(Iowa DNR News) – Drivers are advised to stay alert as they travel Iowa’s roadsides over the coming weeks. Autumn deer behavior, crop harvest and peak travel times for motorists combine to hike the risk of vehicle-deer collisions in Iowa. From the middle of October until the third week of November, Iowa bucks become more active in the pursuit of does during the breeding season. Motorist may be distracted by the first deer that crosses not seeing the pursuing buck. This adds to multiple scenarios of fast moving, unpredictable deer crossing highways.

The crop harvest is also in full swing, concentrating deer into remaining cover that is often brushy creeks, trees or fence lines which often intersect with roads. A third factor will be the change away from daylight savings time on November 7, placing more Iowans behind the wheel during the deer-heavy dawn and dusk periods.

A few ways to give drivers an edge during this period are to reduce speed, increase following distance from other cars, and to sweep eye movements from ditch to ditch, especially during those low light periods and when approaching those brushy or tree lined ‘funnels’ near roads. Drivers are also encouraged not to ‘veer for deer,’ leaving the lane of traffic could cause a collision with another vehicle or a roadside obstacle, such as a utility pole or culvert.

Iowa’s deer herd is managed to provide a harvest of between 100,000 and 120,000 annually, that is achieved by providing additional opportunities for hunters to harvest does. Last year, Iowa hunters reported harvesting nearly 110,000 deer.

(Iowa DNR News) – Fun abounds statewide for those in search of color and good times outdoors. Enjoy a fall drive and take in all the beautiful colors this weekend. Plenty of fall color is lingering in northeast Iowa. Fall color will be at its peak in central Iowa this week.  Urban maple is showing a few brighter reds and oranges in southeast Iowa. Hard maple is at peak color in the urban landscapes in south-central Iowa.

Warm nights have slowed color changes in west-central and southwest Iowa. Yellows are just starting to appear on the bottomlands in the Missouri River Corridor.

(Radio Iowa) – One of the sure signs of fall, Iowans are seeing huge congregations of birds filling the morning and evening skies, giant clouds of feathered creatures that often take several minutes to pass. Steve Dinsmore, a central Iowa ornithologist and bird watcher, says it’s typical during this time of the year to spot birds migrating in tremendously large numbers over Iowa. “Those could represent a number of different species of birds,” Dinsmore says. “One of them is European starlings, so we call those a murmuration of starlings. We also, right now, have very, very large numbers of blackbirds, primarily redwing blackbirds and common grackles, and also other species that are also migrating. Those birds, just like starlings, form these large, wavy, meandering flocks.”

Dinsmore is a professor of Natural Resource Ecology and Management at Iowa State University. He says birds of a feather do flock together for several reasons. “One of them certainly deals with predator avoidance, a sort of safety-in-numbers component,” Dinsmore says. “These birds also feed en mass so one of the other advantages of them associating in flocks is the transfer of information about foraging sites or feeding sites. They do that through these large flocks as they’ve moving to and from roosting and feeding areas.”

The miles-long undulating flocks are fascinating to watch and may contain tens of thousands of birds, perhaps more. “One of the real fun questions to try and answer is, ‘How many are there?’ and certainly, those flocks are very, very large, to the point where you can’t count individuals,” Dinsmore says. “Sometimes, we use estimation techniques or approximation techniques. Pushing 100,000 is pretty unusual but there are records in the hundreds of thousands and some estimates even up to a million individuals.”

Some Iowans who live in larger cities may even be surprised to spot wild turkeys in their back yards, though they’re typically thought of as more of a “country” bird.
