Artistic Safari: The Howard Pyle Studio Group’s Plein Air Adventure

On exhibit October 21, 2023-January 23, 2024

Join us for the Art Loop on Friday, November 3 from 5-7:30 p.m.

Since its founding in 1935, the Howard Pyle Studio Group has played a vital role as a hub for artistic growth and collaboration in the Brandywine Valley, honoring the legacy of American illustrator Howard Pyle. Workshops, classes and events create a supportive environment fostering learning and camaraderie among member artists.

Painting en plein air, or in the open air, offers artists an authentic way to capture nature’s true beauty. The presence of diverse creatures in these landscapes adds depth and interest to the artwork, but they don’t stay still for long!

To overcome this challenge, the museum becomes an invaluable substitute en plein air location for
Studio Group members. Here, carefully recreated natural settings inspire creativity, allowing artists to skillfully depict diverse species on canvas.

About the Artists

My art includes natural and urban landscapes, from the Brandywine Valley and the Southern Appalachian mountains. Whether painting en plein air or the studio, I enjoy combining a variety of natural shapes and elements from nature and other sources. It has been a special pleasure to paint in the Museum of Nature and Science.

Betsy received a BA in Math from the University of Delaware but turned to art shortly thereafter and studied with many local artists. She has been an exhibiting member of the Delaware Foundation for the Visual Arts and is a member of the Studio Group Inc. and the National League of American Pen Women Inc. She has held many offices including president and treasurer.

She has participated in juried shows at Chester County Art Association, Pen Women Biennial Shows, Pen Women National Biennial, Holly Branch of NLAPW in Dover, Biggs Museum of Art in Dover, DE, Delaware Art Museum – as part of the Studio Group Show, and other local venues and received awards.

She specializes in landscapes and portraits.

Painting in the morning or middle of the day has inspired great opportunities each season. Carol continues her impressionistic / expressive style of painting in oil and acrylics. Lovely weather or stormy warnings allow for the changing of the color palette. Carol sets out for en Plein Air invitationals throughout Maryland, Delaware, Pennsylvania, and Washington, D.C.

Beauty of the destinations are reflected in paintings from Chestertown’s – Paint the Town, Brandywine Conservancy, Historic New Castle’s gardens, Bryn Mawr, Kuerner’s Farm, Brandywine River, Laurel Preserve and farmer’s markets. Recently, the artist received an award for ‘Winter Eventide’ in the Artist Magazine’s January 2023 issue. ‘Sunflowers & Blueberries’ was selected as the international cover for the Pen Woman publication.

The artist engages in a series of painting invitationals by: Mid Atlantic Plein Air Painting Association, Historic New Castle Plein Air, Brandywine River Museum, Delaware Museum of Nature & Science, Land Arts Events (Brandywine Conservancy), Chadds Ford Historical Society, Brandywine Valley: Children’s Beach House, Blue Streak, Unionville Arts Gala, Barbara Moore Fine Art Gallery, River Arts in Chestertown, and the Opera House Antiques & Rodney Pratt Framing & Gallery.

I paint because I don’t know how to live without painting. I have been painting ever since I can remember. It is my therapy, my escape, and my world. If I don’t like the world I am in, I can paint a new one for myself. I paint anything; I paint things that connect to me that I feel drawn to – they have a personality, a story, or they just speak to me. I need to capture them on canvas. I am an acrylic painter, but I am always enthusiastic to learn something new. My process is to first make a mess on my canvas, with loads of energy, throwing paint on it and then cleaning it up. While I am cleaning I create my art. I paint with loads of energy and excitement. I do approach the canvas with an idea of what the final painting will look like, but if the painting decides it doesn’t want to go that way I am open to creating a new painting. Some paintings I leave messy. Some paintings I polish. I allow the painting to tell me how it wants to be finished. Every painting is a growth moment for me.

