[Falcons] Amur Falcon Migration 2016

How to these charts compare to those of Eurasian Hobby over the same period?

Sorry I meant the graphs with numbers over time or per week Geoff.

I have just seen the yearly graph on p. 264 of the HKBR 2014. I was wondering if number of observations of Hobbies had dropped as number of Amur observations had gone up, perhaps once observers were more aware of the potential for Amurs to occur, but this is not the case.
