Hi! I am using Mac OS 10.10.5
Using Activity Monitor I see that a process called 'bird' is using about 48% of my CPU. If I quit it, is just starts up again.
I looked it up and saw someone had said using terminal and writing this would help see what the problem was, so I did:
brctl log --wait --shorten

Then terminal went endlessly displaying text. Here is the beginning of that text:

brctl log --wait --shorten
Justins-MacBook-Pro:~ Justin$ brctl log --wait --shorten

I do not understand what any of that means. What can I do to stop this issue?
Many thanks!

"bird" is one of the processes used by iCloud, if it's busy then it's probably working to sync files between your Mac and iCloud. Have you started using or have you made changes to t he contents of iCloud Drive or Photo Library?

I do not do any paid service to icloud so I assume that means there should be very little space being used on it. I have a very fast internet connection with fibre optic broadband, and yet this bird thing has been labouring my computer fans for hours.

I am totally unfamiliar with 'terminal' but the output from tha command I inputted seems to be saying (see details in original mail in the quoted passage from its output) that it is going mental because about every few 0.01's of a second it is trying a failing to open "thumbnail.jpg" - I have no idea why or what that involves, perhaps I deleted some useless file which it now is getting mad about?!
