In addition, there are numerous other bird species associated with forests or savannas that are listed in the breeding bird surveys that were done in 2003 and 2006

Birds of the Oak Savanna. We have emphasized that the oak savanna habitat is one of the rarest vegetation communities. Because it is now so rare, bird species that once lived in oak savannas, such as the red-headed woodpecker (Melanerpes erythrocephalus) have either disappeared or have adapted to other habitats. Fortunately, at Pleasant Valley Conservancy the red-headed woodpecker appears to have made a nice recovery since we began restoring oak savanna. We started to see resident pairs of these attractive birds after the west part of our bur oak savanna was cleared and now they are residents. In 2003 we saw immature birds for the first time, confirming that the are nesting here. They are also usually found in our Christmas bird count for the Madison Audubon Society.

In July 2004, a team led by Richard King, a specialist on red-headed woodpeckers from the U.S. Fish and Wildlife Service, made a survey at Pleasant Valley Conservancy. His group found numerous individuals and located and marked two trees with confirmed nests. Both trees were dead birches (Betula papyrifera). King and co-author William Mueller have published an article on the "redheads" in the August 2005 issue of Wisconsin Natural Resources. This article has some nice things to say about Pleasant Valley Conservancy. Click here for a pdf version.

Wild turkey. The wild turkey (Meleagris gallopavo), a native species of the New World, is the largest game bird in North America. It has made a remarkable recovery in southern Wisconsin since it was first reintroduced in 1976. According to the Wisconsin Department of Natural Resources, one important reason for the turkey success has been intensive habitat improvement, supported to a great extent by private landowners. Although turkeys are adaptable animals, they prefer oak forests, especially those that are interspersed with openings. Thus, the oak savanna habitat is ideal.

Turkeys need good roosting and nesting habitat and dependable food sources. Preferred roosting habitat is large trees with horizontal limbs, such as open-grown (savanna) oaks. For nesting, turkeys need moderately dense understory vegetation that helps conceal the nest but at the same time allows the hen to survey her surroundings.

Since we began restoration at Pleasant Valley Conservancy, we have observed turkey nests every year. Turkeys have nested on the restored south slope prairie, as well as on the restored savanna. One year we observed four separate nests, all being tended at the same time. Females with broods of young are seen almost every year.

Ruffed Grouse The ruffed grouse (Bonasa umbellus) is another bird that prefers open woods. According to the Ruffed Grouse Society, they thrive best in forests that are kept open by frequent clearing or fire. We hear grouse drumming occasionally and nests have been sighted. One year there was a ruffed grouse nest within less than 100 feet of a turkey nest, both on the White Oak Savanna (unit 12A).

Sandhill Crane. The sandhill crane (Grus canadensis) is a conspicuous summer resident of the wetlands at Pleasant Valley Conservancy. Every year for at least the past twenty years, sandhills have nested on our marsh. Most years they are successful in raising a one or two chicks.

Our nesting sandhills do not confine themselves just to our marsh. They move up and down Pleasant Valley Creek as well as East Blue Mounds Creek. While pulling weeds on the south slope, we often stop to enjoy their characteristic call as they fly up or down the valley. The 2005 photo below was taken by Kathie Brock at the marsh edge next to our newly planted wet-mesic "Crane Prairie".

Kestrels The kestrel (Falco sparverius) is a small insect-eating hawk that lives in open country and woods edges. The American kestrel is a colorful bird, as can be verified by looking at its image on the one cent US postal stamp (see photo below).

According to the Atlas of the Breeding Birds of Wisconsin (Wisconsin Society for Ornithology, 2006), kestrels are usually associated with savannas and grasslands, but can be found in almost any open habitat. Pleasant Valley Conservancy is thus an ideal area, since our vegetation grades from savanna through dry open prairie into wet prairie and marsh. Our nest boxes are positioned at the edge of the wet prairie.

Several years ago we installed two kestrel nest boxes and were pleased to have a nesting pair. In spring 2007 we had kestrels using both our nest boxes. See the photo below for a design for a kestrel box installation, courtesy of Mark Martin of Madison Aububon Society. Starlings frequently evict kestrels from their nesting cavities, but their predations can be reduced by siting nest boxes high in the open, orienting to maximize light entering the cavity. Thus, our boxes on high poles are ideal. The pole is constructed in two parts with a bolt holding them together. By loosening the bolt, the top part pivots down so that the box can be cleaned. We place fresh wood shavings in the box in the spring.

We have a good view of the kestrel box from the front porch near our field station. Folks enjoy watching the kestrels behave while they are eating lunch.

The day after the above photos were taken, the baby kestrels fledged (see photo below). A few moments after the photo below was taken the baby disappeared into the tall weeds. Hopefully, he survived his first outing and is on the way to becoming a contributing member of kestrel society!
