Gary:
In case anyone asks, those artificial raptor perches we (the county) put up in  the open space areas on Mount Diablo DO work.

I got up to North Lime Ridge early for a work party so I could look around and saw a red-tailed hawk on one of the perches. I stopped and watched.

Bird watching with Crazy Bird Lady of Concord’s Ellis Lake

Gary:
Today at Ellis Lake I was privileged to see a green heron, a hawk that I think is a red-shouldered hawk and a common merganser (male) duck.  Just one.  I know there’s probably not an answer to this question, but HOW can one duck get lost from the flock and end up in a tiny lake in the middle of Concord?  He looked like he couldn’t decide whether to hang out with the mallards and try to blend in, or float around with the young seagull.  I don’t think I’ve ever seen a merganser before, either.

Turkey vultures and hawks enjoy the skies together

Gary:
I had to write to you to ask a question: Just thought it was curious and a little bizarre to see our red-tailed hawks soaring in formation with our local turkey vultures, with all of them getting along just fine!

In this picture I’m including above, it’s a red-tail soaring along with a vulture. I have several pictures of them soaring along together, and they were not fighting at all. If anything, they seemed to be enjoying the day, and each others company. It was quite weird.

I have several others with 5 or 6 vultures and a red-tail and a peregrine all flying in formation … and trust me, it’s the oddest thing ever … they obviously enjoy each other’s company …  I think it’s just a little bit odd. (Alfred Hitchcock would be proud!) Is this common behavior?
Greg Merritt,Vallejo, California

Greg:
Yes, hawks and vultures will often cruise around the skies together. They don’t compete with each other, or prey on each other. We probably see them flying around together a lot more often than we realize, since they can look so much alike when they are up there circling above us. /Gary

Little kingbird tells BIG swainson’s hawk where to go (“get lost!”)

Small birds can get pretty aggressive when a bird of prey like this swainson’s hawk flies too close to their nesting area. Take this Western kingbird, for example. It is only 9 inches tall, compared to the 19+ inch tall swainson’s. And probably outweighed 15-1. But that doesn’t stop the little kingbird from telling the monster swainson’s where to go.

The power is in the heart. Bye-bye, swainson’s hawk. /Gary

Scrub jay tells red-tailed hawk to “Get lost!”

Gary:
We have a red-tailed hawk nest in our neighborhood.  Every year they come back to lay eggs.  The babies are about 6 weeks old now, very cute! When I went out to take a picture of the mom at the top of the tree, I noticed a scrub jay flying around it, basically squawking and pestering it.  Why would a scrub jay take on a hawk?!?
Lissa Heaton Severe, Walnut Creek, California

Lissa:
It is the nature of small birds — jays and mockingbirds in particular — to kick up a BIG noisy fuss whenever they encounter a bird of prey. They are Nature’s alarm system that lets all the other birds know when a predator is in the area. They will also do the same when they see a cat, and sometimes a fox squirrel. Fox squirrels are known to rob bird nests, eating eggs and sometimes small chicks.

Jays and mockers are smaller and faster than hawks, so unless they get too close, or careless, they can pretty much jump up and down and scream their heads off and do what they want without getting caught. The hawks know this and will often just ignore them. /Gary

Hawk peeks over top of nest while incubating eggs

I get many requests from readers wanting to know what hawk nests look like.

Check out the Swainson’s hawk nest above. Note mama hawk just peeking over the top of the nest while she’s incubating her eggs. Red-tailed hawks, similar in size to the Swainson’s, construct their nests out of an identical-size mix of sticks, leaves, grass, etc. /Gary

Pushy little blackbird chases BIG hawk away from nest area

“Hey! Get out of my airspace,” said the blackbird to the Swainson’s hawk.

Blackbirds are tough little characters, especially when they are protecting their nest areas. That protection appears to include the airspace directly over where the nest is located … as this Swainson’s hawk is finding out the hard way.

The hawk may be bigger than the blackbird, but it’s not as maneuverable. As far as the blackbird is concerned, there’s also a bit of safety in numbers. When one blackbird goes on the attack, the others come running … er … flying. The blackbirds, being MUCH smaller and lighter, can’t really do any damage to the hawk, but in nature, animals rarely come to actual physical blows. It’s all about posturing and image. Just ask any blackbird. /Gary

Wild birds help us connect with nature

Native Bird Connections is a nonprofit organization that uses a collection of live, tame, nonreleasable eagles, hawks and owls to educate people of all ages about the wonders of nature. Last year they presented 584 programs that touched the lives of 17,792 people — including school children, scouts, senior living programs, after school enrichment programs, state and national park programs.

As Native Bird Connections supports our young people in their search for knowledge of the natural world around us, this organization also needs our financial support to help them survive these tough times.

Cooper’s hawk grabs a bird in a local backyard

Gary:
I was sitting in my family room at home (near the foothills in Pleasanton) working on taxes this afternoon, when a saw a flurry of activity and what turned out to be a cloud of feathers out the window. I went out in the backyard to see what the commotion was, and I saw what I believe was a Cooper’s Hawk on top of the fence with his prey. I went back in and got my camera and proceeded to watch him de-feather and eviscerate what I fear may have been a baby bird. He didn’t seemed concerned that I was standing there and I was, for once, finally able to get the great backyard wildlife photo I was trying for. Eventually he flew off with what remained of his prey. It was a cool moment, although I still felt bad for the victim!
Michelle Foy, Pleasanton, California

Michelle:
We can always feel bad for the “victim,” but that’s how life works in the great outdoors. Everything has to eat something else in order to survive. The hawk eats the bird that eats the bugs that eat the grass … ad infinitum. And the turkey vultures and the dermestid beetles are always standing around in the wings, waiting to pick up the pieces. Life goes on. /Gary
