About Richard Timm |
While his now widely acclaimed paintings are completed in the studio of his Trenton, Michigan home, Timm travels his home state and beyond doing his research; sketching and studying his mammal and bird subjects in their natural habitats, acquainting himself with their habits and even the psychology and feed preferences. As a onetime avid hunter himself, Timm spent countless hours in the fields and forests, marshes and swamps and in duck blinds beside the waters of Michigan, Canada and as far west as the Rocky Mountains. Now, his collection of fine long guns is left at home as Timm arms himself with the sketchpad and with the same enthusiasm, seeks out subjects for the easel rather than the table. Returning some of what he has taken from the wild, both as hunter and artist, Timm “gives back” in contributions of art for re sale to sportsmen’s and environmental groups. An active member of Ducks Unlimited, he regularly donates his art to support the campaign of that organization for the conservation and propagation of America’s waterfowl. Recently Timm was commissioned by GMC Truck and Bus Group to do a painting for the Ducks Unlimited wildlife organization. This painting will be a limited addition collector’s print. Five thousand of these duck prints will be produced, signed, and numbered. GMC Truck will donate these collector prints to Ducks Unlimited on the occasion of their 50th Anniversary. The collector prints will be used by Ducks Unlimited to raise funds for the preservation of the wetlands, which present the future generations of people may enjoy. The love of the outdoors and its creatures was first instilled in Richard Timm by his uncle, Arthur Lambka, with trips to Michigan’s nature rich Upper Peninsula which remains largely unspoiled by incursions of man. Formal art training for Timm, a native of Detroit suburb of Lincoln Park (as is his wife, Frances), began at the Meinzinger Art School, Detroit, and proceeded to the Art Center in Los Angeles. Painting and carving of wildlife was a hobby throughout a 20 –year commercial career, principally in the auto industry, but for a time in the aircraft industry following Timm’s study in Southern California. Timm’s accomplishments also include winning the 1978 Michigan Duck Stamp; 1982, Nevada Duck Stamp and the 1989 Alaska Duck Stamp. He has been a finalist in the Federal and many state Duck Stamp contests. In 1990 - 1998 he has been 2nd in the Florida Duck Stamp Competition. The Mammals of North America, a large and complete collection of quadrupeds, which range in size from chipmunks to the Kodiak bear, is Timm’s best-known work to date. Timm has an extensive waterfowl collection which include: the Waterfowl of North America and a six work series of the majestic Geese of North America. Fittingly, the first of the latter series depicts the Canada Goose, most regal of that species. While Timm certainly is a master of oils, and frequently employs watercolor, his favorite medium currently is acrylics. As an artist, Timm strives to accomplish three things in all his paintings. “I try to paint authenticity, realism, and a natural habitat,” he says. As a result, Timm’s paintings reflect natural real-life scenes which are highly detailed. And there is usually that special added touch of a chipmunk or butterfly that seems to draw the attention of the subject, as in his painting of the “Labrador Family,” a technique that Timm employs to help describe the habitat. His paintings are exhibited and sold in prominent art galleries throughout the United States. |
Turning his back on the security of a successful career in commercial art, Richard Timm in 1971 decided to devote his considerable talent to his former avocation of wildlife art. Apparently, the decision was a wise one; within a very few years of the beginning of his career, his prints and single works are sought after both by collectors and casual admirers both for aesthetic pleasure and investment value.Hoary marmot

The Hoary marmot (Marmota caligata) is a species of marmot that inhabits the mountains of northwest North America. Hoary marmots live near the tree line on slopes withgrasses and forbs to eat and rocky areas for cover.
