Nature Journal Field Trip to Sacramento Valley

On June fourth I will be participating in the Bay Area Nature Journal Club field trip with Jack Laws! I’m always excited to go Nature Journaling with Jack. Last time I went with him we saw four peregrine falcons including a dramatic hunt and kill.

For this month the trip will be to the Sacramento Valley Rice Country for some exciting bird action!

The rice farmers of the Sacramento Valley have worked closely with bird conservation groups to maximize the wildlife potential of the fields. In springtime and early summer rice fields are thriving bird nurseries. The Nature Journal Club will be the guests of the California Rice Commission for a rare behind the scenes tour of Sacramento Valley rice farms. We will search for nesting birds and learn about bird friendly agricultural techniques.

The program is open to all ages and ability levels. No registration necessary. $20 suggested donation.

Seeing and Not Seeing

“The world is full of obvious things which nobody by any chance ever observes.”

–Sherlock Holmes

Have you ever revisited somewhere that you have been many times and seen things that you didn’t notice or never paid attention to before?  I know that I have.

Have you ever noticed that after shopping for one type of a shoes or reading about one type of animal all of a sudden you are noticing them everywhere? I know that I have.

It is easy for the conscious mind to come up with faulty explanations for these occurrences, such as, “Wow. Everybody is getting the same shoes as me now.”  But the truth is usually not in the outside environment but in one’s own perception.

When I was a kid, growing up in Southern California, I was very observant and I noticed more things in nature and saw more animals than the average kid my age and much more than the average adult. However, I was an untrained naturalist for the most part and when it came to birds I knew few by name. When it came to local birds of prey I knew even fewer by name. The name that I definitely did know was red-tailed hawk. And sure enough, the only raptors that I remember seeing were red-tailed hawks.

Later, when I moved to another part of the state for college, I had the good luck of taking a natural history class where I learned about five different local birds of prey and learned to identify them frequently in the field. My first interpretation was: “Wow, there are so many more raptor species here than in Southern California, there must be some environmental reason.”

In subsequent visits to Southern California however, I started seeing many of the other species of raptors. Apparently, some of what had been “red-tailed hawks” turned out to be red-shouldered hawks, and some were probably even accipiters, while surely many of the other birds had just gone un-named and therefore un-noticed.

The field of cognitive science has learned a lot about perception in the last few decades and much research has been focused on vision. Most people take what they see for granted as an unadulterated, objective view of reality. As it turns out, what we see is vastly mediated by what we know, what we think we know, and what we expect or don’t expect.

If you only know the name of one kind of bird you might not see much else besides that bird. But if you read a whole book about the elusive Cooper’s hawk you will probably start seeing them (and hearing them) all over the place.

The morals of the story are:

  • What you see and what you don’t see is shaped by what you know and don’t know.
  • Don’t jump to conclusions about environmental reasons for what you see or don’t see.
  • You can train yourself to see more

 


I will be adding more related articles about observation in small digestible segments.

 

Tracking Birds

Many animals do not leave tracks in easy to read substrates such as sand and mud. Some animals climb trees, swim under water, or fly in the air. Other animals burrow under the ground or slide across it on a mucous-lubricated peristaltic stomach-foot (snails and slugs).

Are these animals impossible to track?

I take a holistic approach to tracking and would argue that everything leaves tracks including fish in water, birds in the air, and slippery slugs. It is often necessary to change your perspective or think outside the box to see or infer these “tracks.”

I recently wanted to see the tracks of a bird that I have never seen walking on the ground. It is a common bird that prefers to perch on branches or fences, flying out to catch insects on the wing. There were a couple popular perch spots near my house and I decided to create “tracking traps” on these spots. I simply sprinkled some fine dust on the flat surfaces (cheap white flour works well (unless the animals are gluten-intolerant)).

Luckily one of the perches was on the edge of a wine barrel so there was plenty of flat space to put the dust. I knew the bird perched on the very rim of the barrel. I tried to get dust on the rim but I also hoped that the bird might venture a footstep or two onto the flat area.

Immediately, the dust began recording interesting information. A variety of marks were being made in the dust, some clearer than others. One added benefit was I could tell which scats were new because they were on top of the dust.

While I have yet to get the footprints that I hoped for I did get some perhaps more interesting and important tracks. Tracks are not only made by feet and in this case the tracks appear to be made by the other set of appendages that birds have, the ones they fly with. Look closely at the photo to see the marks left by an extended wing. You can even see the individual ridges on the feathers if you look closely.

This experience has several embedded lessons:

First, all animals leave tracks. They might be vortices of air or thermal disturbances that we usually can not see. Or they might not be what we think of as tracks and we might not know how to interpret the pattern.

Second, you can manipulate the environment to accelerate your learning. You don’t have to travel 50 miles to sand dunes or riparian areas that have the best substrates for tracking. You can sprinkle flour or rake out a good spot of dirt in your yard.

Third, be prepared to notice and learn what you weren’t expecting. Even though I was hoping to get footprint tracks I got something else. If I had been so fixed on seeing footprints I might have missed the subtle tracks left by the bird’s wing. Often times this unexpected lesson is the thing you really need to learn about more than the thing you were looking for.

 

Guessing Game: If you think you know your bird scat and habits try to guess what species this is. I will reveal the answer in a future post 🙂
