How to spot wildlife on a day hike: Choose when, where you’ll walk

When spotting wildlife, such as this desert

keep your distance.

Patience in search required
but often proves rewarding


The following originally appeared as an article, by Hikes with Tykes author Rob Bignell, at Seattle Backpackers Magazine.

Spotting wildlife certainly marks one of the highlights of any day hike, especially when with children. The graceful leap of a deer into the thicket, the curious habits of a rabbit or squirrel, the noble sweep of an eagle through the skies, all serve to astonish, entertain and teach.

Animals prefer to remain hidden (except for those pesky mosquitos, of course), so seeing them can be difficult. You’ll often have to be patient, even on trails in which wildlife sightings are touted in guidebooks and brochures. Still, there are strategies any hiker can use to improve the odds of seeing wild animals.

First, some trails provide better opportunities than others to spot wildlife. Paths alongside lakes and rivers are particularly good as many animals will come to the waterbody to drink. Trails alongside or through meadows also are excellent, for they offer wide open spaces to spot animals grazing in the distance or flying overhead.

The time of day and year you opt to hit the trail also can increase your chances of seeing wildlife. You can best spot animals if you go hiking during:
g Feeding times – Wildlife typically are more active at dawn and dusk. Knowing the types of plants some animals prefer will help you know when you’re in an area that animals feed.
g Migrations – You’ll be able to sight large numbers and a greater variety of birds passing through an area during spring and autumn. Wetlands and large bodies of water usually draw the most migrating birds.
g Greater Visibility – Green leaves in spring and summer tend to hide animals, but as leaves fall off trees and bushes during autumn, your field of visibility will increase.
g Newborn Presentations – During spring and early summer, mothers often take their slow-moving offspring out to explore the world. Watch for them at the edges of woods.
g Changes in Barometric Pressure – That means before and after a storm. Before a storm, many animals seek better shelter to outlast a shower; watch the skies for raptors that also know this and so go on the hunt at that time. Of course, you also must be careful to avoid lightning strikes and flashfloods.

Should you spot wildlife on a hike, always remember to keep your distance. If closing on them doesn’t scare them off, the animal probably will stand its ground and possibly even attack. In addition, it’s never cute to have a child get close to a wild animal for a picture when the creature bites or mauls them.

Don’t be tempted to feed wild animals either. Besides inviting an aggressive attack on you, it teaches animals that humans are a source of food, meaning some are less likely to hunt or graze on their own but instead become a nuisance and even a threat to people. Such is the case with many national parks bears, who’ve learned to raid dumpsters and tents and even break into vehicles for food.

Also, don’t pick up small wild animals, as their natural inclination is to bite and claw when held. Even if docile, it may bite when you get close. If it is sick and a bite occurs, you could contract a disease.

If there are reports in an area of a dangerous animal, especially one that has attacked people, don’t hike there in hopes of spotting it. While such attacks are rare, there’s no need to invite trouble.

Short of seeing wildlife, the next best thing is to catch signs of them. When passing patches of sand or dirt, watch for animal prints. Other signs of animals include scat, flattened plants where an animal may have rested, feathers, fur on fence posts, burrow holes, and scrapings on tree bark.

How to find drinkable water if lost in wilds

Avoid directly drinking water from a stream, pond or lake.

Use spring water; always boil, filter


If you’re lost or forced to stay a night in the wilds, avoid using local sources of drinking water. Still, sometimes you must take a calculated gamble or dehydration will set in.

The first challenge is to find a source of local water. Spring water is the best discovery, as it runs the lowest risk of being contaminated. Your next best bet is finding flowing water from a stream that is high in the mountains or hills, as it’s more likely than not to be clean as it is close to its source, which is melting snow. Flowing water at the bottom of a mountain or hill is your next best choice. Still water on low-lying land is your worst.

Finding water in a desert
If you’re not lost but simply stuck in the wilds for a night due to an injury, check your topo map. Well-known springs often are marked on them.

In a desert, finding water at all can be nearly impossible, but it is out there if you know where to look. On seasonal waterways, the thicker and greener the vegetation the more likely the chance that you’ll find standing water nearby. A grove of cottonwoods and willows almost guarantees that ground water is nearby. If there isn’t any, dig in the cool sand under a willow, and you may find water only a few inches down. Puddles also may exist under large overhangs and in shaded rock crevices, particularly if they are on a hill’s north side.

To collect the water, simply use one of your canteens or water bottles. Don’t dump out good water that you’ve carried in, however, but combine it with water in another partially filled canteen. If the water source is too shallow for a canteen, spread your handkerchief across the water surface. When the handkerchief has absorbed the water, wring it out into your canteen.

Once you’ve collected water, you need to “clean” it before imbibing. There are three options: use water purification tablets, boil it, or use a water filter.

Boil at least 5 minutes
A variety of water purification tablets are available for sale, so follow the instructions on each packet for the best results. Generally, though, tablets have to sit in the water for at least 30 minutes – and if the water is cold, the tablets may need to mix in it overnight. Tablets always will leave a little aftertaste, ranging from iodine-like to a tart flavoring. Be aware that if you or your child has thyroid problems, water purification tablets may contain iodine and probably should not be used.

If boiling, do so for at least 5 minutes. This will kill Giardia and all but the hardiest microscopic bugs. Boiling won’t remove chemical contaminates, however. In addition, if water is cloudy and you can’t see any life such as fish or amphibians in it, boiling probably won’t make it safe. When boiling water, do not do it in your plastic canteen or water bottle. The plastic likely will melt, or you won’t be able to touch it when hot. Given this, you may want to add “cooking pot” to the list of items for your backpack, but I’d only do so if you’re planning a long hike into the backcountry.

A number of water filters exist, all using different filtration systems and coming in different sizes. Whichever one you choose, make sure the filter pores are smaller than 0.2 microns. Anything larger will allow nasty bacteria to get through and remain in the water.

What are the advantages of each filter over the other? One that lacks iodine won’t remove viruses, so you’ll need to use water purification tablets or iodine anyway. A carbon or charcoal filter will remove chemicals that purification tablets and boiling won’t get rid of. Reverse osmosis filters are best of all, removing almost everything bad and even desalinating sea water. Unfortunately, they’re bulky and expensive, and you probably aren’t going to carry one on a day hike let alone a camping trip.
