State of Iowa

Iowa is a landlocked state in the upper Midwestern region of the United States. It borders the Mississippi River to the east and the Missouri River and Big Sioux River to the west; Wisconsin to the northeast, Illinois to the east and southeast, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north. It is the 26th largest with an area of just under 146,000 Km² (56,000 square miles) and the 31st most populous of the 50 US states, with a population of 3.2 million people. The state’s capital, most populous city, and largest metropolitan area fully located within the state is Des Moines with less than a quarter of a million residents. A portion of the larger Omaha, Nebraska, metropolitan area extends into three counties of southwest Iowa. Iowa has been listed as one of the safest US states in which to live.

Several natural lakes exist, most notably Spirit Lake, West Okoboji Lake, and East Okoboji Lake in northwest Iowa. To the east lies Clear Lake. Man-made lakes include Lake Odessa, Saylorville Lake, Lake Red Rock, Coralville Lake, Lake MacBride, and Rathbun Lake. Before European settlement, 4 to 6 million acres of the state was covered with wetlands, about 95% of these wetlands have been drained. Iowa’s natural vegetation is tallgrass prairie and savanna in upland areas, with dense forest and wetlands in flood plains and protected river valleys, and pothole wetlands in northern prairie areas.

Most of Iowa is used for agriculture; crops cover 60% of the state, grasslands (mostly pasture and hay with some prairie and wetland) cover 30%, and forests cover 7%; urban areas and water cover another 1% each. The southern part of Iowa is categorised as the Central forest-grasslands transition ecoregion. The Northern, drier part of Iowa is categorised as part of the Central tall grasslands. There is a dearth of natural areas in Iowa; less than 1% of the tallgrass prairie that once covered most of Iowa remains intact; only about 5% of the state’s prairie pothole wetlands remain, and most of the original forest has been lost. The explosion in the number of high-density livestock facilities in Iowa has led to increased rural water contamination and a decline in air quality.

Iowa has a humid continental climate throughout the state with extremes of both heat and cold. The average annual temperature at Des Moines is 10 °C; for some locations in the north, such as Mason City, the figure is about 7 °C, while Keokuk, on the Mississippi River, averages 11 °C. Snowfall is common, with Des Moines getting about 26 days of snowfall a year, and other places, such as Shenandoah getting about 11 days of snowfall in a year. Rainfall across the state ranges from an average of 28 inches to 38 inches. Spring ushers in the beginning of the severe weather season. Iowa averages about 50 days of thunderstorm activity per year with the annual average number of tornadoes being 47. Iowa summers are known for heat and humidity, with daytime temperatures sometimes near 32 °C and occasionally exceeding 38 °C (the highest ever being 48 °C), whereas average winters in the state have been known to drop well below freezing, even dropping below −28 °C.

Birding Iowa

Located between two major river systems in the heart of the upper Midwest, Iowa offers a bit of everything for birders. Many species are at the limit of either their east-west or north-south range in this state.

Along Iowa’s eastern border, formed by the Mississippi River, one can find a typical sampling of the species found in eastern North America. The Mississippi Flyway is a major migration route for waterfowl, raptors, shorebirds, and most passerines. Extensive bottomland forest is typical. The eleven locks and dams on the Mississippi each have large pools above them that accommodate great concentrations of waterfowl. Vagrant winter Gulls are found quite routinely along the river. Large numbers of Bald Eagles winter here, with this species now ranging over the entire state. The western border of the state is formed by the Missouri River. The Loess Hills, ranging north along the river, are a unique geological feature, and attract many western species not found in other parts of the state. The Missouri flyway is the primary migration route for Snow and Ross’s Geese, as well as many waterfowl.

Historically a prairie state, Iowa is now extensively farmed. The most recently glaciated prairie pothole region, in the Northwest part of the state, is home to many waterfowl, gulls, terns and wetland birds. Its extensive marshes and pools attract shorebirds in migration. The steep bluffs and hills in the Northeast Palaeozoic Plateau are the best areas to find Golden Eagle, Ruffed Grouse and Pileated Woodpeckers.

The most comprehensive and valuable website for Iowa birders is the Iowa Birds and Birding Page, sponsored by the Iowa Ornithologists’ Union. It includes information about the IOU, publications available, the state Rare Bird Alert; archives and an extensive list of e-mail addresses of birders who are willing to assist others, birding sites around the state, the official Iowa checklist, activity of the Records Committee, local birding groups, links to other Iowa websites, and more.

  • Hitchcock Nature Centre Hawkwatch

    WebpageSatellite View
    There is an annual hawkwatch at the Hitchcock Nature Centre, which is located in the Loess Hills near Crescent. It records an average of slightly over 10,000 hawks, eagles, and vultures of 18-20 different species every fall. Large flights of waterfowl and other avian species also occur there. It is certainly a site of national significance and has been listed among the top hawkwatches in North America by Wildbird magazine and was Iowa's first IBA.

    Report
    My wife and I spent one month in USA from June 24. We landed in Denver Colorado where a Chevrolet waited on us. It served us so well all the 9600 km – no problems, no accidents. We had a great time in every respect, also due to the fact that the weather was on our side – almost no rain for a month. But there was a slight “problem”, it was too hot, as a heat wave followed us part of the time, even at high altitudes. Denver is situated on about 1650 meter, and there we had around 40 degrees (104 Fahrenheit) for several days, beating all the previous records.
