What Are the Sounds Made by Birds, and How Do They Warn Us? Action Steps To Take

Since you know what your feathered friends are communicating, here’s how you can respond to their warnings in a quick and effective way. Responding quickly can change a minor garden issue to an awful problem.

Nematodes can be applied to your lawn when the soil temperature is between 60-85°F. They need moisture to survive and spread so water them before applying them. These microscopic soldiers will locate Japanese beetle larvae without harming your grass or beneficial insects. To determine the best time of day to apply them to your lawn, either do so in the early morning or evening.

When woodpeckers tell you there's trouble with a tree, look closely at the bark for small holes or piles of sawdust. If you notice borer beetles in their early stages, you may be able to save the tree with systemics applied to the soil in the root zone. On the other hand, if you see significant damage or several exit holes, it is best to consult a qualified arborist right away.

When crows indicate dry soil conditions, it is important to conduct deep watering. You should install soaker hoses or drip irrigation systems that will allow water to be delivered slowly and deeply to the soil at a depth of 8 to 12 inches. Watering more frequently at shallower depths will encourage roots to stay near the surface, which can actually worsen the problem.

Developing a garden that attracts birds and benefit you as well

You can even attract more birds to your garden! More birds in your garden mean more natural pest control and less problems in your garden.

Nest and feeding sites can be provided by planting native shrubs and trees. Birds can be attracted all year by berry-producing plants like elderberry, serviceberry, and native viburnums. Allow some areas of your garden to be a little wild. Places for birds to forage and hide are created by brush piles and unmowed areas.

Offering various clean water sources at different heights will attract various species. A ground level birdbath will attract different birds than a hanging water feature. Change the water every few days, to prevent mosquito breeding, and keep your feathered helpers healthy.

Bird Behavior Myths That Could Cost You

Not all bird behavior indicates a problem with the garden and misunderstanding signs can cause undue alarm or result in opportunities being missed. Most misunderstandings that confuse gardeners here are the common ones.

It's not unusual for birds to gather in large flocks. Usually, it's just migration or they found a good food source. If the the flocks are composed of the same species, and they are there in unusually high numbers for weeks, then it might be worth looking into.

Birds' aggressive behavior is not just about the pests. During the nesting period, a lot of birds become very aggressive and will chase off other birds and even people who get too close to their nests. This is normal and actually shows that there is a healthy population of birds.

Seeing birds in your garden may not be a bad thing! Birds are normally attracted to healthy gardens with a variety of fresh fruits and vegetables that the birds can eat. The challenge is knowing the difference between normal feeding behavior of birds and the behavior of birds that suggests there is a pest problem.

Birds and the Health of Your Garden: Most Commonly Asked Questions

How fast do I need to react to signs of warning from birds? Most warnings from birds indicate problems that require attention within 1-2 weeks. But problems such as tree borers or venomous spiders require immediate action- 24-48 hours.

Should I only look at birds to monitor my garden health? While birds are great early warning systems, they should always be used with regular inspections of your garden. Birds are great at detecting problems that you might miss, like underground pests or pest eggs.

Why are there no birds in my garden? Not seeing birds may mean there is pesticide use nearby, no food, water, and too much activity of people. Consider offering water, native plants, and chemical reduction as a starting point.

Are bird warning signs different in different countries? Yes they are. Local species of birds and garden pests are found in different places. Learn to identify the most common garden birds in your area and the pests they usually prey on. You can get region-specific information from your local extension office.

How do I distinguish warning signs from regular bird behavior? A sudden behavior change is a good indicator. An absence of normally visiting species, large numbers of new species, and frantic or aggressive behavior of usually calm birds merit further investigation.

Should I feed birds if I want them to hunt pests in my garden? Yes! Supplemental feeding will cause birds to stay in your area and hunt more. Well-fed birds are more successful at catching pests and are more likely to raise successful broods that will continue the pest control.
