more nest building and first egg!

Yesterday the little hummingbird continued working hard building her nest.  She’s using small twigs, leaves, grass seeds and spider silk among other things.  Both of the following videos are best viewed in HD and full screen.  Here’s yesterdays action:

And here is today’s action.  More nest building and her first egg:

I have been keeping a small jar with fur from my dog Ham (now in doggy heaven). This morning I decided to attach some of her fur to a piece of wire and hang it in the flight path of the nesting hummingbird. Sure enough, she found it and started using it in her nest:

Hummingbird Nest Progress

About a week ago I noticed a hummingbird landing on and placing random bits of plants on a hanging vine in my patio.  It was so random I didn’t bother setting up the camera.  I figured it was too late in the season for nesting.  However, during the last few days I realized the female hummingbird was actually making a nest.  So I finally set up the video camera to record her progress.  I think she is a broad-tailed hummingbird.  What do you think?  More to come:

Monsoons

After what seemed an eternity of dry hot weather, the monsoons have finally arrived.

This is the time the desert plants and animals become more active and the Sonoran Desert morphs into a living terrarium with the simple addition of rain. Because of this it is my favorite time of year, despite the high temps and humidity.

This afternoon I set two new camera traps in a mountain range SE of Tucson. On the way to the sites I had selected I came across some common, but beautiful insects:

More Wildlife

Despite the recent absence from my blog I have continued to capture photos and videos of things that interest me.  Most recently, I’ve been focused on Sonoran Desert nature.  Here are some favorite videos from the last few weeks.

Summer

It’s been a long few months since finishing my tour on Sea Sheperd’s Operation Milagro. I worked on-board as a deckhand hauling in illegal nets, briefly as quartermaster on the bridge and primarily as one of a few drone operators.  Here’s is Operation Milagro’s season end recap video:

During this time my dad passed away and I spent a few week back in Tucson with family.  I officially left the Sea Shepherd campaign after my three month commitment ended at the end of April.  At that point I needed a break to re-energize and reflect on the loss of my dad.

Since that time, I’ve been back in Tucson working on my house and volunteering again at the Arizona-Sonora Desert Museum.  I’ve also been catching up with my wildlife camera-trap projects at home, the Catalina Mountains and at the Audubon’s Appleton-Whittell Research Ranch.  I’ll be posting regularly now that things have settled down.

Sea Shepherd and the Vaquita

During the first week of January I joined the Sea Shepherd Conservation Society’s (SSCS) Operation Milagro in the Sea of Cortez. Operation Milagro targets poachers who illegally set gill nets to catch totoaba, an endangered sea bass. In doing so a highly endangered porpoise, the vaquita, is often caught and drowned in the gill nets. The most recent population estimates for the vaquita place the number well below 100 individuals. The number of totoaba remaining is unknown. Our mission is to find the gill nets, pull them from the sea, destroy them and then hand them over to Mexican authorities.

Why do the local fishermen target the totoaba? Its swim bladder has purported medicinal and virility enhancement value and is sold for great profit in China.

While I can’t post the best video I’ve taken since Sea Shepherd will be using it in future videos of their own, here is a short video of interesting outtakes:

I am working on the SSCS ship named the Farley Mowat, named after the author who wrote Never Cry Wolf among other works. My primary role on the Farley is “drone pilot” and I am responsible for catching all the action from an aerial perspective not otherwise possible from the ship or a small rigid inflatable boat (RIB). My second role is that of deck crew. In this position I assist the other crew in taking aboard the illegal nets once we find them. This is difficult, back-breaking work as the nets are hundreds of meters long and are set in the shallow, current-filled northern Sea of Cortez waters by anchors that weigh nearly 150 lbs.

During my first few weeks aboard the ship we have found and destroyed over twenty illegal nets and the totoaba season is just beginning. We find the submerged nets by towing a “ray” behind the ship. The ray trails a grappling hook and is designed to skim along below the waters surface and snag the net. Once a net is snagged, a line purposely snaps and the ray and a set of marker buoys is let go into the sea. In this way we can turn the ship around and relocate the buoys, and thus the net.

Camera Trap Action

I recently set up a white-flash camera trap on the waterhole in my backyard.  The difference between this camera and other traditional camera traps is that it uses a white-flash, just like your camera flash, to capture the photo or video of the animals when the motion sensor is triggered.  Many camera traps, including several of mine, use IR, or infrared light to capture the action of the animals.  Infrared light is not visible to you and me or wildlife.  Because of this the camera can be triggered and the action captured without the animal being startled by seeing white light.  The risk of using a white-light flash with a camera trap is that the animal will see it and run away.

Here is an example of a non-visible IR camera trap capture:

In this case, the animals were revealed by the infrared light, but they did not see any light and everything remained dark for them.

In the following video my camera used a white-light flash to capture the action.  This is the same as using a flash on a DSLR in low light to catch everyone’s smiles.  Since the animals can see this, it often startles them thus changing their behavior.

In my back yard it seems the animals are adjusting to the white light when they approach the waterhole:
