1) “Nature,” 8 p.m., PBS. All of Kenya, we’re told, has fewer than 30 “super-tusker” elephants — giants (shown heree) with 10-foot tusks. This film follows the post-drought lives of three. It’s slow, but has big moments of lust, rage and parenting. It’s followed by reruns — a terrific “Nova” on UFO’s and the first half of a “Secrets of the Dead” involving Nazis’ stolen art.
2) “The Masked Singer,” 8 p.m., Fox. Last week’s opener revealed one singer (baseball great David “Big Papi” Ortiz) and started to unmask another, a duo. Now we’ll see that and one more, in an hour that also obsesses on the “Fear Factor” reboot, which repeats its opener at 9.
3) “Abbott Elementary,” 8:30 p.m., ABC. Last week, the school re-opened in a former shopping mall. Now parents are unhappy — as Janine and Gregory learn from the PTA. That follows “Shifting Gears,” with Matt meeting the opinionated spouse of a high school classmate.
4) “Dirty Talk,” 9-10 p.m., ABC. For a time, daytime talk shows devolved from the intellect of Phil Donahue and Oprah Winfrey to the shouts, fights and paternity tests of the ’90s. This three-week series talks to Maury Povich, Sally Jessy Raphael and more, including producers of the Jerry Springer, Ricki Lake and Geraldo Rivera shows.
5) ALSO: “Chicago Med” (8 p.m., NBC) sees road rage send three people to the emergency department. “Harlan Cohen’s Final Twist” (10 p.m., CBS) reruns the hour that ran at 8 p.m. Tuesday, with a successful businesswoman slaim. Movies include two gems — “The In-Laws” (1979), 8 p.m. ET, Turner Classic Movies; and “Fargo” (1996), 9 p.m., HBO.
