The Eastern Screech Owl, Megascops asio, is one of North America’s most common yet most variable owls. This little 6 to 9 inch owl can be red, grey, brown, or a combination — with varying amounts of white as well! Screech owls are nocturnal carnivores that live in open forests throughout the eastern half of the United States and neighboring areas of Canada and Mexico.
Like other deciduous larches, the subalpine larch, Larix lyallii, sheds its needles each year. The trees make a grand show up there near the treeline, with their yellow needles and often twisted form. Further down the mountains, they tend to be taller and grow straighter. Fresh new twigs have single needles, whereas older twigs have clusters of needles growing from a little raised knot along the twig. Cones are spherical with long bracts extending out past each scale, giving the cones a shaggy appearance. These trees grow along with their very close and very similar relative, Larix occidentalis, in the upper Rocky Mountains and Cascade range in the northwestern United States and nearby regions of Canada.
Kenilworth Ivy or Ivy-Leaved Toadflax, Cymbalaria muralis, was originally native to Mediterranean Europe but has been naturalized to the UK and parts of the USA for hundreds of years. It is widely planted in rock gardens and along garden pathways. This hardy snapdragon-like plant is an edible and a Stepable Plant that matures to just a few inches tall, but is often found creeping along or cascading over a stone wall or ledge, the whole plant being several feet long. The purple toadflax-like flowers have two lips with bright yellow spots on the lower one. Flowers draw back into the soil or rock crevice once fertilized.
Common Heather, Calluna vulgaris, is a dominant plant in European moorland, and can also be found in some bog areas and pine forests. This hardy species of heath has come to be naturalized in parts of North America and Asia and is often cultivated in rock gardens around the world. There are close to 1000 different cultivars of this once-humble species, varying in growth form, flower color, flowering time, and other features. The natural species has tiny scale-like leaves and mostly pink flowers, and blooms in late summer.
Native Americans used the peeling bark of the paper birch, Betula papyrifera, as a waterproof covering or even container (such as a drinking cup or ladle). This hardy tree forms beautiful stands of white-bark trees from the southeast United States, across to Alaska. It is absent from the southwest, but extends far north into Canada. The serrated edge leaves appear alternate on the branches — or in groups of 2 or 3. In the spring, the dangling male catkins are about 3 inches long, female about half that length. The tree produces winged fruits in late summer or early autumn.
The American Goldfinch, Spinus tristis, is one of North America’s last birds to get started building a family. In July, when other bird families include fledglings aplenty, the thistles are just starting to bloom. This signals the conspicuous bright yellow male goldfinch and his olive colored mate to start building a nest, constructed mostly of thistle down. When the eggs finally hatch, the thistles have gone to seed — the perfect time to start feeding chicks! Parent goldfinches serve their nestlings a milky cereal-like substance made of thistle seed — the bird world’s closest thing to mammal milk!
The American Bittersweet vine, Celastrus scandens, is native to central and eastern North America, but is unfortunately being replaced by a non-native invasive species, the Oriental Bittersweet, Celastrus orbiculatus. Our native species has alternate, oval, fine-toothed leaves and berry-like fruits that start out green, change to yellow then orange, then finally split open to reveal the 3-part fruit interior shown below. The fruits are poisonous to humans but eaten widely by birds and mammals, from wild turkeys to eastern cottontails. When growing up a young sapling, bittersweet vines can choke out and even kill their host, but typically it causes no real damage.
The stickpins or stubble lichens are 30 species in the genus Calicium, which often grow on live branches of trees such as giant redwoods. Below is a closeup of the fruiting body of Calicium adaequatum, sometimes called the “tiny daisy” lichen. Click the links below the pic to see just how minute these bodies really are…! Our Creator sure likes to put a lot of detail into tiny structures! 😀
Two days in a row, when I went to my mailbox there was a Zelus nymph — a young assassin bug — on the handle. Each time, I gently lowered the door on the box, trying not to disturb the unique creature that graced my front yard. Each day, it was a different species, too! One day it was the red one shown below, Zelus longipes. The other day it was a smaller, little green guy, Zelus luridus. While some say they look like their adult forms (due to incomplete metamorphosis), I could not find these nymphs in any of my insect books because there is no ADULT insect that has this body shape. My research began by googling “skinny bug”! 😀

Most red-eyed vireos (Vireo olivaceus) breed in North America and overwinter in the Amazon basin of South America. During the breeding season, a single male may sing constantly, up to 10,000 times each day! Because of this and their canopy-feeding lifestyle, these little birds are often heard rather than seen, and their song is part of most forest soundtracks. If you can zoom in on an adult, you may be able to see its bright red eyes, but most commonly you will have to settle for its song and its olive green body with grey, black, and white head pattern for identification.
The crown-tipped coral fungus is white to yellowish and about an inch or two tall with little spikey crown-shaped tops on its “branches”. It grows on long-dead wood in North America and is edible, with a peppery taste that tends to disappear when cooked. The video below describes where to find this fungus species, how to identify it, and how to harvest and cook it. The links below the video feature more pics and species information.
