Sandhill Cranes in WildHave you walked outside recently and heard a loud rattling bugle coming from the sky, and thought to yourself “what in the world is making that noise?” More than likely, you were hearing the calls of sandhill cranes. Often times you can hear the calls of sandhill cranes long before you see them, and sometimes you may never even see them. Sandhill cranes can fly at altitudes exceeding 1-mile high and their calls can be heard from more than 2 miles away.

Sandhill crane sightings are a common occurrence in Indiana from October through early-December and from February through March as the cranes migrate between their breeding grounds in Michigan, Minnesota, Ontario, and Wisconsin and their wintering grounds in Florida, Georgia, and Tennessee.

When and where to view sandhill cranes in Indiana

While sandhill cranes can be viewed throughout the state, Jasper-Pulaski Fish and Wildlife Area in Medaryville, IN is one of the top spots in the eastern U.S. to view sandhill cranes. Jasper-Pulaski lies in the heart of the sandhill’s migratory path, and the birds congregate here in the thousands to tens-of-thousand during the fall and spring migration. Jasper-Pulaski serves as an important staging area for eastern sandhill cranes during migration, and the cranes stop here to rest and replenish their fat reserves to complete the migration.

Fall is the best time of year to view sandhill cranes at Jasper-Pulaski, and more specifically crane numbers are the greatest from mid-November to early-December. The Indiana DNR has a website that provides information about the sandhill crane migration at Jasper-Pulaski. Managers at Jasper-Pulaski even track the number of cranes using the area weekly, throughout the fall migration, and post an estimated count to the website. On Nov. 7th, 4,630 sandhill cranes were counted at Jasper-Pulaski. You can view cranes from the observation deck located just to the west of the Jasper-Pulaski main office.

Other hot spots to view sandhill cranes during migration include Pigeon River Fish and Wildlife Area in northeast Indiana, Goose Pond Fish and Wildlife Area in southwest Indiana, and Muscatatuck National Wildlife Refuge in southeast Indiana.

GPS collars on sandhill cranes highlight importance of Jasper-Pulaski

Just how important is Jasper-Pulaski to sandhill cranes? Researchers with The U.S. Fish and Wildlife Service and the University of Minnesota attached Global Positioning System (GPS) collars to sandhill cranes to track their fall and spring migratory routes. A majority of the sandhill cranes, regardless of where spent the summer or winter, stopped at Jasper-Pulaski during the migration. Sandhill cranes spent 34% of the fall and spring migratory period at Jasper-Pulaski, which is almost twice as much time as any other single place on their migratory route. The map below shows the migratory paths taken by GPS-collared sandhill cranes during the fall (gold lines) and spring (blue lines).

Indiana DNR IndentityThe Indiana DNR bovine tuberculosis surveillance team earned the Excellence in Conservation Award from the Midwest Fish and Wildlife Agency for their bovine tuberculosis surveillance and monitoring efforts in 2016.

In 2016, a wild white-tailed deer tested positive for bovine tuberculosis in Franklin County, Indiana. Bovine tuberculosis is a bacterial disease most often found in cattle and captive cervids, but can be transmitted to wild white-tailed deer and other wild mammals. The DNR tested more than 2,000 hunter-harvested deer in 2016 and did not find another bovine tuberculosis positive deer. For more information on bovine tuberculosis in wild white-tailed deer check out our Purdue Extension-FNR webpage: Bovine Tb in wild white-tailed deer: background and frequently asked questions.

While researchers say it is difficult to determine whether unusual weather patterns this winter and spring will lead to larger mosquito and tick populations in the Upper Midwest this summer, one thing is certain – anyone planning to spend time outdoors should take steps to avoid the potentially dangerous pests.

“Every year we face the same risks and every year it is wise to take precautions,” said Catherine Hill, Purdue University medical entomologist. “If you’re going to be outside anytime from early spring to late summer and early fall, you need to be thinking about prevention and protection.”

Both mosquitos and ticks can carry a number of pathogens that could pose a serious threat to people and animals. Mosquitos can transmit several viruses that can cause severe encephalitis (inflammation of the brain and spinal cord), including Zika and West Nile virus, among others. Ticks are known carriers of Lyme disease, which infects about 300,000 people each year, as well as less common but equally dangerous conditions such as anaplasmosis, babesiosis, Powassan and Rocky Mountain spotted fever.

To avoid mosquito bites, the best advice is to stay indoors during peak biting times, which is typically dusk to dawn for the mosquitoes that transmit West Nile virus and during the day for mosquitoes that transmit Zika.

