> Kestrels!! (or, as we used to call them, sparrow hawks)

In British English, sparrowhawks (http://www.birdsofbritain.co.uk/bird-guide/sparrowhawk.htm) (or here) (http://www.rspb.org.uk/birds/guide/s/sparrowhawk/index.asp) and kestrels (http://www.birdsofbritain.co.uk/bird-guide/kestrel.htm) (or here) (http://www.rspb.org.uk/birds/guide/k/kestrel/index.asp) are both still called that, but are different birds. Is that different in American?
