Ring-bill, April 23, 1955
II

[[Left margin - cross-hatching, with two solid vertical lines]] When one mate joins the other on the ground, the ground bird may give TC toward the flying one, and the flying one may give Landing Call.

Males of some pairs did a lot of M. Usual semi-hostile-appeasing situations.

Precop, of course, is usual mutual FB with T. [[male symbol]] often, at least, with stretched neck quite high, no real bobbing. [[female symbol]] low

Post-cop U-HF business. 
[[/Left margin - cross-hatching, with two solid vertical lines]]

[[left margin: two exclamation points to left of cross-hatching]] No signs of ritualized hostile movements or postures during the aerial "flitting"
