        There is a good article on the various crossbill  calls on E-bird 
www.ebird.org .  Its the second story on the home page.
        Pine Siskins and Red-breasted Nuthatches are following the winter 
patterns that were predicted for them in late summer based on the available 
food supplies in Canada.  Siskin food supplies were scarce while nuthatch 
supplies were good, therefore there should be a major movement of siskins, 
but not of nuthatches which seems to the case in Maryland.
       To see the present distribution of these species in North America go 
to www.ebird.org , click on View and Explore data, then Map.  Key in the 
species and set the time period you want and a distribution map will appear.
