These guys have been on my case before:
I have seen them around the parking area dishing out punishment on somebody's car. (They usually peck at shiny cars, possible trying to straighten out that "other guy" in the car's reflection.)
They like to keep a camera under good observation and will fill up the memory card in no time, if they deem it necessary.
I think the porcupines might have reported me a few days earlier because I suspect some of their spies where sent to do some reconnaissance work:
Here are some videos of the Red-eyed Dove pretending to feed in front of the camera:
Video: I can see right through this bad acting
Even the Olive Thrush, a friend to many gardeners, has joined their ranks:

Finally the officer walks past the camera, clearly giving me a warning to back off:

After such an onslaught I decided that it's probably best if I move my camera to a new location. I will return for some more porcupine picture when things have cooled down a bit...
