Rudd There were 499 rabid animals diagnosed at the Wadsworth Center laboratory in 2010, representing 7.5% of all animals tested. This total includes 250 raccoons, which was 26.1% of all raccoons examined (positivity rate), 85 skunks (43.8%); 68 bats (2.5%); 43 cats (3.2%); 31 gray fox (34.0%); 6 bovine (8.5%); 5 woodchucks (6.5%); 3 red fox (4.6%); 2 horses (5.0%); 2 coyotes (22.2%): 1 deer (2.5%) and 1 sheep (7.7%). Of concern in 2010 was the increased number of rabid cats found in the State. Raccoon rabies entered into New York State in 1990. As a result we have seen an increase in the spillover of raccoon rabies variant into cats and other domestic animals. Of the 38,022 cats tested for rabies at the Wadsworth rabies lab since 1990 there has been 556 cats found to be rabid. This is a 1.5% positivity rate over this 21 year period. In 2010 the positivity rate for cats was 3.2%. All of the 2010 rabid cats were infected with the raccoon rabies variant. Of the 43 rabid cats diagnosed in 2010; 22 were listed as wild or feral and 6 were identified as owner unknown; 14 were juvenile and 29 were adult; 25 were identified as having bitten a human and none of the rabid cats were identified as having a current rabies vaccination. The Wadsworth Center’s rabies laboratory tested 6,642 animals in 2010. This number is 2,138 specimens below the average submissions for the previous 10 year period and 633 specimens fewer than submitted in 2009. Raccoon rabies was reported in 48 and bat rabies was reported in 31 New York counties in 2010. In 2009 raccoon and bat rabies was reported in 46 and 35 counties respectfully. The specimens tested included 4,455 wild animals (67.2% of total submissions) and 2,183 domestic animals (32.8%), with 51 species of animals represented. These included 2,866 bats (43.1% of all animals tested), 1,331 cats (20%), 954 raccoons (14.4%), 651 dogs (9.8%), 194 skunks (2.9%), 208 rodents and lagomorphs (3.1%), 157 fox (2.4%), 70 cattle (1.0%), 41 deer (0.6%), 40 horses (0.6%) and 35 other wild species (0.5%). In 67.9 % of all animals tested there was either a bite to a human or human contact with saliva or nervous tissue. Of all bats tested in 2010, 2.4% were found to be infected with rabies virus. There were 2,537 big brown bats examined and 61 of those were positive, resulting in a 2.4% positivity rate for that species. Rabies was detected in 3 of 274 little brown bats examined (1.1% positivity), 2 of 12 silver-haired bats (16.6%), 0 of 16 red bats (0 %), 2 of 5 Hoary bats (40%) and 0 of 16 bats unidentified to taxa. Of the 68 rabid bats tested in 2010, 39 (57.3%) had contacts with humans. However, of all of the 2866 bats tested in 2010, 1,726 had contact with humans and were found to be negative for rabies. This testing prevented unnecessary post exposure prophylaxis and conserved the costly and limited supply of rabies vaccine and immune globulin. Of concern over the past five years is the disease affecting bats known as White Nose Syndrome. This disease affects predominantly bats of the genus Myotis (little brown bats). Between 1999 – 2008, the rabies lab tested an average 952 little brown bats per year. In 2009 that number dropped to 483, and in 2010 the rabies lab tested 245 little brown bats. This drastic drop in Myotis submissions for rabies testing is evidence of the steep decline in the number of these bats found in New York State. During 2009 the rabies diagnostic laboratory at the New York City Department of Health and Mental Hygiene examined 551 specimens, including 339 raccoons, 87 cats, 51 dogs, 21 opossum, 38 bats, 11 skunks, 2 coyotes, 1 beaver, and 1 groundhog. Among these animals 145 (26.3%) were positive for rabies, including 138 raccoons, 3 bats, 1 coyote, 1 skunk, 1 opossum and 1 cat. An epizootic of rabies in raccoons, focused in Central Park, resulted in the large jump of positives in New York City for 2010. The Wadsworth Center rabies laboratory tested 1,052 human sera for rabies virus neutralizing antibody. These tests generally are performed to determine the need for booster vaccinations for individuals wishing to maintain current rabies pre-exposure vaccination status. The laboratory also examined 1,815 raccoon sera for rabies antibody in support of wildlife oral rabies vaccination programs (ORV). The laboratory performed 82 virus-variant typing assays using a panel of monoclonal antibodies directed against the rabies virus nucleocapsid protein, to aid in the study of rabies epizootiology in the State.