It is the largest North American ground squirrel and is often nicknamed "the whistler" for its high-pitched warning issued to alert other members of the colony to possible danger. The animals are sometimes called "whistle pigs". Whistler, British Columbia, originally London Mountain because of its heavy fogs and rain, was renamed for these animals to help make it more marketable as a resort.[3] The closest relatives of the species are the yellow-bellied, Olympic, and Vancouver Island marmots, although the exact relationships are unclear.[4][5]
Description
The hoary marmot is a large, bulky, ground squirrel, with short, heavy limbs, and a broad head. Adults range from 62 to 82 cm (24 to 32 in) in total length, including a 17 to 25 cm (6.7 to 9.8 in) tail. The species is sexually dimorphic, with males being significantly larger than females in most subspecies. Because of their long winter hibernation, during which they survive on fat reserves, the weight of the animals varies considerably over the course of the year, from an average of 3.75 kg (8.3 lb) in May to around 7 kg (15 lb) in September, for a fully grown adult.[6] A few fall adults can weigh up to 10 kg (22 lb), with exceptional ones attaining 13.5 kg (30 lb).[7] It is reportedly the largest member of the squirrel family, though the slightly lighter alpine marmot is sometimes titled this as well.[8]
The word "hoary" refers to the silver-gray fur on their shoulders and upper back; the remainder of the upper parts have drab- or reddish-brown fur. The head is black on the upper surface, with a white patch on the muzzle, white fur on the chin and around the lips, and grizzled black or brown fur elsewhere. The feet and lower legs are black, sometimes with white patches on the fore feet. Marmots have long guard hairs that provide most of the visible colour of their pelage, and a dense, soft underfur that provides insulation. The greyish underparts of the body lack this underfur, and are more sparsely haired than the rest of the body.[9] Hoary marmots moult in the early to mid summer.[6]
The feet have slightly curved claws, which are somewhat larger on the fore feet than on the hind feet. The feet have hairless pads, enhancing their grip. The tail is long, slightly flattened, and covered with dense fur. Apart from the larger size of the males, both sexes have a similar appearance. Females have five pairs of teats, running from the pectoral to the inguinal regions.[6]
Distribution and habitat
The hoary marmot inhabits mountainous environments from sea level to 2,500 metres (8,200 ft) elevation, through much of Alaska, western Canada, and the extreme northwest of the contiguous United States.[1] They live above the tree line, at elevations from sea level to 2,500 metres (8,200 ft), depending on latitude, in rocky terrain or alpine meadows dominated by grasses, sedges, herbs, and Krummholz forest patches.[6] Fossils are known dating back to the Pleistocene, including some from islands no longer inhabited by the species.[10]
The three currently recognised subspecies are:
- Marmota caligata caligata – Alaska, Yukon, NW Territories, northern British Columbia
- Marmota caligata cascandensis – Cascade Mountains, from British Columbia to Washington
- Marmota caligata okanagana – Rocky Mountains, from Yukon to Montana and Idaho
Behaviour and diet
Hoary marmots are diurnal and herbivorous, subsisting on leaves, flowers, grasses, and sedges. Predators include golden eagles, grizzly and black bears, wolverines, coyotes,red foxes, lynxes, wolves, and cougars. They live in colonies of up to 36 individuals, with a home range averaging about 14 hectares (35 acres). Each colony includes a single, dominant, adult male, up to three adult females, sometimes with a subordinate adult male, and a number of young and subadults up to two years of age.[6]
The marmots hibernate seven to eight months a year in burrows they excavate in the soil, often among or under boulders. Each colony typically maintain a single hibernaculumand a number of smaller burrows, used for sleeping and refuge from predators. The refuge burrows are the simplest and most numerous type, consisting of a single bolt hole 1 to 2 metres (3 ft 3 in to 6 ft 7 in) deep. Each colony digs an average of five such burrows a year, and a mature colony may have over a hundred. Sleeping burrows and hibernacula are larger and more complex, with multiple entrances, deep chambers lined with plant material, and stretching to a depth of about 3.5 metres (11 ft). A colony may have up to 9 regular sleeping burrows, in addition to the larger hibernaculum.[11]
Many forms of social behaviour have been observed among hoary marmots, including play fighting, wrestling, social grooming, and nose-to-nose touching. Such activity becomes particularly frequent as hibernation approaches. Interactions with individuals from other colonies are less common, and usually hostile, with females chasing away intruders. Hoary marmots are also vocal animals, with at least seven distinct types of calls, including chirps, whistles, growls, and whining sounds.[12] Many of these calls are used as alarms, alerting other animals to potential predators. They also communicate using scent, both by defecation, and by marking rocks or plants using scent glands on their cheeks.[6]
Hoary marmots frequently sun themselves on rocks, spending as much as 44% of their time in the morning doing so, although they will shelter in their burrows or otherwise seek shade in especially warm weather. They forage for the rest of the day, returning to their burrows to sleep during the night.[6]
In areas frequented by people, hoary marmots are not shy. Rather than running away at first sight, they will often go about their business[clarification needed] while being watched.[citation needed]
Mating occurs after hibernation, and two to four young are born in the spring. Males establish "harems", but may also visit females in other territories.
Reproduction
Hoary marmots breed shortly after,[13] or even before,[14] their emergence from hibernation burrows in May. Courtship consists of sniffing the genital region, followed by mounting, although mounting has also been observed between females. Females typically raise litters only in alternate years, although both greater and lesser frequencies have been reported on occasion.[6][14]
Gestation lasts 25 to 30 days, so the litter of two to five young is born between late May and mid-June.[13] The young emerge from their birth den at three to four weeks of age, by which time they have a full coat of fur and are already beginning to be weaned.[15] The young are initially cautious, but begin to exhibit the full range of nonreproductive adult behavior within about four weeks of emerging from the burrow. Subadults initially remain with their birth colony, but typically leave at two years of age, becoming fully sexually mature the following year.[6]