“If you have to be outside during those times, it is best to wear clothing that can help prevent bites,” Hill said. Appropriate wardrobe choices include long-sleeve shirts and long pants tucked into socks. It is also advisable to use an effective repellant, such as products containing a minimum of 20 to 30 percent – of diethyltoluamide, commonly known as DEET. The Centers for Disease Control also recommends products containing picardin, lemon of eucalyptus and IR3535. More information is available on the CDC website at https://wwwnc.cdc.gov/travel/yellowbook/2016/the-pre-travel-consultation/protection-against-mosquitoes-ticks-other-arthropods.

Mosquitoes breed in standing water and their larvae and pupae need water to develop. Homeowners can help reduce mosquito populations in their back yard by dumping standing water out of buckets and wading pools, keeping lawns mowed and removing piles of brush or yard waste, Hill said.

Ticks can thrive in back yards as well, particularly those adjacent heavily wooded areas, in tall grass and brush and under leaf piles.

Hill said the warmer winter and wet spring could have created ideal conditions for ticks in some areas although conditions vary significantly from region to region.

“We’ve already been getting plenty of ticks,” Hill said. “They’re certainly active.”

The best defense against ticks is to wear light colored clothing with long sleeves and pants and to use a U.S. Environmental Protection Agency-approved repellant. It is also a good idea to check your body and clothing for ticks immediately after coming back indoors.

“If you can remove a tick within 24 hours, you have a very good chance of catching them before they transmit,” Hill said.

Ticks feed on blood and tend to attach themselves to tender areas of the skin, including around the hairline and in the armpit and groin.

The end of the school year represents not only the beginning of summer but also the start of field season. Time spent out in the field can be fun, informative, and an opportunity to gather important data. Field data can also be difficult to gather as outdoor conditions are often unpredictable. Anyone expecting to do work out in the field must be prepared for anything. In addition to the likelihood of heat stress and the threat of diseases carried by insect assailants (i.e. ticks, mosquitoes), those in the field must prepare for events that come naturally with doing research outside of a controlled environment.

Packing an emergency bag before venturing into the field is one way to ensure that negative ramifications of any accidents are kept to a minimum or eliminated completely. Standard emergency supplies should accompany field researchers on every trip. The nature of the outing should also be considered since additional, more specialized, equipment may be needed in some areas. Typical emergency equipment needed for each foray into the wild includes:

  • Charged cell phone with an extra battery and a charger (stored in plastic bag with some petty cash)
  • Fully stocked first aid kit (large size with an array of bandages and wound wrapping materials) with specialized field supplies (fish hook removers, seasickness tablets, flare gun, mosquito net, etc.) and general forest supplies (sunscreen, poison ivy/oak/sumac cream, insect repellent)
  • Vehicle emergency kit (with vehicle operator’s manual and emergency blankets)
  • Non-perishable, easy to open food stuffs (i.e. peanut butter, beef jerky, granola bars)
  • Water (minimum of 1 gal / person / day of the trip plus an additional 3 days) and water purification tablets or filter devices
  • Plastic Ziploc bags for personal hygiene products (toilet paper, sanitizing wipes, feminine products), extra clothes including a brimmed hat, and electronic devices
  • Local guidebook and ability to identify hazardous plant and native wildlife species in the traversed field region
  • Flashlight (with extra batteries)
  • Two-way radio (if necessary to work alone in an isolated or dangerous area and check in regularly) and handheld weather station
  • Personal protective equipment (safety glasses/goggles, gloves, hard hat, sturdy boots, etc.)
  • Identification (photocopy of driver’s license, medical prescriptions and coverage information, and emergency contact information) for everyone in the field
  • Maps, compass, and GPS unit

Following this list is the first start to a safe and successful field season! Best of luck!

Tree trunk cracked. Trees are lost or seriously damaged every year from high winds, heavy rainfall and other storm-related weather. In addition to physical damage or loss, risk and liability can become a concern to people and the surrounding property. Seasonal storms can cause extensive damage depending on timing and intensity. Stem failure, root failure and cracked branches are just a few of the vital signs that need to be addressed to aid in weather damage.

Once the tree is damaged, deciding on what to do is an important process. Urban Forestry Specialist Lindsey Purcell explains common tree injuries and how to identify them, how to conduct a risk assessment when trees are damaged and steps to take after the storms are over in his publication “Trees and Storms“.