Lithography is my medium.  It is the physical labor of graining the stone, drawing on the stone, and printing to produce an edition of prints that resemble what was drawn, only richer and deeper.

My college education began at Pratt Institute, in Brooklyn, New York, culminating with a BFA from The Maryland Institute, College of Art, in Baltimore, MD, where I studied drawing, painting, and developed into printmaking.   I continued my study of lithography for over 25 years at the Fleisher Art Memorial in Philadelphia, where I now monitor the lithography and etching studios, as well as continue my studies with Tamarind master printer, Peter Haarz.   I am a member of the National League of American Pen Women and the Howard Pyle Studio Group, where I have enjoyed the camaraderie and support of fellow women artists, writers, and musicians.

I love nature and animals and am always looking around me for inspiration. Drawing to me, is about relationships of tones and lines and how they are inked and transfer to beautiful printmaking paper.

Karen Kuhrt is a graduate of Rochester Institute of Technology with a BFA degree. She studied photography with Minor White and painting with Fred Meyer. Karen is a member of the Howard Pyle Studio and the National League of American Pen Women and has a painting in the Pen Women’s permanent collection in Washington, D.C. Her favorite subject matter is landscape, and painting the gardens at Mt. Cuba is always a treat!

My oil paintings express the play of light and shadow on the architectural forms that make up our towns and cities. Having worked and studied as an architect, I am fascinated by the relationship between our built environment and the landscape. I find inspiration in the unique character of our towns in the Delaware Valley and seek to interpret these views in a colorful perspective.

Chester County artist Kathy Ruck’s paintings reflect a strong sense of composition, color and light. Her attention to detail and skilled media technique draw the viewer into the scene.

Working out of her home studio in Landenberg, PA, Kathy paints the beauty of the surrounding areas of Chester County, PA and northern Delaware. She works primarily in watercolors, but also enjoys pastels, oils and gouache.

“I believe that in today’s hectic world it’s important to fill your home with art that will relax your mind and lift your spirits,” says the artist.

Kathy exhibits her work in local juried art shows, having won several awards for her paintings.  Private collectors and corporations own her paintings. Kathy has been commissioned to create paintings for corporations and institutions including DuPont, PNC Bank, Wilmington University,  Wilmington Flower Market Poster and Yellow Springs Art Show Poster. She is a former president of the Delaware Foundation for the Visual Arts, and a member of the Howard Pyle Studio Group and a signature member of the Philadelphia Watercolor Society.

Roberta is a Delaware representational fine artist who enjoys painting landscape and figurative subjects. She works in studio and in Plein air using a variety of mediums but most often works in oil or pastel.  She was raised by parents who were both artists and can’t remember a time when she didn’t love creating art!

Roberta attended college at the Pratt Manhattan Center, and Long Island University where she studied; Illustration, Art Education and Fine Art. She was also honored to be awarded a full scholarship from the Art Students League of New York where she studied; Life drawing, painting and portraiture.

She has worked in the fields of, Illustration, textile design, advertising and art education. In recent years her primary focus has been creating a body of work that is more representative of her personal feelings, impressions and vision of the world around us. This is strongly influenced by her faith and appreciation for nature. Her work has been featured in numerous shows in the area. She is a member of the Art Students League, the Howard Pyle Studio group, and more recently the Painters Folly Studio group.

Painting for me is a way to express the joy and beauty of the world, using light and color to capture a moment in time. My childhood passion for the outdoors and nature are brought into my paintings. The uplifting feeling that nature provides is expressed in every brush stroke, the warmth of the sun, the cool of the shade, the majesty of the trees and the serenity of the sky. Painting in the studio gives me the opportunity to perfect the techniques that I have studied over the years. But even in the studio, I am drawn to the outdoors, the light and promise of another day.

New bird species discovered through scientific collections

Natural history collections are full of surprises, with scientists updating what is known about different species and uncovering new ones.

