The ecology of yellow evening primrose in our backyard

There have been several great blog posts about pollinator plants and pollinator gardening, calling attention to both the good and the bad. (the latter post very articulately describes the problems with pollinator gardens). A while back I wrote about my disdain for the trend that was pollinator gardening. OK, disdain is way too strong, but you get the idea.

In honor of national pollinator week (June 21- 27), Kelly Senser from the National Wildlife Federation compiled favorite pollinator plants from gardeners from across the country (click here for the story). In this, I wrote about one of my favorite plants in our garden, the yellow evening primrose, (Oenethera flava). Tonight my wife and I watched as one of our yellow evening primroses opened- click here for a video of it happening (the action really picks up at 55 seconds).

Though the flower is gorgeous, large and showy, the real reason I like it so much is it offers a wonderful microcosm of wildlife gardening. In short, the primrose is moth pollinated, because it flowers at night. That is pretty cool in an of itself, and probably not that typical in the run of the mill pollinator garden. However, the neat thing is this is the host plant for a moth that does not feed on its nectar, since it is a daytime flyer: the five- line Sphinx moth, also known as a hummingbird moth. And where this whole story gets more interesting, and typifies the intricate plant/ insect relation ship is that even though the eggs and larvae are tied to the primrose, it needs something else to complete its life cycle- soft duff or sawdust.

In our yard it finds fresh, loose sawdust at the base of our aspen (Populus tremuloides)trees. The reason for this accumulation of saw dust is that the trees are invaded by the larvae of a long horned beetle- the aspen borer (Saperda calcarata). As the larvae tunnel through the aspen they force out sawdust that collects around the base. Also, as a defence, the aspen pushes sap out these wounds. The sap is a critical food source in the early spring for many species of butterflies that overwinter as adults like the mourning cloak or Lourquin's admiral (shown below feeding ion the sap of an aspen).

So, from this one example you can see how interesting and intimate the association of plants and pollinators are. Furthermore, you can also tell how unrelated some of these plants and animals are. Provide native species, and diverse assemblages and you will be rewarded with much more productive "pollinator" gardens than if you tried to plant a garden for pollinators.

Nesting, nestling and fledging update

There is a lot going on with nesting birds in our garden. We have northern flickers, black-capped chickadee, and red-breastered nuthatches in various stages of nesting and fledging in nest boxes in our small backyard. Here is a breif run down on the actvity....

Black- capped chickadees

The chickadees should fledge any time now- they are ready to go but have probably been delayed by this rain. By the way, thank goodness for the rain!

If you haven't done so already check out the inside of the nest box with our streaming nest camera. But you'd better hurry because they are about to fledge. Click here to go inside the nest box.

At the beginning of this posts is a short video my wife took of the outside of the box and one of the adults feeding the young. For those that only know the chickadees from the inside of the nest box, this view might be interesting.

One thing I am really excited about is that we will be able to capture the mysterious second clutch this year on camera. every year, the chickadees have a second clutch, even after a typically very fruitful first clutch. The second clutch is usually smaller, and takes less time to fledge. It has aways appeared that the young from the first clutch help in raising (or at least with the feeding), the second clutch. Hopefully, though we'll be able to learn a little more of what is going on. It is not really common that chickadees have two clutches, so I am excited to learn more.

Red-breasted nuthatches

These little fellas have been a bit overlooked this year, I am sad to say. Not that they care, but theirs is the only box in which we did not install a nest cam. As a result, we have been so focused on the chickadees and the flicker business, that these little guys have been almost ignored (not really, but relatively). Anyway, they should be fledging any day now, too, but without all the fanfare. One interesting thing to note with these nuthatches, is that there are nuthatches nesting in the nest box I installed at the 8th Street Pocket Park, which is just a block away. Every so often these two nuthatch factions defend their little territories, which is kind of neat.

Northern flickers

Wow, they have had an eventful spring. Here is a little story of their spring...

• They excavated out nest box
• They also excavated a cavity in a silver maple in front of my neighbors house
• They laid eggs in the cavity in the maple
• European starlings evicted them from their nest
• The starlings are nesting in the tree
• The flickers left the area
• Last weekend the flickers returned to the nest box, and as of yesterday (June 3)have laid at least 2 eggs (in the photo below- kind of poor qualiy but it is a video capture).

I hope they can raise a clutch- it is getting late for them.

Once the chickadees fledge we will switch to the flickercam for nest box viewing. Exciting.

The flickers are not nesting in the garden...

The flickers are not nesting in the garden...and I couldn't be happier. A puzzling statement to be sure, so let me explain...

We began about 10 years ago with nest box for northern flickers. These common, primary cavity nesters are facing many problems from loss of nesting habitat to pressures from invasive species (see here). In order to address the first issue we set up a nest box. This was very successful and effective, and based on how quickly they found the box and occupied it, it is obvious they are looking for, and are limited by, places to nest.

In front of my neighbor's house are decadent silver maples (see above), that you'd think would offer great nesting habitat for flickers, and they do, but unfortunately the cavities get occupied by squirrels instead, and have been for the 10 years we've lived beside them.

