A Backyard First!

Red-breasted Nuthatch

I’m so glad I spent some time at home this afternoon. This gave me the opportunity to find the first Red-breasted Nuthatch that I have found visiting our backyard feeders. I so wanted to some how tell this little one that I would have seed available all winter long as it consistently went back and forth from the big oak to the feeder, each time carrying a sunflower seed to hide in the bark. I am pretty certain that this bird visited the feeder more than 50 times in the couple hours I watched.

Making the Birds Earn their Supper

White-breasted Nuthatch

I have been given a lot inspiration lately by a number of Facebook friends to photograph the great birds that visit our feeders, or to put it another way, make these models work for their supper. On a recent birding trip, Sarah and I collected some great drift wood that I turned into horizontal and vertical branches in the backyard, not too far from the feeders and our sun-porch.

Dark-eyed Junco

I drilled a few extra holes towards the rear of some of these to act as unseen cavities to place my homemade bark butter. It only took the Juncos a couple of hours to find their favorite food. These guys go crazy trying to figure out how to get to this stuff. I made sure to place a few feeding spots near horizontal perches that they could access without too much difficulty as they cannot grasp vertical perches very well. These guys are so tame that they were my primary subjects, other species being a little more timid to visit the close perches and seed deposits that I sat close to.

For a first attempt, I’m pretty pleased. These were shot hand-held in mixed lighting with my 100-400 mm lens and I shot through the not-so clean windows of the sun-porch. I tried sitting behind the open windows, but this must have made me much more conspicuous. I sat for an hour or more with few birds coming in to feed. Within seconds of me closing the windows, the Juncos came to the feeding stations.

Downy Woodpecker

I’m a little concerned that my resident Downy Woodpeckers might have a little too much of the rich food I am providing. They now have access to the peanut and tree nuts in the no-mess mix I provide, beef tallow suet blocks, and now the bark butter. But, I suppose it would take a lot for a wild bird to over indulge.

Anyone who feeds their wild birds and has an interest and access to photography should give this a try. I’m looking forward to more cold mornings spent outside trying my hand at this.

Back to the Prom

A Wilson’s Promontory Hillside at Sunset

It has been a while since I’ve shared some photos from Wilson’s Promontory National Park, along the southern coast of Victoria, Australia. This is definitely one of my favorite places I have ever visited and today I want to tell an ecology story of a special plant that I had no idea existed until making this trip in December, 2017.

Sawtooth Banksia (Banksia serrata)

The Banksia are a highly adapted plant that are found along a number of coastal habitats surrounding Australia. Wilson’s Promontory has four recorded species, two small to medium tree type forms, Banksia serrata and B. integrifolia and two smaller brush/shrub forms, B. marginata, and B. spinalosa (1). The most abundant species on the Prom and the only one I had sense in taking photographs of is the sawbank banksia, B. serrata. 

Current (sides) and past (center-back) year’s inflorescence of Banksia serrata

Banksia are easily identified by their bottlebrush-shaped spike inflorescence, which can contain hundred to thousands of of tiny flowers. Typically, only a few flowers will produce a hard and woody follicle that may hold the seed enclosed on the inflorescence “cone” within the canopy for as many as ten years. Although hard fires will cause the death of established Banksia, it is a necessity for most Banksia to remain stable in their habitat. Wild fire causes the woody follicles to dry and allows the opening of the hinges that releases the seeds within and promotes their germination (2).

The photo below shows a very old “cone” that is still being held on the plant despite the seed having been released due to fire-induced desiccation.

The Banksia are well-adapted to fire as the next photo attests. Collin and I found this recent cut along a trail access. The thick and furrowed bark helps to keep fire from destroying living cells underneath.

There is a great case for describing Banksia as mutualist keystone species. Nectar produced at the base of the flowers was used by original native peoples, the Gunna and the Boonwurrung, to sweeten their water. This nectar also feeds a wide variety of important insect and bird pollinators during the day and mammals, like the eastern pygmy possum, at night. Birds such as Spinebills, Wattlebirds and Lorikeets have tongues adapted with brush-like tips that helps them specialize in feeding primarily on nectar and pollen (2). The photo below shows a Rainbow Lorikeet that I was able to capture in the act of feeding.

Only the largest of seed-eating birds, like the Yellow-tailed Black-Cockatoo, can use their strong curved beaks to break into the woody seed pods of Banksia to feed on the seeds within.

Yellow-tailed Black-Cockatoo (Calyptorhynchus funereus) are one of only a few potential bird species that can prey on Banksia seed on the Prom

B. serrata and B. integrifolia are among the tallest of trees in heathlands and similar habitats where they are found in the Prom. Because of this, they are important architecture for perching and nesting birds as well as providing shelter for small mammals. This male Fan-tailed Cuckoo is one of a few birds we found using the Banksia.

Until next time, have a good day, mate.