Dr. Matthew Halley, Assistant Curator of Birds, is the lead author of a recently-published paper that splits the Slaty-backed Nightingale-Thrush (Catharus fuscater) into seven different species and four subspecies — including a newly-described species from eastern Panamá: the Darién Nightingale-thrush (Catharus arcanus).

These genetically distinct populations live in secluded mountain rainforests in Central and South America and began to diverge from each other nearly three million years ago.

The species look very similar to an untrained eye. To document their differences, Dr. Halley and his team sequenced DNA from multiple populations, studied physical features like plumage color, iris color and bill color, and analyzed differences in their vocalizations.

Dr. Halley shared the findings on his Twitter (now X) account. Read on for a summary, along with some of the figures from the paper:

This figure shows the geographic distribution of the C. [fuscater] complex in Central and South America. Lines point to type localities. The variation in shapes denote sampling locations for different molecular data. Shape size is correlated with the number of samples (1–3).

The C. fuscater complex (Turdidae) is composed of several disjunct populations that inhabit cloudy mountain rainforests, ranging from Costa Rica to Bolivia. These birds are diabolically shy and more often heard than seen. Their song is a series of sweet, musical whistles.

The research identified 10 genetically distinct populations that have been evolving independently for multiple glacial cycles. Molecular clock suggests most lineages diverged in early Pleistocene / late Pliocene— ancient lineages with independent evolutionary trajectories.

This figure shows taxonomic variation in the structure of ‘punctuation calls’, visualized in RavenPro 1.5 (Cornell University), recognizing three groups based on shared acoustic structure: (Type 1) pulsed/rippling: C. [f.] hellmayri, Undescribed 1 (now C. arcanus), C. [f.] mirabilis; (Type 2) long/sinuous: C. [f.] sanctaemartae, C. [f.] fuscater, C. [f.] berplepschi; (Type 3) short/simple: Undescribed 2 (now C. o. tenebris), C. [f.] opertaneus, Undescribed 3 (now C. b. nebulus), C. [f.] mentalis.

Populations were divergent in the acoustic structure of three different call types, which are presumed to be innately acquired (i.e., not learned), and there were subtle differences among populations in song structure, which is presumably learned.

This image is a side view of polychromatic adult plumages in C. [f.] mentalis (from left to right): 1, FMNH 433742, a ‘grey’ male with enlarged testes; 2, FMNH 433738, a ‘brown’ male with enlarged testes; 3, FMNH 364458, a ‘brown’ male with testes not enlarged; 4, FMNH 433740, an adult female with an enlarged ovary. Adults of both colour types (FMNH 433742, 433738) were collected at the same site in November

Halley traveled to the American Museum of Natural History, the National Museum of Natural History and Carnegie Museum of Natural History to study their C. fuscater specimens, and borrowed specimens from the Field Museum, LSU Museum of Natural Science, and the Academy of Natural Sciences of Drexel University, bringing them to the museum to look at sexual and age-related differences in plumage color.

This image shows ventral and dorsal views of the adult male plumages in C. b. berlepschi, C. b. caniceps, C. o. tenebris ssp. nov., C. b. nebulus ssp. nov., and C. mentalis.

With a large sample of study skins assembled under one light source (flat panel LED), subtle differences between populations, difficult to appreciate in the field, became easier to notice — Halley scored this variation by comparing the specimens to published color standards.

The taxonomic revision splits the C. [fuscater] complex into seven species, of which one is newly described, and four subspecies, of which two are newly described (C. opertaneus tenebris, C. berlepschi nebulus). New English names were proposed for each species. The seven species are:

