the ravens and the bobcat
After a day of what could be the last rain of the season, I decided to motivate myself for a much needed attitude adjustment. I was grumpy, and pretty unmotivated. I knew if I went out for a wander/hike, things might shift. I figured “future Zach” might really appreciate “past Zach” more if “current Zach” got off the couch.
It was just before sunset, and the clouds were starting to break up, yielding some blue sky and a beautiful setting sun sometimes shining from behind the clouds. The puffy clouds that were left after the rain were now highlighted in beautiful pinks, purples, and oranges. The air was calm and there was a divine serene quality to the light and the moment.
I wasn’t far into my wander when I heard a lot of raven sounds. It’s not unusal to see them in this area, but usually they are moving around, soaring, and don’t typically hang around one particular area for too long. And usually they are in pairs here. As I turned a bend, I started to see them. Some were flying, some were perched or hopping around a grove of eucalyptus trees. There were at least four or five ravens, and I stopped to watch and listen. At first I thought perhaps it was a young family of newly fledged ravens, just playing on the hillside and in the grove of trees. They didn’t necesarily seem focused on anything in particular, but I decided to circle around to the other side of the eucs to get a better look.

I’ve written before that in the northern part of Wildcat Canyon Regional Park, I have never seen definitive bobcat sign nor a live bobcat in the three years that I have been going there (ironic, given its name!!). My explanation was that due to the open grassland and minimal cover in this area (most of it is grazed by cattle for fire suppression), coyotes are the dominate predator because they can adapt to the terrain better. Between the lack of cover and proliferation of coyotes, it is not ideal bobcat terrain. Not only that, many people walk their dogs in this area, and again, coyotes are better equipped to deal with that scenario. Bobcats like to be near edges of vegetation, so they can easily “disappear” to escape threats. Further south in Wildcat Canyon, there are more chapparal and riparian zones with lots of cover, and sure enough I’ve found (and seen) bobcats and their sign there.
That all changed a few months ago. I was out after dark in the northern part of Wildcat and somehow in the dim light I spotted a single cat track in a patch of mud on a lightly used cow trail in an area under eucalytus trees and close to more dense cover (other trees, poison oak, blackberry, coyote brush, etc).

Then, in the middle of April, I was on a run passing through the same general area and I spotted fairly fresh bobcat scat. It was classic bobcat scat – sometimes coyote scat can be a similar size and they can be confused, but not this one. It definitely tasted like bobcat scat (joke).

The evidence was mounting that a bobcat had moved into the area.
Back to tonight …
As I came around the other side of the euc trees I saw two ravens side-by-side on a branch, not very high up (probably 20 feet). They were very vocal and seemed to be focused on something on the ground. I paused, then slowly approached through the tall grass. As I got about 1/4 of the distance to them, what pops out from behind some tall grass? A bobcat!!
I froze. It froze. It thought I hadn’t seen it, so it slowly backed behind the grass, crouched then slowly turned around and started to go the other way. I quickly backtracked to the trail and returned in the direction I had come in hopes that I would see it try to circle back around me. As I did this, I kept track of what the ravens were doing – they had watched the whole encounter happen and now I realized they had absolutely been following this cat. As I paused in the trail after about 20 yards to listen and gauge my next move, the ravens flew over the area directly in front of me and circled a few times. They were tracking the bobcat and giving away its location! Sure enough, in about 10 seconds it appeared at the edge of the trail only 15 feet from me. We gazed at each other, and it slowly crossed the trail, pausing at the other side to study me. Slowly it moved in a circle around me and then passed, stopping to watch me at a number of times. OF COURSE I didn’t have my good camera rig with me, but, I was able to really enjoy a few moments of being close to this amazing animal – and snap a bad pic with my cell phone.

I love when “bird language” gives clues like this about what is happening on a landscape. That is part of the fun of being out there and staying aware – and no matter how many times it happens to me, it always seems like magic. So fun.
Right after that encounter, I saw a California newt on the trail – likely returning from a vernal pond where it bred, to seek refuge in the leaf litter under some trees during the warm and dry months of summer. I’m always thrilled to see these little salamanders.

