They are. The needle will not work on them, as they are not activated abilities.

And here's some confirmation, from Pithing Needle's rulings on Gatherer, just in case:

10/1/2012 Activated abilities include a colon and are written in the form "[cost]: [effect]." Triggered abilities and static abilities of the named card work normally.