Talamanca Nightingale-thrush (Catharus hellmayri) – monotypic – Northern mountains of Costa Rica (Rincón de la Vieja, Miravalles, Tenorio) to west-central Panama (Parque Nacional Santa Fé, Veraguas). (Photo: alchetron.com)
Darién Nightingale-thrush (Catharus arcanus, sp. nov.) – monotypic – E Panama, endemic to Serranía de Majé and Serranía del Darién, from Cerro Azul in the west, to Cerro Tacarcuna in the east
Pirre Nightingale-thrush (Catharus mirabilis) – monotypic – Endemic to Cerro Pirre, Darién province, E Panama. (Photo: ML 242929041)
Cordilleran Nightingale-thrush (Catharus fuscater) – polytypic – (1) C. f. sanctaemartae, endemic to Sierra Nevada de Santa Marta, NE Colombia; (2) C. f. fuscater, Sierra de Perijá of Venezuela, N and E Andes of Colombia and Venezuela. (Photo: ML 206115721)
Trans-Andean Nightingale-thrush (Catharus berlepschi) – polytypic – (1) C. b. berlepschi, W Andes in Ecuador; (2) C. b. caniceps, W Andes in Ecuador, S to NW Peru; (3) C. b. nebulus, ssp. nov., E Peruvian Andes. (Photo: ML 38468741)
Antioquia Nightingale-thrush (Catharus opertaneus) – polytypic – (1) C. o. opertaneus, NW and Central Andes in Colombia, S to Napo, Ecuador; (2) C. o. tenebris, ssp. nov., Río Chinchipe watershed of N Peru and SE Ecuador
Cochabamba Nightingale-thrush (Catharus mentalis) – monotypic – S Peru, east of the Río Apurímac, E to Santa Cruz, Bolivia

Note: Monotypic species are not divided into subspecies. Polytypic species can be divided into at least two subspecies.

World of Discovery series returns

The World of Discovery series is back at the Delaware Museum of Nature and Science.

Join us for the World of Discovery lecture series at the Delaware Museum of Nature and Science. This fall, we welcome scientists from the University of Delaware College of Earth, Ocean and Environment to present an in-depth look at the pioneering research impacting the future of Earth’s ecosystems.

The Complex Past and Future Trajectory of Coral Reefs

Wednesday, November 8 | 7 p.m.

Coral reefs have long been recognized as the “rainforests of the sea,” with fantastic biodiversity and ecological importance. However, they represent a paradox between the long-term success and resilience of evolution and growth over millions of years and an incredibly fragile ecosystem that is losing a global race against climate change and a host of local threats. This presentation will introduce several aspects of the science behind how coral reefs have been so successful, how they are threatened, and how some scientists are racing to understand what can be done to slow and manage the loss of this critically important ecosystem.

Mark Warner is a Professor in the School of Marine Science and Policy at the College of Earth, Ocean and Environment at the University of Delaware. He studied marine biology at Northeastern University and the University of Georgia (UGA), where he received his bachelor’s degree in zoology and doctorate in ecology. After completing a postdoctoral fellowship in plant biology at UGA, he joined the faculty of the University of Delaware in 2001. He is a Fellow of the International Coral Reef Society and has studied the ecological physiology of reef-building corals for over 30 years in many western and eastern Pacific locations, the Andaman and Red Sea, and the Caribbean.

Exploring the hidden lives of sharks

Wednesday, October 11 | 7 p.m.

Sharks capture the public’s attention like no other species, as demonstrated by the popularity of Discovery Channel’s “Shark Week” and the frequency with which stories of sharks “lurking” in local waters grab headlines. However, despite the great public interest in sharks and the important role they play in marine ecosystems, these animals remain misunderstood and challenging to study. Learn how new research is shedding light on the biology and ecology of sharks and how scientists are using cutting-edge technologies to view the hidden lives of sharks and aid in the conservation and management of these iconic predators.

Aaron Carlisle is an Assistant Professor in the School of Marine Science and Policy at the University of Delaware. He has studied the biology and ecology of fishes for the last 20 years, largely focusing on elasmobranch (sharks, skates, and rays) and pelagic fishes (tunas, billfishes).

Sound is a distinct part of an ecosystem. The soundscapes in the galleries are designed to add another level to the immersive experience – they aren’t just background noise! Many of the species that can be viewed in the exhibits have a corresponding sound in the gallery’s soundscape.