But it appears that this year the flickers will finally be nesting in one of these decadent trees and I couldn't be happier.

They did excavate our nest box (see photo at the top of the post), and I thought they were going to nest in it. But at the same time, they also excavated a cavity about 30' up one of the silver maples (photo above, arrow acknowledgement: Bike Garden), perhaps our nest box was a back-up for what inevitably happened when flickers tried to nest in the maples- squirrels would occupy the cavity. But maybe not this year.

Unfortunately wildlife gardening in an urban- or sub-urban setting is not just about planting the right plants and putting up nest boxes, unfortunately it is really about introduced pest management. The primary exotic pests here are starlings, house sparrow and squirrels. Controlling pests is not the most glamorous part of having a wildlife garden, but it is perhaps the most important.

In order to combat these invasive species, we have done several things- making the garden less hospitable for them is the first step , but then there is also control, or killing (click here for more information). As far as making the garden less hospitable, that starts with feeders and nest boxes (click here for information about lessening bird feeders), and native plant landscaping (see virtually any post on my blog for this thought!). Both feeders and nest boxes need to be designed for native birds, so no perches, only food they eat, and really very few feeders, and only seasonal ones (click here and here for more information).

Since we stopped feeding with sunflower seeds, we have seen the number of pests decline dramatically in the garden - including US native, but not Montana native, house finches, which essentially disappeared from the yard. In the summer, spring and fall, there is so much natural food, much of which we have planted, feeding is not important and mainly attracts unwanted, or invasive birds and animals, and it also causes unnatural high congregations of birds, that make them susceptible to other pests, like cats (click here for my thoughts on this).

Secondly we only use nest boxes that are appropriate for native species that we are likely to attract, not bluebird boxes for example (read more here).

Third there is control or killing squirrels. In our garden we have a trap set up, and any squirrel I trap, I kill. This started several years ago, and I went from over 200 squirrels/ year down to fewer than 20 last year and this year will be even fewer. As a result, we have seen birds use the garden much more often and differently than when squirrels patrolled the grounds. And most importantly, birds like northern flickers might just nest in natural places now. Like I said, this is the first year that I am thrilled the flickers will not nest in our garden- perhaps the greatest accomplishment in our wildlife garden so far.

Nesting and Nest Box Camera Update

This was an exciting weekend for the nest box cameras. All three of our nest boxes have birds- northern flickers, black-capped chickadees, and red-breasted nuthatches. New this year, the flicker and chickadee boxes have nest cameras, including streaming the chickadee nest cam! The flicker cam will be streaming next. Here is the link to the streaming video of the chickadee box, though not much is going on during the day, but in the evenings and mornings a lot happens.

I installed the cameras and then packed the boxes with sawdust (click here for a description). This weekend, now that the boxes had been excavated, my wife and I focused the lenses and adjusted the camera angles, though based on the quality of the chickadee camera's video, we might need to do some more lens adjustments.

The photo above shows the chickadee nest box, camera, and the freshly excavated cavity filled with moss and squirrel fur. Based on the female's nest construction (see the video below), it looks like she will be laying eggs soon, then the real excitement begins.

Here is link a short video taken this evening of the female burrowing in to the nesting material to carefully create a pocket for the eggs.

Nesting and bloom update

Wow. Things have changed in the garden. I was out of town for week and when I got back I was amazed how quickly things change this time of the year. Suddenly I feel like there is so much to do in the garden, and suddenly I am so far behind. Here is a brief update of the goings on...

It appears that everything has leaves, buds or flowers on it now; below I list what is in bloom.

Nesting Update

• the chickadees are bringing nesting material into their box (click here for my favorite nesting material combo- squirrel and moss).
• The flickers evidently completed the excavation of their box all while we were gone.
• The mystery this year was what was happening in the nuthatch box? The nuthatches "claimed" this box early on, but then some chickadees began excavating it, and pretty regularly. And there was no sign of the pair of nuthatches. Were these the same chickadees that were also going to nest in the normal chickadee box? And who's ever heard of 2 pairs of chickadees nesting the same yard? Craziness- they need a couple of acres because of competition for food. But now, all has been revealed- the nuthatches have returned and they are now nearly completely done excavating their box.

Once they finish excavating they will probably continue their tiny onslaught of my bent willow furniture- shredding off the bark into fine nesting material for their little, freshly excavated cavity. Then they will carefully line to opening of the box with sap- lest I try to get back said components of my bent willow furniture. Order has been restored.
Bloom Update:

Flowering now- arrowleaf balsamroot (Balsamorhiza sagittata ), golden current (Ribes aureum), blue bells (Mertensia oblongifolia ), larkspur (Delphinium bicolor ), Jacobs ladder (Polemonium pulcherrimum), biscuitroot (Lomatium triternatum and L. dissectum), violets (Viola canadensis ) pasque flower (Pulsatilla patens), cutleaf daisy (Erigeron compositus, pictured above), blue virginsbower (Clematis occidentalis, see photo at beginning of the post of the virginsbower on my clothesline), prairie smoke (Geum triflorum), blue eyed mary (Collinsia parviflora, see below- this is one of my favorites, and it makes a nice groundcover), sivery lupine (Lupinus argenteus ), kittentails (Synthyris missurica ), Oregon grape (Mahonia repens ), and many more species flowering every day that it is hard to keep up.

