Habitats and animal movement: edges, water, dawn and dusk

Every animal needs food, water, cover and rest. All four rarely lie in a single place. So animals move back and forth between them, and because they prefer convenient and safe routes, they use the same ones again and again. That is how game trails form.

At the boundary between two habitats, such as forest and meadow, hedge and field, or shore and land, cover and food lie close together. Such edge zones are therefore often used more intensively than the interior of large, uniform areas. In ecology this is called the edge effect: diversity and activity are often higher at transitions between habitats.

Landforms also steer movement. Passes, shore strips, stream courses, narrow passages between rocks or gaps in fences funnel the routes of many animals. These are called corridors. You often find especially many tracks there.

Many mammals are crepuscular or nocturnal. “Crepuscular” means they are mainly active in the morning and evening when it is half light. That is when they move between their resting places and their feeding places. At midday many animals lie in cover. For observation, the early morning and late evening hours are therefore usually the most rewarding.

Water attracts animals from the whole surroundings, especially in dry periods. In dry regions water sources are real focal points where many animals gather at certain times.

The season changes behaviour too. During breeding, birthing and mating seasons animals are often more sensitive and sometimes more defensive. Keep extra distance at those times and respect protection periods and closed areas. In winter animals need their energy, and every disturbance costs them strength.

Do not set up camp directly at water sources, on game trails or at feeding sites. The likelihood of wildlife encounters is higher there, and you block animals' access. Especially in dry areas, keep your distance from the only water source around so the animals can keep drinking.

This knowledge helps when driving too. At dawn and dusk wild animals cross roads more often, especially along forest edges and where signs warn of wildlife crossings. Drive more slowly there and be ready to brake. Animals often do not appear alone – where one runs across the road, others may follow.

And: this knowledge is meant for watching animals and avoiding conflicts, not for seeking them out in their quiet zones. Local protection periods and path rules always take precedence.

You can plan a lot at home with a topographic map. Look for forest edges, hedgerows, streams, lakes, saddles – low points between two summits – and narrow passages. Animal routes often cross there.

Then ask yourself: where is cover, such as a thicket or rocks? Where is food, such as a meadow, a field or berry bushes? Where is water? The imagined connecting lines between these places are likely trails. In the field you can check whether you actually find tracks there.

From this, choose an observation spot at a distance from an edge zone, ideally with the wind in your face. For a campsite do the opposite: away from water sources and trails. This works in cities too: railway embankments, riverbanks, parks and gardens are corridors, and nocturnal garden visitors often follow hedges and fences.

Everything in this entry is about probabilities, not certainties. Animals do not follow rules, and behaviour varies greatly between regions, species and seasons. Exact predictions are therefore not possible.

Trackers have always used the edge effect to find promising places. For hikers and campers, the same insight is a simple safety rule: where animals move regularly is not a good place to camp. The Leave No Trace principles likewise call for choosing campsites so that wildlife is not disturbed.
