Australia - Birds of the Blue Mountains and Sydney
A recent trip to Sydney and the nearby Blue Mountains region with the family provided the opportunity to explore the ways that Australians are promoting habitat gardening and biodiversity in this region.
We stayed at a lovely AirBnb in Leura, NSW, in the Blue Mountains. Most of this area is a massive wildlife reserve and is rich with biodiversity. The variety of birdsong, especially in the mornings, was amazing. Here are a few of the ones that we captured on camera, though we could hear hundreds more. They are the most active before dawn and at dusk, so images were hard to capture. If you go, I highly recommend staying in a place that has an adjoining wild space so you can fully experience the wildlife here.
Grandson, Charlie, took a picture of this red and green King Parrot in the back yard:
At a lookout near Leura, I saw these beautiful birds but have not yet identified them.
We returned from a long walk along Lindeman Road to find Crimson Rosellas in the garden at our AirBnb. This one perched in the same quince mentioned earlier.

It's Working! The Leafcutter Bees Have Arrived!
At last! We have leafcutter bees in our garden! We have been busy and traveling, so did not actually see them take some of these leaves for their nests, but we are so happy to see that they have found our garden in any case. We're watching for them now, noting that leafcutter bees are striped like a honey bee, but carry pollen on their abdomens (see image below).
They are solitary bees that cut circular pieces of leaves from plants such as Western redbud, rose and azalea. They then use these pieces to line their nest and also plug the spaces between their egg cells. You can find them nesting in wood, hollow stems from plants, or in other natural cavities. It is easy to encourage them to nest in your garden by providing them with some of these natural materials or even a 'bee hotel': https://beegarden.ucdavis.edu/wp-content/uploads/2018/04/How-to-build-and-use-bee-blocks.pdf
California is home to over 1,600 species of native bees - more than any other state. These bees have evolved to specialize on certain native plants, and play unique roles in our complex ecosystems. Learn more about the types of bees here: https://arboretum.sf.ucdavis.edu/blog/beyond-honey-bee-learn-more-about-california-native-bees
I hope you'll be inspired to grow some native plants to benefit these amazing beneficials!
Happy (native) gardening!
Jennifer
Remember: Never use pesticides. Even the organic ones kill bees that pollinator our plants. Encourage your neighbors to stop using pesticides that will kill your butterflies and bees when they visit those gardens as well. Avoid herbicides which will damage the ecosystem you are trying to build, and pose health risks for humans, too.

Grow Caterpillars, Feed Baby Birds

Our local birds are in serious decline. The adult birds that are visit our feeders in fall and winter will start nesting in early spring. When they do, they will seek millions of caterpillars to feed their young. That’s right – the babies don’t eat seeds. Their throats are tender and they need thick, soft, nutritious caterpillars (think of them as ‘sausages’ for baby birds). But caterpillars are increasingly rare, and many of our local baby birds face starvation each spring. How can we save them?
Caterpillars grow primarily on native plants like the ones listed here: https://bit.ly/Feed-Baby-Birds. Just as monarch caterpillars need native milkweed, checkerspot caterpillars need bee plant (scorophularia californica) and monkeyflower, acmon blues need buckwheat and lupine, sphinx moth caterpillars need clarkias.
In short, we need to grow the plants that grow the
caterpillars that grow the baby birds. Here
in the SF Bay Area there are several hundred native butterflies and moths that
specialize on particular native plants (see item #3 below), let’s get started
and grow them!
Five Ways to Save Baby Birds in the Spring (start now!)
1) Read:
If you have just 10 minutes, read this New York Times article about the
issue and solution: If https://bit.ly/Chickadees-Guide
2) Watch: Check
out this talk by New York Times Bestseller Doug Tallamy, who wrote “Nature’s
Best Hope” that will inspire you to grow caterpillars: https://bit.ly/Tallamy-CAPlants
3) Plant: Whether you have a garden or simply a balcony with a pot of soil, you can start growing ‘baby bird food” in the form of caterpillars.
Here is a super-colorful guide to the "Fabulous Fifteen" - the very top performing California natives that will provide the greatest number of caterpillars in your garden: https://bit.ly/Feed-Baby-Birds
You can find a longer list here: https://bit.ly/Tallamy-Bay-Area-Natives and then learn more about the plants here: https://bit.ly/Calscape.
See the Audubon Society’s database of plants
that provide insects, berries and seeds for adult birds: https://bit.ly/Native-Plants-Audubon-USA
4) Share:
In just a few moments each day, you can share information, native plants and
native seeds with friends and neighbors. Build a “butterfly corridor” in
your area. Butterflies, moths and bees sense plants by the natural chemical
compounds those plants emit, so patches of plants spread over an area will
“send out a signal” and draw them to your garden!