So much to do. Last weekend I removed a little remnant lawn patch that I have had my eye on to turn from lawn to what I call a mowable prairie. In the lawn's place I planted natives that can be mown and maintained- like a lawn was originally intended- a meadow that could be mown to a height that would allow for paths and play areas. Instead of a lawn or a water hungry meadow, I planted this with drought tolerant, trample resistant natives like yarrow (Achillea millefolium ), hairy golden aster (Heterotheca villosa), mixed aster and erigeron species. After planting starts and transplants in the mowable prairie area, I covered the whole thing with mulch, but not just any mulch, gentle reader, a special mulch... this mulch is made from seed heads and flower parts I cut off last fall and kept in a bag out side all winter (cold stratification). Then I carefully (read: not at all) applied it to the surface of the fresh bed. I've found that with hairy golden aster, and my bag of assorted asters (by assorted I mean I can't really tell the difference between most asters and erigerons in my garden), they do great germinating when laid down in a mulch. I have been waiting for rain to do this, and by golly the rain has finally come (hopefully it will continue for a little while).

I did have a chance to also plant my potatoes, beets, peas, and other things I am probably forgetting and I finally built a new raised bed- for onions (see below, with cat guard installed), I moved the hill that was in its place and potted up all the asters and such that were on the hill. Maybe this weekend, I'll plant those potted up plants into the front yard or fill in other places in the yard.

Now I am well on my way to completing my 2010 garden project list (click here for this list). According to the list, the only thing left is making a new composter, but in reality, the list has really grown...

Lots going on suddenly, more updates with pictures to follow, oh and, a new arrival to the garden yesterday, a golden crowned kinglet.

Hummingbirds are coming

The 15th of April does not just mean the open date of spring black bear season in Montana, nor is it just the income tax filing date- to me the 15th of April is a reminder that the hummingbirds will be back soon. Hummingbirds are one of the few birds we set out feeders for. So its time to get them get them ready.

But nearly as important as providing feeders is planting native plants that flower coincidental with their arrival. Here wax currants (Ribes cereum) and golden currants (R. aureum) are the first to bloom, and golden currants (like the one above) are just about to flower in our yard and in Missoula. As a result, these are the most visited by the travel-weary humming birds (click here to read about other non-traditional humming bird plants).

This year, I am excited to have wax currants in our garden; while attending the Calypso Chapter of the Montana Native Plant Society's meeting, I bought three from Catherine Cain of Southwest Montana Native Landscapes and I found out that Kathy Settevendemie of Blackfoot Native Plant Nursery , who was also at the meeting, sells them as well.

The exact date of hummingbird arrival depends on native plants. Hummingbirds follow the blooms of many plant species on their way north to their nesting sites. It is these plants that provide them with the sustenance for their travels and will ensure plenty of food when they court, nest and raise their nestlings. So, hummingbirds are intimately tied to native plants. Just like butterflies, hummingbirds will feed on any flower at certain times, but the timing of the flowering of native plants is critical for them.

Planting firecracker penstemon (Penstemon eatonii), or other commonly described "hummingbird" plants may have little benefit to them (click here for more information and plant selections).

So its time to get those feeders ready, but, more importantly, get those native plants ready!

Oh, since my last post, I noticed that one of my favorites, the blue eyed Mary (Collinsia parviflora)is in full bloom, and so are kittentails (Synthyris missurica).

Early spring wildflowers in our yard

Here's a brief post- a look at what is flowering this week in our garden. Above are shooting stars (Dodecatheon conjugens), dramatic, if not tiny.

Below the prairie smoke (Geum triflorum) is pinking up.One thing I am really happy about is that we have incorporated a lot of diversity in our garden, and by diversity, I don't mean rare plants. Most plants in our garden are locally common and easy to grow. The reason I like this, is that what is flowering in our garden is also in bloom on the hills, forests and remnant short grass prairies around Missoula.

Below the prairie crocus or pasque flower (Pulsatilla patens) is starting to bloom in the shadier areas of our yard.

But in the front prairie, the is a lot more happening. The sagebrush buttercups (Ranunculus glaberrimus), the first to flower are still hanging on...

and so are the aptly named yellowbells (Frittellaria pudica).

I suspect if I looked hard enough, I'd find some lomatium in flower, but why spoil all the surprises in one day.

Soon, however, lots more species will join in the bloom, like bluebells (Mertensia oblongifloia),

larkspur (Delphinium bicolor),

and even arrowleaf balsamroot (Balsamorhiza sagittata), which had a good year last year. Let's hope the seedlings that showed their first leaves last year will be back for another. Then in a mere 5 or 6 six short years, our little prairie will be awash in balsamroot!