Lindsey Purcell is also featured in WLFI’s video “What to Do With Your Damaged Trees,” where he shares important information on identifying weak areas in trees and Kevin McCombs, Public Information Officer for Wabash Township Volunteer Fire Department, adds additional insight.WLFI - What to do with your damaged trees

pesticidePesticides are a great way for farmers and homeowners to protect plants against insects and disease. However, sometimes pesticide ends up where it isn’t supposed to – on neighboring properties like homes, schools, and parks. This is called pesticide drift, and it can be very dangerous to your health and damaging to property. You have the legal right to be free from pesticide drift, and it is important to be able to recognize it and understand what to do next if you are experiencing it. Purdue Extension-Pesticide Program has a new publication titled “Options for Dealing with a Pesticide Drift Incident” sharing resources to help simplify that process, explore what exactly pesticide drift is, what causes it, and what steps you can take to resolve it. The publication is available as a free download in The Education Store, so those interested can take a look and be sure to stay safe and informed about pesticide drift.

As the weather begins to warm up later this year, the sight of Canada geese returning is pleasant to some as a reminder of spring approaching. It can also be downright irritating to others who experience property damage and other conflicts as the geese concentrate on their property. There are several strategies for dealing with geese listed in further detail at the Indiana Department of Natural Resources (IDNR) website, ranging from mild to severe.

The first thing that is important to know regarding geese is that it is simply not a good idea to feed them. While this act is positive in intention, it is a bad thing for both people and geese. Feeding geese gives them an artificially abundant source of food, which can cause them to delay or skip their migration and instead congregate in areas where they will conflict with people. Furthermore, being fed can cause geese to lose their fear of people, giving them the confidence to stroll across roadways and runways. Finally, large amounts of geese competing over bread and other food of limited nutritional value greatly increases their chances of developing and spreading avian diseases. The U.S. Fish & Wildlife Service‘s free publication “Caution: Feeding Waterfowl May Be Harmful!” further explains the need to stop feeding geese.

INDNR offers a significant amount of other advice on other methods of handling goose problems. Habitat modification such as adding vegetative barriers or suspended grid systems can be a good long term solution by making your land less attractive to geese. If geese have already begun to settle in, nonlethal harassment techniques like air horns and sprayers can be used twice a day to scare geese away from your property. Nests can be legally removed as long as there are no eggs present. If the situation calls for more severe actions, a permit can be acquired to destroy nests with eggs, or another permit can be issued by a District Wildlife Biologist to capture and relocate the animals. In cases of excessive property damage, a District Wildlife Biologist can also issue an agricultural depredation permit to shoot geese outside of the normal hunting season.

There are many methods of handling nuisance Canada geese this spring, and not one solution for every problem. If there is a goose problem in your area, please view INDNR’s Nuisance Canada Goose Management page to learn more about what you can do and how to acquire permits if needed.

You may have likely heard of the Zika virus at this point – a new infection on the rise that is drawing many parallels to the West Nile virus that caused 286 deaths in the United States in 2012. Like the West Nile, Zika was first discovered over sixty years ago and wasn’t considered to be a large concern until it reemerged unexpectedly years later. Both viruses are carried by mosquitos, and 80% of people infected display no symptoms and are at risk of unwittingly further spreading the infection. And most importantly, both viruses have no current treatment or vaccination and can be deadly.

When discussing the Zika virus, it is important to know that currently there have been no cases of infection in the continental U.S. While this means there is no need to immediately panic, transmission of diseases are often unpredictable as human population and global travel increase. Zika appeared in Brazil last May and has quickly spread to over 20 countries across Central and South America, causing the World Health Organization to declare the virus an international public health emergency, predicting that Zika could infect as many as 4 million people by the end of this year. With that ominous prediction looming over us, a good precaution to take is knowing how the mosquitos potentially carrying the virus can be controlled and avoided.

Simply avoiding mosquitos is an effective first step. Staying indoors during the daytime when mosquitos feed can help lessen exposure to mosquitos, as well as wearing long sleeves, pants, and U.S. Environmental Protection Agency-approved mosquito repellant when going outdoors.

Another preventative measure you can take is eliminating potential mosquito breeding sites from your area. Mosquitos breed in containers of standing water, and getting rid of them can reduce mosquito population in your area. Dog bowls, birdbaths, potted plants, and similar objects are all potential breeding grounds, and removing them means less places for mosquito eggs to hatch.

Again, the Zika virus isn’t currently an immediate concern for people in the United States, but this information is crucial to know as scientists learn more about how this virus is spread. At any rate, they’re also give good tips for avoiding annoying mosquito bites! To learn more, please check out the Purdue University Agriculture News article “Controlling and avoiding mosquitos helps minimize risk of Zika.”
