1) “Nature” 9 p.m. PBS. The osprey is an amazing creation. With a six-foot wingspan, yet weighing only three pounds, it’s a fierce flying machine. It’s the one bird that can dive down, completely submerge and emerge with a fish. In this beautifully filmed hour, a male commutes 4,000 miles to a Connecticut reunion with his annual summer mate. They raise three fledglings, while he also chases off two bald eagles (much bigger than he is) and even scatters an entire cormorant colony.
2) “The Conners,” 9 p.m., ABC. Ever since its “Roseanne” days, this show has prided itself in big Halloween episodes. Now the home is decked out for the holiday, amid the usual troubles: A leaky roof has kept Dan and Louise from leaving on their honeymoon.
3) More Halloween comedies, ABC. On the “Goldbergs” (8 p.m.), Adam lost his Halloween spirit after the death of his beloved grandfather (who was played by the late George Segal); his mother tries to get the other grandpa (Judd Hirsch) involved. There’s much more, including an encounter with Elvira, Mistress of the Dark. Then “The Wonder Years” (8:30) has an eerie camping adventure and “Home Economics” (9:30) sees Connor sharing the holiday with his ex-wife.

.5) And more. The second World Series game is 8:09 p.m. ET on Fox, with the Houston Astros hosting the Atlanta Braves. “A Million Little Things” returns at 10 p.m. on ABC, after a week off; Gary tries to make things right for Sophie (Delilah’s daughter), with repercussions. And at 8 p.m.ET, Turner Classic Movies has “Carl Laemmle,” profiling the man who convinced tiny companies to combine. He ran Universal Studios for 22 years, produced the early-’30s horror classics and created the studio tours.
