A hybrid is the offspring of two different species, while an intergrade is an offspring of two distinct phases/morphs/subspecies of the same species. For example, the offspring of a Mallard and Wigeon would be a hybrid, whereas the offspring of a Yellow-shafted and a Red-shafted Flicker would be an intergrade.

What is the difference between an intergrade and a hybrid?   Duh....  Kathleen

Quoting Larry Lade :
Just wanted to clarify that the one flicker was an intergrade (not hybrid) bird.

This morning Jack and I together with Brad, Jake and Jacob (three MWSU students) netted and banded fifteen (15) birds. As an added attraction Dana and Ethan from the Missouri River Bird Observatory (Marshall, MO) assisted us with our presentation of bird banding operations to 23 high school students and their teachers from Central (Saint Joseph) & Lawson, MO. The highlight seemed to be the two Northern Flickers which were netted and banded. One was a regular, female, yellow-shafted and the other appeared to be a hybrid yellow X red-shafted female bird. Close examination determined that the Philadelphia Vireo/Warbling Vireo (?) was indeed a Warbling by looking closely at the # 10 primary feather. (Longer on the Warbling compared to the Philadelphia.) Other birds for the kids to observe up close and personal were House Wren, Field Sparrow, Orange-crowned Warbler, Northern Cardinal and American Robin. (I may have forgotten some of the birds, as I do not have a list of them at hand right now.) A Cooper's Hawk flew over our area a couple of times while we were banding.

After the banding, Dr. John Rushin took the students afield for further natural science adventures.
