Those really hot days of summer can really drain your energy. It is tempting to sit in an air-conditioned room rather than go outside to look at birds. Nesting birds must provide for their young even on those hot days. Insects are plentiful this time of year, so it's a good time to find protein-packed food to feed their offspring. Most birds are most active during the cooler hours of the morning and then again in the evening. During the hottest parts of the day, they take refuge in a shady spot and may be hard to see. A few birds seem to thrive on the heat and persistently sing all day long. Dickcissels sing their repetitive songs from the grasslands even in the afternoon heat. Indigo Buntings are another species that never seems to mind the heat. Vireos can also be persisitent singers no matter what the temperature. Soaring birds like Turkey Vultures take advantage of thermals to search for carrion, which is just as active during the middle of the day as any other time!

With Thanksgiving happening this week, it's time to appreciate the Wild Turkey. While most Thanksgiving dinner tables will feature its domesticated relative, the tradition of a turkey dinner came from times when much more food was provided by hunting wild animals. Perhaps the most well-known admirer of the Wild Turkey was Benjamin Franklin, who campaigned for it to be the national symbol. It fell just one vote short in Congress. Such large birds are charismatic and have many admirers, both hunters and non-hunters.
A turkey flock regularly travels through our neighborhood, and the story is that the former owners of our house had an offer on the house a year before we bought it, but turned it down because of a comment from the would-be buyer about hunting turkeys. We have a flock of 14 that has been seen off and on since this summer, and they have been coming more regularly this fall. The flock appears to be made up of two broods with their mothers, who have been joined recently by a few more, including at least one tom. They feed on seed beneath our feeders and in a neighbor's yard where seed is spread on the front walkway. They also drink from our bird bath--standing on the ground and stretching their necks to reach the water.
Wild Turkeys prefer oak savanna or woodland edges, with acorns being an important food source. They also feed on all kinds of grain and other seeds, berries, other plant parts, insects, and the occasional frog, lizard, or snake. Although they spend most of their time on the ground, Wild Turkeys can fly and often roost in trees at night. Large oaks with spreading branches provide excellent roost trees, another reason oak savanna is one of their preferred habitats.

It's not one of those spectacles like Sandhill Cranes along the Platte River, or warblers along the Gulf Coast in the spring. But fall migration of sparrows is something we can witness here in Iowa, when plants are turning brown and the weather turning cool. Many of our breeding sparrows have already left, but northern populations of species like Vesper and Song Sparrows are moving through. Species like Nelson's and LeConte's Sparrows migrate through Iowa between the northern prairies and their wintering grounds in the southern U.S. American Tree Sparrows nest in the Arctic, and return to the Midwest to winter. Swamp, Harris's, White-throated, White-crowned, Clay-colored, and Savanna Sparrows are some of the other species that can be found here in the fall. Observing all these sparrows involves a little more effort than watching ducks. Most skulk among grasses or shrubs. Finding them requires patience and luck. Skill may be involved in "pishing" or making noises that attract some birds to come out for a look. Lapland and Smith's Longspurs, which are related to sparrows, prefer short vegetation and use camouflage to hide among the dry grasses. They are most easily found by having several people spread out and walk across fields of short, sparse grass to flush out the birds. To those who haven't tried it, this may not sound like a lot of work to see little brown birds. But the subtle beauty of these birds can be appreciated by those who get good looks at sparrows.

Migration is an amazing event in the bird world. We are fortunate to be in an area where so many birds pass through on their way from their wintering grounds to their breeding grounds. Some stop to nest here in Iowa, while others keep going, making Iowa a true flyover state. One of the tantalizing things about migration is that it is so ephemeral. Birds may be here for a few hours to a few weeks to re-fuel on their way north. Often their fate lies with the weather--the wind direction and speed, rainfall, and availability of food. Most songbirds and shorebirds make their long flights at night, and spend the day searching for food. They are less prone to predation that way, and often the wind is calmer. They take off once it's dark and as the sky begins to brighten, they look for a place to spend the day. They prefer a tailwind or no wind at all, and a north wind or rainstorm may keep them in place until the weather changes. You can actually see birds taking off and landing on weather radar. If there aren't a lot of clouds in the sky, the colors you see may represent birds. Go to
http://radar.weather.gov/radar.php?rid=DMX&product=N0Z&overlay=11101111&loop=yes for Des Moines area bird migration. If you check it after sunset or soon after sunrise, you may see an expanding circle in the evening (birds taking off) or a contracting circle in the morning (birds landing). As birds go up or down they break the radar beam and show up as blips. The more birds there are migrating, the more intense the color will be. For a national view, look at
http://radar.weather.gov/Conus/index_loop.php . This will show birds taking off or landing as the sun rises and sets in their part of the country. It can be fascinating, and give you an idea of how many birds are out there migrating.

