Photo by Miranda Kennedy
Today Miranda and I (mostly Miranda!) spoke about native San Diego plants that were best for birds. Miranda’s excellent bird photography and her in depth knowledge of wildlife behavior made our talk for the Audubon San Diego Bird Conference very informative. She is always fun to speak with, too. We presented a slide at the end that listed plants that were featured in the presentation and I promised to post it here. By no means is this an exhaustive list; birds will take advantage of any resources they can to survive. However these plants can be purchased and planted in landscapes (we notably left off the poison oak in the above photo, which is a excellent food and habitat plant, especially for towhees who prefer to nest in it!). And here it is:
Through the fall so far, the wildlife cameras have continued to offer an enchanting insight into the usually unscrutinized, quiet shiftings of our habitat.
We’re obviously looking for animal activity on the cameras, but sometimes late or wind-blown-plant triggers capture some beautiful moments from the little ecosystems the cameras overlook.
Daily, nightly, a lot of the same animals appear over and over, filling up the SD cards with hundreds of iterations of the same pieces, in snapshots or 15-second installments, of the same stories. This can be challenging to process, but we love the way we’ve come to know the patterns of some of our wildlife’s lives, and even know individuals.
We love this opportunity to learn about and appreciate each little story: the summer evenings where spidery crane flies fill the creek’s small barranca well with their dramatic bumbling — skittering, over-exposed, in the capture of the infrared lights;
the black phoebe caught, again and again, in Muybridge frozen energy, in aerial sallies on winged insects attracted to the big pond in the afternoon warmth;
the long, still moments as an animal just stands, and looks, pulls in the air and lets its carried scents and noises sink in.
And, of course, we do still covet the unusual — even, playfully, the impossible: as any kid knows, dreaming (im)possibilities is half the fun of any endeavor (“Iron-flanked and bellowing he-hippos clanked and battered through the scudding snow towards us as we passed Mr. Daniel’s house.”). What could come here? I want rare birds to thoughtfully pose, in focus, on the cameras — and also to see a weasel. Maybe lots of weasels. And a scissor-tailed flycatcher would be great. Mom wants hedgehogs and foxes. Reasonable, right?
Well, turns out the foxes are pretty reasonable!
Who knows whether foxes have come through the property before. Who knows if one ever will again — or if it will pass through in a place and fashion that allows our cameras to record it. Tantalizing and wonderful!
(And my weasel dream looks brighter than ever!)
Quotation from A Child’s Christmas in Wales by Dylan Thomas
Delightfully, the streambed wildlife camera has also been picking up an adorable owl visitor these last couple of months. Western Screech Owls (Megascops kennicottii) are certainly present in the area, but much less common to see than Barns and Great Horneds — they’re more reclusive than those much larger species, hunting mostly different prey and small enough to be at risk from larger raptors themselves. The ones on our property have made themselves known by the distinctive “po-po”, ping-pong-ball-bouncing call that only ever rises up from the tangle of trees in the streambed. We’ve only seen one in person on the property once, when a tour stop under the Big Oak above the stream woke it from its chance nap inside the disheveled old owl box dangling from a branch.
But we seem to have at least one — apparently very dirty — screech owl hanging around this summer, taking baths at the camera point at least a couple times a week. And it’s just the cutest darn thing.
Here in lower elevation areas of Southern California, screeches stick near waterways because those habitats are where we have large trees; as cavity nesters that have adapted to have cryptic coloration and patterning that allows them to blend in with bark, large trees are essential. Happily, we have some big trees extant and growing in our little slot of land. And we have a number of conservation organizations locally who are working to preserve wild land and especially land connected to waterways, as these are always areas of higher species density and diversity. And they say that Western Screech Owls readily use owl boxes made to their dimensions. Wish list!
This year Finch Frolic has been particularly beautiful. Of course, this year we had to close down throughout the spring. Fortunately we’ve been able to reopen for limited-capacity tours with safeties in place. However, I really miss sharing how lovely the garden is, and I want to let you have a little tour right in your home.
These photos were taken this morning before the temperature rose; its in the 90’sF here today, in North San Diego County. I apologize for the phone camera, as my good camera is in for repair. I only wish that you could also smell the moist mulch from the light overnight dew, or hear the clug-clug of the crow, the tittering of a flock of bushtits and the scuttling of lizards through leaves, which I experienced as I walked around the garden. All of these friends and so many hundreds more are working the garden today and every day, keeping it in balance.
Our food forest is a low-water-use garden, on poor soil, using no additives to the ground other than occasional compost. There are no herbicides, pesticides or other factory-made chemicals used here, and there are two of us who care for the garden. Most of the seasonal beauty this year is due to the diligence of my daughter Miranda who took seed sprouting to a whole new level even before the pandemic arrived. We rely heavily on the insects, birds, lizards, frogs, soil and water microbes and creatures to do all the work protecting the plants, and the plants themselves to create good soil. All we add is a low dose of salty well water which the humus cleans, and leaves or sheet mulch on top. Our fruit trees receive a dose of blender compost once in awhile. Miranda and I hope that these photos bring you peace and lift your spirits, and that knowing you are looking at a safe habitat that is thriving with life gives you a feeling of security as well. It can be done. Permaculture must be done. Best of health! Diane
A WALK ON THE TINY SIDE
Remember this image of a sneaky syrphid fly larvae? Well, what I didn’t point out before was that there’s an even sneakier attendee at this aphid-nomming party. And she’s that little black line across the white leaf vein in the top middle of the photo: a parasitoid wasp.
