Birds are harbingers of changing seasons. When juncos show up, we know winter is close behind. When they disappear, spring is close at hand. It’s become a contest with my friends to see who can see the first hummingbird or oriole in the spring.
If you love the songs of birds and enjoy watching them, there are many ways you can attract them to your yard and garden. Birds need a source of water, not only for drinking, but also for bathing. Feathers must be kept clean to provide good insulation and facilitate flying. Shelter from summer heat and harsh winter wind and snow must be available.

This involves having a variety of trees and shrubs in your yard that are dense. Evergreen shrubs and trees are good sources of both shelter and food for the birds as well as nesting sites. Trees and shrubs also provide escape and shelter from larger birds of prey.
It is interesting to watch avian predators match wits and flying skills with smaller birds in the cycle of life. Plants that produce a lot of seeds like coneflowers, trees that have fruits, and small fruit like strawberries all attract birds. Trees that hold their fruit over the winter, such as crabapples, are especially welcomed by birds. Of course, you must decide whether the presence of a large variety of birds with their song, beauty and antics is worth the price of sharing your garden and its produce with them.
The public is invited to a special presentation by Helen Hollis from 6 to 8 p.m. March 23. She will be speaking on the declining chimney swift birds and how we can help build their population. This special presentation will be held in the large conference room at the Sandusky County extension building at 2000 Countryside Drive. For more information call Sue at the extension office at 419-334-6340 and leave a message.

Occurring nearly everywhere worldwide, the only place owls don’t exist is Antarctica. Represented by two avian families, some 135 species of owls can be found hiding, hunting and hooting throughout the world, including 12 species here in Minnesota alone.
The Land of 10,000 Lakes is inhabited by great horned, long-eared, short-eared, barred, burrowing, great gray, northern hawk, eastern screech, northern saw-whet, boreal, snowy and barn owls.
Some species occur here intermittently, like great gray, northern hawk and snowy owls, while others, like barn and burrowing owls, have a limited range in Minnesota.
Most owls are nocturnal and they’re all birds of prey. Some, such as short-eared owls, are diurnal and twilight hunters. But for most species of owls, twilight and nighttime is the time of activity.
Replacing eagles, hawks and falcons as top avian predators of the daylight hours, owls are true masters of darkness and come equipped with adaptations unmatched in predatory birds.
For starters, owls' vision is extraordinarily acute. Like us, owls have binocular vision. All this means is that an object can be seen with both eyes at the same time. But that’s where the similarity essentially stops. Owl eyes are very large. Both the outer portions of the eye and the pupil are large too.
The iris (a membrane between the cornea and lens) controls the pupil’s size.
On particularly dark nights an owl’s pupils are at their largest, which in turn allows the maximum amount of light to enter into the eye. Special light-sensitive cells are especially abundant, more so than color-sensitive cells that contribute to an owl's amazing ability to see in the dark.
Unlike other animals, owls’ eyes are immobile or fixed within their eye sockets. An owl cannot move their eyes.ion Offices.
