Mysterious bumper sticker

I saw a bumper sticker the other day that I haven’t been able to figure out. It read simply “I [heart shape] [silhouette of bird] rock”. Any clues?

It seems like a reference to a local landmark. Eagle Rock, Rooster Rock, Goony Bird Rock-who can tell if we don’t know where you are posting from?
What type of bird does the silhouette look like?

There are several online references to a bumper sticker for Eagle Rock.

Ah. There is an Eagle Rock, Pennsylvania, which is relatively near me (I’m in Philly). The bird silhouette certainly could’ve been meant to represent an eagle, although it wasn’t so clear that I instantly recognized it.