 

 

 

You Have to Look Under a Lot of Leaves to Find a Slug

Pin-striped Vermilion Slug Moth – Limacodidae – Monoleuca semifascia (4691)

The WGNSS Nature Photography Group met on September 1, 2018 at Don Robinson State Park in Jefferson County, MO, with the goal of finding slug moth caterpillars and whatever other macro subjects of interest we could find. Overall, I think we had good fortune on this hot and muggy, late-summer day, finding quite a few interesting caterpillars. The slug moth caterpillars were a little scarce, but we did find a little something extra special – the pin-striped vermilion slug moth (Monoleuca semifascia) (Hodges # 4691). In four summers of looking for slug cats, this is the first one I have seen. It is a southern species and I assumed it would need to be found in the south-western part of our state where the open barren woodlands and savanna type environments this species prefers are more common.

This is the 14th of 15 species of slug moth caterpillars that are found in Missouri that I have been able to see and photograph. One more to go!

Slug cats can be found on virtually any species of woody plant in the state. Although oaks and hickories seem to be the preferred host plants, this animal was found on an eastern redbud (Cercis canadensis).

I hope these photos make it obvious why hunting these cats can become quite addictive.

In Search of a Rare Gem

Hine’s Emerald Dragonfly – Corduliidae – Somatochlora hineana

Ever since I heard that a number of newly identified populations had been discovered in Missouri, I have been wanting to find the Hine’s Emerald Dragonfly (Somatochlora hineana). I’ve gone a time or two on my own in previous years, but without specific knowledge on the where’s and when’s to find the flying adults. On June 16th, 2018, the Webster Groves Nature Study Society’s (WGNSS) Nature Photography Group headed to what might be the largest population of this species in the state. Thanks to WGNSS member and photographer, Casey Galvin, we were allowed access to a privately held farm in Dent County, MO that holds this population.

Hine’s Emerald Dragonfly – Distinguishing characteristics

So, what is a Hine’s Emerald Dragonfly and what distinguishes them from the other 24 or so species in the Stomatochlora genus, or the “striped emeralds”? The above photo shows these distinguishing characteristics. Beyond the obvious emerald green eyes that all of the striped emeralds possess is the pair of yellow thoracic stripes on the sides of this species. Another and more diagnostic is the particulars of the genitalia. Using a good field guide will easily allow you to come to a species.

Hine’s Emerald Dragonfly – Finally at rest

Currently on the endangered species list, S. hineana was thought extinct as late as the mid 1900’s. Current populations of this species are now known from the states of Illinois, Wisconsin, Michigan and Missouri. Current population estimates indicate that there are approximately 30,000 individuals in the world. About 20,000 of these are believed to be in the species stronghold of Door County, WI. Like many of the striped emeralds, S. hineana has specific habitat requirements. The preferred habitat for this species is fens and sedge meadows overlying dolomite bedrock. Habitat loss, pesticide use and changes in ground water are identified risk factors affecting the Hine’s Emerald.

Hine’s Emerald Dragonfly – A photographer’s potential nightmare

Like many dragonflies, S. hineana is a sun-lover, active in the early parts of a June morning before things get too hot and he finds a hidden perch. Until then the males are airborne, patrolling their territory in the hopes of finding a female or a male to chase away. The photographer need be patient and wait for the opportunity when the insect stops to hover in the same general place. This is the split-second opportunity that you wait for. The problem is that autofocus is of little to no help. I primarily used manual focus on the in-flight shots.

Hine’s Emerald Dragonfly – A worthy pursuit

There were plenty of opportunities for the patient photographer and observer. Often, an individual would fly so close to the lens we were sure it would use it as a perch. At these distances any movement by the dragonfly would throw it completely out of focus, so the photographer is looking for the sweet spot – close enough to be large in the frame, but far enough to enable tracking.

Hine’s Emerald Dragonfly – A rare gem

It was such a thrill to finally be able to meet these guys. With this location and up to 20 others, it is nice to know that Missouri is home to such a rare gem. Hopefully it will remain so.

Finding Snow in April

Snowy Owl – BK Leach Conservation Area

A huge thank you to Danny Brown, without whom I most likely would have stayed at zero Snowy Owls for the great Snowy irruption of the 2017/2018 winter. Because of travel and just poor luck, I had missed out on finding the Snowy Owls that had salted the state this winter and would never have imagined that we would have another chance a week into April. But, since the weather to date  suggests little of spring, I suppose we should have not been too surprised.

Snowy Stretch

The birding on Saturday was seemingly great everywhere and Steve, I and others were having good luck finding interesting species at RMBS when we received the messages from our phones about Danny’s find. I think Steve and I would have been satisfied with our usual views from a football’s field or two away, but were ecstatic to find the bird perched at an optimal viewing distance, resting after a nice meal that others had documented earlier in the day.

Snowy Yawn

We left the bird still on its perch shortly after sunset. On the way out of the conservation area we had a Short-eared Owl and American Bittern flyovers. Thanks again, Danny.
