(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.
