cloudd and bird processes hogging the processor?

I have a fresh installation of Yosemite on a mid-2010 MBP. I'm seeing two processes, "cloudd" and "bird," consistently running the proc at about %60 and %40 consistently, along with the expected heat, fan and battery consumption. My first thought was that this was tied to iCloud Drive indexing, but we're deep into hour three at this point, which seems little excessive to index less than .5G in data.

Anyone else seeing this?
