I do believe it was a horror film

If you like horror movies and want something a little different, Dead Birds might fit the bill. The title is a little odd. At one point the camera zooms in on a dead crow and the screen goes red. This one works on the victims kinda deserving route. The movie is set sometime in the Civil War, somewhere in the fairly deep South. The first establishes the protagonists as a nasty lot. They ride into town and rob a bank, in a particularly brutal manner. This scenes also lets you know that the director likes him some gore.

The group then goes to their hideout, an abandoned house deep in the woods. The leader knows its abandoned because the soldier than owed it died. Turns out terrible things were afoot at the house and the story takes a turn to the Clive Barker. Things get sticky and icky and there are even a few nice little scares. The Civil War setting was novel and allowed for a few nice diversions and character touches. I thought the ending was a nice touch as well.

If you don't like horror movies, skip it, you will be bored and/or disgusted.
