[mou] Hawk

[h.wang at comcast.net]

Can someone help me identify a pair of hawks on Portland Ave, between Saratoga and Pascal in St Paul?  They were seen from about 2pm till 4:15 today, and the female was still sitting on a branch of the middle of 3 large ?elm trees on the south side of the street, just in front of the Christian Fellowship building. The male was coming and going during that time, and observed to mount the female on one occasion.  There did not appear to be any nest-building activity going on.  Are they a pair of Cooper's hawk?  The female was making pretty consistent calls sounding like "erh, erh, erh".

Thanks.
