The best thing to do is leave it alone and let it become the habitat that nature intended. NOT always possible in our urban forest! I like to see them left full as possible, seedpods cut out, and done annually in July after bud break of the seed pod. If they are cut too early, a brand new set of pod clusters will arise seemingly out of thin air...and LOTS of it.
A common misconception among consumers and tree workers alike is that if you take more fronds, the tree will "last longer" until more pruning is needed. This is what causes trimmers to "carrot top" them, leaving the fronds at a 45 degree angle and even worse. I have seen palms with ONLY the center Spike left. Years of repeating this practice leads to bottlenecking of the trunk. They are scary enough at 60-70 feet tall with a 10 inch diameter spar, much less climbing past areas where the tree bottleneck to an even smaller diameter...and its hard as a rock in those areas so your SPIKES don't stick well.
Another reason climbers OVER trim is because to leaving the head full means you must cut the seed pods out of a full head, trying to avoid nicking the surrounding fronds with your handsaw. It doesnt take much of a nick to cause the frond to collapse and turn brown in the next gust of wind.
I swear I could write volumes on palm climbing...the horror
