A bit of good news for the day — Iowa's osprey population is ticking up.
Why it matters: These birds of prey struggled in the 1950s and 60s due to the pesticide DDT, which thinned their eggshells.
State of play: While DDT was banned in 1972, the biggest challenge facing ospreys now are cell phone towers.
The solution: The DNR and volunteers are collaborating with cell phone companies when work on a tower needs to get done.
