The spring like weather this past month has caused some changes to the wildlife populations in our backyards. For instance, I have noticed robins in my backyard looking for food. Normally a sign of spring, these early robins are may be in for a long late winter as temperatures drop below freezing keeping the worm and insect food sources scarce. You may have noticed robins in your fruit bearing trees and shrubs, gleaning the last remaining fruits from the plants. Fruits are a secondary food source for robins. If you are a bird feeding enthusiast, you may want to add raisins to your feeding platform for the robins until warm temperatures activate insect populations.

I have also received some earlier than normal telephone calls concerning bats in homes. The big brown bat often hibernates in attic and wall spaces in central Illinois and warm outside temperatures may cause some of these animals to become active. These bat encounters usually involve one or two bats that seek the warmer house temperature and enter your living space. If you can close off the room they are in and open a window the bat will often fly outside on their own. If you decide to speed up the process with a butterfly net, be careful so as not to be bitten.

If you do encounter a bat intruder this late winter, you will want to try to locate the outside entrance hole in your house when spring finally does arrive. The task of bat exclusion is often best left to a professional. However, the University of Illinois Champaign Extension office can provide a detailed fact sheet on the process if you want to consider dealing with the problem yourself.

The warm weather may likely increase the activity of other animals in your backyard, so you may want to begin monitoring for other common spring wildlife nuisance conflicts. I have noticed increased Canada geese and duck movement lately too. The resident urban populations of Canada geese may begin searching for suitable nesting areas earlier than normal. The day length is a bigger factor in signally nesting in geese and other birds, but if you are planning on installing fencing or other barriers around your small pond to limit Canada goose nesting it may pay off to be on the cautious side this year. Fencing or string barriers at the water's edge of a pond are most effective when installed prior to nest territory selection.

Another common spring nuisance call I receive concerns woodpecker drumming. Drumming is a spring territorial activity that is done by pecking on a hollow tree. Unfortunately in urban areas these locations may be limited, so the birds use what is available, your chimney's flashing, eaves or the corner of your home's siding. Again, you may want to monitor for this activity earlier than normal. If you want to disrupt or move the woodpecker to another area, you must intervene as soon as the activity begins. Woodpecker are protected by state and federal laws, so they cannot be killed, the objective is to scare them away. Strips of mylar can be hung from eaves to scare the birds or the drumming area can be temporarily covered, but this can move the bird to another part of your home.

It's difficult to predict what will happen with temperatures the rest of the days of winter, and the affect on wildlife activity. The best approach to reducing wildlife nuisance conflicts is anticipation and preparation, so watch the wildlife in your neighborhood. You may even find it entertaining.
