Pacific-slope flycatcher

Caught our third (?) western flycatcher today. With these guys there are a handful of measurements that must be taken, then put into a formula to determine what species it actually is. There are a variety of other features to look at in order to separate western's from other flycatchers, but figuring out if it's a pacific-slope or cordilleran flycatcher is a bit tougher.
