Joe, To complete the reference list, don't forget Waterfowl by Madge and Burn. But to get back to your original request, stay tuned for David Sibley's new field guide, which I believe is due to be published this year. It will feature his plates, an example of which you can find in Birding, Vol. 28, #3, Pages 196-208, 1996, Field Identification of the Sharp-tailed Sparrow Complex. This will be a valuable guide.
