LOS ANGELES - A different kind of hero is moving to Wednesday nights on WB.

Starting in January, Angel will move from Sunday nights to 9 p.m. Wednesdays, replacing the canceled Birds of Prey. The reality show High School Reunion, from Bachelor producer Mike Fleiss, will take the 9 p.m. Sunday spot for January and February.

After debuting to an audience of more than 7 million, female-superhero series Birds of Prey has steadily lost viewers since then, falling to an average of about 5 million for the season. However, the network was encouraged by the young male viewers the show was able to draw in the face of competition from The Bachelor and Fastlane.

"We believe Birds of Prey proved there's a fantasy audience there and a male audience there," WB Entertainment president Jordan Levin says.

The problem, Levin says, was that they failed to find a "strong writing showrunner" who worked well with creator Laeta Kalogridis, a feature-film writer (Tomb Raider) making her first foray into television.

"We think we can attribute the erosion of Birds of Prey, quite frankly, to a failure of execution," he says. "We think we had a very strong concept and just failed to execute it, and audiences abandoned the show as a result."

High School Reunion brings together 17 people from a suburban Chicago high school's class of 1992. Ensconced in an estate on Maui, they'll be able to re-establish old friendships, pursue a high-school crush or exact revenge on a bully. Repeats of each episode will air at 8 p.m. Thursdays.

The Thursday repeats will bump Family Affair and Do Over, which are going on hiatus until spring. Another new series, The Surreal Life - a Real World-style series featuring B-list celebrities - will join JKX: The Jamie Kennedy Experiment to create an all-unscripted night.

WB also has plans to unveil the family comedy The O'Keefes, an improvised comedy called On the Spot, and an action drama The Black Sash later in the season. The Black Sash could fill the 9 p.m. Sunday spot if Angel does well on Wednesdays.