Another 50 yards up the trail, as I went off-trail and into some thick cover, I heard and then saw an agitated Cooper’s hawk fly into the eucs where I was headed. Then I heard two great-horned owls respond, irritated about the irritated Cooper’s hawk! The Coop flew off, so I proceeded on. A loud rustling sound quickly caught my attention and I watched as a turkey flew up into some high boughs of a eucalyptus tree to roost for the night. As I walked under to get a better look, I heard the Coop again. I backtracked down the trail to where I had been before, and there in a dead tree was one of the great-horned owls, sitting very calmly with a backdrop of Richmond, Mt Tam, and a twilight sky. And right by it on the other side of the tree was the Cooper’s hawk, protesting loudly. Occasionally it would fly off and then return. This scene continued for about five minutes, and finally both birds departed. I am convinced there is a Cooper’s hawk nest adjacent to the area where the great-horned owl nest is. As I started to walk away, I heard a few juvenile red-tailed hawk calls in the background – hopefully I’ll see them fledged and playing in the area soon.
“Current Zach” is very pleased that “past Zach” got off the couch. Thank you, thank you, to this Land – this Land that has given me so much. The fact that we have such amazing parks so close to an urban area is a testament to the conservation efforts and hard work of so many people here – and I am grateful. Also very exciting that a bobcat has moved into the area, I hope to get to see it more!
the showdown
As I was winding down my day while traveling in southern CA recently, I had the pleasure of watching a showdown between a juvenile red-tailed hawk and an adult Cooper’s hawk (likely a female). When I got back to the house where I was staying, I noticed the juvenile red-tailed hawk perched in a relaxed manner on the peak of the house next door, watching the sun go down.

This hawk is most likely about 1 year old, quite an accomplishment to have survived its first year (raptors have mortality rates in the first year as high as 70%!). Juvenile red-tailed hawks lack a red tail, often have lighter colored eyes than adults, and have some spotty patterns on the belly band (versus more streaking in adults). It seemed relaxed as it faced the setting sun, evidenced by its fluffed-out feathers and its left leg lifted up into its belly feathers. You can see on the right leg, there appears to be a band on this bird – possibly it was caught and banded during the migration last year.
I relocated to a second-story balcony which afforded better views of the bird, and as I stood there watching suddenly another raptor appeared on the scene! On a power line at about eye-level to me, an adult female Cooper’s hawk alighted and assumed a similar relaxed pose to the red-tail, with one foot up as it surveyed the area.

Cooper’s hawks are part of the Accipter genus of birds in the Accipitridae family, and can be extremely difficult to discern from their close relative the sharp-shinned hawk – a smaller version of this bird. Most raptor species exhibit reverse sexual dimorphism, meaning the females are larger than the males. What makes the identification of a Coopers versus a sharp-shinned hawk especially difficult in addition to very similar plummage is that a male Coopers can be about the same size as a female sharp-shinned hawk. In the above picture, there are some really helpful features that help key this bird as a Cooper’s hawk.
-
rounded termination of the tail feathers (versus more straight across in sharp-shinned)
-
dark “cap” on the head feathers (versus more of a full hood on a sharp-shinned hawk)
-
eyes are placed more towards the front of the skull (sharp-shinned hawks’ eyes seem almost in the center of their skull when viewed from the side)
-
thicker tarsus, or leg bone (sharp-shinned get their name from having an incredibly thin tarsus)
I am not 100% certain that this bird is a female, but that is my initial guess based on size relative to the red-tail (which I thought could be a female based on her large size – but again, no great scale for reference).
The Cooper’s hawk didn’t remain relaxed for long – as soon as it spotted the red-tailed hawk perched above it became much more alert, dropping its leg down and staring intently (though, to be honest, all these birds seem to only have a single facial expression – and if there is one word for it, it is “intense”).

In the above picture, you can see the white feathers that protrude below the tail on its ventral side. This is a helpful feature to identify accipiters in the field from a distance, but one needs to be aware that Northern harriers have a similar white patch that appear on their dorsal side.

Finally the Cooper’s hawk decided to move in on the red-tail – likely it has a nest in the area and did not like the red-tail hanging around too close. The Coop flew up on top of the chimney, and the showdown began. You can see the size difference fairly well in this photo (with the Coop on the right).

At this point, the red-tail took notice of the Coop but still had a leg up (no pun intended) and was facing away from it. In what had to be some sort of bird statement, the red-tail proceeded to slice (poo) in the direction of the Coop!

Casually, the red-tail then turned to face the Cooper’s hawk, then took off right in its direction flying just to the north of it. The Coop jumped off right after the red-tail and pursued! At first the red-tail tried to do some circles and gain altitude, but it eventually became a full on chase. There wasn’t much actual contact, but the Cooper’s hawk made its point and the red-tail seemed fine with relocating to a tree not too far away.

Awesome to see these birds and witness this close encounter!