  • Cornell's Naturalist Outreach Presents: Rodents: Nutty Adaptations For
    Cornell’s Naturalist Outreach Presents: Rodents: Nutty Adaptations for Survival By: Ashley Eisenhauer What is a rodent? Rodents are a very diverse, interesting group of animals. They can be found on every continent except for Antarctica. The largest rodent is the Capybara (left picture) from South America, and the smallest—about the size of a quarter—is the pygmy jerboa (right picture), indigenous to Africa. The feature all rodents share are continuously growing, gnawing teeth. This is what causes them to constantly chew on things, because they need to grind their teeth to keep them the proper size and sharpen them. Their other features, such as their vision, hearing, fur, feet, tails, sociality, and survival methods during the winter vary from species to species. Exploring the diversity of rodents is an effective way of demonstrating adaptations in animals. The rodents I will be talking about with students are the eastern gray squirrel, northern flying squirrel, woodchuck/groundhog, eastern chipmunk, and chinchilla. All of these are indigenous to New York, except the chinchilla which is from the Andes Mountains in South America. I will be bringing my pet chinchillas to my presentations to show how certain aspects of chinchillas are different from the rodents that live here in New York because of the climate difference. Some of these differences include larger ears for heat dissipation, thick fur for cold nights, and large herd sociality. Local critters that are often mistaken as rodents are rabbits, which are actually Lagomorphs. This is a common misconception because they also have continuously growing teeth and are constantly chewing on something.

  • Groundhog Day 2020: for the First Time in History, Punxsutawney Phil Predicts Second Consecutive Early Spring
    FOR IMMEDIATE RELEASE February 2, 2020 Groundhog Day 2020: For the First Time in History, Punxsutawney Phil Predicts Second Consecutive Early Spring Punxsutawney, PA – This morning, Pennsylvania’s own world-famous groundhog Punxsutawney Phil once again predicted an early spring after he did not see his shadow, a prediction so rare that it has only happened 20 times in the 134-year history of Groundhog Day and never two years in a row. Residents of Punxsutawney and visitors from across the nation gathered to see Phil make his highly-anticipated weather prognostication, during Pennsylvania’s unique Groundhog Day celebration. “Groundhog Day is a beloved Pennsylvania tradition that has been embraced wholeheartedly by communities across the country,” said Gov. Tom Wolf. “We are honored Phil has called our commonwealth his home for more than 100 years and look forward to continuing to share his prediction with visitors, residents, and the millions watching from their homes.” The event now attracts up to 30,000 visitors to Punxsutawney, Jefferson County, located about 80 miles northeast of Pittsburgh. Phil has predicted six more weeks of winter weather 104 times while forecasting an early spring 20 times. The story of the holiday tradition declares that if the groundhog emerges early on the morning of February 2 and sees his shadow, we will have six more weeks of winter weather. Should he not see his shadow, we will have an early spring. The annual event began in 1886, when a spirited group of groundhog hunters dubbed themselves "The Punxsutawney Groundhog Club” and proclaimed Punxsutawney Phil to be the one and only weather prognosticating groundhog.

  • Wildlife Spotting Along the Thames
    WILDLIFE SPOTTING ALONG THE THAMES Wildlife along the Thames is plentiful, making it a great location for birding. Bald Eagles and Osprey are regularly seen nesting and feeding along the river. Many larger birds utilize the Thames for habitat and feeding, including Red Tailed Hawks, Red Shoulder Hawks, Kestrels, King Fishers, Turkey Vultures, Wild Turkeys, Canada Geese, Blue Herons, Mallard Ducks, Black and Wood Ducks. Several species of owl have also been recorded in, such as the Barred Owl, Barn Owl, Great Horned Owl and even the Snowy Owl. Large migratory birds such as Cormorants, Tundra Swans, Great Egret, Common Merganser and Common Loon move through the watershed during spring and fall. The Thames watershed also contains one of Canada’s most diverse fish communities. Over 90 fish species have been recorded (more than half of Ontario’s fish species). Sport fishing is popular throughout the watershed, with popular species being: Rock Bass, Smallmouth Bass, Largemouth Bass, Walleye, Yellow Perch, White Perch, Crappie, Sunfish, Northern Pike, Grass Pickerel, Muskellunge, Longnose Gar, Salmon, Brown Trout, Brook Trout, Rainbow Trout, Channel Catfish, Barbot and Redhorse Sucker. Many mammals utilize the Thames River and the surrounding environment. White-tailed Deer, Muskrat, Beaver, Rabbit, Weasel, Groundhog, Chipmunk, Possum, Grey Squirrel, Flying Squirrel, Little Brown Bats, Raccoon, Coyote, Red Fox and - although very rare - Cougar and Black Bear have been recorded. Reptiles and amphibians in the watershed include Newts and Sinks, Garter Snake, Ribbon Snake, Foxsnake, Rat Snake, Spotted Turtle, Map Turtle, Painted Turtle, Snapping Turtle and Spiny Softshell Turtle. Some of the wildlife species found along the Thames are endangered making it vital to respect and not disrupt their sensitive habitat areas.