OK, so there's still a possibility it could snow again, but spring is officially here and the birds know it. After a long, cold, snowy winter, it is welcome relief to hear American Robins and Northern Cardinals singing from almost anywhere in Central Iowa in the morning. Eastern Meadowlarks are claiming their territories in the prairies, and Red-winged Blackbirds are spread out along the highways. Turkey Vultures are being seen, there are reports of Eastern Phoebes and Tree Swallows arriving, and waterfowl have been migrating through for a few weeks. From now through early June there will be new species coming through weekly. Some will be returning to nest in Iowa, while others continue on to breed north of us. A few species, such as American Tree Sparrows, Lapland Longspurs, Snow Buntings, and Northern Saw-whet Owls, actually choose to winter here in Iowa and will be returning north to nest, so we will soon bid them farewell. Resident species are thinking about nesting. Cavity nesters like woodpeckers, chickadees, and nuthatches can get an earlier start due to the extra protection they get from the weather in their sturdy nest sites. Tough birds like Bald Eagles and Great Horned Owls begin nesting in the dead of winter and are fully involved in nesting now. Spring doesn't last, so get out there and experience it throughout the season!

We held the Des Moines Christmas Bird Count on Saturday, 12/26. The purpose is to tally all birds within a 15-mile diameter circle and report the results to the National Audubon Society. This is very useful in monitoring bird population trends. The Des Moines circle is centered at 63rd and University. It basically runs from Saylorville Dam to Lake Colchester (north of Norwalk) and the I-80 rest stop to the fairgrounds. The Des Moines CBC has been held since 1948.
The weather and holiday plans limited the number of participants this year, but we still had a respectable total of 63 species. The Des Moines river and Maffitt Reservoir had open water, so that helped our waterfowl count. Here are the count totals:
Cackling Goose (2); Canada Goose (5733); Trumpeter Swan (7 - record high); Gadwall (1); Mallard (679); Pintail (1); Redhead (2); Ring-necked Duck (2); Common Goldeneye (45); Hooded Merganser (5); Common Merganser (39); Ruddy Duck (1); Ring-necked Pheasant (7); Wild Turkey (56 - record high); Pied-billed Grebe (1); Great Blue Heron (1); Bald Eagle (56); Sharp-shinned Hawk (2); Cooper's Hawk (2); Red-tailed Hawk (53); Rough-legged Hawk (1); Kestrel (4); Merlin (1); Coot (4); Ring-billed Gull (10); Herring Gull (3); Rock Pigeon (387); Eurasion Collared-Dove (7); Mourning Dove (49); Great Horned Owl (3); Barred Owl (4); Long-eared Owl (3); Belted Kingfisher (2); Red-bellied Woodpecker (35); Downy Woodpecker (62); Hairy Woodpecker (16); Northern Flicker (7); Pileated Woodpecker (1); Blue Jay (64); Crow (359 - didn't count the downtown roost, so #'s lower than usual); Horned Lark (10); Black-capped Chickadee (64 - record low); Tufted Titmouse (19); Red-breasted Nuthatch (2); White-breasted Nuthatch (44); Brown Creeper (6); Carolina Wren (7); Robin (18); Starling (167 - didn't count the downtown roosts, so #'s lower than usual); Cedar Waxwing (27); Tree Sparrow (96); Song Sparrow (12); White-throated Sparrow (9); Harris's Sparrow (3); White-crowned Sparrow (2); Dark-eyed Junco (260); Lapland Longspur (4); Snow Bunting (1); Cardinal (148); Red-winged Blackbird (7); House Finch (37); Goldfinch (90); House Sparrow (270)
Many thanks to those who participated in the field and to those who reported feeder birds.

On Saturday, Oct. 24, nine people searched for Smith's Longspurs at Neal Smith National Wildlife Refuge east of Des Moines. These birds migrate through Iowa as they travel between wintering grounds to the south and breeding grounds in the arctic. Searching consists of spreading out and walking across a field with short, sparse grasses and other vegetation. Two small flocks were located at the refuge, one with seven birds, the other with five birds. These are the first Smith's Longspurs found on the refuge in the fall, probably because nobody has done a targeted search for them before. They may be more common this time of year than we realize, but it takes effort to find them. Other birds seen include Prairie Falcon, Le Conte's Sparrow, Lapland Longspur, American Pipit, and Horned Lark.
