have managed to catch 6 curlews total. Although we usually make it
sound easy, this season has been particularly taxing on the trapping team. So
far the score is 4-6 curlews vs trappers. This is our highest ‘miss’ rate so
far! For some reason this year, we have had more birds than usual flush before
we can get near them with the net…maybe their friends who are already sporting
some of our ‘jewelry’ have warned them about us!

One particular instance,
we were gearing up to trap a female incubating on her nest. Just as we were
lining up the net to make a go for her, Jay flushed a female curlew from the
ground from just a few feet away! Apparently this female had been sitting on
her nest, quietly incubating her eggs while we were setting up the net just
yards away from her. She squawked once as she left the nest and the jig was up!
The female on the nest we planned to trap saw the entire interaction and wasn’t
about to let us get anywhere near her. We had to give up on that area and move
on.
We place a covering over the curlews’ heads to keep them calm…. it makes them look a bit like a sock puppet, but it gets the job done. |
Spit Swabs
This year we
have BSU grad student, Stephanie Coates, working on the project with our
research director, Jay Carlisle, as her advisor. As part of her study, she’ll
be investigating the genetics of our 7 curlew populations. We’re hoping this
will help us piece together a better picture of curlew population connectivity.
Because of this, we are catching some curlews to attach transmitters and take
DNA samples, and others we are simply banding and taking DNA without attaching
a transmitter.
So far we have
trapped 3 curlews for DNA samples and 3 curlews for DNA+Transmitters.
Obviously the curlews don’t enjoy this process, but it is a relatively efficient and very safe technique for collecting DNA from them). We are excited
to see what discoveries the DNA will reveal!
While taking a
spit swab, we also got to experience a strange phenomenon that none of us were
expecting! We’ve always noticed the grooves on the tips of curlews beaks and
wondered what they were for, but had no idea they were actually flex lines!
That’s right, curlews can actually bend the tips of their beaks!
While chatting
at a barbecue with our bird-nerd friend Bryce (because what else would you talk about at a
barbecue?) we learned that this is actually a known phenomenon in other bird species as well, known as Rhynchokinensis.
Well, that’s all
for now!

already, be sure to follow us on Social Media. You can follow our main IBO
pages, and we also have some curlew-specific pages with more frequent updates
for those of you who are curlew super-fans :)
