Snow Raptors

A few from a couple snow days this past January. Some of the first outings with the Canon R5. On one day, light levels were quite low and birds were at a great distance. Tried shooting with and without teleconverter to get more light. Difficult circumstances.

Eastern Bluebird Nest – 2021

In the spring of 2021, I finally put up a couple of nest boxes in the yard of the new house. Both boxes were built and gifted by my father, Bart Duncan. Much appreciation! One box was designed specifically for bluebirds and a pair quickly staked their claim. They had an initial successful clutch, fledging three chicks, but on the next attempt, tragedy struck. During my monitoring visit, where there had been four half-developed chicks the day before I found not a single one. I believe the neighborhood racoons made a meal of them sometime during the night, leaving no evidence. It was early enough in the year that I wasn’t surprised that the pair tried again, but what surprised me was that they did not build a nest in the bluebird box, but used a box that was designed for Carolina Wrens that was bolted to the side of our screen porch. It made for some great photo opportunities that I am sharing here. I learned from my mistakes and have installed a baffle around the pole to the bluebird box along with a wire cage over the nest entrance. If a brood predator wants to get at them now they will really have to try hard. I am happy to say that to date, in the 2022 season, the pair successfully fledged two clutches – one of six and one of five chicks. Eleven new bluebirds this year, flooding the subdivision with bluebirds!

Here dad brings a green and juicy caterpillar for one of the four chicks in the box. I realized that this could be a great way of doing an entomological survey of the neighborhood!

Look at the Sweet Phyllaries on that One!

A look at the disk and ray florets of Symphyotrichum patens (late fall aster)

A lot of folks don’t seem to like attempting to identify plants in the Asteraceae family, more commonly known as the asters. This is a very large family of plants and there are definitely many difficult cases out there in terms of identifying. However, with a good dichotomous key, a hand lens and some patience, I think most anyone can have success in learning some of these interesting plants. The key is learning what characteristics are “key.” The group I am featuring here are three members of the Symphyotrichum genus, often referred to as the “new world asters.” Following recent taxonomic revisions, the genus now holds more than 100 species, of which about 25 can be found in Missouri. Most ray flowers are light blue to violet but some can be white or pink as well.

Photographs can be useful when attempting to identify the new world asters. These can be referred to when attempting identification on your own or sending to someone with more expertise on the group. Knowing what to photograph is important.

A good look at the distinctive involucre of Symphyotrichum patens.

First, both sides of the flower, referred to as the capitulum (composite inflorescence) in the asters, is important in making an identification. Photograph the ray and disk florets along with the involucre from the underside should be photographed. The involucre is a protective structure composed of a group of phyllaries (bracts) that can be beneficial in discerning between species. Asters in this group can be distinguished from one another by the number of ray florets per capitulum and the size of the flowerheads 

The growth habit of Symphyotrichum patens.

Two other photographs you will want to take when attempting to ID the Symphyotrichum are of the plant’s growth habit and the leaves – particularly details of how the leaves are attached to the stems. There are usually key differences here that will be useful when making an identification. Unfortunately, I neglected to take closeups of the leaves while working with these three plants in the front yard this past autumn.

The next species I would like to feature is the spectacular Symphyotrichum oblongifolium, or “aromatic aster.” These plants are quite impressive. Pinch them back once sometime in the month of June and they will bush out, forming impressive globes of violet blooms. The accompanying habit photos are from our front bed and is only three plants! Although these plants create enormous amounts of blooms, I find that it is almost too late in the year. Most of the blooms don’t open until well into October. During this time, most of the pollinators that visited these blooms were honey bees, at least in my yard. I think most of the native pollinators had finished their season by this point.

The above images show the growth habit at flowering of Symphyotrichum oblongifolium.

I hope the next couple of images exemplifies how the phyllaries are important diagnostically for identifying these plants whose flowers look very similar when viewed head-on.

The straw-colored disk flowers of Symphyotrichum drummondii will turn maroon to purple in color late in the season.
Symphyotrichum drummondii – named after Scottish botanist Thomas Drummond, who spent time in St. Louis prior to his famous plant collecting trip to Texas in the 1830s.

Finally, the third member of this genus I have tried in the front yard beds is Symphyotrichum drummondii (Drummond’s aster). This one looks a lot different from the other two, not only in the characteristics of the capitulum, but in its growth habit as well. This is much more of a small, dainty plant that is found in open woodlands and savannahs in the northern sections of Missouri.

The Sweetheart

One day I would love to know how many of our moths received their common names. So many of them are interesting and perfect, like this, the sweetheart underwing (Catocala amatrix). In this case, the Latin binomial agrees. Catocala referring to the namesake, hidden underwing and amatrix meaning lover.

This moth was found in Franklin County, MO.

Catocala amatrix (sweetheart underwing) – Hodges #8834

I’m never really fortunate enough to get a good image with their hindwings exposed, but here is a glimpse of the beauty they keep hidden, apparently useful for startling would-be predators upon their taking flight.