In an ecosystem, sounds are part of an animal’s habitat, offering clues about the surrounding environment as well as being a tool to communicate with others. For example, when a hawk flies by and screams, mice and other rodents nearby will scurry away.

Some of the sounds used in the soundscapes came from the Macaulay Library at Cornell University, which features the largest archive of animal sounds in the world, with new material constantly uploaded. For example, the Pileated Woodpecker sound, heard as part of the Regional Journey’s Temperate Forest soundscape, was initially recorded locally and uploaded to the Macaulay Library by Dr. Matthew Halley, the museum’s Assistant Curator of Birds. These resources help power Cornell’s Merlin app, which can be used by bird watchers in the field to identify birds by photo and sound.

Listen to Dr. Matthew Halley, the museum’s Assistant Curator of Birds, talk about the soundscapes in the Regional Journey Gallery and what we can learn from the sounds we hear.

Transcript: Regional Journey Soundscapes

Hi. Welcome to the Delaware Museum of Nature and Science Regional Journey Gallery. My name is Matthew Halley, and we’re going to talk a little bit about the soundscapes that we hear today in our gallery.

We’ve got multiple habitats that are found in the mid-Atlantic region, a deciduous forest, temperate forest habitat. We have the Delaware Bay and salt marshes and the cypress swamp, and each of these habitats has a different soundscape.

We hear different animals and different crashing waves or the rustling of the leaves. There’s all sorts of sounds that are happening in nature.

When we go into these habitats and the animals are calling out for different reasons that scientists like to argue about, about whether they’re saying, here I am, here I am, or they’re staking a claim to a certain area and resources, or maybe they’re trying to attract a mate or attract some companions.

But regardless of the reason, these animals have to live in a in a soundscape and they listen to all these different sounds and they react to the sounds in their life, which helps them to survive. And when the hawk flies over and gives its scream, you can be sure that the mice that are under the hawk are scurrying into a safe corner.

So, birds make different kinds of sounds and scientists call them calls or songs. But we don’t have any clear-cut definitions for those words. Some sounds are shorter and less complex, such as when a Blue Jay goes “jay…jay.”
Other songs are a lot more complicated. When the robin is singing, it’s warbling song going on and on. It seems like it doesn’t repeat itself very often.

And then we have the mockingbird, which, you know, can go on for an hour, and we don’t hear anything from the same. You know, it’s constantly coming up with new syllables in its song so that we might think of that as kind of a gradient of complexity in bird vocalizations. And one of the things that some that scientists have figured out is that some vocalizations are learned and other vocalizations seem not to be learned.

So, the Phoebe that makes it’s Phoebe, Phoebe call that will develop normally in a baby Phoebe, without hearing an adult. If it grows up in an acoustic isolation chamber, that little Phoebe is still going to say “Phoebe, Phoebe.”

And it’s going to be indistinguishable from a baby Phoebe that grew up in a forest full of Phoebes.
But some other songs: here we’ve got the wood thrush singing in the soundscape, the wood thrush, that flute section in the middle of its song. When you raise a wood thrush in isolation that’s middle, part of the song gets kind of flat and unmusical. And so, it seems that the wood thrush needs to grow up around other wood thrushes to have a tutor to learn how to sing its song correctly.

And when I say correctly, I mean just to sing to produce a normal song that will achieve the functions of the song, whatever they may be, whether it’s territorial defense or attracting a mate. The more your song deviates from the normal, that might have an effect on whether you’re successful surviving or reproducing.

Regional Journey

Four rotating soundscapes in the Regional Journey feature many of the birds seen in the exhibits. Listen closely: there’s also a frog, squirrel, and a fishing reel!

Global Journey

In the Alison K. Bradford Global Journey Gallery, soundscapes including a variety of birds, mammals, and insects rotating through the land-based ecosystems.
