Modern avian radiation across the Cretaceous-Paleogene
boundary. The Auk 124(4):339–341, 2007

Analysis of the paleoenvironment of the C-P boundarsy
fossil record coupled with sea-level change
considerations suggests highest abundance of
neornithines 65 mya was in coastal habitat.

[Fits the general picture: "higher waterbird"
radiation starting somewhat off before "higher
landbirds", and "waterbirds" in general having had
higher (eco)morphological diversity around C-P. The
morphologically conservative Galliformes making up
much of the "landbird" diversity then, with
Passeriformes and their crown-group relatives being
barely distinct if at all]