Parasitoid wasps are pretty full-on — their simple life functions can include grotesqueries you thought only originated in the imaginations of sci-fi script writers. But they’re part of the complex web of ecological checks and balances in their systems.
The difference between parasitic and parasitoid is that a parasitic animal generally doesn’t kill or even directly seriously harm the host; it needs the host to continue functioning so that it can support the parasite. A parasitoid uses the host up in the process of supporting its own growth and/or reproduction.
That sneaky parasitoid lady and her cohort are the authors of the scene of destruction above. What look like little brown bumps on my Brussels sprouts leaf are in fact the corpses of aphids: the dried, hardened exoskeletons of used-up hosts. You can even see a small, round hole in the top of one — the door the exiting parasitoid punched out and left open behind it.
Parasitoid wasps like this one home in on the distinct chemicals released by the feeding and typical drama (like terror over a syrphid fly larva attack) of an aphid colony. Fertilized females settle on leaves and begin their prowl.
They’re looking for nice, juicy aphids that will be able to feed their grubs to adulthood. With a quick stab of her ovipositor, a female wasp injects a single egg into a chosen aphid, then prowls on. Once that tiny egg hatches, however, the aphid will slowly be hollowed out from the inside by the hungry, growing grub, until only a husk is left and the mature wasp breaks its way out, exercising its brand-new wings in flight for the first time.
The world is made up of opportunities being taken: everything is a resource and every resource is a chance for an existence to bloom. Sometimes, that existence is just really horrific. But it works for them and it works to create a functioning ecosystem — dynamic equilibrium — so we can all actually be very grateful for the parasitoid wasps.
Creeped out, but grateful.
A WALK ON THE TINY SIDE
Another blooming colony of cabbage aphids (Brevicoryne brassicae) on my brave Brussels sprouts: a familiar sight, especially as the weather warms.
But wait — what’s that?
That! The green thing!
It may look a lot like a cabbage white butterfly (Pieris rapae) caterpillar, but it’s definitely not. Take a closer look and you’ll see that rather than a mouthful of sprout leaf, this little green guy is munching on aphid.
One of the most numerous, in terms of species, groups of animals on Earth are the flies, order Diptera. Like any large family, there are some gems, some bad apples, some neutrals — and of course, all that depends on your point of view. To aphids, larvae of some Syrphid flies (family Syrphidae) are stone cold bad-‘uns.
Also known as ‘flower flies’ and ‘hover flies’, these natty little fellows pull a lot of weight (each species in its own way) in both natural and altered ecosystems. Their secret is in their adaptable nature: they’re able to take to human-made environments, so are often some of the only native wildlife in housing developments.
Most species in North America as adults mimic bees with yellow, black and striped uniforms and certainly rival and even surpass native bees in pollination services (bees are generally more sensitive in many ways and so are more often excluded or eliminated from habitats). They eat nectar and pollen, as bees do, thus the common name ‘flower fly’.
And of course, most syrphid fly larvae are voracious predators of aphids, making them powerful elements of any garden’s pest management system (a.k.a. ecosystem). Be sure to make friends with yours! Get in touch with Pest Control Cincinnati
We took a rare day completely off work last Thursday and had a rainy day in. I say “off work” — we did get some tasks done, but they’re fun tasks that get pushed back by more serious jobs. Seed shopping (!!!) and checking our wildlife camera SD cards.
The wildlife camera on the wild streambed at the bottom of the property is set to take 15 second videos. Going through these can be a bit of a chore — maybe several hundred to over a thousand a month, and so many are just waving leaves or half a second of raccoon tail going out of shot at the start and fourteen and a half seconds of mud and leaves. Or rats. Lots of thirsty rats.
The site the camera’s positioned at is an intersection with a runoff vein from another property, so it’s a real bird hotspot, and the streambed acts as a road for larger mammals. Wading through the dreck can really pay off — that’s why we have the camera down there still.
Imagine our startled shrieks of delight when we clicked off another “wind” video and encountered this big, stubby payoff:
It’s not every day you get to add another mammal to your property species list! Come eat our rats, Mr/Ms Bobcat!
In the still of the night….
[Five minutes later…]
That nocturnal birds eat at night is a pretty straightforward piece of knowledge — awake at night, ergo eating at night.
It’s also pretty clear to anyone who finds a large dropping on their car in the morning that wasn’t there the evening before that other functions of life have to happen in the hours in which we sleep or stumble into things as well.
It’s funny how surprising it was to me to be confronted with the fact that owls — as of course they must do — also bathe at night.
Need to install an owl-dryer out there!
Finch Frolic is home to many Desert Cottontails.
More all the time, in fact.
Or at least very solid population replacement.
We see them all the time because they are pretty comfy here and used to us, just scooting around nibbling grasses and fighting the ducks (I gotta see if I have photos of that to share — hilarious bunny sass…).
The funny thing is how infrequently they appear on the wildlife cameras, and when they do, they’re invariably being rather sneaky.
Sometimes, it can start to feel a little spooky….
— Run awaaaay!
