How many Rangers?

Yesterday during after the training course, we had a piwakawaka (fantail) fly into our training room. We couldn't catch it, and it kept flying around the room. The legend is that they are a messenger bringing a message of change, often of death. This one couldn't find the way out even though we closed all the windows and left the door open. 

How many DOC Rangers does it take to catch one fantail? More than we had!
