Dangerous to Wildlife

A few days ago I wrote about the dangers of baling twine to ospreys.  This is what it looks like up close.  I found it on the edge of the road on the way to the turnoff for Chimney Rock.  I picked it up to properly dispose of it, but I took some photos first.  It’s made of plastic and seems light as a feather.  Given that it is used and has been coiled up, someone probably picked it up from a field and intended to dispose of it properly, but lost if from the back of a truck.  It looks like there are about three or four separate pieces of twine.

It was interesting that I found it yesterday morning because I planned to go out Limantour Road to check on something and on the way I intended to check on some osprey nests in a canyon that runs up to the road.   The two nests I had in mind were there and there was an osprey in each nest when I arrived.  I spotted a nest farther out that also had an osprey in it.  The osprey in the closest nest took off shortly after I parked my car in the little pull out.

No Baling Twine

This is the closest nest.  It’s about 75 to 100 yards from where I parked.  The other nests are even farther away.   There didn’t seem to be any young in the nests.  I didn’t see any baling twine in them either, which was good.  The nests are not very close to the ranching areas of Point Reyes which lessens the chance that twine would get into them.  Plus,  I assume the Park Service has made an effort to educate the ranchers to the potential dangers of leaving twine in the fields if they didn’t know of the dangers already.

Update:  after I drafted this post I went out to my car and pulled the stuff apart.  There were five equal lengths.  Each was roughly 20 feet long.  It cuts easily using  a scissors.  It was very hard to cut with a box cutter.  I gathered each piece so it was four strands wide and then cut it across five times so I ended up with roughly foot-long strands.  It didn’t take long.  I then put all the pieces into a medium size plastic bag which I tied at the top.  The bag could have held several times more twine.  If the bag winds up on the top of a landfill it shouldn’t pose a potential risk.  I think if I were a rancher and had lots to get rid of I’d maybe skip the cutting and put it in large bags that were sealed closed.  There may be ways to re-cycle it as well.

If you come across any of this stuff please pick it up and dispose of it properly.

Baling Twine, Potential Osprey Death Trap

Osprey Nest Comprised Mostly of Baling Twine

As I was driving home after my visit to Yellowstone and Grand Teton National Parks, I saw something in the distance that caught my eye.  It turned out to be a raptor nest made mostly of baling twine.  I didn’t see any bird(s) in the nest at the time, but given the nest itself atop a power pole with baling twine as the main nest material, and the fact that the nest was near a river, I assumed the nest was built by ospreys.

I wrote an article about the dangers of baling twine to wildlife last August.  It was triggered by a photo I took of a bull elk with a bit of baling twine caught in its antlers.  You can read the article by clicking here.  Ospreys are especially prone to injury and death by baling twine.  The internet is full of articles about ospreys and the deadly effects of baling twine on them.  Ospreys really like this light, soft material for nest-building.

The nest is close to the highway and at the entrance to Cooke’s Warm Creek Ranch which is in the Victor, Idaho, area.  I did a google search and got one hit for the ranch.  It turns out that the ranch is the site of a wetland restoration project that was done by Ducks Unlimited, the Teton Regional Land Trust and the ranch.  That told me that the rancher was interested in protecting wildlife.  You can read about the project here.

Location of Nest

I felt the nest was an issue I needed to pursue.  I called the Teton Regional Land Trust and spoke to a fellow named Matt.  Matt was aware of the nest.  He told me the nest has been used for 15 years and, so far, no casualties.   He said baling twine is a serious problem and his organization has been working with ranchers to make sure no twine is left in the fields any more, but that there are nests like the one above with twine in them due to old practices.  It’s not a simple matter of going to the nests and removing the twine because ospreys may abandon the nests.  Because of this concern Idaho fish and Game’s policy is to leave the nests alone unless there is a power problem cause by the twine.

The upshot of this is that I have a better understanding of the problem.  Just because a nest has baling twine in it doesn’t mean it should be removed from the nest.  It seems to me the most important thing to do about baling twine is to not let ospreys get any of it in the first place.  That means educating ranchers about its dangers.  The Regional Teton Land Trust is doing that as I’m sure many other organizations are.  I hope the manufacturers of baling twine are doing that as well with some sort of warning on their packaging.

Matt told me that Warm Creek is just that.  It is a spring creek that, due to its warm water, is an important open water area in winter for species like trumpeter swans and moose.  It is a tributary of the Teton River.
