Hi Manon, actually I believe that you have a Broad-winged hawk. Heavy dark barring on the chest along with a short tail and a broad band points to this buteo imho. Hope this helps
I looked at this earlier, Andrew but was interrupted before I could respond. I totally agree with you.
FYI - There will be rapor identification workshop at the Ganong Nature Park in Charlotte County on August 20 from 7-9PM.