The National Audubon Society, in collaboration with the U.S. Fish and Wildlife Service, sponsor Christmas Bird Counts annually throughout the country and beyond in the Americas. Each count consists of a tally of all birds seen within a fifteen-mile diameter circle on one day that falls within a 15-day period at the end of December and the beginning of January. Audubon Christmas Counts have been taking place for 119 years and provide valuable information on the range expansion or narrowing of wintering bird populations. The center for the Oak Orchard count is the point at which the Genesee-Orleans County line crosses Route 63. The 15-mile diameter circle includes the Iroquois National Wildlife Refuge, Oak Orchard and Tonawanda State Wildlife Management Areas, the Tonawanda Native American Reservation, the Townships of Alabama and Shelby, the villages of Indian Falls, Medina and Wolcottsville and portions of Middleport and Oakfield. Count hours were warm and mild, with a low of 39F and high of 57F. both above the average daily temperature for the date of 34F. Both morning and afternoon were essentially precipitation free. Our observers were afield in fourteen parties from 6:30 AM until 5:50 PM, and in 322.5 total hours covered 35 miles on foot and 504 miles by car! One observer counted birds at home feeders.

History of Groundhog Day Groundhog Day originates from an ancient celebration of the midway point between the winter solstice and the spring equinox—the day right in the middle of astronomical winter. According to superstition, sunny skies that day signify a stormy and cold second half of winter while cloudy skies indicate the arrival of warm weather. The trail of Phil’s history leads back to Clymer H. Freas, city editor of the Punxsutawney Spirit newspaper. Inspired by a group of local groundhog hunters—whom he would dub the Punxsutawney Groundhog Club— Freas declared Phil as America’s ocial forecasting groundhog in 1887. As he continued to embellish the groundhog's story year after year, other newspapers picked it up, and soon everyone looked to Punxsutawney Phil for the prediction of when spring would return to the country.

  • Groundhog Day Is Celebrated on February 2Nd and It Is the Day When People Look to the Groundhog to Predict the Weather for the Next Six Weeks
    GROUDHOG DAY READ ABOUT THIS TRAD ITION A N D TELL YOUR PARTNER IS A S M U C H DETAIL AS POSSIBLE Source: https://www.ducksters.com/ Useful Vocabulary: burrow/ˈbʌr.əʊ/ hole or tunnel dug by a small animal, especially a rabbit, as a dwelling, especially to live in www.cristinacabal.com Groundhog Day is celebrated on February 2nd and it is the day when people look to the groundhog to predict the weather for the next six weeks. Folklore says that if the sun is shining when the ground hog comes out of his burrow, then the groundhog will go back into its burrow and we will have winter for six more weeks. However, if it is cloudy, then spring will come early that year. This is a tradition in the United States. There are a number of celebrations throughout the United States. The largest celebration takes place in Punxsutawney, Pennsylvania where the famous groundhog Punxsutawney Phil has predicted the weather each year since 1886. Large crowds of well over 10,000 people gather here to see Phil come out of his burrow at around 7:30am. The origins of Groundhog Day can be traced to German settlers in Pennsylvania. These settlers celebrated February 2nd as Candlemas Day. On this day if the sun came out then there would be six more weeks of wintry weather. At some point people began to look to the groundhog to make this prediction. The earliest reference to the groundhog is in an 1841 journal entry. In 1886 the Punxsutawney newspaper declared February 2nd as Groundhog Day and named the local groundhog as Punxsutawney Phil.