Remember: Never use pesticides. Even the organic ones kill caterpillars that feed baby birds. And even aphids serve as baby bird food, so try to leave them on your plants as much as possible. Encourage your neighbors to stop using pesticides that will kill your butterflies and bees when they visit those gardens. Avoid herbicides which will damage the ecosystem you are trying to build, and pose health risks for humans, too.
Easy To Grow California Native Plants That Feed Caterpillars (that feed baby birds):
As mentioned above, you can click on this handy guide with interactive links to the TOP 30 California native plants that support the most caterpillars. Most of these are drought resistant, many are evergreen, all of them are beautiful and will dramatically increase biodiversity in your garden:

These plants also provide nectar and pollen to butterflies,
Moths and Bees
Details: The interactive guide enables you to click the plant name to see some of the butterflies and moths that lay their eggs on them (and be sure to choose the variety that grows naturally in your area, using the Calscape.org address field).
The titles
also include generic name, Latin name, precise species and total number of
butterflies and moths that lay their eggs on them per Doug Tallamy,

Grow Wildflowers, Grow Butterflies and Moths - Wildflower Packet Info for a Sunny Wildflower Mix
Free Wildflower Seeds!
Sometime in November 2021, I stumbled upon a simple model for inspiring people to try native gardening - give away free seeds, and leverage social media in the process. In the beginning, I simply gave away seeds to friends, family, and people on my block. But the most successful seed giveaway was on Nextdoor, which made distribution easy (I'd drop off seeds at a Little Library near my house or mail out to people). The seeds were popular but by themselves were not going to inspire people to create habitat gardens. So, I included a handout (below) with the images and info below, and also invited people to join the "Bring Back Bay Area Bees, Butterflies and Birds." group that I started on Nextdoor. I heard from many people that they found the resources very useful. And, within 8 months, over 325 people had joined the Nextdoor group and started sharing plants, seeds and tips with each other.

Planting instructions
Fall through winter is the ideal time to start growing California native wildflowers as these have adapted to capitalize on the fall and winter rains (October-February is best).
Choose A Site & Prepare Your Soil. Choose a spacious site in full sun. Prepare your soil (or several very large pots), by removing all existing growth and debris. If your soil is clay, break it up with some compost or cactus soil (sold at nurseries).
Water thoroughly to help seeds settle into the soil. Continue to water a few times a week, unless it rains, so they don’t dry out after germinating.
After you plant your seeds, let the area ‘go natural’ by leaving the leaf litter on the ground. While many butterflies go into chrysalis on stems or other hard surfaces like branches, many others go into chrysalis in the debris. If you rake or blow it, you could accidentally throw them away. Use stepping stones so that you won't crush native bees and other insects that will set up their homes underground as you develop habitat.
Avoid using pesticides anywhere in your garden, it will kill the beneficial insects such as bees, butterflies, moths, and ladybugs that you are trying to attract. Try to ignore bugs, as they are part of the ecosystem (for instance, hummingbirds eat aphids). If you hose the plant or try to remove pests you may dislodge butterfly or ladybug eggs or kill tiny caterpillars. Avoid using herbicides as they also poison the ecosystem you are trying to nurture.
